Grayed-Out Sleep and Hibernate Options on Windows 7 After Updating Graphics Driver

- by Maxim Zaslavsky

I have a Gateway M275 Tablet PC, on which I've installed Windows 7 Ultimate. The laptop is quite old, so there aren't any Win7 drivers for it, not to mention any Vista drivers. Win7 has been working for some time, but I noticed that my video output wasn't working. I went into Device Manager and found that I didn't have a driver for my video card: it just recognized it as the standard one. I searched online and found an XP driver for it, released by Gateway. Device Manager accepted this driver and prompted me to reboot. After that, I noticed that my Sleep and Hibernate options in the Shut Down menu have been grayed-out. I looked online and found that many people are attributing this to display drivers, as such an old driver would surely not be compatible with the standby procedures Windows 7 uses. To make it clear: I was able to Sleep and Hibernate before updating the drivers; now, I can't. Running powercfg /a gives me, "An internal system component has disabled this standby state," for each available standby mode. Is there some way that the driver can be modified to support hibernation? The new driver fixed my video output problem, but I guess hibernation is more important for me. If not, what steps should I take to remove the driver and just leave the standard Windows one, which previously supported hibernation and sleep on this computer? Thanks in advance.

Dell laptop keyboard doesn't work

- by Tam

I'm trying to fix my in-laws laptop, it's a Dell Studio 1745 that's running Windows 7 64 bit. The problem is that most of the keys on the keyboard do not work. The function keys work and the caps lock and numpad keys work, but no other keys do. If I hit the F2 key enough times when starting up, I can get to the BIOS, but after that even the function keys stop working. If I let it go all the way to the Windows login screen, I can see that the caps lock and num lock work - little images on screen actually appear, but they don't toggle the state of the key, i.e.,capslock is always off, numlock is always off. Using the fn+function combo works, so changing the brightness, etc. works fine. I'm stumped. I've tried disconnecting power and battery and leaving it for an hour or so before starting up but that hasn't helped either. Also - this might be a red herring - the touchpad is failing as well, the MS Device Manager says that it's failing with status 10, "unable to start device"

GRUB reporting wrong partition type

- by plok

It all started when I had to replace one of the disks that the software RAID 1 on this machine currently uses. From that moment on I have not been able to boot to the Windows XP that is installed on the fourth hard drive, /dev/sdd. I am almost positive that the problem is related not to Windows but to GRUB, as if I unplug all the other hard drives so that the Windows XP disk is now /dev/sda it boots with no problem. The problem seems to be that GRUB detects a wrong partition type, which I understand suggest that something is really messed up. This is what I get when I try to follow the steps that until now had worked like a charm: grub> map (hd0) (hd3) grub> map (hd3) (hd0) grub> root (hd3,0) Filesystem type is ext2fs, partition type 0xfd 0xfd? That doesn't make sense. /dev/sdb and sdc are 0xfd (Linux raid), but not /dev/sdd: edel:~# fdisk -l [...] Disk /dev/sdd: 250.0 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00048d89 Device Boot Start End Blocks Id System /dev/sdd1 * 1 30400 244187968+ 7 HPFS/NTFS edel:/boot/grub# cat device.map (hd0) /dev/sda (hd1) /dev/sdb (hd2) /dev/sdc (hd3) /dev/sdd I have been trying to work this out for hours, to no avail. Can anyone point me in the right direction?

why would resetting the Netgear N300 router fix my Win 7 laptop's slow wifi?

- by rjnagle

In the past day the wifi download speeds of my Win 7 HP 64 bit laptop have slowed considerably. I am trying to troubleshoot the problem and to figure out whether it's hardware related (i.e., is the Intel(R) Centrino(R) Wireless-N 2230 the problem?) or router related. I have a Netgear N300 router connected to my modem. I'm using Speedtest to measure my speed. First, during my problem state, my ipad can download and upload at normal speeds. It's only my Win 7 laptop which is having problems. Because my ipad downloads at normal speeds, that would tell me that the problem is specific to the laptop (either HW or SW). But when I restarted my Netgear router, the laptop wifi problems disappeared. That just doesn't make sense. If we know that one device can connect properly to the router, why would a laptop have problems? What are some possible reasons why this might happen? Also, during my problem state, I noticed that on my laptop upload speeds were faster than my download speeds. Anybody have a guess about what might cause upload speeds on one device to be faster than another? Is there any actions i could take (or options to enable) so this problem won't occur. (I initially thought my problem might be software related or memory related -- Norton AV or browser plugins. But even after I disabled everything and made sure memory footprint was minimal, the slowdown was still occurring -- and it solved itself altogether when the router was reset).

Fixing damaged partition table

- by dr4cul4

This is continuation of Recover Extended Partition , but this time I have different problem related partition table it self. I managed to restore partition that I needed and backed up files that were crucial to me (at least those that I had space to store somewhere) OK now get to the problem. My partition table is corrupted, booting RIP Linux I can mount it in truecrypt (and other ones that recovered), but that's basically it. When I launch GParted I have unallocated drive.

"Document in ADF" on Canon MX340

- by Michael Donohue

I have a Canon MX340 multifunction printer. Recently, it keeps saying "Document in ADF" when I turn on the printer. I've tried clearing this multiple times, but as soon as the feeder wheels stop turning, in an attempt to clear the document feeder, it just pops up the same error again. This is particularly annoying, as it blocks all functions on the device - I cannot print, even though printing has no interaction with the document feeder. I've opened up the feeder device, as much as can be done with fingers alone. There just doesn't seem to be anything in there. I ran a sheet of paper through about six times, just to see if some dust might be getting in the way, and I've blown out the feeder with air. Still nothing. At this point, I don't care too much about the ADF working, I just want to disable whatever sensor is tripping this error message. Any ideas? I found this thread online, where a user has the same problem. But no resolution was reached there.

initrd problem and Kernel panics after openSUSE 11.2 upgrade.

- by unixbhaskar

Once I have done the upgrade form openSUSE11.1 to openSUSE11.2 by doing this: zypper dup Now I tried to boot the system and it failed sync with VFS and kernel panic, so clearly a initrd problem . if I'm not mistaken. Now a bit of explanation about the problem: while upgrading it shows me the error updating initramfs( I forgot the exact error or might be warning).Oh yeah it shows some grub warning too. I have had been doing that from a chroot environment.. with all the required file mounted in proper place in the chroot environment. Now .after bit googling and painfully looking the susegeek.com forum and opensuse.org forum I have decided to recreate the initrd ...but the fellow called "mkinitrd" is real real crap as I hev been pointed out by few forum members. I tried to make an initrd image by myself, failed to do so .as it shows error that device not found( if I boot into suse live cd and mount the partition ) then I tried from the chrooted env and it says "there is no space left on the device" A bit bemused :( yeah most of you pointed it right may lack of knowledge of mine. Kindly suggest me and show me steps to do it correctly and get opensuse11.2 up and running. TIA

Trying to retrieve data with a thermaltake blacX enclosure: Windows 7 believes the drive to be "uninitialized"

- by Peeter Joot

I have a laptop that won't boot. It appears to be a power problem ... laptop auto-turns-off within about 10 seconds of pressing the power button (with power buttons lighted temporarily and no display with or without external monitor). I've followed the dell troubleshooting guide which suggested reseating the memory modules and the hard drives, but that didn't help. Before trying to have the laptop serviced, I wanted to get some data off off the hard drive. I bought a thermaltake blacX enclosure, intending to use this to both use to retrieve the drive data with, and then later use as external storage. Following the instructions (insert cables, insert drive power on) goes fine, and Windows 7 on another laptop installs the device driver software. However, no drive letter shows up in 'Computer'. Under Computer-manage-storage I see the drive is there, and there's an option to "initialize" the drive. The Windows "initialize" dialog gives me the option to pick between "MBR" and "GPT" partitioning, which sounds like a good way to destroy the data on the drive. I'm thinking that I've purchased the wrong device for the job (or that my old drive is damaged). The old drive to recover info from is a Western Digital 500G/7200rpm SATA drive if that is relavent. Both the original laptop and the one I'm using for recovery are running Windows 7. Does anybody have experience with using a blacX enclosure to recover data off an already formatted drive?

redirecting output from telnet / nc to file in script fails when cron'd

- by qhartman

So, I have device on my network which sits there listening on a port for a connection, and when a connection is made it dumps ascii data out. I need to capture that data to a file. I wrote a dead simple shell script that does this: #!/bin/bash #Config Variables. Age is in Days. DATA_ROOT=/root/data FILENAME=data_`date +%F`.dat HOST=device COMPRESS_AGE=3 #Sanity Checks if [ ! -e $DATA_ROOT ] then echo "The directory $DATA_ROOT seems to not exist. Please create it." exit 1 fi if [ -e $DATA_ROOT/$FILENAME ] then echo "You seem to have extracted data already today. Aborting" exit 1 fi #Get Data nc $HOST 2202 > $DATA_ROOT/$FILENAME #Compress old Data find $DATA_ROOT -type f -mtime +$COMPRESS_AGE -exec gzip {} \; exit 0 It works great when I run it by hand, but when I run it from cron, it doesn't capture any of the output. If I replace nc with telnet I see the initial telnet headers about escape sequences and whatnot, but not the data. Ideas? I've tried forcing bash to act like an interactive shell with -i. I've tried redirecting both stderr and stdout. I know it's got to be some silly simple thing, but I'm utterly failing. This is driving me nuts... EDIT I also just noticed that the nc processes from all my previous attempts at this have been siting sleeping, and when I killed them, cron sent me a bunch of non-sensical error messages. At least now I have something to dig into!

Dedicated Mouse and Keyboard on Virtual Box VM

- by Myersguy

To all super users, Currently I am trying to run virtual box on my second monitor, with a dedicated mouse and keyboard. However, doing so has not proven easy. There has been times where the mouse works, but not the keyboard, vice versa, or nothing works at all. The biggest problem I am running into is this: When enabling the USB mouse and keyboard from the VM, I get an error: 'USB Device is busy with a previous request.' The only thing that is using second mouse and keyboard, however, is Windows. The other error I have received stated that the VM was unable to create a proxy for the device. Additionally, the VM occasionally will disable the secondary keyboard entirely, requiring me to unplug and replug it into my PC to re-enable it again. Keyboard auto-capture is disabled, and while a solution I was reading online stated to turn off mouse integration, that option is grayed out on my machine. Any help would be appreciated. Thanks. /firstquestion.

Help with routing table

- by user68752

I have tried to find the answer to my question but not really found a clean and easy solution. I have a box (Ubuntu headless 10.04.1 server, with one Ethernet port) on LAN behind a router (running m0n0wall), that I have successfully installed a PPTP device (ppp0) on, this is working flawlessly (following this link) The thing is I want this box to route all it's internet traffic through the VPN tunnel (ppp0 device) but also being able to access the local LAN on 192.168.1.* subnet. I've succeeded a bit with this, but my problem right now is that I have port forwards (e.g. SSH) done in the m0n0wall pointing to this specific box which forces me to do "add routes" to all boxes that want to access this machine through this specific port. For instance a machine with ip xyz.xyz.xyz.xyz needs to have a static route setup in the routing table on the box to be able to access the box. This is the result of route -n xxx.xxx.137.2 192.168.1.1 255.255.255.255 UGH 0 0 0 eth0 xxx.xxx.137.2 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 yyy.yyy.0.0 192.168.1.1 255.255.0.0 UG 0 0 0 eth0 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0 Where xxx is the IPs provided from VPN server. yyy.yyy.0.0 is a net that i want to have access to the box, without this I can't access the box from outside the LAN (via port-forwards done in router software, m0n0wall) is there away round this ugly solution?

USB 3.0 ports backwards compatibility problems with 2.0 devices?

- by AaronLS

I see some info on the net that suggest that I should be able to get my USB 2.0 devices to work in 3.0 ports. I only have two 2.0 ports on my new computer, and six 3.0 ports. I have installed drives. There's two different drivers, I guess some of the ports are supported by the intel board and some supported by some other chipset on the motherboard. I however have yet to get any of the 3.0 ports to work, and my brother had had the same issue with his devices not working in 3.0 ports on his computer. So I am beginning to wonder if the backwards compatibility isn't reliable for some reason. Maybe manufacturers opting not to implement 2.0 support on the 3.0 ports. I understand that physically the wiring is there, but that is only half the story. Beyond my brother's and my own computers (different motherboards/everything), I have yet to see a 2.0 device work in a 3.0 port. Is there any reason for this apparent device incompatibility? I.e. looking for responses that would indicate what areas to explore for issues or if there is any known cases of manufacturers deviating from spec in hardware or drivers. I am aware it's "supposed" to work :) Update: Does this have any relation to "USB Legacy Support" options in the BIOS? There several options combinations of options with "USB Legacy Support" and "USB 3.0 Legacy Support" and the description for these is a bit confusing, sounds like a bad translation.

Windows XP - Power surge on hub port

- by Swift-Tuttle

Hi, Since last few weeks I constantly get this error, as status bar balloon: Power Surge on Hub Port - A USB device has exceeded the power limits of its hub port. Due to this now I am unable to access any USB devices properly, they get disconnected intermittently. I did quite a few things to resolve this problem, firstly obviously through the Windows help. I even tried all the things told on the Microsoft website(which essentially says is to check and update the driver) but in vain. One suggestion, I found when I google'd was to disable the USB2 controller through the Device Manager and since at every startup the System configuration comes up complaining that it has been changed etc.(On that same site it is mentioned to ignore this message.) But after everything I still cant solve this problem. Any help is much appreciated. The system is installed with Windows XP service Pack 3 and all the updates till last month. Please let me know if any other hardware info is required. **UPDATE** My laptop is about 5 years old now, its an HP with Celeron 1.4G processor. Windows XP SP3 installed. All latest windows updates installed. 2 USB ports available. BIOS is HP 68DTD ver F.0A Do I need to update my BIOS from somewhere ? or is this a hardware problem altogether?

Secure NAT setup with iptables

- by TheBigB

I have Debian running device that needs to act as an internet-gateway. On top of that I want to provide a firewall that not only blocks inbound traffic, but also outbound traffic. And I figured iptables should be able to do the job. The problem: I've configured NAT properly (I think?), but once I set the default policy to DROP and add rules to for instance allow HTTP traffic from inside the LAN, HTTP is not going through. So basically my rules don't seem to work. Below is the initialization script that I use for iptables. The device has two NICs, respectively eth0 (the WAN interface) and eth1 (the LAN interface). echo 1 > /proc/sys/net/ipv4/ip_forward # Flush tables iptables -F iptables -t nat -F # Set policies iptables -P INPUT DROP iptables -P OUTPUT DROP # NAT iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT # Allow outbound HTTP from LAN? iptables -A FORWARD -i eth1 -o eth0 -p tcp --dport 80 -j ACCEPT iptables -A OUTPUT -p tcp --dport 80 -j ACCEPT Can anyone shed some light on this?

Is it possible to command a common router without using the web interface?

- by MDeSchaepmeester

Some background The internet arrangement in my student home is really weird. There is one ethernet outlet and several wifi hotspots. Either way requires a login through a web site to get internet access. This is annoying as each device needs to login seperately and with a PS3 for example, it is impossible to get connected at all since the web login procedure doesn't work. Therefore I have installed a D-Link DIR-635 router which is connected to the ethernet outlet. It has DHCP enabled so it uses NAT, but whatever it is connected to also uses NAT and I've read this should not work. A fellow student tried it with an Apple Airport but that keeps giving errors related to NAT after NAT. Anyway my setup does work so bonus points if you can clarify this. I need to login to the web site I mentioned earlier with any device, after which all devices in my LAN have connectivity. This is great. Except... In short From time to time, I lose internet connectivity and my D-Link DIR-635 router needs to do a DHCP renew. I can do this via the web interface but my life would be easier if I could just run a cmd file which tells my router to do this without all the hassle. This would setup a connection to my router and execute the proper command. I have tried googling but couldn't find much helpful stuff.

Hard Reset USB in Ubuntu 10.04

- by Cory

I have a USB device (a modem) that is really finicky. Sometimes it works fine, but other times it refuses to connect. The only solution I have found to fix it once it gets into a bad state is to physically unplug the device and plug it back in. However, I don't always have physical access to the machine it is plugged in on, so I'm looking for a way to do this through the command line. This post suggests running: $ sudo modprobe -w -r usb_storage; sudo modprobe usb_storage However I get an "unknown option -w" output. This slightly modified command: $ sudo modprobe -r usb_storage Fails with the message FATAL: Module usb_storage is in use. If I try to kill -9 the processes marked [usb-storage] before running they refuse to die (I think because they are deeply tied to the kernel). Anyone know of a way to do this? NOTE: I cross-posted this on serverfault as I didn't know which was more appropriate. I will delete and/or link whichever one is answered first.

Boot stuck at blinking cursor before GRUB - only works via BIOS boot menu

- by delta1

I have a new box running Debian Squeeze. Grub is installed on /dev/sda, but when booting up I just get a blinking cursor, before the Grub menu. I can only boot to grub successfully when I choose boot options (during post) and select that specific drive! I have made sure the correct drive is set to boot first in the BIOS. So Grub works, but the system won't boot to that drive automatically? Any ideas on what could cause this? Drives sda/b/c are all 2TB (sda runs the system with b/c as raid device md0) with the following partitions: $ cat /proc/partitions major minor #blocks name 8 0 1953514584 sda 8 1 977 sda1 8 2 9765625 sda2 8 3 6445313 sda3 8 4 1937302627 sda4 8 32 1953514584 sdc 8 16 1953514584 sdb 9 0 1953513424 md0 but # fdisk -l /dev/sda gives WARNING: GPT (GUID Partition Table) detected on '/dev/sda'!

Did Adobe Photoshop just killed my Graphics Card for good?

- by user6004

I was working with Adobe Photoshop, just some regular work, when I came to edit a PSD file and change the text of some layer, when all of a sudden the PC froze. No mouse, screen is frozen, keyboard strokes aren't getting me anything, no Task Manager, nada. So I rebooted my PC, and then something quite terrifying appeared before my eyes. It was not the Checkdisk utility that was launched, that made me terrified (by the way, that reboot damaged the partition table of an external HDD that was connected at the time to my PC, but that's another story). It was the screen itself. Please have a look. So after Checkdisk finished and Windows loaded, I noticed that the resolution was not right. Instead of 1440x900 which I had set, it was 1280x1024. When I went to change it back, I had no option to change back to my old resolution, and has only 3 other general resolution properties, as if my Video Card (GeForce 8800 GTS btw) was not recognized. And what do you know, in the Device Manager it appeared with an exclamation mark. Inside the hardware, it said this: Windows has stopped this device because it has reported problems. (Code 43) Uninstalling the drivers, downloading the newest drivers from NVIDIA and installing them did not work. It always comes back to this. So, do you have any advice before I go out and buy a new graphics card? I thought this was the only option left, but maybe the experts at Super User can help me out. By the way, the dotted screen appears after every reboot, and I see the dots when the ASUS Motherboard screen shows up at boot. Thanks in advance.

Install Peppermint OS three on Asus EeePC

- by Kithoth

I just had a new Asus EeePC R051CX. Out of the box, the installed OS is Ubuntu 12.04 LTS, but I am trying to install Peppermint OS three (as single boot). Problem. Once on live CD (well, live USB stick...), I'm in trouble in both following situations: Try Peppermint OS Live In this case, the first thing I get is a message reading The system is running in low-graphics mode Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself. I can solely press "return" to accept, then I have a list of 4 options to answer the question "What would you like to do?". But I simply can't do anything at this moment, except switching to console mode or rebooting (keyboard / mouse controls don't allow me to do anything else). Install Peppermint OS Something I really don't understand... it launches the Ubuntu Recovery Media (which was already installed when I received the device)! Also, it says in the bottom ERROR: This recovery media only functions on Ubuntu systems. All I can do is quit (that is, reboot). One last important thing that comes to my mind: this stick worked just fine on the other computers I've tried it on. I really hope someone could bring me the light, a friend of mine told me how cool this OS is for EeePCs. Don't want to give up! Thanks. Edit I finally could install Peppermint, but not by understanding why I couldn't do it the logical way. Instead, I reinstalled Ubuntu myself (erasing the factory one). Then, I could simply boot on my live USB and perform a fresh install of Peppermint. So, I still don't know how and why the mentioned problem occurred.

How can I determine the IP addresses allocated by DHCP on a router that I'm connected to?

- by user234831

This "router" is not a typical situation. I'm using my phone as a hotspot and can only configure a select number of DHCP options. I can manage the limit on how many devices/clients can use my phone as a hotspot. I have to select from a radio-button list with the options: 2,3,4,5, or 8 I can specify the DHCP starting IP address. In this case, it begins at 192.168.6.106 When I'm connected via WIFI to my phone, an ipconfig /all command shows me that the default gateway is 192.168.6.1 and my IPv4 address is 192.168.1.148. I have the luxury of connecting another device to the phone and that device was assigned 192.168.1.121. I've tried connecting to 192.168.6.1, hoping for some sort of router setup page that I'm used to seeing, but there is no such thing or maybe it's just a matter of incompatable operating systems. In summary, the "router" (phone) has an IP address of 192.168.6.1 and a DHCP server that begins at 192.168.6.106 and allows up to 8 connections. Normally, I would assume a range of 192.168.6.106 - 192.168.6.113, but connected clients are showing otherwise. How can I figure out which IP addresses are set aside by DHCP for clients?

Suggestions for transitioning to new GW/private network

- by Quinten

I am replacing a private T1 link with a new firewall device with an ipsec tunnel for a branch office. I am trying to figure out the right way to transition folks at the new site over to the new connection, so that they default to using the much faster tunnel. Existing network: 192.168.254.0/24, gw 192.168.254.253 (Cisco router plugged in to private t1) Test network I have been using with ipsec tunnel: 192.168.1.0/24, gw 192.168.1.1 (pfsense fw plugged in to public internet), also plugged in to same switch as the old network. There are probably ~20-30 network devices in the existing subnet, about 5 with static IPs. The remote endpoint is already the firewall--I can't set up redundant links to the existing subnet. In other words, as soon as I change the tunnel configuration to point to 192.168.254.0/24, all devices in the existing subnet will stop working because they point to the wrong gateway. I'd like some ability to do this slowly--such that I can move over a few clients and verify the stability of the new link before moving critical services or less tolerant users over. What's the right way to do this? Change the netmask on all of the devices to /16, and update gateway to point to the new device? Could this cause any problems? Also, how should I handle DNS? The pfsense box is not aware of my Active Directory environment. But if I change DNS to use the local servers, it will result in a huge slowdown as DNS queries will still be routed over the private t1. I need some help coming up with a plan that's not too disruptive but will really let me thoroughly test the stability of the IPSEC tunnel before I make the final switch. The AD version is 2008R2, as are the servers. Workstations are mostly Windows XP SP3. I have not configured the 192.168.1.0/24 as a site in AD sites and services.

Putting and configuring grub on an external drive

- by HisDudeness

I want to put a bunch of minor emergency operating systems (such as GParted Live, DSL, Puppy Linux and so on) on a partitioned USB pen drive, with a dedicated grub boot loader on it, which I want to start when I select the drive in the BIOS to boot. The problem is: when writing grub boot options I must tell where kernel and initial ram files are located, but the USB drive can have different letters depending on when I did plug it in, if some others external drive were mounted. So, how can I write appropriate options which automatically refer to the drive grub is installed on without having to specify absolute paths, which might change (I mean, like (hd1,msdos1) ot /dev/sdb1)? And, while we are at it, can I have grub working on a device without an operating system on it to which it can refer? I mean, I want to address the command sudo grub-install /dev/sdb from the LMDE system I'm on right now, but I won't have LMDE on my pen drive. Is that a problem? And installing grub on another device, will I keep the grub I have right now on my HDD?

Ethernet cable unplugged after updating from windows 8.0 to 8.1

- by Pehmolelu

Yeah, so I went and updated my windows 8 pro to 8.1. Now everything else seems to work but the network. The Ethernet just says that Network cable is unplugged, even though it is plugged and I have tried different cord as well and I have tested that the router works. I have tried uninstalling the network drivers (Realtec PCIe GBE) and reinstall them with no success. After installing drivers the Device Management gives error for it "Device could not be started. Code 10" Before 8.1 update I had rt630x64.inf, after update it was netrt630x64.inf, and after installing the latest driver rt630x64.inf. With rt630x64.inf there isn't any error, but it's still not just working. New downloaded version: 8.020.0815.2013 (From Realtek website) The driver before: 8.1.510.2013 (After updating the windows to 8.1) I'm using Desktop PC, no VM. I dont have VirtualBox or Vmware installed. I have checked from BIOS that the card is enabled. I have booted in safe mode with network enabled. Says unplugged there as well. I have put the power off for few minutes and put back on, no effect. If anyone has any kind of suggestions, please tell.
