  • lenovo x1 carbon windows 8 frequent wifi disconnect issue

    - by hIpPy
    I'm having frequent wifi disconnects on my Lenovo X1 Carbon Touch laptop. I got this laptop 2 months back and it has been happening ever since about 3-5 times a day and 10 times a week on average. I've Frontier Fios internet. Power connected or not does not matter. Once I get disconnected, I try below to connect again in that order: turn Airplane mode on and off, troubleshoot network problems windows troubleshooter), restart the laptop I'd find that the WiFi adapter would get disabled and sometimes windows troubleshooting would help but more than often I'd end up restarting the laptop. A week back, I upgraded my wifi network adapter drivers (now Intel, version 15.5.6.48, 10/3/2012). I still get disconnected frequently but turning Airplane mode on and off gets me connected again. So the driver update did help. Windows 8 is updated. None of the other devices (nexus, iphone phones, nexus7, ipad tablets) would have wifi issues when my laptop would get disconnected. config: Intel(R) Centrino(R) Advanced-N 6205 (WiFi network adapter) Microsoft Windows 8 Pro Microsoft Windows [Version 6.2.9200] x64-based PC LENOVO System Model: 3443CTO X1 Carbon Touch I recently noticed this log message When I got disconnected in event viewer: Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x[XXXXXXXXXXXX]. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server. Any idea?

  • How to troubleshoot Linksys E4200 Remote Management

    - by Jordan
    My Linksys E4200 is configured for Remote Management, but the router is not accepting the connections. Here's the configuration under Administration Management Remote Management Access: Remote Management: Enabled Access via: HTTP Remote Upgrade: Disabled Allowed Remote IP Address: Any IP Address Remote Management Port: 8080 The router is setup to use 192.168.10.41 as its static Internet IP address, and 192.168.35.1 as its LAN IP address. I can access the router just fine via its LAN IP address, but I can't make a connection using http://192.168.10.41:8080. I've tried variations of the settings above (enabled HTTPS, enabled Remote Upgrade, set an IP range of 192.168.10.1-254) but nothing has worked yet. Hoping someone can at least point me in the right direction. Thanks. Update: To clarify, I have a wired router that connects straight to the T1 modem. It's configured to use 192.168.10.1-254 as its internal LAN range. The E4200 wireless router in question is on that LAN using 192.168.10.41 as its WAN IP address. The E4200's internal LAN range is 192.168.35.1-254. I'm not trying to access the E4200 from the Internet, I'm just trying to access it from its WAN IP address. Thanks.

  • Windows 7 Media Center: sometimes no sound on a TV channel

    - by torbengb
    Problem Sometimes, recorded TV shows have no sound. This is of course very annoying because the recorded show is worthless. Also, when switching channels while watching live TV, sometimes a channel has no sound. This is always solved by switching channel again and then back (most often, once will do the trick). Media Center doesn't do this trick by itself when recording of course, so that's the bigger issue - but the cause is certainly the same. Details The computer is running a newly installed Windows 7 and Windows Media Center. It has 2 different tuner-cards installed. Both are installed with signed and up-to-date Win7 drivers and appear OK in Device Manager. Both tuners get the same antenna signal, from a split cable from the wall. The cable delivers analog cable TV (40+ channels) and digital cable TV (4 channels) at the same time. Both tuners have been configured to receive both analog and digital channels. This only happens with analog channels. How can I fix the no-sound problem? Update: I've now spent some time with the computer to try and pinpoint the problem, but I've had little success so far: I flipped through the channels until one didn't have sound, then I disconnected the antenna cable from one of the tuners. It was the right one because then the video also went away. I flipped lots more channels to see if the other card also would come up mute once but I never had a channel without sound. It might still be possible, I don't know. Then I disconnected the "good" tuner and connected the "bad" tuner and again flipped lots of channels but again I never had a channel without sound. It seems to me that the problem is erratic. It happens on any channel, and I haven't ruled out yet that it only happens on one tuner.

  • 412 Precodition Failed error only occurs on certain networks

    - by Andy
    One of my favorite websites: http://jessiejofficial.com (yes, I'm a Jessie J Fan :')) has recently started displaying the error message "412 Precondition Failed" whenever I visit it from my home network, even when I use Tor Browser. At first I thought that this was an issue with the whole website, however I have contacted the web developer and he has said that they has been plenty of hits within the last 48 hours. Plus, I discovered tonight that I can access the website from my phone, through the mobile network. So it appears to just be my network as all of the devices in my house connected to the WiFi display the same error when I try to visit any page of the site. However there have been no changes that we are aware of or are noticeable to our network since the website was accessible, and I have just heard that another person in a different part of the country is experiencing the same difficulties also. Any help/advice/suggestions would be appreciated greatly Update: When trying to ping 'jessiejofficial.com' in Windows command prompt the request times out on all four attempts, on any computer connected to the wireless network. I can now also confirm that the same thing occurs on my MacBook Pro.

  • Strange WiFi problem - network is "not connected" but works

    - by GalacticCowboy
    Background I'm using a Windows XP tablet PC connected to my home network. I do broadcast the SSID, but otherwise the wireless network is locked down as tight as I can make it - WPA2 with a strong key, MAC filtering, etc. I've had this computer for about 4 years and the router for about 6 months. Before that, the previous router was set up in the same way, and I've never had any particular problems. Problem This morning - as I type this, as a matter of fact - Windows is reporting that none of my network connections are connected. Yet somehow my Internet connectivity still works! ipconfig reports a valid IP address, domain, etc., even though Windows apparently doesn't know about it. I tried repairing the connection and it had no effect - the repair eventually timed out. I'm pretty sure that I could reboot the computer and/or the router, etc. and it would fix the problem. However, I'm more interested in knowing if any of you have ever seen anything like this, and what might have caused it? Since it works I'm not inclined to mess with it too much. My concern is that it's a precursor to bigger problems.

  • Why does my computer not always automatically request a new DHCP lease when switching networks?

    - by KingJ
    I've noticed an interesting problem recently where my laptop will not automatically refresh my DHCP lease when changing between wireless networks. Instead, it will attempt to use the existing lease for the new network. Of course, since each network has different settings any connections will fail when using the old lease. While Windows will eventually request a new DHCP lease, it's often much faster for me to release the old lease and request a new, correct, lease. It puzzles me as to why this is not automatically done when associating to the network? One possible cause is that the laptop is put to sleep while connected to one network, then woken when in range of the other network. Nevertheless, I would expect that the lease would be renewed when the laptop associates to the other network rather than attempting to use the old lease. It should be noted that the two networks are completely different, both in terms of size, number of APs, network settings, SSIDs etc. One network is my home network and the other one is the campus-wide network at my University.

  • MacMini transmit rate stuck at 11, every other device can connect at full 54Mbit/s?

    - by chum of chance
    I have a MacMini circa 2007 that's getting very low transmit rates via wifi, 8-11. I have other devices that are getting full 54, including a MacBook Air. With everything else off, the MacMini doesn't want to seem to go any faster. Since it has been previously connected to ethernet its entire life, I was wondering if there were some settings I can change to speed up the connection. Option-clicking the network icon gives this read out: PHY Mode: 802.11g Channel: 1 (2.4 Ghz) Security: WPA2 Personal RSSI: -73 Transmit Rate: 11 My new MacBook Air has the following readout: PHY Mode: 802.11n Channel: 1 (2.4 Ghz) Security: WPA2 Personal RSSI: -66 Transmit Rate: 79 Both have full bars and the wireless router is in the same room to eliminate any obstructions from the equation. Could the MacMini be connecting at an older protocol, like 802.11b and be reporting erroneously that it is connected at 802.11g? This would explain why I haven't seen a transmit rate above 11. Any further trouble shooting I can try before buying a new USB 802.11n device? The WiFi router is a DLink DIR-615. I can see other devices, and none, even the other g connected devices, are getting below 30-40 MBit/s. What's going on here?

  • Windows Update broke Wirless driver - Can't get it working again

    - by private_meta
    I naively installed a driver update incoming from Windows Updates yesterday. That caused my Wifi on my Notebook (HP ELitebook 2740p) to break. The network is working as I tried it with my other mobile devices. When installing said driver, it told me that the installation failed. I tried to do a system restore, which did not help getting wifi connectivity back. The device said it was working, but did not get any wifi connection and did not discover any networks. What I tried next was to uninstall the device from my Device Manager and install either the current drivers found through windows, then I tried the same with the current drivers on the HP driver page. both of those attempts failed. It always tells me that installation failed when I uninstall and reinstall drivers. If I try to update the broken driver via internet, it tells me it is up to date, and in the device manager it still views as broken. Next, I 'played' around a bit and reinstalled drivers, and I managed to install drivers from 2012, and when trying to update drivers manually and picking drivers that match the device, it lets me choose between drivers from 2010 and 2014. 2014 would be the current one, picking the 2010 driver leads to the driver being accepted. However, no wireless network can be found. I'm pretty much out of ideas by now, short of reinstalling. The only option I can still think of was that the device broke at the exact moment I installed the new windows driver, but I find that a bit unlikely. Any help would be appreciated fixing this issue.

  • How to boost playback volume in real time on media recorded with a very low volume.

    - by L Marksman
    I have never heard a satisfactory answer to this often misunderstood question, let me explain. Lets say I have a sound card and earphones/speakers that can play back audio loud enough in most cases. This is great but the problem is that you always find people who do not know how to record audio, from Youtube video's to music. So now you end up with a audio playback that only uses 10% or less of the capacity of your sound hardware, in vista/win 7 you will see this frequently in the mixer with the volume pushed up to max but the green sound level only goes up a millimeter or two. I am looking for (preferably free) software or a method to boost the sound level of any audio from any source in real time to use more of my hardware capacity similar to what VLC media player can do. Oh and please, do not tell me it is impossible. I am not trying to boost the volume past what my hardware is capable of, I am just trying to use my hardware's full capacity. Also please do not tell met to buy new hardware, I know I can use hardware amplification, I don't want to (like many others) spend money on a simple little problem like this. Thanks!

  • Dual Monitor/Xinerama not working; cannot even detect on-board graphic card

    - by Steven H
    I have Kubuntu 12.04 and two identical VGA monitors. One I plugged via DVI-VGA adapter into the DVI port of my discrete AMD Radeon HD 6670, the other into the VGA port of my on-board graphic card (Radeon HD 6410D). After installing Kubuntu I got a black screen, so I booted with nomodeset and installed AMD's catalyst drivers but only the monitor plugged into the discrete graphic card worked. Using lspci I saw that the on-board graphics was not listed. Then I found in the BIOS settings the options "Surround View" and "Onboard Dual Link DVI" both disabled. After enabling both, the on-board graphics card shows up in lspci but in amdcccle, it only shows as [Uknown display]Uknown adapter. When I try to enable xinerama, I get a black screen after rebooting on both monitors. I tried several options and hints from the web but nothing worked so far. I also reinstalled the AMD drivers several times. What should I do?

  • What video graphic card would permit ubuntu's standard driver to work well?

    - by Rick
    I installed ubuntu 12.04. All seemed well until I installed the nvidia driver. Then crashola! This situation is untenable. It seems I cannot trust nvidia, and it seems that I cannot rely on ubuntu gurus to test 3rd party drivers. So, apparently some video card manufacturers do not care enough about the linux market to test their drivers, or are there too many 3rd party video cards so that ubuntu folks do not test any 3rd party video drivers? Hence the question: What video graphic card would permit me to use ubuntu's standard driver so that I do not have to rely on nvidia's or any other 3rd-party driver? Perhaps I could then install THAT card and have things work? The ubuntu standard driver actually worked prior to installing the nvidia driver, but not well, and that was because the display flickered, and flickering gives me a headache.
