  • Built-in network card not working?

    - by Zeeshan
    Hi, I am new to Ubuntu. I have installed Ubuntu 9.04(Jaunty). After installation I found that network card is not wokring. And id doest not list in "System Preferenes Network Connections" So , i got another card from my friend and try to search on internat about my problem but still cant find solution. Some commands output is here which may be help to solve problem root@mzeeshan-desktop:/home/mzeeshan# uname -r 2.6.28-11-generic root@mzeeshan-desktop:/home/mzeeshan# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:02:44:4a:45:12 inet addr:192.168.5.37 Bcast:192.168.5.255 Mask:255.255.255.0 inet6 addr: fe80::202:44ff:fe4a:4512/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3774 errors:0 dropped:0 overruns:0 frame:0 TX packets:3611 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4307045 (4.3 MB) TX bytes:583067 (583.0 KB) Interrupt:22 Base address:0x1000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:240 (240.0 B) TX bytes:240 (240.0 B) pan0 Link encap:Ethernet HWaddr 5e:25:17:a1:18:ac BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) root@mzeeshan-desktop:/home/mzeeshan# lspci 00:00.0 Host bridge: Intel Corporation Device 0069 (rev 12) 00:01.0 PCI bridge: Intel Corporation Auburndale/Havendale PCI Express x16 Root Port (rev 12) 00:19.0 Ethernet controller: Intel Corporation Device 10f0 (rev 05) 00:1a.0 USB Controller: Intel Corporation Ibex Peak USB2 Enhanced Host Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation Ibex Peak PCI Express Root Port 1 (rev 05) 00:1c.4 PCI bridge: Intel Corporation Ibex Peak PCI Express Root Port 5 (rev 05) 00:1c.6 PCI bridge: Intel Corporation Ibex Peak PCI Express Root Port 7 (rev 05) 00:1c.7 PCI bridge: Intel Corporation Ibex Peak PCI Express Root Port 8 (rev 05) 00:1d.0 USB Controller: Intel Corporation Ibex Peak USB2 Enhanced Host Controller (rev 05) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev a5) 00:1f.0 ISA bridge: Intel Corporation Ibex Peak LPC Interface Controller (rev 05) 00:1f.2 IDE interface: Intel Corporation Ibex Peak 4 port SATA IDE Controller (rev 05) 00:1f.3 SMBus: Intel Corporation Ibex Peak SMBus Controller (rev 05) 00:1f.5 IDE interface: Intel Corporation Ibex Peak 2 port SATA IDE Controller (rev 05) 01:00.0 VGA compatible controller: nVidia Corporation GeForce 8400 GS (rev a1) 06:00.0 Multimedia audio controller: Creative Labs SB Live!

  • Can I make two wireless routers communicate using the wireless?

    - by Dana Robinson
    I want to make a setup like this: cable modem <-cable- wireless router 1 <-wireless- wireless router 2 in another room <-cables- PCs in another room Basically, I want to extend my network access across the house and then have a bunch of network jacks available for my office PCs. Right now, I have a cable modem going to a wireless router in one room and a PC with a wireless PCI card in it in the office on the other side of the house. I use internet connection sharing with the other PCs in the office. The problem is that ICS is flaky, especially when I switch to VPN on the Windows box to access files at work. I picked up a wireless USB adapter that I thought I could share among the PCs I work on but I'm not very happy with it so I'm going to return it (NDISwrapper support for it is poor). Is this possible? My wireless experience so far has been pretty straightforward so I have no idea what kind of hardware is available. I've looked at network extenders but those just look like repeaters for signal strength. I want wired network jacks in my office.

  • Linux wireless disconnect every 20 minutes

    - by james
    My laptop uses CentOS 6.3 with kernel 2.6.32-279.el6.x86_64. My wireless adaptor is Intel Corporation Centrino Wireless-N 1000. My wireless connection always get off after about 20 minutes. The network applet shows the connection is still on with good signal strength, but I just cannot load any web pages even the configuration page of the wireless router. The problem will continue until I disable and reconnect the wireless. Other devices like my cell phone uses the same wireless network without the problem. Even yesterday I'm using the same laptop with Fedora 17 without this problem. I also searched the internet and someone said running services NetworkManager and network simultaneously may be a problem. But I cannot stop any one of them because: if I stop network and start NetworkManager, the network service will start automatically; if I stop NetworkManager and run network, it says "Device does not seem to be present, delaying initialization." when trying to bringing on the wireless. What shall I do to get rid of the problem? Thank you very much!

  • What's going on with my wireless?

    - by Mark Scott
    The WiFi on my Acer laptop (it's a 3810TZ, with Intel Corporation Centrino Wireless-N 1000) works flawlessly on Ubuntu 11.04. On 11.10, it's continually up and down, and it fills the system log with messages such as those below. What is going on? It seems to be unable to decide which regulatory domain it's in. Despite the system configuration being quite clearly set to UK it persists in configuring itself as though it was opeating in Taiwan!

  • WIfi Problems Ubuntu 13.10

    - by user289429
    i've been searching the forums for two days now but none of the answers seems to work for me. I have an acer extensa 5630 which has an Intel WIfi 5100. But even when i am right next to my router i cannot detect the wireless network. The weird thing is, that when i create a hotspot from my mobile phone it automatically detects it and connects to it.I think i do have the correct drivers installed. Thanks

  • Windows 7 Machine Makes Router Drop -All- Wireless Connections

    - by Hammer Bro.
    Some background: My home network consists of my Desktop, a two-month old Windows 7 (x64) machine which is online most frequently (N-spec), as well as three other Windows XP laptops (all G) that only connect every now and then (one for work, one for Netflix, and the other for infrequent regular laptop uses). I used to have a Belkin F5D8236-4 wireless router, and everything worked great. A week ago, however, I found out that the Belkin absolutely in no way would establish a VPN connection, something that has become important for work. So I bought a Netgear WNR3500v2/U/L. The wireless was acting a little sketchy at first for just the Windows 7 machine, but I thought it had something to do with 802.11N and I was in a hurry so I just fished up an ethernet cable and disabled the computer's wireless. It has now become apparent, though, that whenever the Windows 7 machine is connected to the router, all wireless connections become unstable. I was using my work laptop for a solid six hours today with no trouble, having multiple SSH connections open over VPN and streaming internet radio in the background. Then, within two minutes of turning on this Windows 7 box, I had lost all connectivity over the wireless. And I was two feet away from the router. The same sort of thing happens on all of the other laptops -- Netflix can be playing stuff all weekend, but if I come up here and do things on this (W7) computer, the streaming will be dead within ten minutes. So here are my basic observations: If the Windows 7 machine is off, then all connections will have a Signal Strength of Very Good or Excellent and a Speed of 48-54 Mbps for an indefinite amount of time. Shortly after the Windows 7 machine is turned on, all wireless connections will experience a consistent decline in Speed down to 1.0 Mbps, eventually losing their connection entirely. These machines will continue to maintain 70% signal strength, as observed by themselves and router. Once dropped, a wireless connection will have difficulty reconnecting. And, if a connection manages to become established, it will quickly drop off again. The Windows 7 machine itself will continue to function just fine if it's using a wired connection, although it will experience these same issues over the wireless. All of the drivers and firmwares are up to date, and this happened both with the stock Netgear firmware as well as the (current) DD-WRT. What I've tried: Making sure each computer is being assigned a distinct IP. (They are.) Disabling UPnP and Stateful Packet Inspection on the router. Disabling Network Sharing, SSDP Discovery, TCP/IP NetBios Helper and Computer Browser services on the Windows 7 machine. Disabling QoS Packet Scheduler, IPv6, and Link Layer Topology Discovery options on my ethernet controller (leaving only Client for Microsoft Networks, File and Printer Sharing, and IPv4 enabled). What I think: It seems awfully similar to the problems discussed in detail at http://social.msdn.microsoft.com/Forums/en/wsk/thread/1064e397-9d9b-4ae2-bc8e-c8798e591915 (which was both the most relevant and concrete information I could dig up on the internet). I still think that something the Windows 7 IP stack (or just Operating System itself) is doing is giving the router fits. However, I could be wrong, because I have two key differences. One is that most instances of this problem are reported as the entire router dying or restarting, and mine still works just fine over the wired connection. The other is that it's a new router, tested with both the factory firmware and the (I assume) well-maintained DD-WRT project. Even if Windows 7 is still secretly sending IPv6 packets or the TCP Window Scaling implementation that I hear Vista caused some trouble with (even though I've tried my best to disable anything fancy), this router should support those functions. I don't want to get a new or a replacement router unless someone can convince me that this is a defective unit. But the problem seems too specific and predictable by my instincts to be a hardware hiccup. And I don't want to deal with the inevitable problems that always seem to take half a day to resolve when getting a new router, since I'm frantically working (including tomorrow) to complete a project by next week's deadline. Plus, I think in the worst case scenario, I could keep this router connected directly to the modem, disable its wireless entirely, and connect the old Belkin to it directly. That should allow me to still use VPN (although I'll have to plug my work laptop directly into that router), and then maintain wireless connections for all of the other computers. But that feels so wrong to me. Anyone have any ideas what the cause and possible solution could be? Clarifications: The Windows 7 machine is directly connected via an ethernet cable to the router for everything above. But while it is online, all other computers' wireless connections become unusable. It is not an issue of signal strength or interference -- no other devices within scanning range are using Channel 1, and the problem will affect computers that are literally feet away from the router with 95% signal strength.

    Note: I accidentally originally posted this question over at SuperUser, and I still think the issue is caused by some low-level networking practice of Windows 7, but I think the expertise here would be more apt to figuring it out. Apologies for the cross-post.

The other is that it's a new router, tested with both the factory firmware and the (I assume) well-maintained DD-WRT project. Even if Windows 7 is still secretly sending IPv6 packets or the TCP Window Scaling implementation that I hear Vista caused some trouble with (even though I've tried my best to disable anything fancy), this router should support those functions. I don't want to get a new or a replacement router unless someone can convince me that this is a defective unit. But the problem seems too specific and predictable by my instincts to be a hardware hiccup. And I don't want to deal with the inevitable problems that always seem to take half a day to resolve when getting a new router, since I'm frantically working (including tomorrow) to complete a project by next week's deadline. Plus, I think in the worst case scenario, I could keep this router connected directly to the modem, disable its wireless entirely, and connect the old Belkin to it directly. That should allow me to still use VPN (although I'll have to plug my work laptop directly into that router), and then maintain wireless connections for all of the other computers. But that feels so wrong to me. Anyone have any ideas what the cause and possible solution could be? Clarifications: The Windows 7 machine is directly connected via an ethernet cable to the router for everything above. But while it is online, all other computers' wireless connections become unusable. It is not an issue of signal strength or interference -- no other devices within scanning range are using Channel 1, and the problem will affect computers that are literally feet away from the router with 95% signal strength.

  • Are Intel HD 4000 graphics supported on Ubuntu 10.04 LTS?

    - by user1118764
    I have an intel Core i7-3700 system with Intel HD 4000 integrated graphics with a dual monitor setup (1 connected via VGA, the other via DVI) on Ubuntu 10.04 LTS 64bit. I'm trying to get my monitors correctly detected. Right now, in only 1 unknown monitor is detected with a max resolution of 1280x1024, which is lower than my main monitor connected to DVI. Also, the desktop is mirrored rather than extended. I've previously managed to get a Core i5-2400 system with Intel HD 3000 integrated graphics with the same dual monitor setup and Ubuntu 10.04 LTS 64bit to work using the glasen ppa drivers, but this time, after installing them following the instructions How do I install the Intel HD 3000 video driver? but it doesn't seem to work. Does the Intel HD 4000 require a different driver from the 3000? If so, where can I get it?

  • How can fix HDMI HDTV overscan when I my TV has no aspect ratio setting?

    - by Colin Dean
    I have a 32" Vizio HDTV. It's a few years old, but running well. I just connected a new nettop to it using HDMI out. It's the Intel 3x00 graphics chipset. I'm seeing overscan, where the resolution in Ubuntu is set to 1280x720, but the TV itself is 1366x768. When I go into the Monitors control applet, I cannot change the resolution to anything other than the current or 640x480. A user had a similar overscan problem, but fixed the overscan by adjusting his TV's aspect ratio settings. I do not have that luxury. Is there a way I can do this without having to delve into xorg.conf or other command-line craziness? I'm more than comfortable doing so, but there must be a cleaner way. I'm running Ubuntu Natty, keeping up with updates and such.

Any reasons why, thanks.

  • Trouble with wireless driver on a Dell Latitude D830

    - by Kevin
    After uninstalling Dell's wireless utility I get a new hardware found dialog that can not find any driver for my wifi card on it's own. I'm running Windows XP Professional Service Pack 3, and I would like to use the default wifi handler since dell's utility does not work with my company's wireless switch. I did try downloading the recommend driver from the dell support site Network Adapter 2 Model Intel(R) PRO/Wireless 3945ABG Network Connection Description [12] Intel(R) PRO/Wireless 3945ABG Network Connection Status Connected

  • Set default wireless adapter

    - by Evan Kroske
    I just acquired a Wi-Fire long-range wi-fi adapter, and I would like to test it with my Ubuntu desktop computer. However, my machine defaults to using a built-in wireless card. How can I set my new wireless adapter as the default wireless connection? How can I disable my internal wireless card (without opening my computer case)?

  • DLINK WBR-1310B Wireless Router seems to hang...

    - by Ira Baxter
    I have a brand new DLINK-1310B Wireless Router (box never before opened, although I bought it at the neighborhood computer junk store). I am using it at home (and in fact am using it at this instant from a wireless laptop). When operative, I can ping it at 192.168.0.1, and I can log into it from the PC attached to it by LAN and from the wireless PC at //192.168.0.1. In the course of the day since I've installed, it seems to have locked up 3 times. Each time the symptoms are my web browser (or other IP service, e.g., POP3) stops with a "No internet connection" error. Attempts to contact the router via 192.168.0.1 get no reaction, from either the wireless laptop or from the hardwired PC sitting next to it. It doesn't respond to pings to that address either. Power cycling the router fixes it. I've seen discussion in other questions about aging cheap electronics. Its too new to be aged. Anybody else seen this behavior with a DLINK-1310? Or do I just need to exchange it for another and try again? (I hate rolling dice, I bought the DLINK because a previous Linksys died of apparant heating problems, how many do I have to cycle through before I get something that works and is long-term stable?). Remarkably, nobody talks about how much software is in a router. Is the stuff just buggy? EDIT: Happened again, while I was working on the wireless Vista laptop. (Seems like once an hour?) I was a little more careful this time. The wireless laptop can ping it. It can't get the login screen. I visited the LAN-connected PC (takes me a minute to walk from the laptop to the PC at the other end of the house), and attempted to visit a random web page. Surprise, that worked! And, now, after a minute walking back to the laptop, I can reconnect the wireless laptop, and get to the login page from it. Strange the time/date has been reset back to 2002. (I'll swear I set it and saved the system configuration after updating the firmware; it made me redo every other bit of reconfiguration again). Is there something funny about wireless leases expiring? The router says the leases it is handing out are good for 180 minutes, and the delay-to-inaccessible was only about an hour. The DSL connection seems to have a 10 minute lease.

  • How to get wireless working (properly) with Sitecom Wireless USB micro adapter 300N on Windows 7?

    - by Timo
    The question says it all, but more detail follows ;) I've got a new computer that runs Windows 7 64-bits (Home Edition) and I'd like to connect it to my wireless home network (Sitecom wireless gigabit router 300N wl-352 v1 002) with a Sitecom wireless USB micro adaptapter 300 wl-352 V2 001. After installing the router (i.e. connected to the modem and power) and ensuring that wireless is indeed enabled, I've installed the driver of the USB adapter on the new computer described above. After the installation (drivers and utility on CD) completes successfull I rebooted my computer and inserted the USB adapter. After discovering the right network and connecting to it using the network key, a connection is succesfully made. (Using the Sitecom 300N USB Wireless LAN utility). In the LAN utility I can see that the signal strength is approximately 50% and connection quality is approximately 80%. Judging from these numbers I assumed that all was fine and started to use the connection (reading news on nu.nl, a dutch news site), but noticed that the connection was lost several times in a very short time span, but each time the connections was resumed, resulting in the 50/80 percent numbers described above. However, the website was not loaded completely and often a timeout would be reported. When inspecting the drivers through Device Management (Windows' Apparaatbeheer in dutch) there were no errors/warnings; everything seemed to be in order. In an attempt to solve this, I downloaded the latest drivers for the USB adapter, but the problems remained. Finally I tried to connect the computer with a Siemens Gigaset USB Adapter 108. This process was a troublesome since I had to download a driver (from the site above) and tell Windows (7) to use the Windows Vista driver when installing the new hardware, since there is (was) no Windows 7 driver available. This resulted in a usable connection, although not very stable when reconfiguring the router. Which took the form of selecting a different wireless channel on the router, even using the Sitecom utility mentioned above to check if there were other networks communicating on that channel (and thus picking a channel that was not used by other networks). Again no result when changing back to the Sitecom USB adapter. Note that this means (I think) that I could use the internet connection with the Siemens adapter, meaning the problem was not in the router. So: How to get wireless working (properly) with Sitecom Wireless USB micro adapter 300N on Windows 7? PS Sorry, but should be able to post one link, while I had links in place for the USB adapter, router and the siemens adapter in place as well, but I'm not (yet) allowed to post these... (The site says I can post one link, but only when no links are present will it allow me to post the question...)

  • Is ThinkPad X61T SD card slot SDXC compatible?

    - by trismarck
    I have a Thinkpad X61T 7763 tablet and I was planning to buy a 64GB card for the SD card slot. The 64GB card supports the new SDXC standard and I'm not sure if the SD card driver / hardware can handle that. So far, I've successfully used 8GB cards in the slot, but they were SDHC ones. Thinkpad manuals don't give the answer. I wonder if anyone tried this configuration already and what was the outcome.

  • Graphics card artifacting

    - by White Phoenix
    This is my current build: EVGA X58 (first generation) motherboard Intel i7 965 @ stock clocks 3x 2GB DDR3-1600 Corsair RAM at stock timings and voltages Corsair AX750 80 Plus Gold PSU 1 Optical Drive 1 Seagate 7200.10 500 GB drive 2x Western Digital Caviar Black 1 TB drives OCZ Vertex 1 60 GB EVGA GTX 460 Antec 1200 case HT-Omega Striker 7.1 Sound Card Windows 7 32-bit Professional (PAE Enabled) My graphics card started artifacting while I was playing a game. It artifacted, the display blinked, then I got an NVIDIA driver has crashed and recovered message. Kept going, more artifacts, another crash, but this time my display blanked out and I couldn't do anything. Restarted my computer - artifacting is in the BIOS - got to Windows 7 but it BSOD'd before I could even log in. I restarted the computer again - artifacts cleared themselves out and I managed to get to Win7, but it soon started blinking in and out and artifacting again. Checked the card temps and they're well within range. (50 idle, 70 full load) The ambient temperature here is about 80-85F with high humidity. Tried Safe Mode and it still froze up/BSOD'd. Already tried the following to fix this problem: - Reseat the graphics card and swapped in a different slot. - Removed cover on card and sprayed with compressed air to clean it out. - Swapped around memory and/or went with only using one stick at a time. - Underclocked card I called EVGA Tech Support and they said that the voltage on the 12V rail of my Corsair AX750 PSU was on the high end of the "acceptable" range (12.4V, highest within acceptable range is 12.6V - optimal is obviously 12V). They gave me an RMA number anyway, but I want to get a second opinion from you all before I send this thing off, as shipping from where I live to EVGA is kind of pricey. This PSU is only 6 months old. So that I don't have to play RMA tag, which case would be most likely? I'm strapped for cash at the moment so I want to reduce the amount of RMAs I have to do since shipping is expensive here. Is there any surefire way to test to see if it's really the graphics card or the PSU? I tried unplugging any devices that were connected to the 12V rail (except for my SSD and graphics card) as I do have 3 mechanical hard drives, but the voltage for that rail didn't drop (it remained at 12.4V). I'm fairly sure it isn't the drivers since I'm getting the artifacting at the BIOS too. Right now I'm back in Windows 7 but I don't know for how long until it messes up again. Any ideas?

  • VM using a secondary graphic card

    - by Arthur
    Hi everyone, at the moment i have a dual monitor setup on my main PCIe gfx card. I know that on windows it is almost impossible to have a second card (eg no thrills PCI card) running without having an SLI motherboard because of a driver issue. Well this was my conclusion after many weeks of research. I was thinking...is it possible to use a VM in order to utilize the secondary card as the default video output to feed another monitor? let me know if you want me to clarify Thanks :)

  • All wireless networks suddenly disappear every once in a while

    - by snakile
    Lately, about every 15-60 minutes, my wireless internet connection disappears. When it does I can't find any other wireless network, though such networks exist. Only after rebooting the system, it goes back to normal and finds wireless networks, but only for a while. 15-60 minutes later it's disconnected again, not finding any wireless network. I'm using Windows 7 on Lenovo Thinkpad X201s. What could it be?

  • Does this video card support sound?

    - by Macros
    Probably a rookie question but here goes...I am looking to buy a new video card for a few year old PC which will be used as a media centre. The card I am looking at is this one http://www.ebuyer.com/product/173708, with the main aim being to play blu-ray films. In the product description it states that the card has 7.1 audio channel support, does this mean it will play the sound from the blu-ray through the HDMI, or do I need a separate sound card?

We have 3 blocks between 200 mtrs, We like to connect all the laptops Lan Card directly with required Access-point. What should we do to achieve this, right now we are not getting the full strength signal, when we cross the 80 mtrs. So please suggest me proper configuration for implementing this TP-Link access point. Thanks PPS

  • Getting VMWare ESXi 5.0.0 with RAID using the Intel X79 chipset to work

    - by Deleted
    I have bought a new server where I use the motherboard ASUS P9X79 WS X79 S-2011 ATX. It will be used for virtualization, preferably using VMware vSphere Hypervisor™ (ESXi) if I can get the RAID on my motherboard working with VMWare (it does not detect it). The motherboard has the Intel® X79 chipset, which for RAID controller means vendor ID 8086 (Intel) and model ID 2826. When I boot the ESXi 5.0.0 installation media from my flash drive I can not see drives in the RAID5 set I created. Questions: Is there a VIB file for the RAID controller I can use? I have found one article at http://www.intel.com/support/motherboards/server/sb/CS-033313.htm on getting RAID to work with some Intel controllers, it lists 9 integrated RAID modules it is comptabile with. However, there is no mention of the X79 chipset.
