Ubuntu Networking :: Wireless Stopped Working On Thinkpad X201 (Intel Centrino 1000 N)?
Feb 18, 2011
I have Ubuntu 10.10 on a thinkpad X201. Wireless was working, but has stopped. It still works in windows, so it is not a hardware problem. iwlist wlan0 scan sees the available networks, but I cannot associate with any of them, including my own.
Last night was my first attempt to connect to a secured network, and nm-applet failed to make the connection even after entering the WEP encryption key and SSID. By turning networking off in nm-applet I was able to manually bring up the connection by editing /etc/network/interfaces and using ifup wlan0. (nm-applet seemed to be interfering as long as networking was turned on there.) Wireless was working perfectly until I rebooted. Now I can't get it to work at all. (There were some partially completed security updates which completed when I rebooted. I hope this wasn't the cause of the breakdown.)I notice that wpa_supplicant is always running. I tried killing it in case it might be interfering with the connection process, but something keeps restarting it.

I have a new Thinkpad t510 laptop with an intel centrino wireless N card (no bluetooth). I installed ubuntu a couple weeks ago after I got another hard drive in the expansion bay. I have the drive partitioned into two sections, 250gb for file storage, and 250gb for the linux OS. Currently no other OS is installed on the other harddrive.
I have had everything perfect for the past couple weeks, but once i installed some updates today, my wireless fails to work now. Just some general info that you might ask me, lspci | grep Network, returns
00:19.0 Ethernet controller: Intel Corporation 82577LM Gigabit Network Connection (rev 06) 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 Furthermore, on the top right of my screen, my wireless is grey'd out and says no network devices available on hover.

Im trying to connect to my college wireless network. I have looked a thinkwiki and no one has posted any bugs. Any ideas on getting it working again?

I'm releaving a HP Probook 4710S from it's native Vista) First of all let me say I'm happy because CentOs 5.6 handles it's Ati Radeon graphic flawlessly, unlike other Distro's I tried on this type of machine. So thumbs up for CentOs! But now I've come to a stop on the wireless card.

My wireless card is:
Code:
03:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 1000 [8086:0083]
On Fedora 15, when I boot kernel 2.6.40, my laptop is unable to connect to my wireless-G AP. dmesg shows the following:
Code:
[ 43.866090] wlan0: direct probe to 00:27:19:14:c2:ca (try 1/3)
[Code].....
It works fine, however, when I boot using kernel 2.6.38 (from which I am posting) and in Windows. Also, I found some emails from the linux-wireless mailing list which appear to be talking about the same problem.
The system is fully updated. I've tried the 11n_disable=1 hint I came across on the ThinkPad wiki, but it didn't help. (I'm on an Asus K42Ja, in case it's relevant)
Although I'm fine with staying at 2.6.38 for now, are there workarounds/fixes for this?

To make Intel Centrino Ultimate-N 6300 wireless card work on ubuntu, you just need to download the firmware from here decompress it and copy the ucode in /lib/firmware. This works in jaunty. My laptop is a HP Elitebook 8440p.

I'm new to linux. I've just installed Ubuntu 11.04. It has all been going ok, but the wireless just stopped working all of a sudden. The indicator light turned off and when I tried to turn it back on (Fn+F2) nothing happens. Sometimes, when I restart the computer, the wireless might work; but if the signal is lost the LED on my laptop turns off and I cannot reconnect. Also, in these strange cases that the wireless works when I restart I can manually turn it off (Fn+F2), but nothing happens when I try to switch it back on.
In the menu on the upper right corner I see 'Enable Networking' is checked, but 'Enable Wireless' cannot be modified.
I have a Dell Inspiron 6400 and the wireless device is an Intel Pro/Wireless 3945ABG.
I have tried to follow some of the threads on this forum on similar cases, but the ones that were comprehensible to me did not work (or I actually might not have understood them either). code...

I've got a Dell precision with Kubuntu 9.10. Wifi worked fine on that machine for months, but stopped working last week. I don't know what happened, but I recently did an "apt-get dist-upgrade". That might have something to do with it.
When I boot in Windows, wifi works fine.

My wireless worked out of the box for the past few months. When I was running low on battery recently, I put the laptop to sleep. When I woke it up, there was a black screen with a flashing underscore. I pressed a bunch of buttons but nothing happened. Then suddenly it said something about a wireless hardware error and I did a hard reset by holding down the power button. When I turned the computer back on, wireless was greyed out. There's no hardware switch to enable and disable wireless and the software switch had no effect. I tried echoing into the 'state' of the adapter but it didn't let me. When I tried sudo ifconfig wlan0 up it gave me the following error:
Code:
SIOCSIFFLAGS: Unknown error 132

I've had recurring problems with Ubuntu wifi on my Thinkpad before. Usually powering down and toggling the physical wifi switch off, then toggling wifi on again after the system has booted would solve the problem. This time that isn't working. Wireless is completely absent from the network-manager applet. Wireless works for me 99% of the time for me, but every few months will "disappear" for some reason. Does anyone have any advice or know a thread they can point me to? I've posted the results for 'lspci -k', iwconfig and 'lshw -C network' bellow:

My Intel Corporation WiFi Link 1000 Series wireless card stopped working yesterday after I did an update via Update Manager.After the upgrade, wireless is disabled and the option to enable it in Network Manager is grayed out. I thought that it might be the new kernel, but changing back to the old kernel I still have the problem.

I'm running Linux 11.04 and my wireless network was working just fine until today. I cannot connect to WiFi - it acts as if the device wasn't there. The hardware switch led isn't working. No matter how much clicking on it, it won't work.

The wireless on my 64-bit openSUSE-11.2 installed on my Dell Studio 1537 laptop stopped working some time back (possibly more than a one or two months back). I just discovered this last week when on business. I have not used the wireless under openSUSE-11.2 for a while so I am not certain what broke it, but I am suspicious of an update. I note openSUSE-11.3 milestone-7 works great with the wireless (on a liveCD). I note possibly two related threads, although I note no failed request for firmware in my case:request for firmware file 'iwlwifi-5000-2.ucode' failed [INTEL 5300 AGN] [OPENSUSE 11.2] - openSUSE Forums, and I see another thread here: Suddenly No Wireless Network Card - openSUSE Forums... but I can not tell if what I have is the same problem, so I did not add to those threads. In my case I can scan for the network, and see the SSID. An ip address is assigned. But a ping does not work.
Some details, the wireless is:
Code:
04:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection [8086:4235]
Subsystem: Intel Corporation Device [8086:1121]
Kernel driver in use: iwlagn
In terms of installed apps:
Code:
rpm -qa '*wireless*'
wireless-tools-30.pre8-5.1.x86_64
wireless-regdb-2009.09.08-2.2.noarch
[code]....
I know the router wireless network is good, because I can connect to the router via wireless with another laptop (old Fujitsu-Siemens Amilo 7400M with older Intel wireless), and the router wireless also works with this Dell Studio 1537 PC (with same hardware) but with openSUSE-11.3 milestone7 version.

I've been running Ubuntu 10.10 on this ThinkPad for a couple of months now, with absolutely no problems at all.The wireless was working fine earlier today out at a coffee shop. When I got home and turned the computer on, the network applet just showed a "Wireless is disabled" message.I poked around for a while, mucking with whatever I could (limited, unfortunately, I don't have great linux-fu) and doing the ritual reboot to see if that would get things going.I then spent some time reading through forum threads here, but didn't find any answers.Below are the results of the various commands as described in HOWTO post a Wireless issue (ticket) sticky threadMachine brand and model

I just got a new laptop equipped with some weird (at the present) hardware.
=> Intel Corporation Centrino Wireless-N100
=> Atheros Communication Device 1083
During the squeeze install no network harware was detected. (no wired, no wireless) On the net I read the wireless-N100 should be supported from the kernel 2.6.37 At last I tried Ubuntu 11.04 (LIVE) and the wifi was working. I also tried Fedora 15 (LIVE) and the wifi was also working. (kernel 2.6.38)But I want to stick to Debian (I am using it since Potato) What could I do to get at least the Wireless-N100 working ?

Alright this is my first post on here and I hope I got sufficient Information for you available. I ran Ubuntu based Distros before but this is the first time under a Debian based Distro for me. I got a newlaptop and this one does not seem to let me get my wireless to work after multiple efforts
My problem: My Intel Centrino N-6300 () does not seem to find any network connections.
My previous attempts: (Some of which required me to reinstall Suse)
1. I installed new kernels as my first assumption was that the kernel was not supporting it. I know now that it is supported.
2. I installed drivers from http://intellinuxwireless.org/ which was pointless.
3. I installed backports (THat was still under Linux Mint. Same problem there.)
4. I tried NDiswrapper without success.
5. I checked rfkill as you can see further down below.
Alright here are some of my info's I have collected so far. Let me know if anything is missing.
RFkill:
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

I am trying to get the RT2860 card in an Eee PC 1000 to work. I have tried Ubuntu 8.04 and 9.10, all the "fixes" below I can find on the web but nothing seems to work.
[URL] I downloaded the source code from Ralink and using module-assistant followed the instructions.
I can see the wireless network, it tries to connect but just keeps asking for the security key. I have tried WEP, WPA and no security at all but still no go. All works fine if wired. The F2 toggle seems to work OK, the WLAN is switched on in the BIOS. The "iwconfig" command shows the RT2860 in Ubuntu 9.10 but not in Ubuntu 8.04.

I have just installed Ubuntu 10.04 and the wireless connection on my Asus EeePC 1000HE is not working.
Network is seen but connection is always rejected and pops up the dialog requesting my password. Password is entered properly and using proper protocol (WPA2)
Network is working perfectly under Windows 7 and Fedora.

I've recently bought a Dell Latitude E4310 off ebay. Wifi chipset is Intel(R) Centrino(R) Advanced-N 6200 AGN. I'm using Debian 8.2 with Gnome 3 and I've installed firmware-iwlwifi.
Wifi shows up in Gnome upper bar, it correctly scans the networks and seems to connect successfully to my home router but internet doesn't work, it doesn't seem able to load any page.

Making a new thread now that I've narrowed down the problem. So I am trying to get some form of linux, ANY form, onto my Thinkpad X201. I've narrowed down the issue to probably being due to this integrated graphics card. I had at least gotten a mostly working setup via the 9.04 alternative install... I had a working system, except for one tiny problem: The system froze shortly 30 seconds after login, without fail. So, it was completely unusable unless I stayed in text only mode. I looked around, and the issue apparently was with my graphics card on the X201.
Here is the thinkwiki page for the laptop and the graphics card:
http://www.thinkwiki.org/wiki/Category:X201
http://www.thinkwiki.org/wiki/Intel_HD_Graphics
I had been attempting to manually update the kernel to 2.6.33 using .debs I found online - Someone suggested I try the newer version of Ubuntu, so I downloaded the Ubuntu 10.04 RC alt install CD... it installed fine, but when it starts up, it now just goes to a black screen. I can't even go into text only mode like the 9.04 alt install was letting me
I am very desperate, I am _very_ close to sending this laptop back to Lenovo, if anyone has any suggestions on how to get a working Ubuntu (or any other distro) install going on an X201, please share any details you can remember!

what it takes to get my wireless back up and working. It used to work fine under 10.4 My laptop is a IBM Thinkpad T42, that uses Intel wired and wireless nics. (correction, looks like the wireless nic is actually Ethernet controller: Atheros Communications Inc. AR5212 802.11abg NIC (rev 01) )

Since I originally started using Ubuntu (10.04) I have had problems with my wireless card. Now I have updated to 10.10 and it has stopped working entirely. I am using a "Dell Vostro 1520" with an "Intel(R) WiFi Link 5300 AGN" wireless card.Here are the details: 10.04
In this distribution version, if I had the wireless switch on my laptop activated at startup my wireless card would refuse to activate. There is a light to show when it is activated and this was off, but I checked anyway and wireless capabilities don't work when it is in this state. It didn't even resolve the problem when I switched it off and on again (although this caused the wireless indicator to blink on for less than a second when switched on).This was manageable because I found two workarounds:
1. Wait until my laptop had logged into Ubuntu, then activate the wireless card which would start and work as it should.
2. If I had already logged into Ubuntu I could put my computer on standby, switch off the card, come out of standby and reactivate the card while Ubuntu was running.As I said, this was completely manageable, and I got used to it. 10.10
Now that I have upgraded to 10.10 all workarounds fail, I can't use a wireless connection in Ubuntu, as my card won't activate, I cant even get the light to blink as I could before. The only way I can use WiFi is by switching to Windows.I tend to use Ubuntu for my university programming work.

I tried to install Fedora 13 on X201 for a dual boot with Windows. Since there is no CD/DVD ROM on my laptop, I created a new logic partition and put the DVD iso image file of Fedora 13 on this partition. I also extracted the isolinux and image directories out of the DVD image and put it in the partition. I used grub for dos to try to boot to the installation. Here is the command I typed in grub console (For whatever reason, it did not recognize my menu.lst).
root (hd0,4)
kernel /isolinux/vmlinuz
initrd /isolinux/initrd.img
and then boot. The booting process went well until it reached "waiting for hardware to initialize", and then the screen turned black. I thought this happened because Fedora could not recognized (X201 has an integrated Intel HD Graphics adapter). So I tried adding different options to the line kernel /isolinux/vmlinuz , such as "kernel /isolinux/vmlinuz text", or "kernel /isolinux/vmlinuz xdriver=vesa nomodeset", and it still did not solve the problem.

I was trying to update the drivers for my wireless card and it no longer works. I have a cisco pcmcia card that I got working to use as a backup, but I would prefer to use my internal card. The card is the Intel Pro 2200BG. Please let me know what information is needed to diagnose and correct this issue. I am relatively new to Linux (Currently using F10) and trying to learn.This is the iwconfig from my cisco card. The Intel card was working fine yesterday. but now doesn;t even show up.

I have a Thinkpad E420 and am having major problems getting the RTL8188ce wireless to work. I'm running 64-bit. I was following instructions from this thread: [URL]
I installed the drivers from the Realtek website for the updated kernel (URL is in the previous thread link). Modprobe didn't work, but it looked like wireless drivers were installed anyway after I did "make install." But I still run into this problem in the network manager: Enable Wireless is checked, but above it, Wireless Networks is greyed out with "wireless is disabled" underneath.
Later in that thread, someone posted a link to a PPA with drivers that should work. I could not get the PPA to work through terminal, but I did manually download and install those drivers. Same problem.

I've noticed that my wifi connection is significantly slower than my wired connection. Obviously wired is always faster, but when I boot in to windoze or use Mac, the difference between wired and wifi is negligible. I'm running Debian 8 testing on a Lenovo X201 with Intel Corporation Centrino Wireless-N 1000 [Condor Peak] network card.

When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.

Have been using Ubuntu Desktop Amd64 for 6months, on a dual boot alongside Vista64. Since first installing the OS, I have switched over to Ubuntu & use Windows only for heavy multimedia edition & the occasional gaming.I just bought a netbook and installed Ubuntu 10.04 LTS NBR. Works great, except for wlan. No propriety drivers available for my Intel Wifi Link 1000BGN.
I've spent hours trying to install iwlwifi, but the process is somewhat complicted for a noob such as myself.After much reading and trying, I've managed to download and install iwlwifi-1000-ucode-128.50.3.1.tgz, (following the http://intellinuxwireless.org/?p=iwl...=howto-iwlwifi instructions)and am now working on installing the mac80211 subsystem (following the http://intellinuxwireless.org/?p=mac...howto-mac80211 instructions)When running

pulled the wireless USB adapter out of the back of my laptop when I was using it. I plugged it back in and it can see my wireless network, but it can't connect. Everytime it tries, it just shows the connecting icon on the top bar for a few minutes and then says that the network has been disconnected.
I've tried uninstalling and reinstalling the USB adaptor, but nothing I've done seems able to fix the issue. Anyone know how to fix this?
The USB adaptor I'm using is a Trendnet TEW-424UB
