Ubuntu Networking :: Intel Pro / Wireless 3945ABG Stopped Working - Solve This?
Aug 11, 2011
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...
What do you think? Wife just bought a new Compaq 610 series laptop. These are the wireless specs:
Code: 10:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02) 30:00.0 Ethernet controller: Marvell Technology Group Ltd. Unknown device 4357 (rev 10) Strange thing is when I ping the router, I get this, pings one time then dies: Code: anna@katie:~$ ping 192.168.0.1 PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.
I'm new to linux and I install ubuntu on my wifes laptop since it will hopefully slow down the amount of problems I have to resolve.I ran the live cd of ubuntu and wireless was working all ok, showed my wife around and she was like ok install it.I used the GUI and install ubuntu, and updated (apt-get update) after that the wireless is not working.I see the device, but have no idea whats wrong. Please could someone inform me as to which things to post in order to get it sorted. Since this seems to be the only issue.

I've tried removing and modprobing iwl3945 but no luck.
I have an IBM Thinkpad T60, running Ubuntu 10.04 (Lucid) with a dual boot of Windows XP. I am having trouble getting it to connect to my home wireless network, which uses WEP. It connected fine at my university when I first installed Lucid, but has not connected at home. I can see the network in the panel applet, with a good signal strength, but when I try to connect it repeatedly asks me for my key and never actually connects. I had this problem shortly before I installed Lucid, though it was working for a long time previously. I'm not sure what update caused it to stop working because I was at my university at the time, and it works fine there even now, so I didn't realize it right away.
I doubt this is a hardware issue because I can connect to the same network when I boot into Windows. I have seen posts about similar problems on the forums, but couldn't find any solutions that helped me.
Below is the information the wireless help guide said to post. Machine Brand and Model: IBM Thinkpad T60
I installed Maverick earlier today on a Dell XPS M1210, and everything works beautifully, except for one thing: the wireless card. It is an Intel 3945ABG wireless card, and I've tried searching around and have found nothing,
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'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.
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:
I have my laptop dual booted between Ubuntu 9.10 and Windows 7. In Ubuntu I randomly lose connection to the wireless network. It always works fine when I first boot into Ubuntu but after a while my wireless connection will go down. The signal strength meter will go to zero bars and the black popup message will appear that my wireless connection has disconnected. At first, if I just wait a bit, the connection will come back. However, after about 4 or 5 times of doing this it will then ask me for my password, and inputting the password does not reconnect me to the AP. I am finally forced to reboot. Then it works OK for a while again and the cycle repeats.
It works fine in Windows7 all day, every day. I have the Release Candidate of Windows7 so it's going to expire soon. I would really prefer to make Ubuntu my everyday OS on this laptop rather than pay for a Windows7 license but I cannot tolerate a flaky wireless connection.
I had 8.1 on this laptop at one point and I never had any problems with the wireless then, that I can remember. I had no Ubuntu for a while but then I came back with the 9.1 and was loving it until the wireless problem reared it's ugly head.

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.
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:
04:00.0 Network controller : 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:
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 clicked "Network Settings", and I found that the ip address was wrong, which is "192.168.1.10/24", and netmask field is empty, so I modifed the configuration file located in /etc/sysconfig/network, named ifcfg-wlan0, added one line(NETMASK= '255.255.255.0'), saved it and reboot the system. After rebooting the system, I still found the ip address is wrong and netmask field is empty, so I have to use ifup command to activate my card manually every time the system starts.
I am unable to get my intel pro/wireless 3945abg connected to my router. The firmware has been installed and at first was even able to connect, but now the access point doesn't even show up in network manager. I am currently able to connect using a USB wireless adapter, but for certain reasons, would prefer to use the former. I've looked over this page with no results.
It's also because I've never had any big problem. The last openSUSE I used without problems was/is 11.2(I still use it as main desktop because of problems since 11.3).The problem is - the DL speed is repeatedly drops down to around 156KB/s albeit my top speed of router-NIC combination is at 21-22MB/s. When this happen and open network manager and click/reload my wifi or restart wireless or even computer, the speed is back at the top. But after few seconds, minutes it drops down again, and so on. I made some images(to see it on the network manager draphs):after that drop-off:and restart wireless:Best chance to see it is when downloading more files with FreeRapidDownloader or JDownloader. Upload speed is OK. The first time I've seen this problem in 11.3, which i've skipped in hope that 11.4 will be ok and now, as the EOL of 11.2 is coming I'd like to go on.It's also desktop and installation media independent(Gnome works similar, DVD, LiveCD).I've checked many other distributions and none of them had this problem. But openSUSE is my love, so i need and want to solve it
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 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.
[west@garfield ~]$ iwconfig lo no wireless extensions. eth1 no wireless extensions.
I've always wanted to learn this branch of computing, and I do think it's rather interesting. So, I was following in unison both this and this, which so far just tell me to download ipwraw-ng and extract it, but when I cd into the folder, and say make, I get this:
Code: ibo@ibo-laptop:~$ cd Desktop/ipwraw-ng/ ibo@ibo-laptop:~/Desktop/ipwraw-ng$ make WARNING: $SHELL not set to bash.
I recently installed F10 x86_64 on my Lenovo T61 laptop, and while I'm quite pleased with F10, I am having a difficult time with my wireless card. I spent most of yesterday searching for a solution, but none have presented themselves. Scenario: I am trying to connect to a HIDDEN SSID with NO ENCRYPTION (work Wifi, don't ask) using network-manager and its associated applet.
Symptoms: I left-click on NetworkManager, select "Connect to Hidden Wireless Network", enter my information, NetworkManager does a few things, and finally I'm told that NetworkManager cannot connect to my network.
I have a problem with my Intel PRO/Wireless LAN 3945ABG, The laptop doesn't have a hardware "turn-on" button for Wireless device, normal "windows shortcut" aren't also working. I couldn't turn it on using Network Configuration, it keeps giving me this message:
Error for wireless request "Set Mode" (8B06) : SET failed on device wlan1 ; Invalid argument. RTNETLINK answers: No such device Determining IP information for wlan1... failed.
I have some serious trouble getting the Wireless connection working, using Fedora 13 on a Dell XPS M1710 laptop which has an Intel Pro Wireless 3945 ABG adapter. I have previously tried an earlier version of Fedora I think it was version 10, where it worked flawlessly out of the box, but all versions since then, simply wont work properly. I got the Fedora 12 64 bit working at some stage, after using hours and hours trying to get it working, and suddenly it did. Don't know what suddenly made it work, since I haven't made any new changes, just re-checked the old ones. But I needed to use Skype which is only in 32 bit, so I had to reinstall to a 32 bit version, and then couldn't get it working again.
I can get it to work with any Windows version, no problems. I have also tried with PCBSD version 7.x, 8.0 and today I tried the new 8.1 just to see if that worked to, an no problemos, it works perfectly out of the box, I could set it up in 5 minutes, even though I don't have any previous knowledge of PCBSD, other than a few short trial installs.
It has to be said that I am a newbee to any Unix/Linux, so I don't know how to troubleshoot properly, and have only tried a few things which I have picked up from other forums. But unfortunately nothing seems to work. The first thing I did after a clean install was I looked in the Fedora 13 documentation, that says I should check that the NetworkManager is controling the interface, I tried to start up NetworkManager but nothing happens, no reaction what so ever. I tried rebooting and then restarting NetworkManager, but no matter what I try, I won't work, not even if I am using the root account.
I noticed right after the install, that there was a choice of connecting to a hidden network in the lower right corner of the screen, but while I have been trying to get the NetworkManager to work, it has suddenly disappeared (I have disabled SSID broadcast on my Linksys router. I've tried to run lsmod and it seems like the right firmware is running, I think it was called IWL3945 or something like that. I think there were around 3 such modules running, plus a Dell module.
Another important note, before I even touched the the WIFI, I connected to the Internet via my normal fixed LAN connection, and installed all the updates that were available and rebooted the system. I am using an LinkSys WAG354G V2 ADSL router, where I have disabled SSID broadcast. Is there a kind soul out there, who has a good idea of what the problem is, or a good idea of how to troubleshoot it ? since a laptop without a WIFI connection is not of much use to me.
I've just installed F12 64bit on my notebook. Everything works great. Only problem I'm having at the mo is my WLAN is slow at DNS resolution. On wired it works fine. I know it's not my access point as it is part if my router and I've rebooted it a few times. My other wireless notebook (Windows 7, Intel 3945ABG) doesn't have the same issue, and this notebook didn't when on Windows 7. I'm using OpenDNS as my forwarders.When I open a URL in Firefox (3.5.5) it opens the site immediately on wired. On wireless it will sit for 3-4 seconds before opening the site saying looking up .................. Once on the site browsing behaves normally.Anyone else having similar issues?
I'm new to ubuntu and using 9.10. I have installed a dlink wua 2340 wireless adaptor and it is working properly. But after waking up computer by standby mode, wireless connection breaks and the wireless device is not mounted. Therefore I always have to shut down the computer and restart again to establish wireless connection.
My wireless is not working after a fresh install of OpenSUSE 11.2. I cannot connect in KDE or Gnome. I installed cnetworkmanger and I can't get anything to connect. My wired network card on this laptop has been down for a long time. All I have is wireless. I have to roll back today to 11.1 if I can't fix it, but I really have been looking forward to 11.2 for some time. This is really a stupid bug to have in supposedly production ready software. Maybe I should add that in KDE knetworkmanager does not load by itself. I have to load it manually via console every reboot. I get this:
> knetworkmanager Object::connect: No such signal QTreeWidget::itemDoubleClicked(QTreeWidgetItem*) Object:: connect: (sender name: 'twNetworks')
It puts the icon in the system tray, and annoyingly hides it, so it took me a while to evern realize it was there. When I point my mouse at it, it says "Networking Information Not Available". When I click it, it says Network Management Disabled. cnetworkmanager spews out a bunch of errors and finishes by saying it can't find any .service files. I configured the device via 'Network Devices' in YaST. Hardware info says it is using the iwl3945 kernel driver. Everything was fine in OpenSUSE 11.1 and 11.0.
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.
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?
