Ubuntu Networking :: Random Wireless Disconnects - 9.1/Toshiba/Intel 3945abg?
Feb 22, 2010
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 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 use ubuntu 10.10 and disconnects from wireless at random. after it reconnects the the connection speed is very slow and unstable. It's not my router because it works fine on my sister's netbook (which is also running ubuntu) and it worked fine when I was running windows? I'm not very advanced with linux so you know. I don't have IPv6 enabled. My laptop is an "Advent QRC430" my wireless card is QCOM Q802XKG Wireless Network Card.
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 have a hp dv3 2110eg laptop with OpenSuse 11.1 (KDE 3.5.10) and Windows 7 dual boot. My wireless disconnects and connects automatically at random intervals. I do not observe this behavior when operating my laptop under Windows 7. Following some suggestions given in this forum , I uninstalled networkmanager and installed wicd. However, this does not seem to solve the problem. Given below are the relevant information. uname -r
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 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 cant seem to understand what happens to my wifi networking, i just installed ubuntu 10.10 today (completely erasing windows) on my toshiba satellite m645. Seems like my wireless card (the specs say its intel 802.11a/g/n wireless LAN) will only randomly detect the available networks or will connect only for a few seconds just after i just turned it on, then it will disconnect.
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 have installed Debian Wheezy on my laptop today, which went relativly smoothly. The only problem that is left (for now) is that my wireless LAN disconnects 1-2 times every 30 minutes, just to reconnect a few seconds later. Obviously that is very annoying, especially when watching streams on twitch, videos on youtube and so on.A thread I found on google suggested to use the command dmesg right after my wireless lan connection drops. So I waited for the next disconnect, issued the command and got the following output:
Code: Select allwlan0: deauthenticated from 00:1f:3f:d4:25:6a (Reason: 14) wlan0: deauthenticating from 00:1f:3f:d4:25:6a by local choice (reason=14)
I wondered what that reason code meant and found this website, which states that the code 14 stands for: Message integrity code (MIC) failure
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

I've tried removing and modprobing iwl3945 but no luck.
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.
Wireless worked fine on live cd, but for some reason not after install. I think maybe the driver is not loading, but I am a pretty much still a noob, so my opinion isn't worth much. If it is the driver not loading, I don't know what to do to fix it. Here is my wireless output information.

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 have recently installed the intel-wireless-tools and now my laptop detects my wireless router and connects to it but when I go into a browser I can access the internet. If I connect to the wired network no problems(same router) no go on Wireless.
I have recently installed Fedora 13 on my laptop, an Acer Aspire One D150. The laptop has an Intel 4965agn wifi card which worked flawlessly under Fedora 12. Now however it keeps disconnecting every 10 minutes, even if I browse the web. On top of this, it also becomes very hot, so hot that you can feel it through the plastic case.
Are Intel wireless cards compatible with non-intel-based laptops? In my case I wish to upgrade the current Atheros-based mini pci express wifi card with the Intel 4965agn. It is an Asus 4520 with an AMD Athlon X2 processor and nvidia nForce chipset.
I'm using an Acer Aspire One d250 running Netubuntu 10.04. The wireless connection to my router fails at random intervals and spends most of it's time trying to reconnect. It will occasionally ask me to input the password to the network, which is already entered in the dialog box, and clicking "connect" doesn't seem to make any difference. Also, when it is disconnected from the network, none of the other computers in the house, wired or wireless, are having any problems. If there is any more information I could provide,
After I updated to kernel-22.214.171.124-159.fc10 a couple of weeks ago, my wireless kept dropping the connection every few minutes (using an intel 3945 with the kernel iwl driver), particularly if secured with WPA. Updating to the 126.96.36.199-170.2.5.fc10 kernel currently in updates-testing has solved the problem.
