Ubuntu Networking :: 10.10 - Wireless Disconnects At Random

Apr 21, 2011

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.

Networking :: Random Wireless Disconnects In OpenSUSE 11.1

Sep 8, 2010

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

Code:

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.

Debian Hardware :: Random Wireless LAN Disconnects

Aug 14, 2014

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

Ubuntu Networking :: Wireless Constantly Disconnects?

Oct 4, 2010

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,

Fedora Networking :: Wireless Disconnects With WPA - 2.6.27.12-170

Jan 27, 2009

After I updated to kernel-2.6.27.9-159.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 2.6.27.12-170.2.5.fc10 kernel currently in updates-testing has solved the problem.

Ubuntu Networking :: Lucid Wireless Randomly Disconnects

Jun 25, 2010

After upgrade to Lucid I have experienced intermittent wireless disruptions. The wireless just cuts out and reconnects.And I was hoping to continue or follow up on the same thread however with the released version.I tried replacing network manager with wicd and I tried the other driver options both without success.I'm currently using the Broadcom B43 driver, when I tried the Broadcom STA driver wireless would not work. I use the 64 bit OS, and this problem did not appear prior to the upgrade.

Ubuntu Networking :: Natty Narwhal Wireless Disconnects?

May 8, 2011

I recently upgraded from Maverick Meerkat to (classic) Natty Narwhal Ubuntu Linux. I am running on a Toshiba Satellite A665 (Intel i7). I use a wireless internet connection. Under Maverick, I had no issues. Under the update, I am finding that occasionally things stop working: The indicator Applet looks fine, but from a terminal, I find that I am no longer able to ping my own router (less than 10 feet away.) This behavior occurs after working fine for a few hours. I am unsure if anything in particular triggers it (I will report back if I determine a particular cause). I have a few other computers (2 running Windows, and the other Maverick Meerkat) -- and they are unaffected. Turning wireless off and on resolves the issue for me on Natty. Rebooting also works. Here's some hopefully relevant technical details about my system:

Code:
~$ rfkill list all
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

Ubuntu Networking :: Frequent Disconnects From WPA Wireless Router

Ubuntu Networking :: Wireless Randomly Disconnects - Only Works Again After Reboot

Jul 3, 2010

I'm having a problem with my wireless connection. When it runs, it's perfect, but every once in a while (and increasingly more often) it randomly disconnects and doesn't reconnect when I click reconnect, even if I manually disconnect it. Every time this happens, I have to reboot the system, after which it works perfectly. Then it dies again.

I've checked around the forums, there are some similar threads but they seem to be specific to the wireless card. The reboot method works, but I'd really like to find a way to solve the problem without having to resolve to the Vulcan nerve pinch. I'm a real newbie to Linux and the more complex side of computers in general, and I hardly know what is what, so please excuse me if I seem a bit thick.

Ubuntu Networking :: Laptop Going To Sleep Disconnects Wireless At Router

Jan 21, 2011

Running Ubuntu 11.04 on a Gateway LT3103U netbook. It's running fine except for that fact that when it goes to sleep (timeout or lid closed) or going into suspend or otherwise restarted/shutdown, my router restarts. It's a DLink DIR-655 that has been working fine until I changed this netbook to Ubuntu.After installing Ubuntu on the netbook, it found my SSID being broadcast and I added the connection by supplying the WPA2 password. I have full network access (local and internet).

It's just the router restarts and all my other machines lose connections. The router is using DHCP but supplying IPs based on MAC. Netbook is set to use DHCP.

Ubuntu Networking :: Lucid Wireless Disconnects For No Reason And Can't Find Password

May 3, 2010

When I installed Lucid I got temporary wifi connection. It disconnected for no reason. Then it was constantly trying to reconnect, telling me my password was wrong. Which wasn't wrong at all. So I installed Lucid again from scratch and now everything seems to work fine. The only thing I didn't do was install the 'restricted drivers'. This was only one driver for me which had to do with my modem. Wifi works perfectly now. I hope it stays that way .reinstall Lucid and DO NOT install the 'restricted drivers' for your modem

Ubuntu Networking :: Intermittent Internet On Wireless/wifi - 10.10 Disconnects Repeatedly?

Dec 31, 2010

I just upgraded to Ubuntu 10.10 because I was facing internet problems with previous Ubuntu 9.04 after I upgraded it with downloaded software. And now, 10.10 connects to wireless, but shows web-page some-times and repeatedly disconnects. Earlier it wasn't reaching Internet at all. Some of the topics here helped a lot. But this intermittent internet seems not going anywhere. Wired Internet connects easily though.

I've tried :-

-disabling ipv6..... first in Firefox, then in Kernel also
-Setting DNS.....System> Preferences> Network Connections
-setting static Ip

The system still gives trouble.

My system is Asus UL20A.
Wireless:-Atheros AR9285

Ubuntu Networking :: 64 Bit Bcm4311 Wireless Random Kernel Panics?

Sep 22, 2010

I have this weird issue which only appears when I am using 64 bit Ubuntu. Every now and then my laptop seems to go into a kernel panic (system unresponsive, numlock and scrollock lights flash repetitively) only when I am using the broadcom wireless. I can connect to my wireless router and use the internet and local network, but eventually, kablamo, crash, bang, boom. The only way out of the crash is to power off completely. After repowering, the wireless network is fine until the next crash. There does not seem to be a pattern or time period to cause this crash either. I have purged network manager(which I couldn't get to use my wireless) and am using wicd, which allows me to connect wirelessly.

Here is the details of my system:

Dell inspiron 1520

Ubuntu :: No Wireless Driver - Disconnects Every Time Trying To Go Online

I've just installed Ubuntu on a new netbook, getting rid of windows in the process. I had tried it on another computer, installing it alongside Windows, and liked it enough to want to install it fully on my new netbook. I followed instructions, downloaded it to a USB stick, and then installed it as per the instructions on the Ubuntu website. All seemed fine until I tried to connect to my wireless network, when it appears there is no wireless driver. I tried plugging in the ethernet cable, but it just disconnects me every time I try to go online.
