Hi everyone, I eperienced the same problem with my laptop Acer Aspire 8951g (Atheros wireless card). The problem appeared suddenly, continuous disconecctions and messages in /var/log/syslog inticating disconnections with reason=4.
I noticed that it doesn't only occur with my card model and every time someone fixed it was in a different way, and noone is sure about how it fixed the problem. So I tried everything: Adding the nohwcrypt=1 option to the modprobe module, install compat-wireless drivers, changing my wifi configuration (some people fixed it by changing WPA/WPA2 to WP" only) installing wicd, and even reinstalling a clean copy of ubuntu. I though it was a specific problem of linux, since I worked in windows 7. But I was skeptical and finally I found this post. http://www.verboon.info/index.php/2011/03/using-the-windows-7-event-log-to-check-wlan-link-quality/ So I found that it also happen in windows, but W7 is very fast recovering the connection. All the clues pointed to the hardware, I opened my computer played with the wifi PCI card. I made a mistake connecting the antenna and after that the problem remains and was also noiteable under Windows (I got the same errar message related security, nothing related with the signal). So I checked the connections again (this time I plugged all correctly ) and it finally worked in windows 7 and ubuntu. In summary, I think this is a hardware problem, but depending on the SO, the kernel and the software it can be override with a quick reconnection, so most of the people doesn't notice it until it turns really annoying. I hope it helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1003406 Title: 168c:0023 Wireless network continuously disconnecting and reconnecting To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1003406/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
