I have been running Kubuntu 12.04 since its release and this problem has plauged my installation on my Acer Aspire V3-771G laptop. It does not appear to be load related. I am running the 3.8.0-27-generic kernel. I have tried the 3.2 and 3.5 kernels. The problem affects my wireless chip, AR9462, AND it also affects my ethernet chip, AR8151. The disconnect/reconnect is random. Sometimes the reconnect is almost instantly, sometimes almost a minute can go by. I have tried WICD but the problem persisted, so I went back to the plasma-network-manager. I have played with settings of the ath9k PARMS vars. No joy. The atl1c module has no PARMS to set. The Win7 side runs both wireless and cable just fine.
Oh, if I use suspend then the network-manager doesn't re-enable. I have to change the "managed=false" to "managed=true" in the ifupdown section of /etc/NetworkManager/NetworkMagager.conf to re-enable the plasma- network-manager's ability to join and manage networks. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1040943 Title: Wireless -very- frequent disconnects in LinuxMint13 - Atheros AR9462 Status in The Linux Mint Distribution: New Status in “linux” package in Ubuntu: Invalid Status in Debian GNU/Linux: New Bug description: Wireless Connection disconnects very frequently, almost about every 15 minutes.
