** Description changed: I am on Ubuntu 12.04 64bit updated to 14.4.2012. With the kernel 3.2.x series ath9k driver got many additional stability, but it is just not enough. Under many connections the bandwidh of my wireless connection breaks down <12bytes from 700kbit at maximum. This is nearly a collaps of the wireless connection and should not be. Reproducing: 1.Go to http://software.opensuse.org/121/de and choose the torrent download option for the openSUSE dvd. 2.Start the torrent with transmission. 3.See your bandthwidh going down with increasing numbers of torrent peer connections.(no neccessary datatransfer - only connection establishing). - The hardware I use is TP-Link5008. + The hardware I use is TP-Link5008 - Atheros AR5416 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-generic 3.2.0.23.25 ProcVersionSignature: Ubuntu 3.2.0-23.36-generic 3.2.14 Uname: Linux 3.2.0-23-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
