I am experiencing similar issues on a non ath5k driver. My chipset is Intersil ISL3890/3886.
Network Manager roams to (none)(none) every 2 minutes or so, disrupting downloads in progress. Also, on "busy" networks, system becomes very sluggish. Feels like the network driver is interrupting everything to deal with the traffic. Long ping times occur, and packet loss too. $ uname -ros Linux 2.6.28-13-generic GNU/Linux $ lspci 00:06.0 Network controller: Intersil Corporation ISL3890 [Prism GT/Prism Duette]/ISL3886 [Prism Javelin/Prism Xbow] (rev 01) $ dmesg [ 52.214232] p54pci 0000:00:06.0: firmware: requesting isl3886 $ lsmod p54pci 17280 0 p54common 23680 1 p54pci mac80211 217464 2 p54pci,p54common -- network-manager roams to (none) ((none)) - background scanning https://bugs.launchpad.net/bugs/291760 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
