Compaq Presario CQ62-227TU I since upgraded to 12.04.2, but the kernels in that line are still showing this behaviour. (Last one checked: 3.2.0-51.77)
I still have the 3.9.0-030900rc2 generic kernel installed from earlier testing, and the wireless connectivity does work under this kernel. (There is an annoying tendency for the ethernet connection to keep trying to connect even though there's no ethernet plugged in, but that's merely an annoyance.) -- 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/1155443 Title: RTL8192se kernel driver unstable in low power mode Status in “linux” package in Ubuntu: Incomplete Bug description: Behaviour noticed immediately after kernel upgrade from 3.0.0-31 to 32. When laptop is connected to power, all is as it should be. When laptop is disconnected from mains, and running on battery, the wireless will continue working for a while (less than a minute), then drop out and Network Manager will attempt to reconnect to the WLAN. It will fail (timing out) forever until Network manager gives up. No indication or cause of failure is given in any logs, or in dmesg. When the module has failed, then running "sudo rmmod rtl8192se rtlwifi mac80211 cfg80211 && sudo modprobe rtl8192se" in a terminal will re- enable wireless, but it will inevitably drop out again just as it did before. Reconnecting mains power will also restore stability. (That is, if the wireless has failed, reattaching mains power will not of itself restore it, but if the kernel module is rmmod/modprobe-d back in, it will remain working correctly, and not drop out again so long as it is on mains power.) I have since checked under 3.0.0.31 again, and this problem does not occur. It looks like the rtl8192se module is unstable when the Power Management settings are on battery mode in this kernel version.
