The 3.2 kernel from comment #28 seems to be working a lot better. My wireless connects on log-in without any issues, and seems stable for 8+ hours. I've rebooted a few times over the past 2 days, and the wireless works without issues.
I downloaded the 3.2 kernerl from the link in comment #28, and installed it like this: dpkg -i linux-headers-3.2.0-030200_3.2.0-030200.201201042035_all.deb linux-headers-3.2.0-030200-generic_3.2.0-030200.201201042035_i386.deb linux-image-3.2.0-030200-generic_3.2.0-030200.201201042035_i386.deb During start-up, I saw some AppArmor errors, so I'm not convinced that AppArmor is working 100% correctly. Other than that, things seem to be working fine. root@theroux:~# cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=11.10 DISTRIB_CODENAME=oneiric DISTRIB_DESCRIPTION="Ubuntu 11.10" root@theroux:~# uname -a Linux theroux 3.2.0-030200-generic #201201042035 SMP Thu Jan 5 01:44:33 UTC 2012 i686 i686 i386 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/708712 Title: Wireless Card RTL819Xe on a Samsung N150 netbook To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/708712/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
