Ok, I swapped out my old Intel 3945abg card with a new intel 5300bgn wifi card. Reliability seems to have increased, but problem still occurs. See attached for dmesg output of dropout with new wifi card installed, including two instances of "wireless disabled by hardware switch."
It leads me to believe that the problem was at least partially hardware... I will test the new mainline kernel and report back... ** Attachment added: "dmesg output with recurrence after hardware swap" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1296504/+attachment/4429004/+files/dmesg.txt ** Summary changed: - iwl3945 wireless connection becomes unreliable + intel wireless connection becomes unreliable -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1296504 Title: intel wireless connection becomes unreliable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1296504/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
