I think I'm experiencing a similar issue - at least it seems to have happened at similar kernel release. For background I'm using a PCI wireless card with no physical "Off" switch. The same PC has been working since feisty I think.
On recent kernel releases the setup works fine for a day or so, and then the wireless just flatly stops working. The PC doesn't suspend like the previous bug reporter, but I do get the following in /var/log/messages kernel: [617690.000056] b43-phy0: Radio hardware status changed to DISABLED Again - I'm still experiencing this with 2.6.31-20 -- b43 hardware status changed to DISABLED after suspend https://bugs.launchpad.net/bugs/505821 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
