I confirm the bug (Thinkpad T61p with iwl4965 from linux-backports- modules-hardy) but not the workaround (only reset can bring wifi back on).
On software rfkill (Fn-F5 here) both bluetooth and wifi go off, but then wifi goes back on in 15–20 seconds. Pressing Fn-F5 again causes bluetooth to go on and wifi to go off, and after 15–20 seconds wifi is on again. Pressing Fn-F5 quickly a few times can cause wifi to go off forever (i.e. until reset). -- iwl3945 | iwl4965: Wireless can't be activated after disabling kill switch https://bugs.launchpad.net/bugs/193970 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
