I have precisely the same problem (including Caps Lock flashing) on my Toshiba Satellite L355 (x86_64 architecture) using the built-in Wireless WiFi Link 5100. Again, wired Internet works flawlessly.
The difference is that I've been using Jaunty for a while with no problems. So kernels 2.6.28-11 and 2.6.28-15 worked fine. My problem apears to be related to the 2.6.31 kernel in Karmic. -- When using my laptop wifi card to connect to a WPA2 network, the kernel crashes https://bugs.launchpad.net/bugs/353062 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
