Output of wifi related entries in dmesg. (This might be in other logs, but thought I'd add for completeness.)

Basically the wifi icon disappears and I'm off the network. I can't get it back until I reboot the laptop. However, it seems that there are issues reported in dmesg which indicate there are other firmware related issues.
