WiFi turns off and is only available after restart

[fredaburg]

The title already says it. I'm new to Ubuntu and have a HP notebook.

Where can I find error logs, so that I can paste them here? It often happens, that WiFi suddenly turns off, and I can't search for new WiFi networks in my area. Reboot helps, but thats annoying.

Thanks,
Freda

To see the network statistics including errors:

grep . /proc/net/dev

To see what the wireless driver did in the system logs

sudo dmesg | grep $(sudo lshw -C network | grep -a11 'Wireless' | grep 'configuration:' | awk '{print $3}' | grep -v 'broadcast' | sed 's/driver\=//g' )
