problem with wireless networking

[terapin]

my laptop on knoppix on wifi was fine up till this morning, but then it lost connection, and I couldn't see my wireless router listed.

I checked on my phone and it is there.

I clicked around on the taskbar and saw an option to disable/enable it, I thought that might help, though now it doesn't list any at all and I can't see what I clicked there.

I have clicked "enable networking", but it's not showing any wireless networks.

Do you still have no wireless network after reboot of Knoppix?

[terapin]

Yep, still not showing any. It's not even showing the wireless adaptor. I think it may possibly be a hardware issue, it's a laptop so if I want to fix it i'll have to open it and that's a project. so i'll have to leave opening it up for now
thanks

Check your function keys.
On a laptop, one of your function keys toggles wifi off and on.
