[SOLVED] Network lost, how can this be?

[ChrisL]

I'm guessing this is desktop, with a WiFi USB device plugged in.?

If you click on the Network icon down in the bar near to the clock
Is there a "Tick" mark next to "Enable WiFi".?

If NO, try to click it to re-enable.

If YES,
click it to un-tick it to disable it, then re-boot, and then re-tick it to re-enable.

I have had an occasional it appeared to be enabled, but wasn't.

I had a similar issue with a USB plug-in wireless, would not seem to recognize it although it had before.  I finally unplugged, plugged it into a different usp port and it worked.
