All 5 network adapters stopped working

[Guest PhilipKnowles99]

I have a number of network adapters installed on my Lenovo 3000 N200 including wired and wireless connections, internet tethered phone connection and VPN for Blackberry.

 

Last week all of these suddenly stopped working at the same time so I upgraded drivers and tried different connections all to no avail. The machine will not connect to the local network or the internet by any means at all.
