hmm - I was thinking that the encryption pgms on his setup were causing the main problems.
the wireless super encryption - could be totally blocking out your other pc wireless signals.

I guess that my theory is blown now since his is off and you still have troubles...

I'm surprised that gov doesn't spring for a second line dedicated for employees secure access from home - seems they could be able to get a bulk discount LOL.
