Connected wireless with no internet connection

[Mary]

Help - At Christmas we set up a wireless connection using a Belkin Router
between our main PC and another desktop pc that are both Vista, it ran fine
until last week when we lost internet connection on both pc,s.

We have got connection back on the main pc direct to the modem and through
the router but on the wireless pc is connected via wireless but with no
internet connection.

Neither Belkin, PC Worlds PC Performance or Virgin Media have been able to
help.

Any ideas???
