Any ideas

Could be a short lease on the DHCP, (give your PC an IP address).

To check this, when you loose your connection try this procedure.

Start > Run >

cmd

.

In the command box, type the following

ipconfig /all

to check the LAN connection status, then

ipconfig /release

followed by

ipconfig /renew

to renew your IP Lease.

If that works then post back here for a permanent fix, or configure a manual IP address if you know how.

You could try updating the Routers Firmware, the software and procedure will be available from the manufacturers website, but not the easiest thing to do.

I had another PC with fresh windows and it worked there. So I reinstalled Windows and it works fine.
