Assuming you are on cable....I suggest you buy this wireless Buffalo router from Ebuyer for around £26 + p&p.

Then send the Belkin back for swap out, and keep it as a spare for resilience (or a bookend)

Sorry...should have checked out that it was an ADSL router. Again would suggest a Buffalo router, which I have installed for a friend. Stable, reliable and very neat. The routers pretty good too! Price upped to £37 pounds + though......
