Just a tip if you're after a new router and want to save money.
There are lots of sky customers selling their wireless/ADSL routers on ebay at the moment. There are usually three types available
Netgear DG834GT (branded as sky)
Netgear DG934G (branded as sky but it's really a DG834Gv3 - not "GT")
Sagem (looks just like the DG934G, but it isn't)
All can be had for between £3 and £5 from ebay as by default they're locked to sky. But the Netgear ones can be easily unlocked with a bit of simple jiggery-pokery and will become the standard Netgear variety. These Netgear routers are ultra reliable.
Go to ebay and search for "sky router" and look out for the two netgear varieties.
