This may help or be no good, brother...err i mean, bud (I'm being ripped for calling people 'brother' at the mo) but when I linked my xbox to my Netgear router, when I first had wireless, it would automatically cut out after 15 mins and I couldn't work out why. If the router didn't receive activity after 15 mins it would automatically cut out. For some reason it didn't recognise my xbox live activity; even though I was on there. I phoned the provider and he changed a pre-set timer on the router and all was good. May help......may just be a minute of your life you wont get back after reading.
