You are best to use your own router mate, i havnt used a stock router from virgin since 2005 and i have never looked back.
I received the new white hub at xmas aswell and unknown to me i heard people had issues with port forwarding on these routers but it did,nt affect me as i,m using a ddwrt open source router, i did notice the lights changed colour last month to pink, i assume that was a software update to maybe fix the issue you are having but unsure.
