Just to let anyone interested know:-

I was having loads of problems getting into games, and being dumped off the Crysis network. I tried everything that EA suggested and nothing worked in the long term.

I was using the netgear N150 router. I swapped this out two days ago and have only been dumped out once - and I swear it was at least 90% of the time before.

I bought a Netgear N300 router, btw - didn't think it would make a difference, but it did.

I did Google to find a list of 4 that were specifically recommended for gamers, so I would suggest this for your locale.

Hope it helps someone out
