Well the PS3 only supports Wi-Fi b/g so no point of getting a Wireless N Router.
Personally, I have a Linksys E2000 Router which supports Wireless N only. I set it to Wireless G mode though so it works with my PS3.
dont know how much it costs, buts its truly one of the best
lol if he is having problems with his current router (probably G) then what makes you think another g router will help? He should go for a linksys wireless N router like the e series
The PS3 doesn't utilize the N band, so it makes no difference.
I don't know why i said that lol. I think maybe i wanted to say that that is an old router, so he should go for a newer more modern one.
