Probably alrdy a thread somewhere bout this but im new to the forum so i figured i'd ask straight up. I do alot of online gaming via my Xbox360 with Gears of War 2. Currently i run on a linksys WRT160N router to the wireless adapter on my console. im upgrading my broadband from 5mbps down/ .76mbps up to 30mbps down/ 2mbps up (the only quickest internet speeds they offer in my area). i was wondering if i should just stick with what i got and set up my router for port forwarding or upgrade to something better. not incredibly competent with networking so forgive my ignorance - any feedback appreciated - piece
