JoeBloggs, I am sure that the v3 can do 10meg as it has a 10/100 port going in & four 10/100 ports coming out. As for the v2, I only have the info that others have given about their routers in the other thread I pointed to. Did you take a look at it?
As Zeph pointed out, it shouldn't affect your ping times, but will affect your download speed, i.e. you're only getting about 5-6meg at the moment instead of max of almost 10meg. A direct connection from the modem to the PC will give you an idea of what your best speed could be. Hope this makes sense..... I'm no teacher
