can my receiver share internet to two ps3's?

I was wondering if it's possible to somehow split the internet signal coming from my Uverse receiver.  Right now we have 3 PS3's and 2 receivers.  I have been using wireless to connect the 3rd PS3 but it is really inconsistent - lags, drops me out of games.  It's really annoying.  Is there a way that I can "split" the internet signal or use another router to be able to be "wired" to the internet to play on 3 consoles at the same time?
