@dsjack- I could and I've been using one but my room is on the otherside of the house so I need a 50 foot one and its annoying to have it snake through the house.
@Psuedomelon- I have very recent firmware and its not that as its been unable to do this with the xbox and wii for years.
@mooster- There is a cordless house phone right next to the router. I doubt thats causing the problems though as my computer is in the same room as the ps3 and it connects wirelessly to the router at (usually) Full strength. What exactly should I be looking for when checking its settings? Do I need to change the wireless channel to a certain one? I remember people saying that for the will I should make sure its on channel 1 or 11. Thanks again.
