FYI you can't use 5GHz and connect a PS3 wirelessly, as it only uses G mode which is not compatible with the 5GHz mode. Boo to Sony on that one, no N upgrade in sight to make that work that I've heard of. But if you connect that with ethernet and have no other devices that must use G only (like some phones, old computers) then it can be better, with the afore mentioned possible signal strength through wall issues. Also note, really old stuff that has wireless-A (one of the first standards) will work with 5GHz, so if it says a/b/g rather than just b/g you're good too.
