While I think Wired could be better, and offer slightly higher speeds, it's not possible due to the location of my PC compared to the PS3. I was using a Linksys wireless router for a while, and it was decent, but I switched internet companies, and they gave me a free "Westell Model 327W" DSL modem. It is wireless, and it works excellently. I have all my handhelds and laptop wirelessly running off of it, and never have any problems.
Again, I
could run an ethernet, but it would be about 100+ ft., and that is stupid when I have a wireless router that works fine. Plus, it's one less wire behind the rat's nest that is my entertainment center

. I'm all for a wireless future, uh huh.
