Don't bother looking for me to play online anytime soon. I was playing the game last night and my PS3 broke. This is a hard time of year to think about replacing it.
uPnP enabled? MTU should be set to 1350.
What version is it? You can find it on the sticker on the bottom.
Also, do you have the latest firmware installed?
Anyone have any idea how to adjust the NAT settings on a Linksys router? I can't find it when I go into the Admin menu. I have a Linksys WRT54GS and last week it decided to change to Moderate, when it's been open for 3 years....WTF?! I never did...
