I researched this problem before but couldn't come up with a good solution. I have a linksys WRT54G router (wireless) and a PS3 that's connected wirelessly. I also have a D-Link router that's not used often. Let me clarify beforehand, I can't switch the routers out and don't really want to and that both routers are far away from each other and I would have to move my PS3 to use the D-Link. I love my linksys, it's what I use to connect to my MBP and media center PC. But I have this problem that I can't figure out. Anytime I turn on my PS3 or change games my network is restarted. Which means I have to wait for my system to log back in, and Adium to log back in and stop using the internet on my computer. I realize this problem was caused by the UPnP configuration on the PS3 and my router. But since I have a Media Center PC (which runs ORB) I can't really turn off the router's UPnP. I know on pre-2.42 firmware you could easily turn it off. I went through the custom settings and turned it off but I still have the issue. When I turn off the media servers everything works well with no issues, but when I turn it off my Orb folders go away,, which defeats the purpose of having it. It's conveniet when I don't want to load all of the music I like onto my hard-drive. It also prevents me from having to use the browser to open said files (still have to for TV though). Also my linksys is much faster. As for the D-Link it's not attached to any media and doesn't have any restart issues. But it is VERY slow and drops my PS3 quite a bit. The computer it is attached to is very old, rarely used and takes 10-15 minutes to load and would take a long time to change routers and install software. Sorry for the long read appreciate any and all help.
