    I just upgraded the firmware on my parents' WRT54G because of the supposed security problems, and now the wireless functionality of the router barely works. Wired computers run fine through the router, but wireless computers are only able to see a few webpages (e.g. Google and MSN) but not others (e.g. Yahoo), and everything is very slow over wireless. They tell me that turning off the WEP and/or MAC filter seem to help. DOes nayone have any idea why this is happening, and if so, how to fix it?
    Also, does anyone have an archive of old firmwares that I could use to downgrade teh firmware back to 2.02.x or something?

    Turns out the problem was that the MTU size was changed on reset, which messed with my parent's DSL modem. I think the number ot use is MTU = 1492, but ask your provider.
