Hi, I've read a big part of the day on this site to try to find something about my problem. The switch part of my router is working perfectly, with wired and wiredless computers talking to each other with no problem. 8) But the internet connection drop for no reason at all, with me doing nothing else than browsing. I upgraded my router to the new firmware : v4.50.6 from Linksys, not knowing at the time that other firmware exist for the WRT54GS. And now I've got the really funny "Upgrade are failed" if I try to put another firmware on it. Is there a way to downgrade my firmware?
