I have a small network (4 machines) with a Linksys WRT54GS running the Satori firmware. My network gets a fair amount of traffic in and out - I run a web server from one machine, P2P on another, have a file and media server, and of course do some e-mail and web surfing. I bought the Linksys to replace an SMC Barricade I was having problems with. The Barricade would lock up every several hours under heavy load and would have to be reset (sometimes a software reset worked, sometimes I would have to pull the plug). The P2P software causes the most traffic (and is probably the reason my router was locking up). I was told that a Linksys router would be able to handle the traffic better, and I like to idea of being able to use hacked firmware, so I bought the GS. For a few months I had no lockups and even upgraded to the Satori firmware without any major issues, except that I had some problems with Windows File Sharing over the wireless connection. I disabled the loopback and now it works correctly, BUT my router is locking up again! It doesn't happen as often, but it's sometimes as often as once a day, or sometimes it will go a few days without locking up, but every so often I have to pull the plug, as there is no software reset (that I know of?). Could the loopback setting be causing these lockups now, or is there maybe something else wrong?
