I'm using a WRT54GS v4 router, and eversince I switched to the latest tomato from Thibor, my LAN line (wired computer) started to drop connection every few days of use. Could this be the router or is the internal network card going bad? This also happen every time I transfer files into my NAS storage. I really like using tomato because QOS seems to be working much better than Thibor, and I do not want to switch back. Any advice would be great. All my computers are Vista and 1 XP.
