I setup a small network for a friend. Well the router is a V5 and it runs for about 4-5 days and then it just drops the ip lease. Unplug the router and plug it back in and away it goes again. I flashed the latest firmware thinking it may be a bug but no go. It just keeps doing the same thing. One of his computers is older and has a 10mb card in it. I thought that may be causing the issue but haven't changed it to confirm if that is the problem. As I wouldn't think it would make the router do that. Has anybody experienced this or any ideas as to how I can fix this?
