I have a linsys router wrt54G ver.2 with current firmware. About a month ago the router would start dropping client connections to the internet every other day or so. I am unable to get internet from any machine on the network however when i use the ping utility on the router admin interface it can get to the outside world just fine. It seems to happen around the time the isp hands out a new lease. i have been through the config about a hundred times now and can't figure it out. the only thing that cures it is resetting the router which is getting very old. any thoughts?
