Wireless Internet Access

I would like some input regarding a problem a friend is having with static electricity from nearby storms and perhaps other sources coming in on the input line from the antenna on a wireless installation. It is destroying his router on a regular basis. The person who is experiencing the trouble is running a Linksys router. The wireless ISP has replaced the router several times but the problem persists and there doesn’t seem to be a fix for the recurring problem. Any thoughts on a solution?
