I noticed something yesterday while playing around with Nmap. I did a scan for IP addy's on my home router and it made the router reset. I was scanning my AT&T 2Wire. I wanted to see the different device signatures; iPhone, iPad, Comps and other wireless devices. By the end of each scan "root@bt # nmap" my router would reset and drop all connections. I got out my old Linksys '54 and a newer Cisco N band router, hooked them up and got the same thing. Reset. I went to Zenmap and tried the same command, same thing happened. Am I doing something wrong? It does not seem like that would be a desirable effect for a scan to crash the router.
That first scan cost me a night on the couch, My wife was watching a movie on Netflix streaming.
