i work for a local ISP who distributes internet wirelessly and through PPPoE connection. Someone who actually wants to jam our network has connected another PPPoE server (the wireless network is unsecured) and now every time i dial, i get wrong username and password.
we tried mac filtering, but it turned out that he started to use mac addresses of other clients. i need the simplest solution (because i don't want to reconfigure more than 100 devices for the internet clients)
