I bought an Airport Extreme 6th generation router and I'm not able to make internet stable. It is connected through Ethernet on a DSL modem and it keeps drop out internet connection two - three times per day. When internet drops out, airport led remains always solid green and the only thing that works to recover connection, is to turn off DSL modem and back on (if I reboot airport connection doesn't re-establish, problem solves only when restarting DSL modem). I have tried hard reset airport extreme a couple of times, give a static ip to airport but nothing works. It drives me crazy. Any ideas to try are much appreciated.
