Hello, the AVM 6840 is a super router, with many setting possibilities !! But, please note, the 6840 box works with the NON-Telekom tariff (Call and Surf Comfort via radio; 10GB + 7.2 Mbit) .Found actually, in the Treaty of Telekom (tariff only with routers Telekom usable ) .All pages viewed, therefore, blocked when using the 6840-by local telephone companies !!!
