Ok. Update. Today i received a replacement router. Isp was also convinced it was fubar. So in a good mood i connected the router, logged in the router, updated the firmware and bricked the POS!!! What the hell! This new isp is giving me a headache. Spend another 20min on the phone calling the helpdesk. Though the guy was really cool and is sending me router nr 3 asap, i really am fed up with this Telfort company. In my 8 years with previous isp i never had so many problems. Hope the new one will work like it should. But i ain't touching nothing on it, that's for sure.
