The modem I purchased as a replacement for the falling out of my internal modem FritzBox 7270. It also works well with the Fritz box, but without the help of the Internet I would not have it Done. The main problem was the Fritz box. She had to move only to work with the modem, after IPTV has been disabled with the Fritz box, which was unfortunately nowhere documented. Also, I find it a pity that is nirgenswo noted in the description for the modem on it, neither the description nor on the home page, how to get into the internal configuration program the modem. Neither the IP address, yet the password for it to be mentioned. Only a long search on the internet brought for the solution. But since everything fuktioniert well.
