The TD-W8970B and I had a difficult start, since it runs at us but without interruption The start was especially difficult because my splitter has an RJ45 (network) jack, the modem but a RJ11 ("ISDN") socket has. The modem itself were 2 RJ11 cable at (why 2?), So that the correct cable was missing. Not really tragic, because there are only the inner lines used and a RJ11 cable also fits indeed in a RJ45 socket. At least in theory. Me what it but for hours not possible to connect to the Internet. Only then did I noticed the cable as a potential problem, buy a new and so it was then. Since then, I am very satisfied with the device. Unlike my old wireless modem I have now no more disconnections, the reception is great and the speed also. That I can share USB flash drives on the network now or finally may adjust times that the modem to connect to the ISP updated at night, to crown my previous experiences.
I recommend everyone to be the first to make a firmware update. This is very easy and the new firmware brings among other input screens for the current ISP. Especially with the Telekom with ihrerer quite idiosyncratic construction of logins, this is a more profit. In addition, then vote the other parameters that you would otherwise have to be ergoogeln only.
The star trigger there that neither an appropriate cable RJ11RJ45 was placed, still a sliver (as it seems to be the case when model for Austria and Switzerland).
