Disrupts T-Entertain / IPTV by WSD (Web Services on Devices)

First of all the most important for me knowledge:
Since the unit was in my LAN, I had every other day only still images while watching TV (T-Entertain / IPTV). The purpose of CX17WF was responsible, on the idea of ​​the Telekom did not come in five months troubleshooting.
At first it seemed as if the only way to take the unit completely from the net. Meanwhile, I found out that it is enough "WSD (Web Services on Devices)" remedy under "ports".

Otherwise the device: it is not just fast - especially copying and scanning is much slower than in similar products in the category that I've met. The quality, are printed in the color photos with almost luminous colors, I find impressive.

The configuration is easy: printing, scanning, faxing - everything works immediately (Scan to SMB comes in handy) - also via LAN. Reviews in this regard here are incomprehensible.

POSTSCRIPT: After further weeks of observation I have to say that the CX17WF somehow manages that my Speedport W921V (router) periodically loses the Internet connection. And that happens when I turn on the CX17WF or he boots up from sleep mode. Shortly thereafter, the telephony and Internet LEDs on the router go out (DSL remains on) - not always, but always. I know that sounds implausible. I also can not find the cause. The only solution was, the printer now to address a USB Print Server, which many network functions naturally lost.
