A little complicated to adjust, but then all the better

As mentioned above, you have to adjust everything yourself. So let either give advance from the supplier Danten, or otherwise get on the Internet.
Have about 30 Nibuten used to adjust the thing. But when it worked it was just around eingiges faster than my 2 hours before scraped Huawei B970 (no wonder with the old stuff ;-)).

Bin far begeister. Used it in combination with a TP-Link router and Powerline system. works without problems.
