I bought the Huawei E3520-2 because we receive in the countryside only Internet over 3G. He puts on the UC100 to the TL-MR 3420 by TP Link. I turn on the router in the attic with a simple Internet needs a switchable radio-controlled socket on and off. The units harmonize very well and now reliably for months together. Conclusion: the docking station works well and reliably.
