I bought the MR3420 with a Huawei E3520-2 because we receive in the countryside only Internet over 3G. That is mean hamlet of second router, I've tried. The others were either not compatible with the stick or did not have sufficient WLAN coverage. This router is now working reliably for months and offers numerous setting options via the web browser menu. In particular, like with the WPS function. About Here you can add new wireless devices (eg. WLAN Repeater Fritz) to the router, without which I must to the device itself. A E3520-2 Huawei stick is on UC100 on 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 router works well and reliably.
