As far as the router in the area LAN / WLAN Ok, but the main focus was supposed to be on the connection to the mobile Internet via 3G / 4G. However, this is precisely the problem, LT. Compatibility List is a Huawei 3476s listed my Telekom Speed Stick LTE III is LT. Marked on the back of a Huawei 3476 without "s". Whether it is because it is so far geokmmen only once after the restart router to an LTE connection? I have not yet got it, bring about a connection to the mobile data network. The router will display "Identify successfully", "Signal Strength 67%", but regardless of whether connection Auto, On Demand, Manual, it will not connect. At the LTE stick it is not running 100% right on the PC. I had just once again a connection with the method "manually", after 1 minute was the Internet no longer and I have the router now has the status "unplugged" the USB stick. Affects me everything untrustworthy or stable and mature enough. Therefore, only 2 stars and the router goes back.
