Bought the Surf Stick for the operation of a wireless router (TP-Link TL-MR3220 3G / 4G wireless router). At first everything went super, from installation through to operation. Reception sensitivity seemed ok, compatibility with Eplus and Vodafone easily. Likewise, the menu, accessible via the browser via URL: //192.168.1.1 I find fine. While not perfect, but simple and clear everything understandable. Incidentally, also in German. The problem of surf sticks - in conjunction with the aforementioned router: there are fairly frequent interruptions of Netzerkverbindung. And not just in low mobile data signal, but also in close proximity to a transmission tower at a railway station (where one of the test points is). And not only during periods of congestion at 19:00 h in the evening, but completely randomized. Help make then: wait off the router for a few seconds and then on again. When that happens once a month, it would be necessary nor tolerable. But it was more often speätestens once in 48 hours. Unfortunately, no automatic reconnection takes place. I then bought the Huawei E3131 Surfstick. So now I had 3 weeks still no single link failure mitt the TP-Link TL-MR3220 3G / 4G wireless router. In addition, the E3131 sensitive and has an antenna connection. That's why I sent the E303 back.
