Niestety nie jest dobrze, po włączeniu routera (po wcześniejszym odłączeniu go od zasilania) internet najczęściej nie jest w stanie samoczynnie się podnieść, a proces ponowienia połączenia po jego zerwaniu trwa kilka minut, i czasami bez ręcznego popchnięcia też nie startuje 
Rozważam powrót do starego modemu Huawei E398U-1. Jednak ciągle mam nadzieję, że z tym nowym też coś da się jeszcze zrobić. Szansa chyba jest, bo po podłączeniu bezpośrednio do komputera modem startuje szybko i raczej nie zdarza się aby zrywał połączenie.
Poniżej materiał do analizy dla Cezarego. Tylko w Tobie nadzieja
