Temat: Huawei B818 LTE - przerwy w dostępie do internetu

Od kilku tygodni mam duże problemy z internetem LTE.
Modem to Huawei B818, sieć Spusu.

Na ogól strony się nie wczytują, jak sprawdzam ping to z jednej strony jest odpowiedź a drugiej już nie.
Kilka restartów routera Huawei i na jakiś czas pomaga.
Co może być przyczyną, co można jeszcze sprawdzić?
