Witam,
do modemu Blueconnect Huawei E122 zakupiłem router TP Link MR-3220 v2 w nadziei, że będą ze sobą współpracować (na stronie producenta jest kompatybilny)
Niestety po długich próbach połączenia nie udało mi się nawiązać połączenia z Internetem blueconnect.
Próbowałem wpisywać różne kombinacje haseł i APN
APN internet, login/pass puste
APN/login/pass: erainternet,
dial-up #99*
Dla porównania połączyłem się bez problemu za pomocą Aero2 na Huawei e3131-s2, za równo przez Aero2 jak i przez Blueconnect...
Czy koś ma jakiś pomysł jak rozwiązać problem z E122? Soft mam najnowszy (TL-MR3220_V2_130423), modem jest wykrywany jako "identified"... Na stronie producenta nie ma plików BIN dla E122...
Ew. proszę o propozycję jaki modem najlepiej kupić dla Blueconnect, żeby był najtańszy i kompatybilny z MR-3220?
Bezpośrednio z komputera (Huawei E122 w USB) nie ma żadnych problemów z łącznością? Masz dostęp do internetu?
Z komputera Internet działa, chociaż modem się grzeje (czuć że jest ciepły, chyba trochę bardziej niż normalnie). Czasami jednak wyskoczy komunikat w stylu: "Proszę się najpierw zalogować przed połączeniem", i wtedy muszę 3-4 razy kliknąć uwierzytelnij i się łączy... Ogólnie modem ma już z 3 lata... Czy może on być "uszkodzony"?
Trudno teraz coś powiedzieć, choć nadmierne grzanie może powodować dużo większy pobór prądu a co za tym idzie problem na routerze którego wydajność prądowa gniazda USB nie jest zbyt wielka a co za tym idzie może stwarzać problem w stabilnym połączeniu z routerem.
Pokaż z menu routera - System tools - System Log
o można się dostać do jakiś logów na Routerze, żeby móc sprawdzić co dokładnie się mu nie udaje podczas łączenia się poprzez modem e122? Bo obecno to wygląda tak, że modem jest wykrywany, podejmuje próbę połączenia i po kilku próbach wyświetla, że modem jest "unplugged", dodatkowo zdarzyło mi się, że podczas zabawy z Aero2 i E122 cały router się restartował (wszystkie diodki gasły i odpalała się procedura startowa)... być może jednak coś tam może mieszać ten modem, skoro podczas próby połączenia cały router się restartuje... Albo przy trybie unplugged, muszę zrestartować router, żeby wykryć ponownie modem.
Jest może jakiś program, który sprawdzi mi modem e122?
Edit:
Ok, zaraz sprawdzę logi, musze to wszystko popodłączać raz jeszcze

gdyby komuś się chciało luknąć, byłbym dźwięczny 
Z logów wynika że brakuje prądu. Przy nawiązywaniu połączenia jest wymagane więcej mocy, której niestety brakuje.
Tutaj pomoże aktywny HUB USB.
Heinz, dzięki
Ale teraz pytanie, czy to wina routera (dostarcza za malo prądu), czy wina modemu- potrzebuje więcej prądu bo jest wysłużony?
No i pytanie w co warto zainwestować- w nowy modem, czy w zasilany HUB USB?
Aktywny hub USB to koszt 30-40zł więc zaczął bym od zakupu rozdzielacza, podejrzewam ze zawsze się przyda.
Ja chyba wolę kupić nowy modem plus kartę Aero2, bo ta na której testowałem jest pożyczona Mi się wydaje, że ten modem psuje lapka- ponieważ komp się zawiesza czasami i leci jakiś hardware failure bluescreen... wczoraj wygrzewałem lapka prime95 przez 3godziny i się nie zawiesił ani nie zagrzał... a HUB to jest półśrodek za 100zł kupue tego e3131-s2 do Aero i styka
chyba że polecacie jakiś inny modem, który by był przyszłościowy (LTE)...
Myślę że e3131-s2 jest dobrym wyborem w twoim przypadku.
