My Huawei EC1705 USB modem was working fine until recently I plugged it in and it said the modem could not be detected. I tried using other USB slots, and it said the same thing. I had a friend download teh drivers software onto my laptop but that didn't work either. Is there anything I can do apart from having to purchase a new USB? I don't have WiFi where I live, I can only get it while at work. And I'm not very technologically astute so if someone can give me instructions in the simplest of terms I'd be grateful (lol).
