I can't connect my huawei E5372s BOLT to my internet provider which is STC. I just bought it and i followed the instructions in the manual on how to set it up through the web management page using http://192.168.1.1 as instructed in the manual. However as i set it up, it says failed. And as i read at the status, it detects a signal but it is still disconnected. What will i do?
