COM port generally is not needed directly but it becomes extremely important if we have to unlock the device and send AT commands to the router. In most of the cases, executing setup file is enough to install the drivers but sometimes the procedure to enable COM ports becomes tricky and requires a lot of manual actions.

First Method:

Connect the router to the PC using USB cable.

Second Method:

Sometimes the above method won’t work and instead of displaying COM ports it displays HUAWEI_MOBILE having a yellow icon. It is an indication that the drivers are not installed properly and need to be fixed. This problem can be solved by manually installing the drivers available in the operating system.
