Troubleshooter showing driver problem.I am also downloaded new driver from huawei site for checking error but it shows the same result.Till last one year there is no problem in my pc but today has this issue and wan port and HD audio driver problems ,please help me to solve these 3 problems.I want a quick response ,thank you for the consideration.

1. You may go for a System Restore. Select any restore point when everything was running fine.

2. You may need to uninstall the 3G Modem as well as its software from the Device Manager, reboot and then let the Windows detect the device . Finally you install it's software.

3. You may try to check i's health status on a different system or a laptop/PC.

do you remember if there any changes before this issue happen? installed software, windows update or any?

What is you antivirus status? did you used AVG?

I suggest you update all the driver from the Asus site after performed system restore
