Acer aspire E5-576 laptop with Qualcomm Atheros QCA9377 WLAN Wireless Network Adapter

Wopo

Hi. I had lots of problems with my Acer aspire E5-576 laptop with Qualcomm Atheros QCA9377 Wireless Network Adapter

Currently I have 2 problems:

1. After 2 years of using it I am no longer able to connect to Wi-Fi (any Wi-fi). The wi-fi networks are detected but after providing password, there is no possibility to connect to a network.

Wi-fi networks that aren't protected with password also can not be accessed.

2. After 2,5 years of using this laptop I am no longer able to share the internet from this laptop with other devices by creating a hotspot. This was possible until a few weeks ago but no longer is possible.

I have checked the drivers updates and according to my laptop all drivers are up to date. Nevertheless I have downloaded a buch of older and newer drivers, installed them and off course it did not solve the problem.

The error I receive when trying to share the internet is: You can't share this internet connection as the internet network can not be accessed (translated from polish, so english error may sound a bt different). This error is incorrect in my opinion as I am connected to the internet via external portable modem.

I am still able to connect to the internet using cable internet or USB mobile internet device but no longer can access any wi-fi protected or not.

No longer able to create internet hotspot and share it from the laptop.

The bottom cover & battery must removed to access wlan m.2 module and antenna connections. Try re-seating the wlan and its two antenna coaxial cable connections to help clean the contacts. Be careful when removing coax connectors as they are very fragile. if this doesn't resolve the issue, then the antenna cable probably has a broken wire in the hinge area from wear and tear of opening and closing the lid too much. Replacing the cable is a bigger task that requires removing the screen bezel and hinge cover since the antenna is mounted in the screen lid.
