Hi guys,

 

There are 5 x Acer Aspire 372-t laptops in our business and each of them have Wi-Fi issues.

 

The devices will loose WLAN connection frequently, EVENTVWR does not provide any information regarding driver failure and other events do not relate which has not helped me troubleshoot the problem. 

 

4/5 laptops have been upgraded to BIOS Version 1.11 - only one laptop remains on v1.06. That user (Laptop 1) has not reported any Wi-Fi issues (TBC) and is on an older BIOS. I wanted to roll back a users laptop from v1.11 but was met with "The version of ROM file is not newer than that of BIOS". the connection will randomly drop out, the Wi-Fi settings will be greyed out

Drivers used:

Atheros QCA61x4A - The Wi-Fi driver used is from the Acer site 

 

Scenareo #1 - Whilst user was in a meeting this morning, Laptop 4 dropped it's Wi-Fi connection. Airoplane mode was enabled and would not toggle off. WIthout rebooting, the Atheros driver was re-installed and the airoplane mode option was resolved, but no wi-fi connections were listed and the option to toggle Wifi on is greyed out. This is resolved after a reboot.

 

The user initially reported that when he resumed from sleep and powered the laptop on from home, he would not be able to see his own Wi-Fi until he fully rebooted the laptop. It then resolved itself.

    Hi,

    Try this in one of the laptops, if it works you can do the same for others as well, go to BIOS settings and click F9 Setup Defaults, save the settings by clicking F10 and exit. HTH,

    Hi, 

     

    Thank you for the suggestion. I tried to load the default settings immediately after the BIOS failed to downgrade. This does not revert any BIOS flash.

     

    I also seen people editing their BIOS updateb files on these forums which I ignored because I don't want to brick an Acer today. I have raised my request with the escalations team and sending 1/6* devices to Acer Services for assessment.

    Hi,

    No problem, pressing F9 will only revert the settings and won't downgrade the BIOS, however, you have done the right thing by sending it to Acer Service, they will sort out the problem.
