Today’s job was in Thornlands after a customer called to say their laptop had no internet connection.
When I arrived, the Acer Aspire laptop was not connected to Wi-Fi. It was set to connect automatically, but trying to connect manually brought up a request for the Wi-Fi password. I obtained the password from the customer and entered it, but the connection still failed. Several further attempts gave the same result.
I opened David’s Computer Repairs Tech Kit and collected a system evidence report. I then opened ChatGPT in Brave, uploaded the report and asked it to look specifically for Wi-Fi problems.
The Windows event logs contained errors involving the laptop’s MediaTek MT7921 wireless driver, along with a power-transition failure involving a Wi-Fi Direct virtual adapter. These clues pointed towards a driver or power-state problem, although the logs alone did not prove the cause.
Using the Acer support page identified during the investigation, I downloaded the Acer-supplied wireless driver. I uninstalled the existing driver, restarted the laptop and installed the downloaded replacement.
The laptop then connected successfully to the customer’s Wi-Fi. I restarted it again to check the result, and it reconnected automatically straight away without asking for the password.
Windows had also felt sluggish and occasionally unresponsive while I was working, so I gave the laptop a general tune-up. After another restart, Wi-Fi connected immediately again and the laptop felt quicker and more responsive.
The driver reinstall resolved the connection problem during the on-site checks. Repeated restarts confirmed that automatic Wi-Fi connection was working again. The Tech Kit report helped identify relevant historical errors even though the connection had started working intermittently during the investigation.
