wifi not working while using power cable

Dear Forum Members,


I am using Aspire V3-371. I realized lately that I cannot connect to wifi networks while using power cable.


OS: Win 8.1 64bit

The WiFi adapter: Qualcomm Atheros QCA61x4 Wireless Network Adapter

The device driver is up to date according to the message I get when I try to update the driver from device manager.


Since some people talk about power settings causing somewhat similar problem, I checked and changed it in multiple ways - at Hi Performance/ Balance/ Saving modes, and detailed setting for WiFi network adapter either at "Maximum Performance" or "Power Saving (Hi)" In any combination of those, I cannot connect WiFi while using power cable. When I take off the power cable and run off the battery, I can reconnect to WiFi.


I have the same problem with multiple access points, so it should not be the problem with WiFi router.


Your help would be highly appreciated.

    If wifi on AC power worked before and now it doesn't, this appears to be a hardware issue. We would recommend it be serviced to check out the mainboard.

    Dear Acer-Mary,


    Thank you for your advice. I have no recollection if this trouble existed from the very beginning. Once I and my PC become ready, I will send it to repair as you suggest.
