The Wi-Fi card frequently turns off and on again.
I've been dealing with this problem for several weeks and still can't find a solution. My Acer Swift 3 runs with the Ryzen 5 5500U and the MediaTek Wi-Fi 6 MT7921 chipset. It's a peculiar issue that keeps appearing. Sometimes, at least once a day, I lose Wi-Fi connection. When I try to access the settings, it shows up blank. Going through Device Manager to disable and enable the card causes the manager to crash, and in the Control Panel, the network adapter lists it as disabled with no way to turn it on. The only fix is a hard restart—pressing the power button while holding it—to switch it off and back on. After that, everything works again. I've also reinstalled the drivers multiple times, but nothing has resolved it. Any suggestions or insights would be really helpful!
It seems like one of two possibilities: either a poor driver from the brand itself or its declining state.
Visit their drivers page and check for an older version... I noticed others faced similar problems when updating to a specific driver.
