WiFi always stops working after boot, have to unplug adapter

... and plug it back in, to get internet working again. What happens usually is that I log in, and the internet is working, but not connected. I have it set to automatically reconnect to my WiFi, but it never does. I have to manually connect it. Then a few minutes later, I see the signal icon drop to a single dot, and it stops working again, and the troubleshooter won't get past the initial problem scan, and the network settings won't load.. Until I unplug it. And plug it back in. When I unplug it, the troubleshooter finally responds and says there may be an issue with the driver, and offers me the option to "fix" it using admin privileges, but this only works temporarily. On top of that, it keeps dropping signal repeatedly ever since Windows updated today to the April update. It just did it again, while I was typing this. Please help! This is driving me up the wall!
It's a TP-Link Archer T4UHv2.

Update: It was repeatedly dropping signal earlier when I booted up the PC, so I removed the Microsoft drivers and disabled driver updates through Windows Update, then installed the TP-Link drivers. Hopefully that fixed it.
