[Bug 1906770] Re: Kernel 5.4.0-56 Wi-Fi does not connect

I reported bug 1907764, deemed a duplicate of this.
I've installed the latest proposed Ubuntu kernel, 5.4.0-61-generic, under AMD64 and the system is stable with my TP-Link AC-600 adapter installed. It even works!

Title:
Kernel 5.4.0-56 Wi-Fi does not connect

Status in linux package in Ubuntu:
In Progress
Status in linux source package in Focal:
Fix Committed

Bug description:
After updating to 5.4.0-56 (generic) on Mint 19.3, Wi-Fi cannot
complete connection to network with Netgear A6210 USB adapter
(Mediatek MT7612U chipset). Network manager can see available
networks, but attempting to connect to a network stalls on
"connecting" and does not complete connection. Reverting to 5.4.0-54
solves problem. I did not see this problem after updating to 5.4.0-56
on a 10-year-old Toshiba Satellite laptop (also Mint 19.3), so it
appears related to the Netgear/Mediatek hardware.
