Question: High Sierra Wifi Issue

I have a 21.5in mid 2010 iMac that I recently upgraded to High Sierra.

As other people have seemed to report, I have wifi issues suddenly. Usually when I wake it from sleep. The wifi adapter just doesnt see any networks anymore. I have tried nearly all of the solutions out there:

Turn wifi on/off

Remove the preferences

Create a new location

Change the MTU size

Change the DNS to public versions

Change energy settings - wake on network

Rebooted wifi system (its a Velop, but no other device has issues, ever)

Run wifi diagnostics

Reset NVRAM and PRAM

The only thing that brings it back is rebooting. Hardly a reasonable solution.

Will I have to downgrade this? Or adjust energy settings to never sleep?

iMac, iOS 11.2.6
