Latest batch 10.15.7 (19H1519) losing wifi

I can't connect to wifi at all. Router is working as other devices are connected.

I can only connect when I do the recovery mode. And from grey the recovery mode, I've to manually enter wifi password, and then it'll bring me into next recovery mode screen where I need to enter pw again, restart and it works after.

But if I go into sleep mode, or restart, connection will be lost. Everytime, I've to reconnect using recovery mode.

I did the add different location in wifi thingy, PRAM, SMC reset. Nothing works. It's software issue as I brought it into apple store and did diagnostic.

I've MacBook Pro (Retina, Mid 2012).

I'm thinking of downgrade to the previous version (19H1517)?

hohohong,

Thanks for that info. Have you tested the steps in Start up your Mac in safe mode? That should give us some more info about there the issue is.

You can also follow Set up users, guests, and groups on Mac to set up a new user and see if you get the same behavior there.

Let us know how that goes.
