Hello,
I am also a Macbook Air 2017 user. Whenever I do the BigSur update, I am unable to use Wifi properly from then on.Although my distance to the modem is maybe 10 meters, my internet is not receiving properly and I am constantly experiencing disconnections.Also, the situation has gotten worse with the 11.2 release.
Thinking it might be a hardware issue I took it to Apple and they replaced the wifi card as well. But after BigSur update, the result is still the same.
Please solution! :/
