big sur wifi problems
I bought an iMac27 refurbished (Apple) early Jan2021--initially had no problems with wifi (had moved up from iMac21)--it came loaded with Big Sur--in last 3 months it has been slipping off my very strong router (in our apt--private) and going onto the public, much slower wifi---it doesn't seem to want to hold to initial connection and choses , on its own, to go looking for another connection--
iMac 27″, macOS 11.4
