Hello All! Found the solution to fixing the network issues with the Big Sur OS Update! Been trying to troubleshoot it for a while. New to the IT world, currently a senior in college and in the process of becoming a DevOps Engineer, so this is actually my first post. But the instructions to fix it are below! Hope this helps! Resetting NVRAM and PRAM Shut Mac Down. (Full Power Off) Power Mac back on and immeditaley hold down Option, Command, R & P keys 3 Keep holding four keys until you hear the startup sound or the apple logo appears and disappears twice. (Roughly 20 seconds overall) 4. Log back in and open terminal. Type "ping google.com" to check for stable connection. 5. Enjoy having your network back!
