OK, MPU experts, I need some major help here. This is kind of a long setup, so bear with me.
I have a 2020 MacBook Air with the M1 chip. It’s running macOS Monterey (12.3.1). At home and everywhere else, it connects to Wi-Fi just fine.
However, when I take it to my office, it will recognize all the various Wi-Fi networks around, but it will not connect to the workplace’s network.
Now, here’s the interesting part. In my office I have an older Mac mini that is running the same OS, and it connects to the chosen Wi-Fi network just fine. In another part of my office I have a 2013 MacBook Pro running Catalina that also connects just fine.
I have done all the usual suggestions found in various web sites: rebooted, “forgot” the network and selected it again, deleted various preference files, reset PRAM and NVRAM, etc. I’ve talked to our IT folks, and although they don’t support Macs they have gamely tried to help. They are as puzzled as I am.
Resetting the router is probably not the solution because we’re a HUGE wireless network covering four buildings made up of 23 stories. Plus, since every other Apple device I own connects with no problem, I doubt it’s the router or any of the other nearby wireless points. Many people who work near me also connect their Apple devices to our network with no problem. Thus, it seems to be something about this particular MacBook Air.
A couple of other notes. I have copied all the network settings from the Macs that do connect and plugged them into the errant MacBook Air. No luck. The message I get is simply that the network can’t be joined. This isn’t an issue of usernames or passwords. I don’t even get to that point. It just seems to try to connect for a minute or two and says it can’t be done.
I also created a new administrator account to see if I could connect using that user account. Nope.
So, I’m really confounded about all this. Does anyone have any deep ideas that might help get this laptop into a more cooperative mode? I suppose I could always do a “nuke and pave,” but that is certainly the last thing I want to have to go through.
Thank you all for your ideas. I appreciate any insights you might have, even if I’ve already thought of it.
