When I try to run diagnostics using D during startup, I end up with error code -2002D. Diagnostics wont run. My Mac starts up normally, just wont run diagnostics. At other times, I end up with request to chose network, then spinning globe. I have a 2020 Intel Mac. Help?

I hope you are keeping frequent and regular backups since there are a lot more new ways to permanently lose access to the data on the internal SSD with these recent Macs due to all the hardware, software, and security changes. If you don't have a good backup, then make that backup immediately while you still can do so.

In Internet Recovery, these low negative thousands error messages (between -1000 and -7005) indicate that your provided Wi-Fi Network is inadequate in some fashion, and cannot be used (for this purpose) in its current state.
Common problems include:
Hidden Network-name
required use of a proxy server to get Internet access
required use of a login page to get Internet access
Use of a login server or certificate to get Internet access
Use of PPPoE in the Mac to get Internet access (typically only applies to DSL)
Use of Fixed IP address rather than good old DHCP
Variance of the Time by more than five minutes. if your battery has run flat, the time will likely be wonky and have to be specified with a Terminal command
Failure of Router to provide workable DNS server addresses, or providing 0.0.0.0 [may produce -2002f]
If you have an Ethernet port, you may in some cases be able to move your Mac close to the Router and connect to the Router using Ethernet.
The higher the number, the more obscure the problem.
