VPN issues
All devices and home network are good. Signal strength is 2 bars (weak, but functional). Spouse needs to set up VPN to work from home, but even IT from the office could not get VPN to work via T-Mob...
This fixed it for me. I had problems using WireGuard VPN. I couldn't reach many sites and it was very slow.

Short version is you need to lower the “MTU” setting on your machine’s network adapter
For me on my macbook, it was the “wifi” “en0” device, either at the terminal with “sudo ifconfig en0 mtu 1350” or going to “Network Preferences > Advanced > Hardware” and manually configuring the MTU to 1350.
