You may have to take it to Apple to get it checked out (appointment at the genius bar).. or have your IT guys do it.
On older (non-M1/M2) MacBooks it was super simple to replace a broken network card. But I don't think that's the case in the M1/M2 versions.
Another option would be to spend $15 on amazon for a USB WiFi adaptor.. If the USB adaptor works you know its the Macbook. If it has the same problem you know it's your Wifi/Mesh.
