WiFi suddenly not working on Mac Studio
The WiFi on my Mac Studio has suddenly stopped working - I say suddenly because I was browsing the net fine and then it just refused to load any page.
Restarted Mac, no difference.
Rebooted router, no difference.
No VPN on.
Tried 'forgetting' the WiFi and reconnecting, no difference.
The local network is detected fine and the machine indicates it is connected with strong signal, but still no internet.
Attempting to load any site in Chrome gets This site cannot be reached etc.
Tried connecting to iPhone as hotspot - it connects but still no internet connection.
Other devices in the house including another Mac connect fine. Internet speed on those is 100mbps +.
I've tried the various suggestions here: Wifi on Macbook not working, other device… - Apple Community
but nothing is working for me. Can't ask the OP there if they managed to resolve the issue as that discussion is closed.
Grateful for any advice.
