Macbook Pro M1 will not connect to WiFi router after Sonoma 14. 4 update.

First try Power Cycling your WiFi router by unplugging for 30 seconds and then repluging in.

If that does not work try the following.

Select the Apple menu > System Preferences > Network. Remove your Wi-Fi connection by selecting then pressing "-.” Re-add by pressing "+" and selecting Wi-Fi from the drop-down. Press Create, then Apply.

Hey, I just upgraded my fiber internet to Eero pro 6e and ever since, my 16" M1 Pro Macbook hates everything. It'll connect to my hotspot, and even a cable service, but not my fiber internet provider... I took it to the macstore to check it out, it connected to their wifi no probs... I think it has something to do with the "6E" routers... the M1 Pro does not have the support.
