Wifi Router and Hub Online but cant connect devices

[BlingGIrl]

I have had my wifi router and hub for almost two years working flawlessly. All of a sudden a few days ago it sporadically disconnected my computers.  Unplugged/ restated, worked fine for a day now it won't connect anything. I've u plugged/restareted, restored network from app. I have tried everything but can't connect my devices.

My internet speed is blazing fast. My wifi router and wifi hub are both online with great mesh connection.

I work from home and am to the point that I will have to move my computer and hard wire it to my modem to be able to work this morning if I can't figure this out.

Have you tried a factory reset of your network (https://support.google.com/googlenest/answer/6246619?hl=en), then set it up from scratch (https://support.google.com/googlenest/answer/9548301?hl=en) with the Google Home app? If you make sure to use the same name (SSID) and password for the network, devices should reconnect by themselves.
