Can Connect to Guest Wifi but not Regular Wifi

Here's a weird problem, my MB Pro can't connect to my home network via wifi. All my other devices can so I assume it's to do with the laptop. The laptop can connect to the guest network wifi on the same base stations, but not my home network.

I've tried deleting the home network ssid from Network Preferences and also tried rebooting.

Any idea what might be causing this?

Edit: PS, the first time I tried rebooting it worked and connected, but rebooting doesn't work anymore.

 

I had rebooted the router base station but hadn't thought to reboot the bridge base station. That worked. Thanks.
