@Purgatorium said in Trouble Connecting Duet 2 Wifi:

There is a switch in the TP-Link AX3000 router in advance wifi settings for the guest network that was disabled "Allow guests to access your local network" ...the default is off and I switched it on and I'm now able to connect to DWC. Hopefully this will help others that have a similar problem.

You should be able to register the MAC address in the router, so it's not a 'Guest'. Then you can turn off the "Allow guests to access your local network" option again. This may also fix connecting when the SSID is hidden.

As far as I'm aware, it shouldn't matter if the SSID is hidden or not, so long as the correct SSID name and password are set with M587. You could test by turning on hiding again. Though hiding your SSID may be giving you a false sense of security; see this article, which is one of many similar ones on the subject: https://techreviewadvisor.com/should-you-hide-your-wi-fi-ssid/
