I've put in at least 4 hours or more, trying to get this switch to connect via Wifi.   When connected to 2.4 Gz at the switch, I have a full bars of wifi.  When I then go to TP-Link it initially connects, showing a check mark, then the invariable 'No Internet Connection'.   I changed the IP address slightly, as I do have a Ring doorbell in the vicinity, yet I get the same result.  I've tried with, and without my VPN on, no change, I've reset my modem, no change.  I've taken the bezel or switch plate off, thinking it might make a difference, but again, no difference.

I'm using an Iphone 14 Prom max as my device, which is what I would have with me, if the need was to make a change while away.   I tried disabling my 5.0Gz on all devices in our home, again, same result.  I should mention on either 2.4 or 5.0 I have the full bars, and no issues at all, as it's only when I choose the TP-Link, it goes to 'no internet connection'.

Thanks for any help you can provide!
