r6200v2 2GHz connection issue

I recently shut off wifi broadcasting for 2 GHz and 5 GHz on my TG1672 all in one from TWC so I can use my netgear router as the sole wifi router. I got it all hooked up and connected my smartphone which works fine off of both the 2 GHz and 5 GHz bands. I connected the router to my HP all in one desktop via ethernet and it worked fine as well that way. The problem is when I go to connect my desktop to the router's 2 GHz band (doesn't support 5 GHz band) and it will connect fine but will have the yellow triangle and say unidentified network, connected, secured, no internet access. I tried rebooting the router and changing the SSID and Password for the network and neither helped.

Can anyone tell me why I can't get internet from the connection on the all in one desktop when it works fine on my phone?
