AC1200 No 5ghz

I just purchased the GLSF1200 ac1200. It will not connect to internet 5ghz network, only 2.4ghz. It will eventually connect 5ghz SSID but does not connect to internet. I have upgraded firmware and rebooted.

So 2.4G connects and you have Internet?

Is this a hotel network? or your own network.

When this happends, pls try to ping on the router and on your pc to identify which node is the problem.
