Replaced an old AC1750 with this AX3000 (AX55).  Very disappointed so far.

For opening some internet sites via WiFi (2.4 or 5GHz), the sites will take 45 seconds to a minute to display the site.  But if I switch to my cellular network and open the same sites, they open immediately.

I have network software to check on what is happening and what I seem to be seeing when this happens under the WiFi tab is the inability to get an external IP, which has an ever rotating circle (as below).

Any ideas on how this can be fixed?
