So I bought a TP-Link Wifi 6 AX3000 to connect to my ViaSat Modem/Router.  The Viasat modem/router is in my garage and I ran 300' direct bury CAT6 cable to my house and connected to my TP-Link router.  Both the wifi and internet lights on the router are green but when I connect to the router with my iPhone it says "no internet connection".  The Viasat modem/router in the garage works fine.  I can connect to the 2.5 Ghz signal from the house and the 5 Ghz signal in the garage.  I then took the TP-Link router to the garage and connected it with the CAT5 cable that came with the TP-Link (to eliminate the cable being the issue) and have the same issue.  Viasat is telling me that it should be "plug and play" with their modem/router.  I've unplugged both and went through the rebooting sequence several times.  Any ideas out there?
