In the last couple of weeks for some reason my devices like Iphone, IPads, Smart TVs, Firesticks, Windows 10 and Windows 11 laptops are able to connect to the Archer 6000(US), BUT the connection says it has no internet connection.  This is happening once a day with at least one device.  The only solution is to log into the router and I select reboot.  After the reboot, everything is good until the next device has an issue.

What can be causing this "recent" issue?
