Archer A7 trouble getting internet connection from mobile devices
After upgrading to the latest firmware I'm constantly having issues with connecting via mobile devices and tablets on both 5 and 2.4 bands. I have several other devices that work just fine with no problems such as laptops, Roku stick, 2 IP cameras, and a Ring doorbell. However if I try to connect with an Android phone (OnePlus 5t and Galaxy S9), Android tablet, or Kindle Fire, it says "Connected, No Internet". Rebooting the router doesn't seem to help, but if I log into the router portal and fiddle around with some things like changing the channel on the network or sometimes I can toggle the guest network, that will jump start things for maybe a day. But then it just happens again. I need some help here.
