OpenWrt enthusiast's choice; good value, but lacks 6GHz.
Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Change the SSID and password of the 620 to the same as what your TPLink router is, unplug your tp link router, and see if the 620 satisfies your needs. You can do that via SHM. If it doesn't, turn the wifi off on the 620, connect your AXE95 to the gateway, set up ip passthrough on the 620 and turn off the wifi radios, and enjoy. My service works perfect using the 320. No issues with 39 devices currently online.
I have the same AT&T BGW. Agreed, the config panel is limited and horrible. I set mine up as a pass-through to a Firewalla Gold SE. I’m so glad I did. The Firewalla UI is so easy to use and versatile.
