Can't get 5GHz on RE815XE
Using RE815XE range extender in a OneMesh configuration with the AX11000 TP-Link router (latest firmware). I can get 2.4GHz fine, but not 5GHz. The extender is about 15 feet away from the router at this point and the signal strength for 2.4 is very strong. Is there a setting on the router or the extender that I'm missing?
I have the same issue on the 5GHz mesh like you. I'm using BE800 + RE815XE with a weekly reboot schedule on every Mon early morning to optimum the WiFi conductivities and performance in the entire week.
When the RE815XE running v1.0.4 & v1.0.5, I noticed quite many times that the 5GHz mesh connection (never happened on 2.4GHz & 6GHz) between my BE800 & RE815XE was lost (the dimmed like your screenshot) in the Mon morning. Sometimes the 5GHz band will be reconnected automatically by noon, but sometimes I need reboot my RE815XE manually then all 3 bands ok. I've reported to CS but didn't get a solution.
Until applied the latest FW v1.0.6, my RE815XE has less 5GHz mesh failure, but still happened a few times.
* I'm using Smart Connect too, 1 SSID for Smart Connect and 1 SSID for 6GHz.
