How do I check the wireless channel in Tether? I have been looking for that for some time and can't find it. The mac address is set to phone mac address, not random.

The version of the AX90 is 1.6 the latest firmware is installed 1.1.5 Build 20210903 rel.39200 The phones are Samsung Galaxy s21 Ultra 5G REV 1.0 Andriod version 12

The wireless randomly drops to cell phones and laptops in the house, yet all streaming devices like Roku, Amazon Fire sticks and hardwired computers remain connected. What am I missing/what's going...
