This problem has been reported by other users.  Earliest that I've found on this forum is from 2020.  I believe that I've reported this problem to tech support back in 2021 when reporting problem with its drivers.

The unit will work fine on the standard USB-A port on a PC or laptop.

However, when connected to the USB-A 3.0 port it will repeatedly loose it's 5G connection (as well as the standard 4G).  Once in a while, it will hold the WiFi connection but only on rare occasions.  And when it does, the thru-put speed is horribly slow.

NOTE: edited on 2022-09-26 for mistake naming USB-A  3.0 port as USB-C port.  Realized error after seeing feedback/reply to post.
