I just got a T9E a few days ago and am having the same problem in macOS, but only after waking from sleep. Speed test shows 176 mbps, but after sleep it falls to between 2 and 5 mbps. Restarting fixes the issue until the next time the PC sleeps.

In my case, the card is detected OOB in catalina 10.15.2 BUT i have 2 issues:

1. Able to connect to 5GHz network, but max speed is less than 1mbps.
2. Unable to connect to 2.4GHz network - keeps asking for wpa2 password.

So frustrating.
