A7000 traffic stops for 30 seconds every 2-3 minutes

This started following a Windows Update about two weeks ago. No other hardware was changed.

ThinkPad X1 Tablet (Win 10 Pro 22H2) > USB3 Port Replicator > USB3 cable > A7000 > Router

This configuration has worked flawlessly since I bought the A7000.

Following anywhere from 2-20 minutes of normal operation, traffic on the Adapter just stops. Browsers hang, media ceases to play. Browers might show DNS Not Resolved or a DISCONNECTED error message. If I do nothing, it all goes back to normal after 20-45 seconds. This happens whether I'm accessing the internet or something on my home network. MS Word might go into "not responding" when trying to open or save a file on the NAS. Again, 30 seconds later, all is well. I can play media stored on NAS. It'll run anywhere from 2-20 minutes before stopping. I have to restart the player to get back where I was. 

I have power-cycled the A7000, reinstalled standalone drivers from scratch, changed DNS servers and combed through Event Viewer logs looking for something related to the issue. FWIW, I can switch to the X1's internal WiFi adapter and it performs without this issue, though it doesn't receive the same signal level as the AC1900 USB 3.0 WiFi Adapter (A7000) 

Thanks for any help.
