U3419W, USB downstream ports, problem with connection

I am having similar issues to the Anonymous in this thread 

I purchased my U3419W 6 months ago back in April 2020 as WFH went on steroids. 

I have an Aukey USB extension in the rear #8-1 USB downstream port

And an ethernet USB adapter in the rear #8-2 USB downstream port

About a month ago I noticed that whenever I disconnect the USB Type-C from my work laptop (Latitude 7390) and plug back in, the 8-1 and 8-2 ports do not engage instantly. I have to unplug and replug the USB Type-C multiple times (in the laptop) for my keyboard and ethernet to kick in. Initially, I thought that it was my laptop. I ran updates but nothing changed. The same thing happens when I plug into my personal computer (Dell Precision 7520). 

Even weirder is the fact that the Aukey extension LED lights up but the ports do not work. After plugging in I can choose to wait a minute or so, the laptop switches between WiFi and ethernet (tzzzt style), so does the keyboard which also connects and disconnects a few times and if I am lucky they stay that way. Otherwise, nothing solves the issue except a restart. The whole things resets if I disconnect my USB Type-C again.

I checked the firmware on the monitor and it indicated that that it is up to date (M3B107).

At work I have the exact monitor and the same setup (keyboard in Aukey + ethernet-USB). I never had this issue happen to me at work (before the pandemic). It has become very annoying. All my remote sessions and VPNs disconnect, and I have to wait a while or restart.

In contrast, up until August the connection was instantaneous. So instantaneous that if I were to plug/unplug while in a teams meeting the meeting would not even disconnect. The transition from WiFi to ethernet used to be seamless.

I'm starting to suspect that this is not a firmware issue but rather a faulty hardware problem. 

Different USB Type-C cables yielded similar results. 

Can someone help me troubleshoot.

Thanks
