Internet Randomly Disconnects: Ethernet Network Adapter Keeps Disconnecting

My internet keeps randomly disconnecting throughout the day. Its a Dell (Windows 10Pro 22H2 - Dell Precision 5770) with Network Adapter: Realtek USB Gbe Family Controller Ethernet. I tried these steps below, no resolution yet:

One thing I noticed, everytime the internet randomly disconnects, I go to Device Manager, and notice the Realtek Network Adapter has totally disappeared from the list (with no option to reenable, even after finding it in Hidden devices).

I have to go through these two steps in this order to bring back internet.

1. Restart Computer
   
2. and then Restart Modem Router. ( I do restart modem by unplugging/plugging back in).
   

If the ethernet disconnects, Restarting the Modem won't work. Neither will Restarting Computer work. It has two be those two steps above in that specific order. I'm curious if having this resolution path, to understand why ethernet adapter disappears. If you can help target or specify why its occurring?

Already attempted this: and the problem still continues

1. Updated Dell Drivers
   
2. Windows Update
   
3. Network Adapter Troubleshooter
   
   
   
4. (a) Network Reset and (b) tried manually uninstalling/reinstalling network drivers separately
   
   
   
5. Tried manually downloading the software drivers at Realtek website Oops!
   
6. Replace cable just in case, but the other computer in home does not have internet randomly disconnect
   
7. Tried:
   

1. Disable these three in Device Manager: (a) Energy Efficient Internet (b) Green Ethernet (c) Wake on Magic Packet
   

I use the modem with another computer, and no issues whatsoever, until I got a new computer.

Note: this is different from previous question, since its looking at a problem/diagnosis path, rather power management settings.
