i225-V adapter's internet has stopped once files are being download with speed >= 10Mib/s

[SADAFD1111]

hi 

I have the following problem:

THE PROBLEM:

All is cool with the ethernet adapter which is on ROG STRIX B550-A GAMING motherboard UNTIL I start downloading something from internet with speed 10MiB/s

CURRENT FIX: 

1. I reinstall the driver

2. I do network reset in Win10

3. and leave PC whole night with power disconnected

On the morning after this procedure it's working again.

I tried also:

- ipconfig /flushdns

- ipconfig /renew

- ipconfig /release

- I tried using update NVM tool  => but I get error 

- I also tried setting receiving and transmitting buffers to 2048 instead of their defaults 1024

Notes:

- I have 100 Mbps Internet from ISP

- I have gigabit router

- I use newest driver from Asus site: 1.0.2.14
- In the morning all hardware testing is green except NVM Integrity Status
