Realtek 8111 stuck when uploading many files.

Hi,

My LAN Ethernet is RealtekRTL8111 on Hackintosh. Mac OS 10.15.1 Catalina. Using RealtekRTL8111.kext

When I am uploading a lot of files, actually when backing up to the cloud, my internet stuck. Just infinite waiting for response for all apps, no ping.

How I can fix immediately:
1. just unplug/plug Ethernet cable;
2. Deactivate/activate Ethernet in System preferences, lan section.

For now I've created apple script that is reconnecting using "sudo /sbin/ifconfig en0 down" "sudo /sbin/ifconfig en0 up", so actually using method #2

I have no any problems when downloading, torrent works perfectly. The issue when I am uploading a lot of files. Dropbox, Backblaze etc, internet just stuck until manual reconnecting. Not every file sizes cause the problem but I think most. For now I am on a stage when uploading files around 40 MB each and internet stuck just every 0.5-2 minutes.

Btw, when uploading huge file to Wetransfer file sharing service it works fine... Some apps so not cause the problem, for example, iDrive uploading almost do not disconnect, maybe once an hour or even better.

Does anybody know why it happens and how to fix that? That happened on older Mac OS as well.

So, I've fixed that after 2 days of trying everything.
The solution was: Flashing BIOS to the newest version.
