[WOW51900319] disconnects since 9.0.1

hello,

ever since patch 9.0.1 i have had disconnects everyday (about 3 and more), I have noticed recently that I am more likely to disconnect on loading screen or when my character move without my command (getting on vehicle, maw teleport in).

things I tried:
1- all addons disabled.
2- game repair.
3- winMTR with 0% packet loss.
4- i run on ethernet.
5- i updated my LAN, GPU and Chipset drivers.
6- windows up to date.

for now I will run again on no addons for the next 2 days to double check.

Edit 1:
i deleted my Cache, WTF and Interface folder
made game repair from battlenet launcher
started the game with fresh interface
still got dc

next I will try fresh windows install.

Fresh windows install with Fresh wow install and still got DC.

issue is clearly game related.

I’m experiencing the same issue; I DC when jumping into the Maw, right after the loading screen completes.

i have tried optimizing my ethernet adapter by disabling everything related to power saving, i am still getting DCs

i am the OP
i think i have finally found a fix, i have not had a DC for over 24 hours now.

disabled both windows and router firewall (i also have my pc in DMZ)
