Anyone can help me resolve this. I guess the problem can be afd.sys bug or the RWIN cant go above 64k/65k RWIN when the scaling factor is apply.
If i use wireshark to edit the binary for the scaling factor, is it for that specific connection or windows?
The only way scale factor show in wireshark is when i enabled timestamp then set it as 1 or 3 in registry.
If it is possible i will like to set the RWIN as a multiple of the MSS.
I have 50 mbps download and 10 mbps upload.
Firefox had the TCP window size internet explorer have but it dont have it now. I changed the autotuninglevel to see if i could get better speed, ping and lower bufferbloat then i set it at disabled and at firefox it showed 64240 but not sure when it went bad becuz i was getting the same ping as when the TCP window size was around 262144.
At the time i didn't know the browsers was showing different TCP window size.
It is the similar with chrome and brave browsers.
Autotuninglevel is restricted
