Set your MTU on Router 1472 test again those from up there then apply again results here!

I think we're already on 1472

open command prompt elevated (Run As Administrator)

add these:

netsh int ipv4 set subinterface "Local Area Connection" mtu=1472 store=persistent

netsh int ipv4 set subinterface "Wireless Network Connection" mtu=1472 store=persistent

HIT ENTER after each one added !


Another formula you should try is here :

try lowering MTU with 2 bytes until you get >> RWIN is a multiple of MSS

netsh int ipv4 set subinterface "Local Area Connection" mtu=1472 store=persistent

netsh int ipv4 set subinterface "Wireless Network Connection" mtu=1472 store=persistent

ex:

netsh int ipv4 set subinterface "Local Area Connection" mtu=1470 store=persistent
netsh int ipv4 set subinterface "Local Area Connection" mtu=1468 store=persistent
netsh int ipv4 set subinterface "Local Area Connection" mtu=1466 store=persistent

so on , until you see in speedguide analyzer RWIN is a multiple of MSS

look at mine, I am on Orange PPP wireless connection !

I like German order so... I use Restricted mode
You can try to use this too : netsh int tcp set global autotuninglevel=restricted

for best results over internet, you should use Firefox 31
good luck !

Thanks KEiGHT!
