Some ISP’s buffer you tuber steaming to download to a cache file on their server
If you set the relevant IP range in the Windows Firewall, to block that it could improve the performance as it then streams the video from the YouTube server directly
as administrator open the CMD window and paste
netsh advfirewall firewall add rule name=”TWCYouTubeFIX” dir=in action=block remoteip=173.194.55.0/24,206.111.0.0/16 enable=yes
Now reboot the system and try to access YouTube and see if it works better.
It might take time to start because of IP blocking. But once it does it might be faster.
To remove this rule, just type the following and hit Enter:
netsh advfirewall firewall delete rule name=”TWCYouTubeFIX”
