  9. Hi There. Thanks for the post. I've just recently moved to Ho Chi Minh and signed up for a 15mbps connection. While its great for local sites, youtube, facebook etc are megga slow. Is this cable issue at fault?
    Any tips for increasing speed.

  10. Hi John,

    15mbps is a fast connection and I do not think you should face slower loading of youtube or facebook. Please ensure your firewall settings are configured properly. If you still find the same problem, I suggest you to contact your ISP and ask the reason for it. BTW are you facing the issue in just one computer or in all computer connecte3d to the network ?
