I'm beginning to understand a bit better now, and now that I think about it, all the times restarting my computer, or clearing cache and cookies has worked, has been when I got the ticking clock of doom, not the network connection error.

So what you're saying neko, is that in most cases, network connection error means it is something on the customer's side. From there, how does one isolate the problem directly? IE, what part of the firewall/antivirus, or router?
