I hope you are there if it's not MTU and we end up on the end of the creek...:o :cheesy:
I'll be lurking around keeping an eye on the progress; I've got email auto-notification applied to this thread....

SUCCESS!!! 
I tried setting the MTU value to 1472, 1462 and 1492 but to no avail so I gave 1454 a go and there you go; it worked!
A massive 'danke shun' to Xpenetrator and thank you to everybody that has tried to help.
Also, Xpenetrator, I noticed below the TCP Analyzer link there was a link to TCP Optimizer; is it worth using?

Woo-hoo! I'm glad to hear that! :cheesy:
Well done! So thats why the Telekom guys decided to order their hardware with such a low default setting...
You might consider to set the MTU in the router itself if it's used with more than this computer. Set the registry MTU to 1500 then. (I guess Windows will reset that to 1480 anyway...)
Yes definitely, a lot of people use it. But it looks a bit confusing since it has an overwhelming bunch of opportunities for tweaking, which can be intimidating. But it's quite easy: Just drag the slider according to your connection bandwith, then enter 1454 in the MTU box and click "optimal settings" near the bottom right, then click "Apply changes" and reboot. This way it sets your correct RWIN automatically.
This RWIN limits your connection speed, if it's set wrong (and it is!). That's why I wanted you to go to the analyzer page again: To verify whats your MTU now and to get the recommended RWIN for that MTU. Just c+p one of the proposed numbers (not the lowest 5-digit one) into Dr. TCP, apply and reboot. Or use TCP-Optimizer. Then everything should be ok.
@DMR: Thanks for backup.
