Looks like Xtra have a Fair Use Policy which might account for your speeds

I can't even find that policy on Xtra's site but you might want to check with them & ask.

If you can find a model for your D-Link, we might be able to help you get rid of that firewall icon but if Xtra are throttling download speeds, it's possibly not going to make much diff to your speeds. One of those links above says that they're only throttling during peak hours...have you tried downloading during off peak times? Are your speeds slow with Azureus & BitTorrent as well?
