[Firewall?] Aldoria's Connection Problem (5 green bars but slow downloads)

[Aldoria]

1. OS version?
Windows Vista, "hacked" Administrator account (more access than Admin). (How do I Enable the Windows Vista Administrator Account? for more information)

2. What firewalls you have?
Just Windows Firewall, I've tried turning it off, and tried keeping it on. I've tried allowing Limewire, and not allowing it.

3. How much ram?
2GB

4. Hard Disk space available?
199GB Free, 298GB Total

5. Connection type?
DSL

6. Modem & router brand name & model numbers?
SIEMENS Gigaset SE567

7. Where are you trying to connect from:
Home.

8. What version of LimeWire (LW) & Java do you have?
Limewire 4.18.3 & Java 1.6.0_02

9. Who is your ISP?
Aliant

10. Do this simple test for us. Using your browser go here: http://www3.limewire.com:6346/ The page should say 'Your test worked!'. What happens when you go there?
It says "Your test worked!!"

11. Are you sharing the connection with other computers or p2p sharing programs?
No.

12. Is this a your 1st try at LW or is this a new problem with an experienced user.
I've been using Limewire for years and never had this happen before. This happened a few months ago, and I've been to lazy to fix it.

13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface?
Yes, but I've even turned off my firewall, and allowed Limewire, and it's still there. Weird.

14. For those using a modem/router, how is your modem/router set up...are you port forwarding or is UPnP enabled?
UPnP is enabled.

15. What security programs are you using (antivirus etc)?
Norton Antivirus

16. What country are you living in?
Canada, New Brunswick


Additional Information: I know it says I have a Firewall on the Limewire, but I've tried turning off my firewall. I think Windows Firewall is the only one I have, but if anyone knows of a Norton Firewall I may have, could someone tell me how to access it and disable it? (Only if you don't see another problem above)
Also, I've alredy re-installed LimeWire.
Oh yeah, I've also got all 5 bars green, but my download speed is still the *****. It takes me forever to search for stuff, longer to download, and that's only IF it will download.
