I tried using the Beta version but no luck there either. Im also trying to get a better (3rd party) answer about whether or not my ISP is messing with P2P traffic. If so, it is a very recent change.
Also, about Aero, I have it sitting in the task bar but I never use it just because I never think to if thats what you mean.

Try the tips here & see if it makes any difference (you could even reinstall Java 6).
Reduce the drag caused by LW

I can't find anything to suggest that KOS are traffic shaping, but I guess it's possible. Their AUP vaguely mentions bandwidth management but you've used them with no probs before:confused: Unless you changed your internet plan recently?

I have tried everything mentioned on the Reduce Drag link or it doesnt really apply to me (1000's od shared files and full queue for example) and KOS says no traffic shaping. Ive excludied just about every possibility except Vista so Im thinking of dual booting my laptop with XP sp2 and see if it is any different. Than at least I know its a Vista issue and find out whether or not I can adjust for it. Options are running out. Thanks for all the ideas though. I will keep you posted as Im sure that if this gets figured out it could help at least a few people.

That's a good idea with the XP, at least then you will know if it is Vista...
Please do keep in touch and let us know how you go...Good Luck...:rolleyes_2:

Update
 

Ok, here's the latest.

1. My ISP has confiremd no P2P blocking in any way shape or form.

2. The will not give out the username and password to access the router but they did say it has a built in firewall that could be the issue with the
Vista/P2P combo.

3. I tried dual booting with XP Pro with SP and my limewire speeds returned! However I also tried Azureus and the speed was generally the same and changed a lot.

4. Even though the speeds returned on limewire it still detected a firewall.

5. I also don think the port forwarding helped since I am now positive that my router is supporting UPnP and that the firewall being detected is the one in my modem.

Hope this helps.

The only thing is if you Port Forwarded correctly and the firewall you are seeing was the Nat firewall in your router it would disappear..

Did you know that you can log into your router by entering your ISP's IP number into the address bar in your browser....
Try logging in and have a look at the UPnP set up...
When you Port Forwarded how did you get into your router then ??
Did you go to the port forwarding site and follow these instructions ??
Make sure you don't forget the static IP part....

Sorry,
What I meant was that I have a firewall in my modem that I cant acesss. My ISP has set a password on this that they will not give out. I have tried port forwarding on my router but UpnP does work on it so it doesnt really change anything. Static IP is set also.
