I'm wondering if you haven't properly configured your firewall to allow LW full access. By the way Win XP has its own firewall. (Advisable not to have 2 active firewalls b/c they can interfere with each other); config instructions: Firewall configuration instructions

Do this test: Bug Report instructions & sample image Is the result True/False? If your result is false then something's partially blocking your LW. Be that a firewall or modem/router.

I hope it's not your isp provider who is causing your downlds to slow down.

Can you give us a total desciption of your set up:
1. OS version? (eg: Windows 98)
2. What firewalls you have?
3. How much ram?
4. Hard Disk space available?
5. Connection type? (eg: dialup, broadband, cable, etc.)
6. Modem & router brand name & model numbers?
7. Where are you trying to connect from (home, school, work, etc.)?
8. What version of Limewire (LW) & Java do you have? (Go to LW's menu Help>About LW...) Will show both LW & Java version.
9. Who is your isp provider?
10. Is this a your 1st try at LW or is this a new problem with an experienced user.
