We need to get rid of that brick wall.

Can you give us a total description of your set up:
1. Which OSX version do you have?
2. Is your OSX firewall turned on?
3. Modem & router brand name & model numbers?
4. Where are you trying to connect from (home, school, work, etc.)?
5. What version of Limewire (LW) & Java do you have? (Go to LW's menu Help>About LW...) Will show both LW & Java version.
6. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up.

7. BTW it wouldn't surprise me if your speeds are affected by your isp. Do a speed test whilst LW is not running; choose the nearest one to your location from here: http://www.t1shopper.com/tools/speedtest/#T & do a 2nd one from a different location & note the speeds: http://www.t1shopper.com/tools/speedtest/
