My connection was working fine for many months. Now, this weekend it stopped working. No updates performed and all steps found in the forum do not appear to help.

1. OS version? (eg: Windows 98)
Windows XP, SP2

2. What firewalls you have?
Linksys BEFSX41

3. How much ram?
1GB

4. Hard Disk space available?
122 GB

5. Connection type? (eg: dialup, broadband, cable, etc.)
Cable

6. Modem & router brand name & model numbers?
modem: Motorola SB4220 Surfboard Cable Modem
Router: Linksys BEFSX41

7. Where are you trying to connect from (house, appartment complex, school, student accomodation, work, etc.)?
House

8. What version of LimeWire (LW) & Java do you have? (Go to LW's menu Help>About LW...) Will show both LW & Java version.
Just upgraded to LW 4.12.11 (to see if that would help). Java 1.5.0_06

9. Who is your ISP provider (Internet Service Provider)?
Comcast

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?
I get 'Your test worked!'

11. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up.
I have 4 computers going through my router.

12. Is this a your 1st try at LW or is this a new problem with an experienced user.
I have been using LW successfully for many, many months.

13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface?
Yes.

Any guidance would be appreciated. Thanks!
