9. Who is your ISP (Internet Service Provider)? um
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? ie cannot display...
11. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up. um? no? there are three of us in the apartment
12. Is this a your 1st try at LW or is this a new problem with an experienced user. new- It worked in america, I came to Ireland for the summer and it hasn't worked here. I've only tried one internet connection, but its the only one easily availible. My friend has the same problem.
13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface? yeyes
14. For those using a modem/router, how is your modem/router set up...are you port forwarding or is UPnP enabled?
15. What security programs are you using (antivirus etc)? Some people might not be aware that their security suite includes a firewall McAfee and anything that came with the computer
16. What country are you living in? Sometimes there are ISPs with the same name in more than one country (eg Clearwire in the USA & also in Ireland). Ireland right now

Don't use 2 software firewalls at once...chances are they'll conflict with each other. Choose the firewall that you want to use, configure it so that it's allowing LW & disable the other firewall

It's not a good sign if the test page won't display, something may be blocking LW's default port. You could try changing ports. In LW go tools > options > advanced > firewall config. Change the listening port to 65000 (or something in the range of 49152 - 65535) > Apply > ok.

Does the appartment complex have a manager/supervisor? You could ask whether the internet connection allows p2p use. Also ask which ISP they're using.

Which version of Java are you using? There are fixes to try in the thread below. But if it's something associated with the appartment's internet setup that's stopping your connection - there might not be too much you can do.
If LW Will Not Connect

You could also try these other p2p apps & see if any of those connect.
Phex
FrostWire
BearShare

If it turns out that it's an ISP problem, have a look at these threads.
ISP's known to BLOCK or Filter p2p or specifically Limewire
Important!!!!!!! A Fix for those whose ISP's block Limewire
