New laptop and can't connect

[clappsa]

Hello all. I recently got a new Gateway and am using the same router and same Zone Alarm firewall as I was using with my old Dell. The only difference (that my extremely amateur eyes can tell) is that the Gateway is Vista and the Dell was XP. Anyhow, it never connects more than a single bar and I'm at the end of my rope here. Hopefully you guys can help me. Here are my specs:

1. Windows Vista
2. Zone Alarm
3. 2 GB of RAM
4. 101 GB of free hard drive
5. DSL connection
6. Modem is a Westell 2200 and router is Belkin Wireless G Plus Router model F5D7321-4
7. Trying to connect from my house although I have tried from apartments, hotels, etc. Can't connect anywhere.
8. Limewire version is 4.14.8 and Java is 1.6.0_02
9. Bellsouth
10. The test worked.
11. I am connecting wirelessly with a laptop and a desktop is connected by cable to the router
12. I used Limewire extensively with my previous laptop and the desktop works fine as well.
13. There is a brick wall in limewire
14. UPnP is enabled on the router.
15. I am using Zone Alarm for the firewall, as well as AVG antivirus, Ad-Aware, Spyware Blaster, and Spybot Search and Destroy. All of these were on the old laptop that had no difficulties.
16. USA

I would greatly appreciate any help anyone can give me. Limewire has been given permission in Zone Alarm and it connects the first bar but never goes beyond that. Thanks in advance.
