Did you check 'either' of my previous two links?
Did you try any of the suggestions?

Which model linksys & modem?

Yes I did try your suggestions and still nothing. My firewall is off and I have no idea where it's detecting the firewall. I've uninstalled and reinstalled LW. I've disabled every suggestion on the links you sent to me and and the only thing that slightly changed was the connection. Instead of 5 red bars, the smallest bar is green and the rest of them are red. But the firewall is still showing a brick wall. Also, I've disconnected and reconnected and restarted my computer. I've even changed the Listening Port to 65000, which was the suggestion.

The Linksys model is a Wireless-G Broadband Router made by Cisco Systems and model #WRT54G. The modem I have I received through Yahoo! which is a Speed Stream made by Efficient Networks. It's an Ethernet ADSL Modem...modem access code 2434912088...if this helps. I don't know what else to do. Please help!
