okay this is what i can tell you about what i know, although i dont know much about computers....

1. Windows Vista I have.
2. firewalls unsure of, if you can tell me how to figure that out i can look into it, but i think i looked into it and changed it right, i just dont know what the firewalls are, its a dell computer, it was a $500 package desktop deal thats brand new, so its pretty basic with everything it came with. Also i haven't set up the mcAfee security center on it, it also has 1GB.
3. ram unsure of how to find
4. 1GB
5 and 6. cable modem, brand is Surfboard, model number-SB4100
7. connecting from apartment, with router, router is D-link, number 802.11G/2.4GHZ, its wireless but i dont use it as wireless, the ethernet cords are connected.
8.LW version is 4.12 i think the basic, and java unsure of
9. ISP is road runner here in milwaukee, cable modem
10. it says your test worked.
11. i have another computer next to this one that is hooked up to the router and that computer works fine, but i dont have lime wire hooked up to it cuz its not my computer, its my roommates
