You need to provide more information.
Did the system ever connect? If so, what happened since the last time it worked (new hw, sw, virus, error, etc)?
Can you ping?
Are there other systems in the house? If so, do they get a signal?
What happens when you direct connect to the modem?
Did the system ever connect? - Yes
What happened since the last time it worked - It's coming up with a webpage displaying "Server Runtime Error". no new HW, SW, VIRUS?.
Can you ping: Haven't tried, but I can type in CMD "ipconfig /all"
Are there other systems in the house? - Yes there are 3 computers currently in the house. 2/3 have tried to connect to the internet
If so, do they get a signal? - Signal? it's not a wireless connection?

Is that information sufficient?
