...I tried to go through the internet connection wizard and get it set up, but it didn't work. ...
Before you use IE, Netscape, Foxfire or any other browser...you must first have a valid connection to the internet. And before you can have a valid connection to the internet you must connect to your local area network, whatever form it takes. (Believe this would be true even if you ONLY have ONE PC connected directly to the DSL and/or CableModem.)
One poster mentioned IPCONFIG from an MSDOS Window. You can also use
IPCONFIG /ALL <-can be lowercase, uppercase here only for emphasis
w/ the /all parm you can see the IP addresses of your DNS servers as well as more information, though IPCONFIG by itself will show your Connection-specific DNS Suffix; IP Address; Subnet Mask and Default Gateway.
With (w/) the /all parm you should see DHCP Enabled and Autoconfiguration Enabled if you don't this may be your problem.
Start / Settings / Control Panel / Network and Dial-up Connections you should see "Local Area Connection" icon, if you don't you have not configured your computer to connect to the network in your house (i.e through hubs and/or routers, not the DSL or CableModem Routers)
Right Mouse Click on the "Local Area Connection" icon; select Properties; select Internet Protocol (TCP/IP) / Properties - make sure "Obtain an IP address automatically" is selected.
To get to an MSDOS Window:
Start / Programs / Accessories / Command Prompt - should work for most versions of Windows Operating Systems.
