Having trouble connecting to the internet through my home network. I have a cable modem and a linksys hub and am using the exact ethernet card that was in my old setup. I suscribe to Time Warner Cable and have never had a problem before hooking up a new computer to the system. Any basic troubleshooting tips for me? Any help would be appreciated.

make sure you have correct ip, dns from your isp. to do this, use ipconfig /all command or post the result here.

[1.] Check to see if the ethernet card is even working in that machine by doing a loopback test. Goto CMD.EXE and C:\>ping 127.0.0.1 ; if you get a response (which you should)....
[2.] Check the wire you are using, try using another peice of CAT5/6 from a link to one of your other machines.
[3.] Since your using a 'hub'; im guessing that your ISP is using DHCP to assign multiple active broadcastable IP's (aka its not a router and doesnt use NAT; and doesnt convert your single IP into 'fake IPs' for your computers). Another thing.. (this might sound stupid); but whenever you configure a router, the general rule is to plug the 'line-in' into the LAST physical port.
[4.] This is a work-around; if all else fails... go to a machine that 'will connect/works', and bring up the net properties that include the DNS Servers, Default Gateway, Subnet Mask, and IP address. Say your one machine is '68.54.11.140', Subnet Mask: 255.255.255.128, Goto manually configure settings under TCP/IP properties, and type in the EXACT same information, except when for IP address, try something in the last octet like x.x.x.215 . Also... if your DEFAULT GATEWAY has a last octet with a value greater than 1, such as 129, 144, etc; try changing it to `1`... when its a work around, its more or less trial and error and checking settings on other machines and plugging in information with what you know from your working machines.
[5.] Another workaround to try: use a USB run from your modem or hub to the machine, instead of ethernet.
My Personal Suggestion : Buy a Router and maybe even consider buying a switch instead of a hub. This will dedicate the bandwidth instead of 'sharing' it. I use and would recommend the Cisco SOHO91 Broadband router; but a linksys router is cheaper, and also has built in switching (for some models).

first thing first...turn off your modem router(hub,switch what have u) and pc....plug in modem first and wait for the proper lights....restart hub....wait for lights......restart pc....make sure the lights on the nic and the matching ones @ your router(if available) are lit.. if you do this means that there is a physical connection and we can procede..otherwise check that the cable and nic are seated properly....
if you have both lightrs..check your ip... it should be a 192...or whatever you have previously assigned for your network....if you have a 169....then you have probs....if you have a 192 the like problem is a firewall installed on the new machine... 169 means the connection between your pc and you hub does not work..
the only right answer to "why?" is: "why not?"
