-Could be a faulty router. Try calling Linksys support.
-Check the DHCP settings on your router
-Check that you're not filtering by MAC address
-See if your router is getting an IP address from the ISP. The PC might not be getting a 192.168... address from the router (as the ISP tech support guy said), but your router should be getting an IP address from the ISP.
Hopefully this helps somewhat, but without more info, it's hard to say (though you've given more info than a lot of people do).

Maybe you have a DNS issue on that PC. Try configuring your PC to use OpenDNS.
https://www.opendns.com/homenetwork/start/device/windows-xp
You only need to follow the first page of instructions. Don't worry about page two that asks you to create an OpenDNS account. It is not necessary.

1 - Connect to the router and go to the status section
2 - Find the IP address and subnet mask. This is the IP address that your ISP is assigning to your router, and is your address that the internet can see. Write down that IP and subnet.
3 - Disconnect and disable wireless, disconnect from the router and plug ethernet cable directly into the modem.
4 - Change your settings on your PC so that you no longer automatically obtain your IP. Instead, change the IP and subnet to match the addresses you obtained in step 2.
5 - Check to see if you have the right IP using ipconfig.
6 - Check your internet connection by typing in http://74.125.45.147 into your internet browser (this is an IP address for google.com) and this will allow you to connect to the website without using the DNS server.
Let me know how it goes!

I have wireless connectivity but no wired connectivity. Support guy said my PC could not obtain an IP address
I changed out all ethernet cables several times.
Brand new Linksys WRT160N router.
Cable internet installed yesterday.
My PC and laptop both worked at my old house (wired and wirelessly)
Is it my modem? Is there a problem with my IP?
Support guy of ISP gave up on me! lol
PC set to automatically obtain IP.

A few things to consider (can't give a really great answer here without being able to really troubleshoot)-Could be a faulty router. Try calling Linksys support.
-Check the DHCP settings on your router
-Check that you're not filtering by MAC address
-See if your router is getting an IP address from the ISP. The PC might not be getting a 192.168... address from the router (as the ISP tech support guy said), but your router should be getting an IP address from the ISP.

- I know the router is good b/c plugging both laptop and PC into the modem directly yields the same result as the wired connection on the router.
- whats the best way to see if the PC is getting an IP address?
thnx

It looks like your PC is getting an IP address from your Linksys router (you said so, and you can access the router). Can you not browse the web, is that the main problem?Maybe you have a DNS issue on that PC. Try configuring your PC to use OpenDNS.

open dns did not iimprove the situation. It actually made it worse. I have limited connectivity now, and changing to open dns took that away. I since reset the settings for the connection.

Is it a problem with your home network or your internet connection? Can your desktop and laptop communicate with each other? Can you access your modem? Or is everything working except your internet connection? Go to Run and type in cmd.exe. Then type "ping 192.168.1.1" This is the usual IP address for a modem. If it works, the problem is either your cable internet or your modem. If it doesn't work, either you have a weird modem and should refer to the instruction manual for it to find its IP address or the problem is with your home network. If the problem is your home network, find the IP address for your router and try pinging that. If it works, the problem is between your router and your modem. If it doesn't work, the problem is between your computer and your router. That's all the advice I can give you without further information.

- Fact Refuted
192.168.1.1 is the IP address of the router, not the modem.

Well, I instructed martizpan to check his manuals to make sure he is using the right IP address. All of the modems I've seen use 192.168.1.1 as their IP address.

Cable modems have two IP addresses.
* a customer-side IP address used on the ethernet/USB socket to which the user connects.
* an ISP-side IP address used on the CATV socket to which the ISP's network connects.
The customer-side IP address of a cable modem is normally 192.168.100.1.
But it will always be 192.168.100.xx
xx is in the range 2-254
The cable modem IP address 192.168.100.1 is not in the same sub-net as the user's PC.

You said you can connect to the router. Try this:1 - Connect to the router and go to the status section
2 - Find the IP address and subnet mask. This is the IP address that your ISP is assigning to your router, and is your address that the internet can see. Write down that IP and subnet.
3 - Disconnect and disable wireless, disconnect from the router and plug ethernet cable directly into the modem.

If you still do not have net access:
Click: Start, Run, and type in - CMD
At the command prompt type, ipconfig /release
Wait till you display:
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 0.0.0.0
Subnet Mask . . . . . . . . . . . : 0.0.0.0

Test Connection.
Come back and let me know how this goes, if you still have no net access, we have a couple more steps to try.
I'm sure you did it correctly, just humor me :)
After installation... you would have accessed the Router’s Web-Based setup page by entering
192.168.1.1 into the (URL)address bar of your web browser.
If you did not complete this crucial step, let me know and I will walk you through it.
Connect the Broadband modem to the computer using an Ethernet cable without the router installed and make sure that the Internet connection is active.
Can you connect? If so, hook back up through the router.
If not, we're looking under the wrong rock and we need to start over.
Assuming you can connect (I'll go on to save some time).
You said you accessed the setup page... did you
Under Internet Connection Type field and select Automatic Configuration - DHCP.
Click MAC Address Clone. Select Enable and click Clone Your PC’s MAC.
Click Status. Check the value of the Internet IP Address. If the Internet IP Address has numbers, this means the router has been properly configured.
You should now be able to access the Internet. If you’re not online, perform a power cycle to synchronize the router with the modem.
Proper Power Cycling
Step 1:
Shutdown the computer.
Step 2:
Unplug the router’s power cable.
Step 3:
Unplug the Broadband modem’s power cable and wait for 30 seconds.
Step 4:
Plug in the Broadband modem’s power cable and wait for its lights to appear stable.
Step 5:
Plug in the router's power cable once the modem’s lights appear stable.
Step 6:
Power on the computer on and test the Internet connection.
