changing the wireless name (SSID) and channel also helps

make sure you install/download the driver of the router that you have. Know the ID and password for your router. Then go to your network connections and make sure you add that router and make sure your the administrator of that user account. Hope this helped

kgreen22,

Did you get any IP address from DHCP ? what IP address do you get? check with
RUN-->CMD-->ipconfig

If you are getting something like 169.x.x.x you computer is not configured with IP address and you need to get it by either DHCP or manually.
Internet Router

you better give ur own ip address but be sure u give the ip address of same class which ur room mate has

Not sure this will work for you but is worth a try.
I copied this instruction some time ago and tried it but it seems my network card was faulty.
Try this and see if it will work.

For wireless connections:

1. Hold the Windows key and press the R key, type services.msc and press Enter or click OK. This should open a new window - services local.
2. Look for Wireless Zero Configuration on the list in the right pane. The list is alphabetical, so you should be able to locate it maybe third from the bottom.
3. Double-click it to open it.
4. Click on the STOP button to stop it (lower left). If it is not highlighted or is grayed out, then the service is stopped. (it should also say that the SERVICE STATUS is stopped).
5. Look for STARTUP TYPE drop-down menu. Change it from AUTOMATIC to DISABLED. then click on APPLY (lower right).
6. Then just change it right back from disabled to automatic and click on apply again.
7. Click on START button (right beside the STOP button) on the same window to start the service.

--- We are essentially restarting the windows wireless service. What we did just turned it off and on again ---

8. Close the services local window.
9. Go to Start and then Control Panel. Network Connections. If you don't see Wireless Network Connections or Local Area Connection after opening Network Connections, kindly look for Network Connections again (it maybe on the lower right).

--- We need to be on the page where you have the wireless network connections icon. ---

11. Right-click on the icon for Wireless Network Connections then left-click on Properties.
12. You should have several tabs. Click on Wireless Network Connections tab (near the top of the window).
13. Make sure you have a checkmark on where it says, "Use windows to configure your wireless connections..." or something like that.

--- Before going into the next step. Kindly make sure first that you have the following CORRECT information: (1) your own SSID; (2) Network key (if you have one) - WEP or WPA or whichever encryption you are using. If you don't know these information, kindly secure these information first or better yet, try calling your router manufacturer to help you out on this ---

14. Then on the list that shows on the same window, remove everything on the list. That list shows all the wireless networks that you have been connected to before.

--- Don't worry about deleting it. The next time that you connect to the wireless network, it will be automatically added back into this list ---

15. Once everything is removed. Kindly close the window.
16. Go back to where you have the Wireless Network Connections icon again.
17. Right-click again the icon and left-click on View Wireless Network Connections.
18. If your wireless router is broadcasting your SSID, then you should be able to see it on the list of wireless network(s) that will appear on the screen.
19. Select your SSID and hit Connect.
20. It should be asking for your network key. Type it in. In might ask you to confirm the network key. Just type it in again.
21. It will attempt to connect it. And you will get a notification that you are connected.
22. Once you are connected, go back to the window where you have the Wireless Network Connections icon we were working on before.
23. That icon should say that it is connected.
24. Double-click it. It should open a new window.
25. You should have a General tab and a Support tab.
26. General tab should say it is connected.
27. Click on the Support tab.
28. Now confirm if your IP Address says 192.168.x.x. where x can represent any number. Example: 192.168.0.100
29. If you have these confirmed. Kindly try to see if you can now get into the internet or into your network.

I'm not taking credit for this, I'm just passing out this instruction/information to see if this will work for you.

Ok, I just had this problem and here was the fix:

Disable the firewall
Go to where you can manually put in an IP address and make sure "obtain IP automatically" is checked. This works. After the router allows an IP address to be located, then enable the firewall again.

That is also very important to disable the Firewall on your computer.
Thanks for the info.
