can't connect to wireless network gives IP of 0 every fix I've tried hasn't worked

When I try to connect to my wireless network I get an IP address of 0.0.0.0. I'm sure I have the network key correct. I tried several things to fix this problem.

1. I tried disabling and renabling the wireless network connection.
2. I tried ipconfig /release and ipconfig /renew
3. I tried assigning a static ip and it connected, but I did not have internet access. Never assigned a static IP before so I'm not sure if I did this right. (Afterwards I switched back to dynamic ip)
4. I tried disconnecting power from wireless router and then after a minute reconnecting power.
5. I tried to right-click -> repair the connection, but it got hung up on "Renewing the ip address".

Note: I tried the laptop on another wireless network and it connected properly and worked fine. The laptop is a Dell and I disabled Dell's wlan utility and am just using the default Windows one.

Could this be a firewall issue?

Any help you could provide would be greatly appreciated.

Hi:And welcome to TSG:
Without more info,kind og hard to say.
Let's see:
Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)



In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

And ,generally for ip =0 issues,we first look at these areas:
IP Addresses all O’s
From a JohnWill post:



IP addresses of all zeros are normally caused by one of the following.

Diagnosis:
1. DHCP Service not running.
2. Duplicate IP address on the network.
3. Bad NIC card drivers.
4. Defective NIC hardware.

Resolution:
1. Check Control Panel, Administrative Tools, Services. The DHCP Client service should be Started and its Startup Type should be Automatic.
2. Turn off ALL of the computers and other network connected devices, restart (power cycle) the router, then restart all the computers and other network devices.
3. Check for upgraded drivers and/or reload the Network drivers.
4. Replace the Network Interface Card.

Quote from Johnwill

Check your Services are Started on all PCs:
COM+ Event System (for WZC issues)
Computer Browser
DHCP Client
DNS Client
Network Connections
Network Location Awareness
Remote Procedure Call (RPC)
Server
TCP/IP Netbios helper
Wireless Zero Configuration (XP wireless configurations only)
WLAN AutoConfig (Vista wireless configurations only)
Workstation

Note: You can check the services in Control Panel, Administrative Tools, Services.

All of these services should be started, and their startup type should be automatic (or perhaps manual).

If a service is not running, open it's properties and check the dependencies. Check each of the dependencies and see which one is preventing the service from running. Checking the event log is also a good idea here, there may be clues to what is failing.
Basically what was said above my post, but it will show you specifically what needs to be on Automatic and started. If all those are running as they should we can take this further to narrow down where the problem is.

Hey sorry it took me so long to get back to you.

For the services that you listed all are started except for Computer Browser when I tried to start it it gave me a message that said something like "Started then stopped services with no work to do are automatically stopped."

A couple of them are started, but manual:
Network Connections
Network Location Awareness

Here's the results of ipconfig /all:
