One thing I can't make sense of is why your DHCP Client is disabled from the log you posted, but I have no idea why this would only impact on WPA.. you should be having the same problem with wired (unless a static IP was assigned) or WEP. Still, it should be enabled, please can you:

• Right click on My Computer on the start menu or desktop, and go to Manage.
• In the left hand pane, double click on Services (found under Services and Applications).
• Scroll down to DHCP Client which is suspect is disabled by the looks of it.
• Double click on it, change the Startup type to Automatic and click Start

Try again? and then post another network test if problems persist.

Was it started? it's not showing as running here.

If not, try to start it, and then take a look at the Event Viewer (still in Computer Management), under System to see if there are any errors?

It's possible. That doesn't look like an error?

It should be around the time you started the DHCP client or when the PC was first started. It will appear as an error if there was a problem starting the service.

It might be easier for you to just save the log (under Action > Save all events as) and upload it here if you can't see it.

DJ, I'll try to be more clear,

It may be nothing, but I need to find out why the "DHCP Client" service was not listed in your Wireless Test. Without this service, you'll be able to connect to the router, but you won't be able to see anything else.

You said that the service was set to automatic, was it started?

In Event Viewer, under "System", you'll see a lot of "Information" events with a little (i) icon to the left. If there was a problem starting the DHCP service, it will appear as a "Warning" or "Error". When you double click on it, it will say something along the lines of "Could not start the DHCP Client Service on local computer", along with further information as to why.

Ahh, OK,

Can you also check the same with the "TCP/IP NetBIOS Helper" service, make sure it's set to Automatic and Started. Then, take a look at the following Microsoft article: http://support.microsoft.com/kb/915162

Then,

• Go to Start > Control Panel > Network Connections, right click on your wireless connection and go to Properties.
• Under "This connection uses the following items", select Internet Protocol TCP/IP and then Properties.
• Click Advanced > WINS tab, and set your "NetBIOS" setting to Default.
• Click OK > OK > Close.
  .
• Go back to Control Panel, and click System > Hardware tab, Device Manager.
• Click on View > Show hidden devices.
• Under the category of "Non-Plug and Play Drivers", and double click on AFD Networking Support Environment
• Under "Device usage", make sure this device is enabled.

Now go back to services and see if your able to start the DHCP Client once again (if it hasn't already started from the first reboot). In Event Viewer, a successful start should no longer start as an error, instead a informational event along the lines of "The DHCP Client service entered the running state". If you get this far, then:

• Go to Start > Run, and type in cmd
• From the command window that appears, type in: netsh interface reset all
• Type in exit to quit the command window, and try to connect via WPA once again
