Can't see wireless unless cable plugged in

Hello,
Let me start by saying that this connection used to work, but I was not moving my laptop around and saw no point in using the wireless connection... or seeing the notification that the 802.11n radio was being turned off every time I started my machine... so I disabled the wireless connection.

When connected via Ethernet cable, my machine can see and connect to the wireless service. Viewing the properties of each connection shows two different Physical addresses, IPv4 addresses and Link-local IPv6 addresses. The rest of the information is the same. DHCP is enabled. NetBIOS over Tcpip is enabled.

If I start my machine with the Ethernet cable plugged in, then unplug it... my machine can still see the wireless service, but cannot connect to it.
If I start my machine without the Ethernet cable plugged in, my machine cannot see the wireless service.

In the Broadcom Wireless Utility, Diagnostics tab, under connection diagnostics, my machine fails the Association test (the tests that follow that one are skipped.) Under Hardware diagnostics, the utility says my machine passes the tests.

I have entered the correct WPA2-PSK password. My router firmware is up to date as is my wireless driver.

Any help would be greatly appreciated and thank you for taking the time to read this.

This happened to a friend of mine's laptop literally a few days ago. In the belkin utility, find something that says "Use this utility to connect to networks" or something of the similar. Uncheck it and apply settings. Now try. If it doesnt work, go to start > control panel > administrative tools > services > find WLAN AutoConfig > (if running, restart, if not running, start it)

 

For me it was neither of those suggestions, but thank you very much for taking the time to reply and I am sorry it took this long to get back to this.
The solution for me was to go to the device manager and uninstall Broadcom 802.11. When I restarted, the device was found, driver reinstalled... problem solved.
Not sure what was wiped out doing this that was not wiped out doing manual removal of the driver and re-installation... just happy it worked.
