How to fix :Microsoft Vista connects to wireless network then says unidentified network

Have you ever got the problem with Vista when a few days ago you managed to connect to a wireless network(or Wi-Fi) properly but recently if you try to connect again it says to you "Connected to Unidentified Network(wireless name)" ?
I got this problem a few days ago and tried a google search for a solution... but nothing came up. Then I did the following steps out of frustration, and everything worked out perfectly and I'm back to wireless internet again:
STEP 1: Well, I think since you are gonna restart the computer, close and save all work.
STEP 2: Open the Network Connections (I usually open this page by first accessing Network and Sharing Center, then clicking of the link Manage Network Connections).
STEP 3: Rights click on the "Wireless Network Connection" icon and select "Properties".
STEP 4: Click on the button "Configure".
STEP 5: Click on the tab "Driver" and click on "Uninstall".
STEP 6: This is an important step. MAKE SURE THE CHECKBOX "Delete to driver software for this device" IS UNCHECKED!
STEP 7: Press on "OKay" and follow any further instructions. When prompt to restart the computer, just do so and when your computer starts back up, voila, you should now have working wireless internet again.

Cheerio!
