WiFi Card of Laptop Does Not Detect any Available Wireless Networks

Hi Everyone;

        I am trying to help a friend with a WiFi Network Card issue.  Basically,  I have this laptop at my home which already has a preexisting wireless setup with an 802.11b wireless router.  I have the laptop in the same room which has the router and it still does not detect the wireless signal from the router.

          The WiFi card is a Ralink RT2500 Wireless LAN Card.  This laptop also has a VIA Compatable Fast Ethernet Adapter.  The IP Configuration for both show media disconnected for both.  I did a repair of wireless network connection, but, got a message saying Wireless Network Connection is not connected.  Wireless network unavailable.  

          With respect to technical specifications of the laptop, it is an Averatec Model #3200 Series.  The operating system is Windows XP Home Edition.  

           On a side note, I am wondering if it is possible that any software may be interfering with the functionality of the WiFi card.  For instance, I did notice at bootup a windows with the title of  Application Error with the following message.... Failed to load.  Some files are absent or corrupt.  Please reinstall application.  There is also a red triangle with a white exclamation point in the middle.   All of this appears right after the McAfee Security Center appears.  Of course, if there is not any connection between this message and the dysfunctional WiFi card, I can post this as a separate post.  In any case, I want to make sure to include all details which may be germane to the understainding of this problem.

          In closing, I look forward to any feedback or suggestions to this post.  Thanks in advance for any atttention given to this question.

         Thank you.

Hi

         Thanks so much for the great followup suggestions.  Just so I understand, what would be the necessary steps in disabling a program?

          Thank you

          George
That depends on the program. Most firewalls can be disabled by right-clicking their icon in the notification area/system tray and choosing 'Disable' - some will then open another dialog asking how long you want to disable them.

Hi Everyone;

          I am happy to report this situation is now resolved.  Apparently, the WiFi card was turned off.  When I pressed the button about the keyboard on the upper left, the laptop started to display available wireless networks.  

          In order to provide comprehensive closure to this post, I do have one followup question.  While the laptop is working fine with excellent signal strength and loading pages ok, will I still need to carry out a driver update?  Upon visual inspection of it within Device Manager, the version number is 2.1 instead of 3.2.  I figure it would not hurt to go ahead and carry out this anyway, but, I am unsure.

          Thank you

George,

Yes, I would reccomend upgrading your driver. I would keep the old driver available just incase the new driver introduces some bugs that affects you, but you shoul be just fine. Glad things worked for you!

Hi Everyone;

        Basically, this situation was resolved by pressing the WiFi button above the keyboard on the left side.  Interestingly, I noticed this button needs to be pressed each time the laptop is booted up.  It does not autodetect any available wireless networks as one would expect.  In any case, if the wireless button is pressed once, it activates the wireless which is is confirmed by the light for wireless turning on.          

        In closing, thanks so much for the great suggestions and insightful feedback provided to this post.  Great job!!!!   I learned much from this post.

       Thank you so much everyone.
