Hello Ernest, I'm going to think that you have a Vizio Smart TV; (only happens when using SmartCast?) In this case it is a variant to perform a Factory Reset, it is very likely that it will be restored to normality.
Anyway, you should check the Moden or Router (if you have it) connection does not seem to be the application, but as if it were connectivity problems because in Vizio SmartCast mode is included in the included applications.
I leave a link to follow the procedure to factory reset.

Start with the simplest answer first so make sure the laptop's WiFi is turned on. If you have set the router to provide a closed network your laptop will not see it automatically and you will need to enter the WiFi network settings in network setup. if you are using Windows click start, click control panel and click network, on the left hand sidebar you will see "Setup a Small or Home Office Network", follow the wizard and you should be able to get connected. If you are using Mac OS X click the Airport icon on your menu bar, click "other network" and enter the SSID, select the encryption type and enter the network key (password). Lastly make sure that if you have chosen to use an access control list you have entered and allowed your laptop's MAC address in the list before trying to connect.

If you use your original Win XP disks, there's a chance you now have XP SP1 (Service Pack 1). Make sure you've made all the necessary Windows Updates as working with WiFi networks was enhanced with XP SP2. Then you can try to find your wireless network and connect to it. If you had a secured network you'll need your previous network key (similar to a password, but without a username, the wireless key is needed to exchange data with the router) If you can't remember the settings on your Linksys you can reset it to factory settings with inserting something into the reset hole to press the hidden buton and holding it for several seconds until lights on the front flash. Then you HAVE to run the initial install procedure (find your CD and Quick Start sheet) because your router will be open and unsecured.

Wireless adapter finds your AP... It clearly says that your wifi adapter is installed perfectly and working fine...
the issue is with your wireless router...
It is not processing the request given by your wifi adapter...
Either your router in dormant mode, in this state the router will keep on working with all networked computers, but it will not accept any new connections...
Or your router is highly secured that the computer is not capable of establishing a wireless connection with it...
Even if the Hardware(usb adapter) does not support the kind of security that is enabled in the router, you will have the same issue...
It is recommended to go with a WEP kind of security for the router as most of the devices are not compatible with WPA / WPA2 kind of password ...
Also if you have a feature called WPS(Wifi Protected Setup) enabled in your router, it would be better if you DISABLE this feature...
