if this is a built in wireless cadr. verify that it is turned on, then go to control panel> network and internet. it should be listed as a wireless connection. if u are not seeing it there. then the drivers are not installed. get the drivers installed, u can also go to control panel>systems>device manager and look under the group for network adapters you should have at least 2 the realtek, which is the Lan card and one for the wireless. if only the realtek is listed the drivers for the wireless is missing and would be under a list that says Other devices with a yellow question sign.
enable the realtek and use the wired connection to get onlione to download the drivers for the wireless card. Youcan locate the drivers at the PC manufacturer web sites.
