Device has 5 bar conection on wifi on PC but won't connect to internet

I'm not exactly sure whether you are connected to the PC but can't see the internet or whether you are not connected to the PC. So I'll explain the difference and you can decide.

When you attempt to connect a device to a wifi network, the device will do a search for available networks. The networks in range will display, showing their SSDI (name), signal strength, and security status. This is not yet a connection, only a detection. To connect to the network, you need to select the one you wish to join and send a connection request. Unless the wifi network in question is a free hot-spot or is unsecured (neither a good idea to use), then the next thing that will come up is a passcode/security code popup. Here you must enter the passcode/security code that the wifi network is assigned in order to connect. Without it, you will not be able to connect or access the network or internet. There is also the issue of security type. Older routers and devices used a code system called WEP. Newer router use WPA/WPA2 encryption techniques. our device must support the security type the router is using or you will not be able to connect.
