9.3 Step 3 - Connect Device to Available Acces Point

Scanning available access points visible to the device and typical output is shown below: (iw wlan0 scan). Selecting a specific access point and connecting using iw command and typical o/p is also shown below: (iw wlan0 connect <SSID>). The link can also be verified using the iw command: (iw wlan0 link). Finally, a ping test will ensure that the WiLink8 device is connected to the access point.
