Cannot connect to the Access Point due to mismatch in SSID
The SSID is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. Multiple access points on a network or sub-network can use the same SSIDs. To establish a Wireless connection between the Wireless client and the Access Point the SSID configured on the Access point must match with the SSID configured on the Wireless clients.
If the Wireless client cannot connect to the AP, check if the SSID configured is the same on both the AP and client. SSIDs are case sensitive and should not contain any spaces.
