Why cannot I connect to my wireless network
Case1. the authenticating problem, password mismatch
1. Make sure your password typed is correct. You can refer to this FAQ to find the wireless password: How to find or change the wireless password on the TP-Link products
2. Sometimes it will ask you to type in a PIN number when you connect to the wireless network for the first time. This PIN number is different from the Wireless Password/Network Security Key. Usually, you can only find it on the back panel of your wireless router/modem. If you cannot find the PIN or PIN incorrect, you may choose “Connecting using a security key instead”, and then type in the Network Security Key/Wireless Password.
If it continues on saying network security key mismatches, it is suggested to confirm the wireless password on your wireless router/modem. Please contact your router’s support for help if you don’t know how to confirm the wireless password.
NOTE: Wireless password/Network Security Key is case sensitive.
