My Router (Model: DI-624) is only allowing one wireless connection to one laptop. The other laptop is stuck hanging at connecting to the Internet

I have the SSID set as "Pedro-Home" and is using a WPA PSK secured password.

I have set the router using "Blaze-PC" while wired.

Both Laptops critically need the Internet.
