Hi alzhao:
The WIFI connection issue between GL-AR750 and my home router is resolved.
Previously, I have turned OFF the Wireless radio which I believe was the reason for the issue. When I turned ON the wireless radio, the connection is going through continuously.

Now, the reason I turned OFF the wireless radio was because, I connected my computer to GL-AR750 using a cable and not through WIFI. Also, I wanted to prevent any other wireless devices connecting to GL-AR750 using WIFI. This was done so to make my private network really secure.

Now, as I have to keep the wireless radio ON, to enable a WISP connection to an external WIFI network, can I restrict the wireless devices that can connect to GL-AR750 based on their MAC address?

If this is possible, can you help me where I can enter the MAC addresses in GL-AR750 for the devices which are allowed to connect to GL-AR750’s WIFI network?

Thanks for your continued support.
