@SBDeco as per the mentioned post for X20 V4, firmware 1.2.x version supports whitelisting. However the latest version of firmware on my router is 1.1.8 ... how can I get versio 1.2.x ... does V4...

I saw a thread that mentioned that MAC Whitelisting has been added to X50 and other models would follow. Can you please let us know when this is planned to be added to X20 ?
