I initially looked for the ability to whitelist MACs under Networks | select SSID | Advanced Settings. There should be option to restrict access to whitelisted MACs only and then enter the MAC addresses in 6 octet notation, either with or without colon separators. This way it can easily be pasted in with keyboard commands. The optimal GUI would show currently registered MACs with delete button next to each MAC and option to Add new MAC. It would also be great to display red/green indicator if each MAC is currently on the network. I do not think having option to select from a known clients list would apply to this scenario because unknown MACs should not be allowed in until whitelisted. Regarding product lines, this feature is valuable for all products that manage Wi-Fi networks. However, I am looking for it on GR10 specifically. Regards, Jim Mauck ECM Industries, LLC ... View more
