Cisco 877 wireless router latest firmware. c870-advsecurityk9-mz.124-4.T1
When trying to set a mac address access on the wireless side, you can enter the mac address and apply it, but the mac address window then clears showing a blank.
When doing this with a IP address the IP address stays in the window. Is this a bug or does something else have to be set?
I would prefere to use the mac address for security. The mac address is from a wireless laptop if that helps
