WiFi Guard shows one MAC address for devices behind a wireless repeater
Sometimes you may notice that WiFi Guard reports one MAC address for all devices behind a wireless range extender or repeater. In this case it would look like that the devices have different IP addresses, yet the same MAC address.
A range extender typically hides devices behind itself and does not retain their MAC addresses. You can type arp -a in a command prompt and observe the same behaviour. This is not a bug in WiFi Guard.
One way around this issue would be to enable the WDS mode (Wireless Distribution System). The advantage of WDS is that it preserves the MAC addresses of client frames across links between access points. The drawback of WDS is that devices from different vendors may not be compatible with each other.
