Why is the VAP11G-300 still unable to connect to the WiFi signal of the router after binding the MAC value of the tag on the back of the VAP11G-300 to the MAC-restricted router?

VAP11G-300 is a hexadecimal MAC value, it should be the back of the MAC value into a bit and then bind to the router, for example, a label is "0017131E38FC" device, the router at the upper level should be bound "0017131E38FD" because the VAP11G-300 contains multiple network cards, the MAC value into a bit is the MAC address of the LAN port can be bound.
