I used an older tp-link router (with green web interface). To limit wireless network access to known devices only I made use of Wireless MAC Filtering.
Everything worked fine unless I've bought a new Archer A9.
There is no MAC Filtering option in its "blue interface" so I've decided to use Access Control functionality with Wihtelist.
I've added some MACs to the whitelist and certainly enabled Acces Control function. And I really don't know if it works as should be:
- I am still able to connect via WiFi and gain access to LAN with device with MAC not whitelisted...
- After connect via WiFi the device obtain IP address from external DHCP (router's DHCP is disabled).
- I thought that not whitelisted devices cannot sucessively connect to WLAN or at least cannot access any network.
- But mabe this access control funtionality works only with DHCP enabled and WAN port connected? I don't use router WAN port nor DHCP. The router is only connected via LAN port with my local network with own DHCP and gateway to internet.
I'll be very thankful for any suggesions, help and explanation. I haven't expeced that new routers have less functions exposed to user via new "blue" interface...
