I live in an apartment that provides WiFi that has MAC address whitelisting with a cost per MAC address slot.
What hardware/software can I use to connect to their network and rebroadcast in a new network so that all my devices can connect but the WiFi provider only sees one MAC address connecting?
I’ve tried a WiFi range extender but it appears to be forwarding the MAC address of the my devices
To be clear, the ISP broadcasts its own SSIDs throughout the apartment block and I don’t have access to any physical network sockets
You need a wifi router. Connect the wan to your network. One mac, wan doesn’t know about your devices.
This ^. That way you have complete control over SSID, connected devices, passwords etc, and you apartment block only sees a single MAC address (WAN).
Are there any routers that support this feature natively?
You could install Fresh Tomato firmware on any supported router and do this using wireless client mode: https://wiki.freshtomato.org/doku.php/advanced_scenarios
Connect using 2.4GHz, create own network with the 5GHz antenna?
And the WiFi router has to not be configured as a bridge device. It has to be it’s own DHCP provider.
Well, it has to be doing routing, at least. DHCP is a separate issue. OP could configure everything with static IP addresses, after all (although I don’t know why he would).
