I configured a TP-LINK TL-WN721N to serve as an access point using hostapd. I'm using WPA2, and I've set up MAC filtering, and a 16 character alphanumeric password from GRC. What else can I do to make my network more secure? This is my first experience with WiFi.
Thanks in advance,
I think that is pretty secure. If you want more, you could try something like forcing the use of a vpn; like, once they get an ip, they can only get access to the port of the vpn on your server, and everything else is blocked.
If they want something else, like web navigation, they have to do it over the vpn. That way, even if they get access to your lan, they can't do anything without the vpn certs. Try to do it using openvpn

Open source is about opening the source code complying with this conditions, period. The ability to choose among several packages is just a nice side effect.
