LinuxQuestions.org - deauthenticating from xx:xx:xx:xx:xx:xx by local choice (reason=3)

I'm trying to setup hostapd 2.0 for the first time on Slackware 14. I cannot find much on this error online. I'm using a TP-Link TL-WDN4800.

Code:

[13460.978537] wlan0: authenticate with xx:xx:xx:xx:xx:xx (try 1)

[13460.984363] wlan0: authenticated

All machines do this when trying to connect. I'm not sure if I have something wrong in hostapd.conf or if I need to set up some kind of firewall rule for wlan0. I have dhcpd listening on wlan0 or at least it says it is and it works fine for eth1 (internal network).

Any insight will be much appreciated. Thanks.
