You can use the quick fix (presently at this moment) to enable the DHCP
server on EAP300v2

1. In the configuration page, just add
/html/LANSettings at the end of the browser link and you
get the "Use Router as DHCP Server" menu.
For example :
2. Tick on "Use Router as DHCP Server",
make your configurations and press Accept.
3. Type (or
what ever you assigned the IP) and press Save/Reload. You should
see dhcp.lan.ignore=0. This is correct. Press Save
and Apply to take effect.
