DHCP Server seemed to stop working also. I have two WLAN with an AP30. An is bridged to the LAN and the other is a seprated Zone. In the separated zone i'm using the astaro DHCP.
OK, if you remove the DHCP server entry all together and just give the client who does have connection to AP, a static IP address there is still no connectivity. Client cannot ping gateway and 220 device cannot ping client. Client can ping itself and no fw running on client device.
