Model Firmware Version Fixed In
WAP321 1.0.4.4 1.0.6.7

Problem Description

Intermittently the wireless client doesn't get an IP from the DHCP server.

The WAP321 stops forwarding DHCP traffic after some time on one SSID when the DHCP responses from the Server are broadcast instead of unicast.

The WAP321 is running for some time and the DHCP server responds to DHCP requests as broadcast messages.

A temporary solution can be found if you reboot the device. If the issue happens to all SSIDs, then you can configure the DHCP server to use a Unicast Message.
