I suspect if DHCP broadcast packets are reaching DHCP server.
Please try below.
- Create a new SSID with default settings. Make sure correct VLAN is configured under advanced configuration.
VLAN 1 (default) = Untagged VLAN
VLAN other than 1 = Tagged VLAN (in this case, make sure same VLAN is tagged on switch's trunk port and all in between SW trunk ports).
- Connect the client and see if it gets IP. Run the troubleshooting utility on Unleashed.
- Try to connect a laptop on any second ethernet port of the AP and see if it gets IP (with default port settings, you should get IP on VLAN 1/Untagged).
If above is not working, you can take packet captures from the AP using wireshark and review (a bit advanced level if you are a normal user).
Also check and if you are using DHCP relay. Cross check if you are able to ping DHCP server IP address from the AP CLI.
If nothing works, feel free to open a support case for more help.
