HI,

Our company is setting up a number of Ruckus ZF2925 APs. I’m new to this device. We keep seeing the same problem.

Wireless clients cannot acquire an IP address from the DHCP server. We can physically connect to a ZF2925 LAN port with a laptop and get an IP address from the backend DHCP server, but wireless clients cannot get an IP. Our configuration is as follows:

ZF2925 (WAN Port) -> Port 1 of VLAN Switch, Port 2 -> DHCP Server / Router

VLAN Switch Port 1 = VLAN 11 tagged, Port 2 = VLAN 11 Untagged

The ZF2925 is configured for a static IP. We are assuming that the “Gateway” entry on the “Internet” setup page must be set to the backend router’s IP. We can physically connect a laptop to a ZF2925 LAN port, get an IP from the DHCP server and setup the ZF2925. We cannot obtain an IP from the DHCP server from a wireless client.

This problem is consistent. If anyone could shed some light on this issue, it would be appreciated. Thank you for your help.

Tara, I’m assuming you have 4.1 installed on the 2925 (see Status—> Device). By default the 4 wired ports on the 2925 are member of the Management VLAN (51). Each of the 4 available Wireless SSIDs belongs to a different VLAN (resp 11, 21, 31 and 41). The WAN port is by default tagged and includes all VLANs. You mentioned any wired station will receive an IP address from your DHCP server, so I am assuming your VLAN switch forwards unknown tagged traffic (read: tagged VLAN 51 traffic) to a default or native VLAN and therefore it can reach the DHCP server on that native VLAN.

Are you using any encryption on the Wireless SSID? If so, just as a test, I would disable encryption temporarily and find out if the wireless clients now get an IP address. If so, then there is a mismatch between the encryption configured on the 2925 and the wireless clients.

Hi,

I tried removing security. Good idea, but same problem. Our 2925 is connected via WAN port to port 1 of our switch (tagged). Port 2 of the switch (VLAN 11 untagged) goes to our router / DHCP server. We know the path back to the router for port 2 – VLAN 11 is ok because port 5 of the switch is also VLAN 11 untagged and we can get a DHCP IP on a laptop connect to port 5.

I’m out of ideas. According to Ruckus docs, the configuration we have should work. But … no IPs are issued to wireless clients (with or without security). Signal strength is “excellent”, but no IP. I noticed other people on this forum had similar problems. Did anyone find a solution? Any suggestions on what we might try next? I would appreciate any suggestions.
