Why won't my wireless clients get dhcp through my access point

I have a Buffalo Wireless N-Finity (WZR-AG300NH) set to AP mode.  This unit has a static IP and is using WPA for wireless security.  My router is a Sonicwall TZ-170 with the enhanced OS.  This is also my DHCP server.  We have no other servers of any kind on the network.  The employees are assigned an IP address just fine if they are wired in.  Wireless pcs, however, will not get an address until they are wired in.  Static IPs will work on the wireless clients but there is a great number of different units coming in and out which makes that impractical.  Once the wireless clients recieve an address through DHCP wired, the cable can be unplugged and wireless will function flawlessly.  

I have been completely stumped on this.  I have checked every setting on both units (that is, until you guys show me the one i missed) and cannot for the life of me figure this one out.

Thanks in advance

Ok, that model is a Router/AP.... First thing that comes to mind, is what port are you uplinking from the Sonicwall on? Are you using a switch port, or the WAN port?

that is a router/ap model.  It is hooked up through a LAN port. The switch on the back is set to AP mode

sorry, I should clarify.  the AP is run though a switch that is hooked up via the network to one of the Sonicwall's LAN ports ( port 1 or 2). The AP is attached through LAN port 1.  The reason I connected the AP to a switch is it allows me to pu the AP in a more central location.  The AP does not give pass DHCP even if it is hooked directly to the Sonicwall directly

I am not familiar with Buffalo products, and wanted to make sure you werent utilizing the WAN port.........

You can ping the Sonicwall wired THROUGH the AP, right?

Any security in the AP to prevent a DHCP broadcast from reaching the sonicwall?

I would look at Wireshark (or your sniffer of choice), and see if you can see whats happening to the DHCP requests via the packet capture.

i'll try the sniffer.  As far as security, when the switch is in AP mode, there is no security outside of wireless security (WEP, WPA, etc)

sniffer showed activity for dhcp from the AP.  I am unsure how to get the sniffer to see if the requests are being passed between the AP and the SonicWall

Put a hub inbetween the 2 devices, and you should be able to see it..... Or not see it....

I've determined that it's just a compatability issue with the two devices.  They will both work with other devices, just not with eachother.  I assume this could be fixed with a firmware flash, but with this lawsuit Buffalo has going I could be old a gray before one is available.

I figured it out myself. The SSID had a space in the name which the clients did not like so an IP address could not be assigned. Thanks for trying anyway. I would like to close this thread.
