Switched to WPA2, DHCP client stops working

So I recently setup a wireless client and have had it working both unencryped and encrypted with WEP.

I’ve since tried to switch to WPA2, and when I do so, the DHCP client on the RouterBoard stays in “searching” mode.

On the AP, DDWRT shows that it has issued a lease to the router.

Has anybody had this issue?

My access point is a WRT54GL running DDWRT using WPA2 Personal encryption.

My router is a RB411AH with an ubiquiti xr2 running 5.0rc1 set to connect to the AP through wlan1 using WPA2 PSK/tkip. I have a DHCP client sitting on wlan1.

This same setup works if my AP/Router is set to either WEP or no encryption.

Any ideas?
