851W w/ WPA-PSK - Interface goes down

Hello,

I've been attempting to configure WPA-PSK on the 851W router. I've followed the directions using the SDM and successfully enabled the WPA-PSK wireless network. I connected a MacBookPro to the wireless network, with complete functionality, then after about a minute or two, the client disassociates and the Dot11Radio interface goes down.

I've setup an open network with no connectivity problems. I've search the net and Cisco forums with no success for a resolution to this problem. Here's the link to the guide: http://www.cisco.com/en/US/products/hw/routers/ps380/products_configuration_example09186a00808acf2f.shtml

Any ideas what might be causing the radio interface to go down with WPA-PSK configured?

Thanks.

For ceratin IOS version WPA-PSK is found to be intermittent. Cisco bug CSCeh90412 describes this. Try upgrading the IOS version and check.

Thanks for the response. After much testing with technical support yesterday, Cisco provided the most current IOS, which fixed the problem.

The problematic IOS version: c850-advsecurityk9-mz.124-4.T8.bin

The working IOS version: c850-advsecurityk9-mz.124-15.T1.bin
