Hello,  
I’ve been trying to get my RCM5600W to connect to a WPA2-PSK (CCMP) network for a few days now with no luck. I can connect fine to an open AP, WEP, or WPA-TKIP network, just not WPA2.

I’ve tried both compile-time and runtime config, but the results seem to be the same. Here’s how I was doing the runtime configuration:

```auto

ret = ifconfig(IF_WIFI0,
   		IFS_DOWN,
		IFS_DHCP, 1,
		IFS_WIFI_SSID, strlen("wetlabs-n"), "wetlabs-n",
		IFS_WIFI_REGION, IFPARAM_WIFI_REGION_AMERICAS,
               IFS_WIFI_MODE, IFPARAM_WIFI_INFRASTRUCTURE,
		IFS_WIFI_ENCRYPTION, IFPARAM_WIFI_ENCR_CCMP,
		IFS_WIFI_WPA_PSK_PASSPHRASE, "",
               IFS_WIFI_WPA_PROTOCOL, IFPARAM_WIFI_WPA_PROTOCOL_ALL,
               IFS_UP,
               IFS_END);

```

ifconfig() returns a 0 (success), but sock\_init\_or\_exit() just sits and spins forever while attempting to connect. However, just by changing the IFS\_WIFI\_ENCRYPTION settings to IFPARAM\_WIFI\_ENCR\_TKIP and the SSID to a WPA/TKIP router, I can connect fine (using the same passphrase).

Any ideas what I’m doing wrong here?  
Thanks!
