After doing some reading on the benefits of AES over TKIP I switched our WLAN security settings to AES, and pushed a new wireless policy to our client machines. Every thing appeared to work well, except now the trap log on the 4404 is showing a LOT of WPA decrypt errors. I've checked a few of the clients that appear to have problems, but they've got the right policy and WPA settings to match what is on the WLC.</P><P></P><P>It's not one particular NIC, it's various clients.</P><P></P><P>Any thoughts on how I might clear these up?</P><P></P><P>Rob</P> Sun, 04 Jul 2021 00:43:53 GMT https://community.cisco.com/t5/wireless/decrypt-errors-wlc-4404/m-p/1290857#M9294 rcoote5902_2 2021-07-04T00:43:53Z Re: Decrypt Errors - WLC 4404 https://community.cisco.com/t5/wireless/decrypt-errors-wlc-4404/m-p/1290858#M9295 <HTML><HEAD></HEAD><BODY><P>One reason for that is configuration of two WEP keys on a single WLAN is not supported.
