WEP Key decrypt error

luc_despatie — Sun, 04 Jul 2021 19:33:48 GMT

We have WPA1 clients and web authentication with the WLC4402. I have this trap "WEP Key decrypt error" and after the client cannot log anymore on the wi-fi network. I have to remove the client from the controller so they can log on the wi-fi network

WEP Key decrypt error. Station MAC Address is 00:16:ce:20:59:66, Base Radio MAC is 00:14:c1:2c:00:00 and Slot ID is 0.

Why I have wep traps when I use WPA ? I don't use WEP.

Thanks

I get the same error.

WPA2 only with PEAP authentication.

I use the Intel2200BG Card.

I found in a document that the web auth will not work with encryption. I have confirm this with my system engineer at Cisco.

Cisco doesn't seem to have a plan to include the encryption and the web auth in a near future, but if everyone ask for it, maybe they will add it.

We are using 802.1x and 104 bit WEP to authenticate against a ACS Server

(LEAP)

Sporadically we are also getting the same errormessage muliple times:

Wed Nov 1 12:09:01 2006--WEP Key decrypt error. Station MAC Address is 00:40:96:b1:d1:01, Base Radio MAC is 00:0b:85:71:21:01 and Slot ID is 1.

Wed Nov 1 12:05:01 2006--WEP Key decrypt error. Station MAC Address is 00:40:96:b1:d1:01, Base Radio MAC is 00:0b:85:71:21:01 and Slot ID is 1.

It seesms that this error-essage are dieplayed in different configuration cenarios.

Does anyone know what exactly the reason is for this error message is.

(Execpt for the Cisco docu statement "Notification sent when the controller detects a WEP decrypting error.")

Hi ARmin

We actually have a TAC Case open now - since 2 months. Still working on the problem.

I'll let you know when we solve it.

I am seeing the exact same issue using Symbol 9060 RF guns. The fat AP's dont have an issue at all but when i try and use the LAP and WLC 4400 it gives the WEP error. The clients randomly drop and have to be reset with a warm boot to get them back up. Please let me know what you find. I also have a Symbol engineer coming out tomorrow and I will ask them what they think as well.

I think WEP errors that you are seeing on the Controller has anything to do with the clients dropping connection. May be the clients have some problem staying up or there are holes in the wireless coverage. Signal interference can also make the clients to drop connectivity.
