AP problems/ Problemas con un Punto de Acceso

Configuration:

ap(config)#bridge irb
ap(config)#int bvi1
ap(config-if)#ip address 192.168.0.1 255.255.255.0
ap(config-if)#no sh
ap(config)#int dot11radio 0
ap(config-if)#no shut
ap(config-if)#ssid SSIDNAME
ap(config-if-ssid)#authentication open
ap(config-if-ssid)#guest-mode
ap(config-if)#encryption key 1 size 40 1234567890
ap(config-if)#encryption mode wep mandatory

errors:

*Mar  1 00:05:18.567: %DOT11-6-ASSOC: Interface Dot11Radio0, Station ap 0018.de8a.15a0 Associated KEY_MGMT[NONE]
*Mar  1 00:05:19.025: %DOT11-4-ENCRYPT_MISMATCH: Possible encryption key mismatch between interface Dot11Radio0 and station 0018.de8a.15a0

some implemented no working solutions:

-delete nvram: startup-config (like 10 times)

-erease start-up

-use WEP, WPA, WPA2, no security

-upgrade IOS from: c1240-k9w7-tar.124-3g.JA1 to c1240-k9w7-tar.124-21a.JA1 and vice versa

-use WEP, WPA, WPA2, no security

And nothing works!!!, my lap top just connects to the AP, but dont get dinamic IP adddress!, (DHCP server is working fine, ports too)

---------------------------------------

LAp-top----AP----modem(dhcp server)

Hola a todos,

Tengo un problema con un AP, lo configuro con los siguientes parametros:

ap(config)#bridge irb
ap(config)#int bvi1
ap(config-if)#ip address 192.168.0.1 255.255.255.0
ap(config-if)#no sh
ap(config)#int dot11radio 0
ap(config-if)#no shut
ap(config-if)#ssid NOMBREDELSSID
ap(config-if-ssid)#authentication open
ap(config-if-ssid)#guest-mode
ap(config-if)#encryption key 1 size 40 1234567890
ap(config-if)#encryption mode wep mandatory

al tratar de conectar mi lap top via inalambrica a la red, me aparecen los siguientes errores en consola:

*Mar  1 00:05:18.567: %DOT11-6-ASSOC: Interface Dot11Radio0, Station ap 0018.de8
a.15a0 Associated KEY_MGMT[NONE]
*Mar  1 00:05:19.025: %DOT11-4-ENCRYPT_MISMATCH: Possible encryption key mismatc
h between interface Dot11Radio0 and station 0018.de8a.15a0

y debido a esto no me da servicio DHCP.  si me marca conectividad con la inalambrica, pero no me da ip dinamica (el servicio DHCP si funciona) conectividad nula o limitada.

El access point ha sido reseteado como 10 veces usando el comando delete nvram: start-up como 10 veces y nada, incluso ya le cambie(upgrade) de IOS y sigue marcando los mismos errores.

Que mas puedo hacer???

Re: AP problems/ Problemas con un Punto de Acceso

Hola,

The messages "%DOT11-4-ENCRYPT_MISMATCH: Possible encryption key mismatch between interface Dot11Radio0 and station 0018.de8a.15a0" are pretty clear...

The encryption key is not matching between the AP and the Client PC.

Are you sure you are using the same encryption algorithm and key on the client PC?

Here is an example of WEP: http://www.cisco.com/en/US/partner/tech/tk722/tk809/technologies_tech_note09186a0080094581.shtml#acios.

Here is an example of WPA: http://www.cisco.com/en/US/partner/tech/tk722/tk809/technologies_configuration_example09186a008054339e.shtml.

Hope this Helps.
