Problems with WEP/WPA with Aironet WLAN-Card

uwe.schreiber · ‎07-17-2007

Hi,

i'm using a Cisco Aironet PCMCIA-Card in my Notebook (CB21AG)

Several pages are not reachable, if the encryption at my router (TP-LINK 802.11g) is enabled. It doesn't matter if WEP or WPA. If the encryption is disabled, all pages are reachable. This affects also www.cisco.com

The problem is definitively the Cisco card. All other Computers in my LAN are connected fine without problems. The chipsets are Ralink and Intel.

I'm using the latest drivers and also the latest Firmware at my router.

Any ideas ?

Thanks Uwe

Encryption when enabled should be done both on the AP and the client card. Ensure that encryption keys match on the AP and the client. Only then the client can communicate through the WLAN network.

Hi,

of course i know how to set up the encryption in a wireless network.

You have read all of my posting ? I have written, that the problem occurs only with a few websites (e.g. www.cisco.com)

Most of the websites are working fine.
