WLAN with encryption and ARP-spoofing

Hello!

While preparing for a security-seminar I played a bit around with
ARP-spoofing on switches. After that we thougth a bit about encrypted
WLAN's and found out that we can also sniff all packets when we use
ARP-spoofing, so the encryption (even with keychanging applied) isn't
really useful since it is no problem to grep all packets decrypted.

Do you have any idea's how this can be prevented?

best regards,
Markus
