WLAN with encryption and ARP-spoofing

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?
