Wireshark · Ethereal-users: Re: [Ethereal-users] Wireless sniffing - FreeBSD 4.5 + Cisco LMC352?

[Joe Tomasone <joe@xxxxxxxx>]

Is the AP using WEP?  WEP frames will show as LLC frames due to the fact 
that the AP manufacturers all violate the spec and do not tag WEP encrypted 
frames with the proper privacy bit.
