There is a decrypt utility that comes with Airsnort that will do that.
I believe the latest version of kismet will also decrypt data when it's
given a WEP key. It can also pull in a dump file so it seems like that
should work too but I haven't do it that way.

Subject: Testing WEP Key on pcap dump
Does anyone know of a quick method or automated tool for accomplishing
the following:
I have a pcap dump using Kismet Wireless sniffer on a BSSID using
128-bit WEP encryption. If I think I know the 26 character HEX WEP
key, is there a way to easily decrypt all of the traffic for a
specific BSSID based on input of this WEP key, and then display the
decrypted pcap output in Ethereal? Or another way of seeing if this
WEP key is able to decrypt from the pcap dump for that specific BSSID?
