Basic wireless PCAP analysis

wireshark 
or
aircrack-ng <filename>

Sometime aircrack-ng can find the WEP password. If so the you can use the password in wireshark to decrypt the traffic

This can be done by selecting “Edit > Preferences > Protocols > IEEE 802.11” and
then checking “Enable decryption” and adding the decryption key.

To discover the wireless network name, aircrack has a wordlist function

aircrack-ng PCAP.cap -w /usr/share/wordlists/rockyou.txt
