Wireshark is a packet analysis tool which can be used for sniffing plain text for example text transmitted using http. Wireshark will not aid in sniffing your wep/wpa password or even your wps pin since this is not transmitted in plain text. However it is possible to do this using certain tools in kali linux (or linux distributions that supports pentesting tools)
Wi-Fi, or IEEE 802.11, is the standard for wireless LANs, or WLANs. The abbreviation Wi-Fi stands for Wireless Fidelity, and resembles the Hi-Fi acronym. It represents a whole collection of protocols within the same family of Ethernet and Token Ring. It is specified by various IEEE 802.11 specifications.
I will cover a detailed process of carrying out attacks since this forum is based on wireshark.

First you need to know what type of encryption is used by the neighbour's device. To do this you can use a tool known as airodump-ng or wash (if the device uses WPS technology) to sniff and determine the encryption method, and other details of the device.This can also be done with wireshark but it is easier to obtain what you need from the sniffing tools mentioned.
Once you know the encryption method, you can carry out an attack implemented (Try browsing youtube.com which has large volumes of pentesting videos)
COMMON ATTACKS
ATTACKING WPA ENCRYPTION WITHOUT WPS TECHNOLOGY
- wpa bruteforce attack- Tries to guess the WPA password using a handshake file and a dictionary that contains possible password guesses. Password guessing can be speed up with using GPUs.
ATTACKING WPS technology
- If the device uses WPS technology and WPS is not enabled, you can bruteforce the pin of the device using tools such as reaver and bully. Once the correct pin is found, the device will eventually spit out the password. A new flaw has been found whereby you can bruteforce the pin offline for some device that has 'weak' PRNG.
Note: carrying out an attack without your neighbours consent can put you in serious trouble.
