What other advice do I have?
Wireshark is the world's most powerful network protocol analyzer tool. It can be used for various purposes such as, analysis of protocols like TCP, HTTP, UDP, and complete analysis of networks and troubleshooting. It has the option to use the wireless adapter directly in promiscuous mode for interception of wireless packets. It is much more effective than other tools such as tcpdump and dumpcap with a good user interface and hex detection.
