I am seeking a professional network engineer to analyze a PCAP log I have here to try and explain we have a loss-of-connection situation for a network device.

Expert knowledge of TCP, IP, ARP, TLS, and 802.11 PHY will be required.

I have a device that runs an embedded WLAN stack, connecting to a commercial wifi network.

An unexplained, reproducible case is encountered wherein the device experiences a loss of ability to operate on the IP network, but not a loss of association with the WiFi AP.

This device operates well on consumer & domestic WiFi, but more commonly fails on office & commercial networks. The device itself only supports 2.4Ghz wifi operation, so 2.4/5Ghz handoff and other issues in the 802.11 PHY are suspect.

A wireshark capture of network traffic from a notebook associated with the same AP has been taken and will be provided as the subject matter.

Deliverables will be:

- A list of useful filters to apply to this PCAP and future captures for debugging this case

- A brief writeup of the observed transactions that the devices does make

- Suggested follow-up actions for additional captures that would/could be useful

- Proposal of theories for a root cause, if no "smoking gun" is found.

- A bonus is to be paid if a root cause is found and fully explained with a post-mortem/technical brief

Ongoing contracts for internet protocol/IoT analysis will be available.
