In this lab, we investigate the 802.11 wireless network protocol.\tA trace of captured 802.11 frames is provided to analyze. This trace was collected using AirPcap and Wireshark running on a computer in the home network of one of the authors, consisting of a Linksys 802.11g combined access point\/router, with two wired PCs and one wireless host PC attached to the access point\/router. In this trace file, frames captured on Channel 6 can be seen. The wireless host activities taken in the trace file are:\t\t\tThe host is already associated with the 30 Munroe St AP when the trace begins.\t\t\tAt t = 24.82, the host makes an HTTP request to http:\/\/gaia.cs.umass.edu\/wireshark-labs\/alice.txt. The IP address of gaia.cs.umass.edu is 128.119.245.12.\t\t\tAt t = 32.82, the host makes an HTTP request to http:\/\/www.cs.umass.edu, whose IP address is 128.119.240.19.\t\t\tAt t = 49.58, the host disconnects from the 30 Munroe St AP and attempts to connect to the linksys_ses_24086 AP. This is not an open access point, and so the host is eventually unable to connect to this AP.\t\t\tAt t = 63.0, the host gives up trying to associate with the linksys_ses_24086 AP, and associates again with the 30 Munroe St access point.<\/p>\n","protected":false},"excerpt":{"rendered":"
