Hi there.

For some very unknow reason Wireshark is using nonstandard IEEE names on fields nd Information elements calling them TAGs. The correct name is IE information elements and IF information fields. Most other tools uses the correvt term. I do not know why Wireshark developer are using invented terms.

And a much more serious issue. Later versions of Wireshark also add information coming from the Physical Header of the 802.11 protocol. se example below. A there are other tisng strange in teh WIFI decoder.

A-MPDU aggregate ID: 583
[Duration: 40ms]                              Confusing term used here.  And how is this calculated? Duration means something else in the IEEE 802.11 STD.

[Preamble: 20ms]
[IFS: 2489ms]                                  IFS means something totally different in the 802.11 STD Stupid name
[Start: 49515891ms]                        What are those numbers coming from.
[End: 49515931ms]

I suggest that Wireshark developers consult with IEEE 802.11 experts.

That, as well as the "Start" and "End" field (and possibly also the "Duration" field in question), were added in this commit.

Given the name and email address of the person who made that change, he's probably this Simon Barber.

I suggest that Wireshark developers consult with IEEE 802.11 experts.

According to his LinkedIn page, he was a co-technical editor of the IEEE 802.11 standard for 4 years and 2 months.

I wouldn't give @maer any credit whatsoever, considering this person can't even post a simple question - or perhaps unfounded rant as a better term - without numerous spelling errors. If someone is to be taken seriously, he/she/they should at least be able to intelligently and coherently convey their concerns. This is a "question" begging to be deleted.
