Wireshark · Wireshark-users: [Wireshark-users] radiotap RSSI v.s. IEEE802.11 RSSI

["iodavide@xxxxxxxxx" <iodavide@xxxxxxxxx>]

Hi,
I'm using Atheros device and I'm capturing data from monitor interface 
using Radiotap
To better understand link quality I've selected two columns: 
IEEE 802.11 RSSI and a custom colums radiotap.dbm.antsignal
I'm very surprise 
to see different values for those columns and would like to know why IEEE 
802.11 RSSI show strange positive values instead more reliable values showed 
by  radiotap.dbm.antsignal
I'm think radiotap.dbm.antsignal and radiotap.dbm.
antnoise are reliable, isn't it?
