| Good afternoon,
|

my

it
| shows my wi-fi S/N ratio. Is NetStumbler good enough?
|
| TIA for your time,

||
|| The information is in IEEE 802.11-1999 specs found at:
|| <http://standards.ieee.org/getieee802/802.11.html>
|| Section 5.6 explains the difference between AdHoc and Infrastructure
|| modes. The problem is that the IEEE calls them IBSS (adhoc) and ESS
|| (infrastructure) modes. A client bridge is also known as an STA.
|| Reading IEEE specs turns my brain to mush. Therefore, I suggest you
|| digest the technobabble and acronyms in small bites.
||
|| Also see:
|| <http://grouper.ieee.org/groups/802/11/Tutorial/>
||
|| The info is in the probe response frame (which also supplies the SSID)
|| as in 7.2.3.9. Specifically, it's in the IBSS (adhoc) Parameter Set.
|| If it's an ESS (infrastructure) access point that's responding, the
|| field is blank.
||
|| It might be helpful if you try a wireless sniffer and looked at the
|| packets involved. See Wireshark at:
|| <http://www.wireshark.com>
