umm.. given that wifi is "free" unregulated in most/all cases..
Disclaimer? I work on IEEE 802 wireless standards. I know them all too
well. I am the chair of the 802.15.9 taskgroup. Look me up at the
meeting Jan 11 in Atlanta...
Did you know that 802.11b was approved before 802.11a? Why was 802.11b
even done? Why was ODFM not in 802.11b and had to wait until 802.11g?
Yes, I get 802.11.
Oh and I was the author of the original papers on the myth of hiding
SSIDs and on how to crack WPA-PSK keys.
why wouldn't you be stepping on his channels??
In the old west: first come land rights.
or stepping on someone else's channels..
As I wrote over a decade ago, the SSID is there to share the channel.
Much like NETBIOS SCOPE back in the days of large, bridged ethernets
(which we are seeing again in places like stadium wifi! Bounjour makes a
mess of those environments). A polite SSID tells who you are so that
those around you can know where to go to coordinate channel usage. With
11b/g you only effectively have 3 channels, and with planning you can
avoid conflicts. With a little overlap you can even work 4 channels.
11a/n and 11ac have more channels, but shorter range. Speed or range;
you choose.
wifi permits numerous packets on same channels,, yes of course there
might be interference.. but you gets what you pay for!
Have you ever tried to set up wifi on a trade floor? A real mess. You
have to get everyone to turn their power settings down so that their
signal stays near their booths and not try to cover the whole show
floor. Of course BEACONS range much further than you can actually use
the network. This is why warflying works. And why you want power
values as well as channel.
And why NOT use the channels to get better performance? Be aware and
work with those around you and everyone gets better performance.
I just found a little tool, WiFi Radar, that is at least reporting the
channel, which is what I need right now. I would like one that also
shows signal strength.
I installed kismet, but it does not seem to be working....

Radio off!!! By me to save battery...
ARGH!!!
Been there, done that :-)
I am new to the Xfce interface, and in Gnome it shows you have Wifi, but it
is off. Xfce does not show anything about WiFi with the radio off. Thus my
panic.
I do like the simplified WiFi interface; when the radio is on. ;)
But I would like a simple diagnostic tool to show me which APs are on which
channels. New neighbor. I have to show him that he is stepping on my
channels and that he needs to change his.....
