[Nottingham] OK, where has 9/10 of my network gone?

For Android, yep, I make good use of an old version of WiFi Analyzer.

There must be similar utilities directly for Linux...? ;-)

For some background on the confusion of channel allocations for 2.4GHz
WiFi, see:


For my locality, there's at least 6 neighbouring WiFi SSIDs and we are
all nicely cooperating on using only channels 1, 6, and 11. Until that
is some occasional ninny switches on and splatters us all with noise
from channel 10...


WiFi is low power radio and other electronic equipment can wipe you out
with noise for a 1 metre exclusion zone...

See what you can see...

Good luck,
