[kwlug disc.] detecting wireless

[Unsolicited]

Correct my impression: 300Mbps / 54 / whatever ... this is the total 
for ALL traffic occurring at the moment? i.e. If a 'router' is talking 
54, to 2 devices, that bandwidth is shared? They don't each get 54?

And something about a single 54 connection dropping all connections to 
the 300 router down to 54? Ouch.

For anything in area? e.g. Neighbours? i.e. Detectable presence of 
lower speed traffic in area, even if my neighbour's on different SID, 
drops my faster router down? Or, does it make sense to have a second 
wireless router upstairs on different SID for those connections you 
know will never talk (connect) at the faster speed?

  See other posts. Multiple intra-location communication - more is, 
well, more. And presumably any given conversation completing faster 
means less wait for another conversation happening around the same 
time. Stream that show from mythTV server in living room to basement, 
while daughter is streaming Britney to her iPod, and Ma and Grandma 
are having a husband-bashing conversation, VoIP.
