[BAWUG] Re: "indefensible" WiFi flaw

[Daniel Dobkin]

I took a look at the AusCert posting for this problem.  It appears to 
be nothing more than setting a card to send packets continuously, thus 
setting everyone's carrier sense high and blocking the channel.   The 
press release maintains that the transmitter 'cannot be located' but 
this is a mystery to me:  since the transmitter must send continuously 
to cause a problem, it ought to be quite simple to locate the offending 
node using raw signal strength or (preferably) a directional antenna 
and a spectrum analyzer.  For large organizations that are likely to 
own the space around their network, the offending node would be on 
their property and could be shut down or asked to leave.  In any case 
it certainly isn't news:  FCC part 15, "unlicensed devices must accept 
interference".
