maybe too late, now, too...

if they're using wifi off that router, it is probably active... it just makes a 
simple negotiation between the router and systems looking for the access 
information...

that's one way to work around the problem...

that would be a good thing, too... i'd have probably removed both of them and 
then gone ahead with a full router reset and dealt with the resulting setup 
problems on all the other devices... that way, i would know exactly what's up 
with the network and would not have to play the guessing game or cross my 
fingers and hope things work...

it is unlikely that it brought down the whole DSL service... it is more likely 
that it simply overwhelmed the router with requests... decent logging on the 
router or even protocol sniffing the ether would show if that was the case...

glad you got it working for them! good job!
