Perhaps they didn't change the mac address on the Linksys to spoof their lan
card, but if they didn't, they wouldn't be able to access the service, as rr
locks to the mac address of the lan card. The only way this would be
possible is if they opted for a self-install and connected with the Linksys
from the beginning, then there would be no need to spoof the lan mac address.
If they used a time warner tech to install, the time warner tech wouldn't
connect the Linksys under most circumstances. This then locks the mac
address of the lan card to the service. If a linksys is later connected, it
would be mandatory to spoof the lan card mac address, thereby removing the
linksys mac address. I believe that this is how most roadrunner linksys
connections are made. They are still able to detect this somehow.
