I'm afraid your post doesnt make much sense to me. You appear to be talking about cable connections.

Vodafone uses DSL, PTM & CHAP authentication. As such a username and password (not Mac address) is required to be able to connect. The vodafone box was locked down tight and it was no simple task to get this information.
does hardwork not pay?
Yes it does. An awful lot of combined man-hours by members of this forum actually found a way of hacking into the Vodafone HHG2500.
Bishbashbosh was the first to achieve success in finding a way to extract the username and password, which then later had to be unencrypted by brute force.
As a direct result of the hard work from several of our forum members, Vodafone has now changed their stance on issuing login information to their EU's as long as they are using an MCT approved modem.
You can see the full thread
here - There were at least 5 Vodafone techs crawling all over that thread once news got out that we'd managed to hack into the Vodafone router and successfully obtain the required login info.
