The password can be either extracted or generated for all the routers sky have supplied to date. They are supposed to be releasing yet another new Sagem router soon though.
If you have a D-Link or Sagemcom that has upgraded itself to MER login (version 2 firmware) then you need to downgrade it to extract a PPPoA userid/password. If Sky start supplying routers with MER and no downgrade, then things will get interesting.
There's new firmware for the black Netgear one with mer support too, but they haven't rolled it out yet.
The upgraded firmware supports both PPPoA and MER connections. The older sagem router apparently reverts to PPPoA for a while if you reset it, so I'd guess it may initially connect using PPPoA and download a config which makes it switch to using MER, if on one of the new msans. I think others probably attempt to connect using Sky's MER settings on vc 40 and fall back to PPPoA on VC 38 if they fail.
If you can figure out a way to gain root access to a router, it is then relatively easy to extract the password if you have an active PPPoA connection, but if it is connecting using MER, then you might have to crack the code that generates the password, so it would be more difficult
Sky will presumably continue supplying routers that support PPPoA as long as they are offering Sky connect. But they could decide to disable PPPoA internet access on their new network once they've updated both Netgear routers.
