Hello, I am experienccing the same type of problem, and I, have a 2wire router, too.
I tryed to add those you have adviced, and GSLAPT did worked well, but after I rebooted, this two lines in resolv.conf disapeared.
I added them once more, this time making sure that I saved editing by opening the file once more. They was there. But after reboot they disapered, too.
A tryed it for a few times, but get the same result.
Could you help me, please.
