Can I switch from PPPoA to PPPoE and back?
In most service areas you can freely switch between PPPoA and PPPoE. It is important to note that it may take the BellSouth gateway routers several minutes to properly detect the switch. Also note that in very rare instances, the routers may become “stuck” in PPPoE mode. In this case, it would be necessary to contact BellSouth Technical Support to switch back to PPPoA.
