I am a new member of BBO. I am able to invite anyone to my table. But when someone invites me, sometimes they get the reply that I am not logged in, and I am. Then if I unplug lay Modem for a few minutes and turn my MacBook air off and then power it on, everything works fine. What is wrong, My Modem /router? I am scheduled for a team duplicate game on Friday, and wonder if I need to upgrade something? Toni8384
