I’ve posted on this problem before but I thought it was solved. But I am experiencing this problem again. I have a 2011 MacBook Pro (Broadcom network adaptor). When I plug the ethernet connection in, sometimes the connection works, and other times it doesn’t. When it does work and I unplug it to go somewhere, it doesn’t re-connect, especially if I connect to another network. Can anyone help me diagnose what’s going on?
Thanks,
