Does anyone know what that is? I am having no problems with my computer or modem, but I did a "connection check" for my modem and each and every category has "pass" listed next to it except "Continuity check to 6rd BR" which has "fail" and I have no idea what is is or if it is necessary at this time. I am thinking it might have something to do with the IPv6. Checking the IPv6 information from test-ipv6, it says that everything is 10/10 and my computer and modem are IPv6 ready. Thanks for any answers to my questions.
