Xbox One (Network Packet Loss 100% Black Ops III) A.B.C.D.E.F.-.H.I.J.K.-.-.-.-.-.-.-W.X.Y.Z. ...

FYI... I was able to play other games online. When I downloaded Black Ops III, I was not able to connect online. Received server error... "A.B.C.D.E.F.-.H.I.J.K.-.-.-.-.-.-.-W.X.Y.Z." error. searched on all forums, many potential solutions, all included
rebooting routers, uninstalling the game, resetting IP Addresses, power off/on Xbox one, testing multi-player connection in the Network Tab then clicking RT/LT RB/LB all at the same time to view network diagnostics, NAT Open or restricted and Cone NAT, etc.,
etc.... After a lot of work, I IP'd into my router and noticed that my router had UPnP enabled, and by disabling UPnP (Universal Plug and Play), I was now able to play Black Ops III online. not sure why it matters with Black Ops III when other games worked
and all other options I tried failed, but it did matter. Hope it helps anyone else going through the same issue!
