Problem
A Seattle attorney has Comcast TV service at his Seattle house. This attorney also works out of his second house on the Washington coast. The Xfinity streaming app used at the coast only allows him to stream certain channels, not all channels. Channels specifically excluded are the local TV station channels, such as KOMO, KING, KIRO.
Solution
Various pieces of hardware and software were installed and configured at both locations. The attorney can now stream and watch ALL Comcast channels at the coast as though he was at his Seattle residence.
