Extending Your WiFi via cable have the advantage, compared to extending via WFi, that You keep the bandwidth at max. Extending Your WiFi with products that use the same frequencies, as Your WiFi, will just put through 50% of the data flow. One way to extend the WiFi is with a cheap router, or maybe an  old router You  don't use any more.

Updated 2019-02-05 ! Using  Homebridge for a while , getting nice hardware to emulate Apples HomeKit devices, I finally decided to test IKEA:s Trådfri concept. The actual device that I was interested in is the wireless control outlet. But they have bulbs and other stuff that is really nice priced. This post will cover an installation of the Trådfri gateway with a HomeKit approach.   Other  HomeKit posts  on this Blogg

Upgrading from Jessie to Stretch can break the entire system so ALLWAYS do a backup. There are several sites/posts with "how to" information but the Raspberry site , the Linuxconfig site and the Superuser site ,  (where You can find more details about the upgrade),  made the base for this post.

TP-Link Deco  is a smart Mesh system that extends Your WiFi. It is pretty easy to install but there is no direct information in the install app, Apple or Android , about how to interconnect the Decos with ethernet.  Especially if You  must  keep the old Router. Connecting via ethernet is faster and more stable and also necessary if the Decos WiFi can't reach each other. Another post with DECO:s in router mode .

In a former post a I presented our approach to mix a modern NMEA 2000(N2) network with the older Raymarine ST 1 network, installed 2006. During the Years it has grown and been added with new functions. The pictures to the right is the actual layout. The first add on was a N2 GPS described here .
