Anything worth doing is worth over-doing. Archive: https://archive.today/ueKDL From the post: >>The first item on the list was actually the biggest constraint for me, and it led me down the rabbit hole of discovering VLANs in the first place: I had no idea what they were and that I needed them before I started researching. Don’t worry, if you don’t know what they are either I will do my best to explain it very carefully below. My first thought was: the fibre enters my house in my living room, so how can I have my router in the office? I figured it meant the connection would need to first go into the office, through the router, then back out to the living room across a second cable. I spent a bit of time looking into how to lay additional cables, and then realised it was going to be extremely expensive and annoying, so started trying to understand whether it was possible to use a single cable to accomplish what I wanted.
