I would like wired Ethernet in my house, a couple weeks ago I asked about the risk of lightning when running it outside, I done some more research and found that my house has a cavity wall which means a gap filled with some insulation, my questions are:
1) Do I need internal or external Ethernet - I've read that PVC coatings on cables can 'melt' onto the insulation like 'soft chewing gum' so would external Ethernet be required, unless I could use some sort of conduit with internal Ethernet?
2) What device should I use for getting the cables up there - I was originally thinking some electrical fish tape going down attaching two cables and pulling 'em up from the living room to the loft but I've heard of magnets too would they work? I would ideally like a solution below the price of the fish tape I found at £15
Here are some pictures I took up there:
the white stuff appeared to be loose insulation, I had to move a 'bag' out the way to get to it, also note that I checked and there feels like a wall towards the camera and you can see a wall away from it
here's the area I'd be working with, space furthest away is the area where the insulation is, the wood slightly closer is on top of what I felt as a wall, the black wire is an aerial that the builders installed prior to us moving in, I wouldn't be able to fit a cable down there with it as it appears to sound like there's something under it and I don't want to have to redecorate (knocked on it), finally the thing on the other side of the cable is the ceiling
