If you have baseboards or carpet, this job becomes much easier. You can get thin or flat cables that you can just push between the carpet and baseboard. If you have hard floors, you can get a trim crowbar and pull the baseboards off. As long as you are careful, when you replace them and add a bit of caulk, it will look like new. Going around door frames is usually not so difficult: the worst case is that you would need to remove the baseboard from both sides and drill through the floor plate, which will also be invisible after you've finished. If you have a run that would have to go under carpet, you can use an undercarpet fish tape and some very thick sewing needles to raise the carpet and underpad at any place it is stuck. If you would have to go through a wall, often there is a cable box in the same section of the wall on both sides. That would let you string a cable between the boxes. In some cases you can add a box without it being obvious. Most corporate landlords aren't going to remember if the 11th layout in their building has an ethernet box in that location. https://www.amazon.com/LABOR-SAVING-DEVICES-85-125-Undercarpet/dp/B00009WE0I https://www.amazon.com/LABOR-SAVING-DEVICES-85-125-Undercarp... https://www.monoprice.com/product?p_id=44496 https://www.monoprice.com/product?p_id=44496
