One option I have used is to insert a flat LAN cable between the carpet & skirting. They are readily available in CAT5e, 6 & 7 in a variety of pre-constructed lengths. 5 & 7.5m lengths have worked well for me. They go around sharp bends more easily than regular cable. Years ago when we replaced the carpet, we put antenna cable in the gap between the floor & skirting to a more convenient point.
I have a difficult home to cable. During a past partial reno I had a few LAN points done that were cable accessible. During a subsequent change, they damaged the longest cable run. The LAN points never seem the right place, so I now have 3 skirting installations. The desktops, printer & TV/media unit are all hardwired. The difference to wireless is noticable, but less so than when we first did this pre-AC wireless.
