I want to run an Ethernet cable from my DSL gateway to my room. My desk is about 10 meters away from the DSL gateway, and I need a way to run the cable through my room's doorway.
But here's the catch: I live in Mexico, and like most Mexican houses mine is built with brick and mortar, specialized DIY solutions are rather hard to find (if you can't find it at Home Depot you're pretty much toast), and my doorframes are a tiny, little, contemporary and minimalistic strip of wood affixed to the doorframe's structure. Googling in English turns up results that assume I live in an American house made out of wood and drywall with standard doorframes; googling in Spanish turns up nothing.
I am also pretty bad at handling cables. So much, that this was literally the reason why I got fired from my first job.
Any ideas on how to pass a cable through a doorway?
