i have very bad wifi reception in my room (there are two walls and a fireplace in between). the current router model is a Fritzbox 7430.
there are several options:
A: try to boost tx power in the router.
B: buy a wifi repeater or build one myself.
C: there's a coax cable coming out of a wall in my room...
C1: figure out if internet comes out of it and use a second router? idk if it even works like that, sounds useless.
C2: replace the coax with an RJ45, plug it into the router and put an AP in my room.
no open APs in the vicinity, and no i won't hack neighbors.
mobile hotspot also not an option because i have absolutely no mobile reception here.
what's my best option?
