Hello guys, need a help or suggestion here.

currently id moved into my new house and installed my unifi at the hall area. Let say I place them at right side (coz the point already built-in there) of the hall and of course I plan to put my TV there also. But the problem came when we bought a sofa that so huge making it not suitable to place the sofa opposite of the unifi and TV. So we decided to place the sofa at the unifi place, meaning now instead of previously my unifi at right side now i need to move them to the left side. the problem is the cable is not long enough and it will make my wall not nice with the long unifi cable visible.

Any idea how can i settle this problem?

for fiber cable i think not much i can do right because it already installed when my house constructed. or maybe if they can do it will cost greatly.

so i think my option only to lengthen the cable from the point at my left wall to my right wall.

or i heard there is a device which can transmit the data through electricity? meaning i plug one end at my left wall and the exit at my right wall and then connect to the modem. so no visible cable at the wall. is such device exist lol
