Use an ethernet cable from your computer to the router.

Get a long enough ethernet cable between router and PC. Far easier then installing optical cable.

Wi-Fi?

You might find plugging in a repeater or powerline network adapter in your room and running some short ethernet from it to the PC to be neater.

Fiber doesn’t run inside walls, only copper cable in inside walls. Fiber requires straight runs, for the most part, & most fiber doesn’t run to the prem, but to a poll somewhere nearby.

You would need to hardwire an ethernet cable preferabbly cat 6 to your modem. You could do it the ghetto way or the hard way but actually making a faceplate on your wall and running the cable up through your attic or down through your basement (whichever is easier) You are going to need tools to make this happen (rj45 crimper, wire strippers/scissors,faceplate with a rj45 slot.) You cant beat the speed you will get from a hard wire straight from your modem. Nothing good comes easy.. You could also just blow a hole out of your wall next to your modem and then wrap the cable around your house until its outside the space where your pooter is and blow another hole right through. (dont forget to silicone the holes)

Ive a cat6 cable running around 250ft and have no noticeable speed or latency issues.

stop giving advice on things you dont understand.....i have fiber going right to my back door as my hub is mounted to the wall next it.....fiber can be bent and is run in walls.....

About 30 years ago, at one of the companies, I had 100 Mbps fiber optic cable installed in a room along the walls. I don't remember the bending radius of the fiber, but it wasn't very large.

Ask AT&T to move it for you.

Then perhaps the answer is not as simple as you had hoped for, or perhaps the answer is "no". It is also possible that you did not clarify your question enough so there is a lot of misunderstanding.
