This is more of a home renovation problem than a technology problem.

You can plug as many devices into a router or Xfinity gateway as it has ports, and if you run out you can just buy an ethernet switch.  They're cheap if 1Gbit is good enough, and unless you have Comcast Fiber you won't need more than 2.5Gb for full Internet speed, so still less than $100.

The tricky part is pulling the cable.  Making this look nice involves running cables inside of walls so you have a nice wall jack to plug your PC into.  In most houses you can easily drill up into a wall on the first floor from the basement at least if it's unfinished or you have a drop ceiling and can just temporarily take down some tiles, but getting to the second floor is usually more difficult and may involve opening walls and drywall/plaster work to put them back together.  Of course you can also do things gamer college student rental style and just get some of those 3M Command hooks and run the cable along walls, ceilings and floors and under doors.

Is there is a coax outlet up there ? If so, and if your employer will allow it, another option would be to use a MoCA solution. It's ethernet / hardwire over coax cable. You can Google MoCA for more info.
