I need to speak to a live agent about adding an ethernet line in my home office.

I work on streaming in my home office and find that the router in the living room along with the "wifi pods" are not strong enough to have a stable connection for conducting live streaming for video podcasts. Or should I add another router that I can plug into in my office. The router is inside another part of the house and would be inconvienent just to run a hard wire all the way from the router in the living room. It is NOT practical to do this as it would have to run through the living room, dining room, kitchen, garage and then into home office. What are my options?
