Hi, Fraser (coffeebaron) is the man to sort this for you, assuming what we understand is correct, ie ETP > Kitchen > Office > Lounge, then I would recommend you have all the legs (except the ETP) converted to ethernet, move the router to the workspace, use the kitchen to workspace link to ship the wan to the router, and then use the workspace to lounge link to ship the lan from the router to the smartTV.
If you are lucky you might be able to get the kitchen connection from the ONT to the workspace link all within the wall meaning no random cables on view.
