You didn't say where the router is currently positioned. Halfway along the length of the bungalow would be the obvious position but then -both- devices will likely be reporting a 3/4 or 2/4 strength signal.
I will take it as read that you've
(i) tried changing the location of the router already and
(ii) that you're following internet provider's recommendation to keep it as close to the 'master' phone socket in the house.
A domestic router should be good for a range of up to 30 feet. With a bungalow, you might have problems with plasterboard cavity internal walls which have a metal foil heat-reflecting coating. This will partially block radio signals. Clear line of sight from the router to the laptop and the TV will get around that possibility.
