If you really need better signal in that room, you could get a really long Ethernet cord and run it to that room to connect the access point to (but unless you want a cable running through your house, you'd have to drill some holes in the wall). You can get pretty long Ethernet cables for not too much on Amazon, but its not an instant solution.
Another option are power line adapters. These send the data from an Ethernet cable over your power lines. But they are pretty expensive and might not work too well if the two adapters are on different circuits.
