But instead of buying this! you can buy once router and connect the both the routers remotely and locate the new router near by you and start connecting to the new one!

Sometimes just getting a new adapter with a directional antenna that you can point  toward the signal source will be enough. Or if you control to the AP adjusting the antenna on it might do it.
