Why Is Wi-Fi Coverage So Bad in My House, and How Can I Fix It? If you and your router are on different floors - and it has removable antenna(s), you want as low a DBi antenna as you can get. DBi is antenna boost, and it's not magic - for a dipole (that's what you have, probably) DBi is increased horizontally by sacrificing vertical. Try an external wifi adapter on your laptop.
