This may be a long shot, but I understand that dual band modem/routers automatically connect to wifi devices using the 5 ghz frequency, not the 2.4 ghz frequency. But, the 2.4 ghz frequency has a longer range. So, if you can get the wifi devices on the third floor to connect using 2.4 ghz, they may work better. Good luck.
