Check Ubiquiti and Deliberant products. They are high powered radios that the wireless internet providers use. If you have a place outside to place the radio pointing towards the house with a decent sized panel / sector antenna then that may cover your whole house from one radio.
I have also setup different radios one place or another for better coverage. I have gotten a good ways down the street using the wifi on my phone to still receive text/phone calls using Talkatone since cell reception is poor. I setup each with different SSID's and on separate channels as far away from each other as possible (channel 1 and channel 11 for example) as most others use channel 6.
2.4 GHZ penetrates objects better than 5 ghz but bandwidth is greater as the frequency increases.
