Can we boost Wi-fi signals at home? If so, how?

If you mean you have Wi-Fi from your Internet Service Provider (Like Comcast) and there are places it does not reach reliably, the best solution is Wi-Fi Mesh extending, but it's not cheap.

There are Wi Fi Signal boosters, devices akin to Modems.
I have seen some advertisements here and there but you need to either check with some local stores or check online.
