Extending Home WiHi

[Tfxw]

Continually struggling with getting a signal to far corner of stone house.  Added 3 Pods but that didn't do much.  This site, https://www.xfinity.com/hub/internet/extend-range-of-wifi-network
, mentions Long Range Antenna and Signal Booster.  Is there a preferred product to work with my Router and is it something I can get at xfinity retail outlets?

Thanks, I can do Google searches as well. What I was hoping for was a response from someone who already knows that Xfinity prefers specific devices for either an Antenna or a Booster, or someone with specific recommendations for proven devices that work with Xfinity routers.

Any device will be compatible.

OK then, that helps. Thanks.
