Hi everyone!

I am trying to extend my internet connection to my Grandpa’s house using Wifi routers and range extenders. We are not currently using Wifi6 equipment so I don’t think we need Wifi6 Routers/Range extenders.

Please let me start with explaining my current configuration and problem. As you can see in image attached above, I have internet in my house and it is connected to ONU with Router. I've connected two Wifi Routers in bridge mode to extend Wifi to my house’s living room and to my Grandpa’s house. Each color(Blue, green) represents SSIDs. I also bought Wifi Repeater to extend Wifi in Grandpa’s house. But equipment are very old(like one decade) and Wifi are too weak. Will not fully reach my living room and will not fully reach all rooms in my Groundpa’s house.

Now, let me explain my ideal configuration. I am going to buy three C6 Wifi Routers and three RE330 Range extenders because they are like $25 each. Going to attach two Wifi routers in bridge mode to ONU just like my current configuration. Difference is that I am going to add RE330 Range extender to extend Wifi to my living room. I am also planning to add another RE330 in my Grandpa’s house, connect C6 Wifi Router in bridge mode to RE330 by LAN cable, and add another RE330 to extend Wifi to whole Grandpa’s house.

Is there any better option? Do you think my ideal configuration is possible?
