I have been looking for a wifi system that will work at my mom's house for years. She lives in the Dominican Republic and houses there are made of blocks and concrete. So as you can imagine, wifi range isn't exactly reliable. Anywhere beyond 40 feet makes the signal unstable and prone to dropping because it has to go through multiple solid walls. Currently, I found a "hack" where I connect a router to her cable box's ethernet port, but this lead to having five different networks across the house. SSIDs which end up having interference between each other and having to be on the lookout for which router provides the best signal and speed.
I have tried extenders, but I have ended up buying around 4 of them over the past two years because of either failure rate or crap performance while also having the same problem as with the current setup, having to be conscious of what network you're on. I have even tried using the same network name for the routers, but that ends up giving IP address issues in the long run. Would a system like this be a viable option for a house like this?
