I'm looking for a recommendation for a mesh Wi-Fi installation in a condominium.
The condo is U-shaped. Each "leg" of the U is about 43 feet (13.1 meters) and the "bottom" of the U is about 15 feet (4.6 meters). While the condo is only about 1700 square feet (158 square meters) there are some complicating factors. The router is located at one end of the U and it is not practical to change this. A television set with an Internet interface is located at the other end of the U, with a need for high-quality streaming. The condo is all one level but the walls are built with steel studs and heavy-duty 5/8-inch (1.59 cm) sheetrock.
I am thinking of a three-channel mesh network with the router at one end of the U where the ISP cables are located and two satellites – one in the center of the condo (the "bottom" of the U) where a PC requires good Internet access and one near the television.
I need the router to have at least two Ethernet ports and each satellite to have at least one Ethernet port. The system must work with some older Internet radios that use earlier Wi-Fi standards.
I also want a manufacturer who provides good technical support, even though of course I can always ask questions here!
The only Wi-Fi 6 capable device presently is an iPhone 11 Pro although I do not mind paying more for a Wi-Fi 6 system that may last longer.
Google Nest lacks Ethernet ports so I am not considering it. I am looking at Linksys and Netgear, and am open to other manufacturers.
I am looking for specific recommendations of things to consider and specific products.
