The second module kept disconnecting from the main router rendering the whole mesh unusable. Possibly due to the fact that I bought refurbished devices this could be the reason for this, but their user interface is also pretty terrible, based on the overall ease of setup and performance I decided to return them. In fact, I bought a mesh extender through a wifi6 router, both from Netgear, which work 10x better than this particular solution. You should probably buy a new one that can give you better performance, but I don't recommend refurbished units.
