I use these when the device needs an ethernet connection but cabling is a hassle. We used to call them bridges, but it seems like lately my Silicon Valley colleagues decided to call this feature "client" since they started using the term "bridge" to mean connecting two networks . Well, times are changing. You will do both. I would not use them as an access point. There are a million better options out there. But for connecting and working with clients, they are one of the best (or only) options available. If I answered all your questions, I definitely recommend this review. Many Thanks
