I think this one I had gave a different problem though, SRS (and my 2 AP towards either end of the wired part covers most well). The camera is a wired only POE one so it needs to plug into a wired port. I didn't want the hassle of running a cable into the bedroom so I took this route as I had an access point that would do it.

The access point in this client mode connects to the wi-fi in the same way as a computer or mobile device would do. Instead of its port connecting to the LAN, it becomes a sort of wired extension of the wi-fi which I can plug my wired only camera into (well in this case, indirectly as I also need to inject poe). Maybe there are other ways but it's one way of getting a wired only device online where there is only wireless available.
