need advice

am using AV500 powerline now
previously connected to D-Link DAP-1360 simple wifi AP and recently the AP give weird prob
thinking of buying an adapter with wifi signal extender rather than buying another AP as replacement
eyeing on TPLINK TL-WPA4530
based on my reading, seems like it can connect with my existing AV500 pwerline and by its own can generate wifi signal
so I can save one power outlet (no need power for AP and at same time for powerline adapter)

is the above good choice?
or still better to use dedicated AP like my previous D-Link to enjoy better connectivity?

please share ur view....tq
