It is. The TP-Link 702 can be programmed to be an access point (connect to an existing wired network and create a WiFi network), or a router/access point (no existing network - create a WiFi network with router facilities), or an adapter (connect a non-WiFi device's Ethernet port to an existing WiFi network), or a bridge (connect to an existing WiFi network and provide another WiFi network - though I have not managed to get that function working, it would be useful to create a temporary guest WiFi network with limited range).
I use the router/access point function to create a temporary network to a non-networked HDR-FOX, so I can access the WebIF with my iPad when visiting the outstations. Suitably configured (it saves the config in NV), all I have to do is plug the 702 into the Humax's Ethernet and USB sockets - and bingo I have access (no hardware Ethernet port on an iPad). Brilliant.
