The camera wifi router in the different versions of the 802.11 standard (in fact the -802.11b- wifi but the 802.11g and n for higher flow rates). Well placed, the radio range is correct. It captures carefree throughout my house (a ground floor and two floors) with the router on the ground floor. Crossing the walls (stone 40cm home) is done with a notorious weakening but not prevent communication.
The ethernet router is efficient but not gigabit manual (therefore "limited" to 100 Mbps). This flow naturally enough largely in terms of internet access (which are still at much lower rate). It is also sufficient to process multimedia content. For example, I use a NAS and a squeezebox sound system (Logitech). Files are played carefree with or without passing through the radio interface.
Note that the router can be turned into single switch when needed. My installation example is a freebox (router) on the ground floor and a wireless router on the 1st floor (... or switch to the uninitiated so simple to strip cabler upstairs). In this case, be sure to connect the Freebox on one of the Ethernet ports and not on the port "internet" or "wan". Two solutions to the DHCP settings in that case, either the router's DHCP is deactivated to let the Freebox selecting addresses or it is ensured that the row address the Freebox can allocate is different from that of the router .
Configuration is done on a well-designed web interface. If it is better to have some concepts for any special network configuration
