Simple solution that works for me and passed the rigors of time,
1- Click SETTINGS
2- Side the WI-FI to ON
Also under PC & Devices, which may not be necessary, I set DOWNLOAD OVER METER CONNECTIONS to OFF.
The bottom line is I have Wi-Fi connection to my CANNON PIXMA MX410, where I used the CANNON pushbuttons on the device itself to set the Wi-Fi communication to the NETGEAR ROUTER. The USER NAME and PW supplied by the NETGEAR can be found on the bottom of the device. I also did the same for my SONY BP S580 by using the SONY remote device. If you're missing any instruction manuals, all those downloads are available on the manufacturer's site.
