No worries, I've moved it to the correct section. As DumaOS isn't OpenWRT you wouldn't be able to complete the setup as they've described it so you would need to contact them to see if there are any instructions you need to follow instead, you may not need it. Have you tried to connect to it to see if it works?
Also don't show your private key, I've removed the image for you.

Thanks, Fraser, that worked a treat. I knew it wasn't a proximity issue, because the R3 is 3 feet from the TV. Separating the bands and changing channels with a wifi analyser worked. 
Thanks.
