This was all explained in my first reply in this thread. I've helped OP with this I don't know how many times already as he's had a few threads asking how to do this.While I would favour a simple task Beers, but having two devices running DHCP can and will cause issues down the line. Using a secondary router as essentially a WAP for the needs this is requesting would eliminate the second DHCP.
But regardless, since the information requested is not provided, then I see no sense in carrying on providing shot in the dark suggestions instead of sound directions when we know what devices are in play.
haha.
