I'd use the second router as a WAP instead. How to do that is either in the product manual (most don't document it) or you can google the following for articles which you read till you find the one you understand.
"How to use a router as a WAP?"
Good afternoon: My AT&T Gigapower Arris NVG599 Modem / Router is in the main living room of the house and I get great reception, Wireless speeds of up to 400mbps. My AT&T Digital Life Box is in my computer / XBOX / room and I would like to set up my Netgear N600 as a Bridge so that I can Ethernet into. Maybe i am using the wrong term. I would like to make the Netgear N600 an access point so that I can Hard wire into its ethernet ports. Can you Gentle woman/man point me in the write direction please? thank you for your help.
