My cable modem is in the garage where the coax comes into the house, but my Wi-Fi router is in the attic for best house coverage. I have one CAT5 run to the attic, which has worked out so far, but now I need some LAN ports near the cable modem in the garage. What I have in mind is installing a simple non-Wi-Fi router coming out of the cable modem, and linking it to the Wi-Fi router in the attic.

Recently I saw a write-up on the Web about just such a lashup, which advised cabling a LAN port from the first (primary/garage) router to the other (sceondary/attic) one, setting the primary router for DHCP and turning DHCP off on the secondary. Ostensibly the primary router will assign IPs for both, including the Wi-Fi IPs on the secondary. Is this accurate, or is there a better way to do this? Help, please.
