I currently have a wired network using a cable modem and a wired
router. Can I add a wireless router by connecting the Ethernet cable
from the wireless router to a port on the wired router? I am trying to
gain flexibility in where I can place the wireless router while
minimizing the additional wiring. Thanks for the help.
Yes, you can simply patch the wireless router to the wired router over LAN
ports.
HOWEVER, what you don't want is TWO routers on the same network! You should
disable ALL routing functions on the wireless, including DHCP, NAT,
firewall, etc. That way, the wireless router simply becomes an AP (access
point) for wireless clients. They're simply dumped on the wired router for
DHCP, NAT, and firewall services. IOW, wired and wireless clients all share
the same services! This greatly simplifies configuration and avoids
confusion.
Of course, the other alternative is to simply replace the wired router w/
the wireless router, assuming the wireless router already comes w/ an
integral switch (most do).
Or you could reverse the process. Make the wireless router support all the
DHCP, NAT, and firewall services, and disable these functions on the wired
router (of course, you'd want to make sure the wireless router now had the
WAN to cable modem connection).
In a nutshell, however you do it, just make sure to have only ONE of the two
routers providing services!
