Is it possible to go from one cable modem output and split the signal to
supply two different routers? (one hard wired and one wireless) Thanks

No. Connect the wireless router to one output of the wired router and
and configure the wireless router to function in bridge mode,
effectively converting it into a switch.

You'll need two routable IP's from your provider if you do it that
way, which might cost an extra monthly fee. You'll also need something
(like a hub or switch) to "split" the signal to the two routers.

Instead of all that, I would designate one router as the main router
and connect its WAN port directly to the cable modem. On the second
router, I would disable the DHCP server and connect one of its LAN
ports to a LAN port on the main router. Done.

Bill, I disabled the DHCP on the wireless and hooked it from Lan #1 on
the wireless to Lan #2 on the wired router, cable modem output goes to
the WAN connection on the wired router. It still doesn't work. My PC is
hooked to the wired router and cannot access the internet, but the
wireless router lets the laptop connect. When I click the wired router
shortcut on my PC desktop, it takes me to the wireless router setup.
It's like the wireless router bypasses the wired router and takes over.

Is this the picture?

Cable Modem Wired Router Wireless Router
----------- ------------ ---------------
(output) ==== WAN
                Lan #2 ======== Lan #1
                 =========================== PC, doesn't work
                                 ============ Laptop, works


I'm no expert, but I would have thought you'd want the
connection from Lan #2 on the Wired Router to go to the
WAN socket on the Wireless Router.

Are you sure your laptop isn't using your neighbor's wireless
router instead of your own?

Another wild guess: Maybe both routers are trying to use the
same local IP address, such as 192.168.1.1?
