Seeking help with multiple router setup

Having trouble with multiple router setup.

I have a LAN connecting 4 Windows PCs and accessing the internet through a
router. The setup is this:

The cable modem directly connects to the first router and gives it a dynamic
IP.

First router has a LAN IP of 192.168.0.1.
It runs as a DHCP Server.
It has Internet Port Subnet Mask of 255.255.248.0
It has LAN Port Subnet Mask of 255.255.255.0
It connects to 2 devices: 1 computer and a second router, both of which
receive an IP in the range 192.168.0.2 - 192.168.0.254

So the second router gets a WAN IP of 192.168.0.XXX
and has a LAN IP of 192.168.1.1
It has a WAN IP Subnet Mask of 255.255.255.0
It has a LAN IP Subnet Mask of 255.255.255.0
It has a default gateway of 192.168.0.1 (the first router)
The other 3 computers connect to this router, and get IPs in the range
192.168.1.100 - 192.168.1.254

Here're my problems:

1. On the Windows Network, the computer linked to the first router cannot
see any of the computers linked to the secound router.

2. The 3 computers linked to the second router cannot keep a stable internet
connection, and I don't think it's because of the dynamic IP assignment
(they disconnect much more often than dynamic IP changes).

One router is an old Linksys. The other is a new Netgear. Both are 4-port
with Wireless 802.11 (b and g). Using the Netgear as the first router (i.e.
the one directly connected to the cable modem) seems to make things worse.
That is the setup I described above.

Should the two routers have different subnet masks? Any suggestions or
related networking info would be appreciated.

I believe you need to set the second router to the same domain as the
first. Just change it to 192.168.0.2. Don't let it get it's ip from
the first router DHCP. I belive the default ip range for linksys is
the 192.168.1.xxx range. You may also need to turn on the RIP
protocol for everything to work better.


My setup

First router 192.168.1.1 subnet mask 225.225.225.0 DHCP enabled
Second router 192.168.1.2 subnet mask 225.225.225.0 DHCP disabled

First router only should be DHCP server. Second router DHCP should be
disabled. On first router connected to Internet should be set as
gateway. Second router should be set as router.


Maybe somone more knowledgable will correct me if I'm wrong, but I
believe this is the way it should be.

Does that mean that computers connected to the second router must have
manually set IP addresses?

That's just asking for trouble, IMHO, because the second router might
still NAT (unless you can turn that off).

Sorry I can't type very good should be 192.168.1.2

And it works for me through a wireless bridge.

No they will get their IP from the First router.

My setup

INTERNET

Motorola SB4220 Cable Modem into WAN port on router

BEFSR81 Linksys router set to gateway mode Lan IP 192.168.1.1
Subnet Mask 255.255.255.0 DHCP enabled

WAP54g Wirles Access Point into router Lan port.
two Win 98 Computers into Router Lan ports

WET54G Wirles Bridge Downstais into

BEFSR81 Linksys router Lan port
Static IP 192.168.1.2 subnet mask 255.255.255.0
Set to router mode DHCP Disabled

Two other win98 computers plus 2 winxp laptops. Into second router's
lan ports

All computers get theri ip address 192.168.1.xxx from the first
router. It is setup as a DHCP server to give out address in the .100
to .150 range.

hope this helps.

I'm not sure about the netgear but the linksys doesn't NAT in router
mode only in the Gateway mode.

The windows network doesn't like to cross domains

computers on 192.168.1.xxx have a hard if not impossible time trying
to see a computer on 192.168.2.xxx the only exception I've seen is
that I can see my cable modem at 192.168.100.1 and my computer is
192.168.1.110. But the cable modem is going into the WAN port on the
router, so maybe that is why my computer can see the modem.

Netbios isn't routable. TCP/IP is routable. End of story.

Gene, I was wondering what happened. Did you get it working?
