need help configuring wireless router on network with existing router
Posted by cappy on September 17th, 2004


I just purchased a Netgear WGR614v4 wireless b/g router. It has an
integrated 4-port switch. Supports RIP, all latest bells and whistles.

I am having a hard time configuring it on my network.

My basic setup contains a cable modem currently plugged into an older
hard-line Linksys BESFxxx cable/dsl router, which has an integrated
4-port switch. One machine is directly connected to this router's
switch, and then I run a line to another 8-port switch in another part
of the house, where another machine (and other various devices like a
ReplayTV, Rio Media Player, etc) are connected. I have a Dell Latitude
D600 laptop (Centrino with integrated G wireless) that I would like to
be able to use via the new wireless router.

The problem is that I cannot TOUCH the old router connected to the
cable modem. It is used by my wife for her business and she won't let
me near it, though we share the internet connection (I screwed things
up a bit in the past, ) So, I need to make BOTH routers work on
the same network, and cannot figure out how to configure the wireless
router correctly.

Here is the basic setup. Sorry for the multiple lines but I wanted to
make sure that users with different fonts could see it correctly:

route 1:

cable modem <--> Linksys router <--> machine 1

route 2:

cable modem <--> Linksys router <--> 8-port switch <--> [other
devices]

Note that the cable modem and router listed above are the same in both
routes.

I currently have the wireless router plugged into the switch like so:

Linksys <--> switch <--> Netgear wireless router <- wireless -> laptop

The laptop can SEE and configure the Netgear router just fine. It just
cannot get to the internet or LAN.

I have all devices on the original (non-wireless) network set up to
use static IPs.
All devices are on the same subnet of 192.168.1.xxx.
The Linksys router IP is 192.168.1.0.
The Linksys router IP is used as the Default Gateway IP for all
devices on the original network (obviously).
The Netgear router IP I manually set to 192.168.1.20, from a factory
default of 192.168.0.1.
I enabled DHCP on the Netgear for the laptop since all other machines
and devices on my network have static IPs.
I gave the Netgear a DHCP address range of 192.168.1.21 -
192.168.1.23.

The laptop gets an address via DHCP of 192.168.1.21 from the Netgear
with no problem. I can also login to the Netgear router via wireless
without problem.

I am not sure which port I should use to connect my Netgear router to
the 8-port switch. I have tried using both one of the
auto-uplink-sensing integrated switch ports and the WAN port. But the
laptop can never see anything else on the network nor can it connect
to the internet.

Currently I have the Netgear router connected to the switch via the
WAN/internet port. I have manually configured the IP of the Netgear
router's WAN port to be the same as that of the Netgear router itself:
192.168.1.20. I have also tried 192.168.1.222. I set the Default
Gateway IP for the Netgear router's WAN port to be the address of the
Linksys router: 192.168.1.0. I use the same DNS addresses as all other
machines on the network.

Do I need to use RIP or static routes or something? I am completely
clueless when it comes to networking, even though I have been a SW
engineer for years. Sorry for the long post but this is driving me
nuts!

Thanks for any help -

OK, while a switch is a little more intelligent than a simple hub, it may
not be active enough to allow two routers to effectively cooperate, if the
switch is between them. The PROPER solution would be to replace the Linksys
router. But if you can't do that, Try this:

Cable Modem <> Linksys Router <> Netgear WGR614 (any LAN port) <> 8-port
switch <> [other devices]

Then run your network wizard on your laptop and set it to connect to the
Internet through another computer. That computer in this case would be the
Linksys Router, and the Netgear should simply pass the packets back and
forth wired and wirelessly between laptop and Linksys Router.

Of course, If you put the Netgear router in front of the switch, you might
have to change all your static IPs on the devices connected to the 8-port
switch.

I suspect you've got a real headache on your hands unless you can convince
your wife to let you replace the Linksys router. -Dave

Hmmm... something is haywire here somewhere down the line causing that
NetGear router to get dreadfully confused...

My suggestion to you would be to first reset the NetGear back to it's
factory settings to start again from scratch with a clean slate... next
keep the WAN side configured by DHCP... and then set the LAN side to
use 10.100.0.1

The NetGear router should remain connected to the switch via the WAN
port... allow your wireless client to be assigned by DHCP from the
NetGear router as normal.

See if that works...
