Linking Routers

I have a broadband connection into a modem/router which is connected directly to
my desktop PC . I then have a wireless router connected to the modem/router.
I use the wireless connection for my laptop and want the share files with my
desktop but cannot.

The LAN port IP address of the modem/router is 10.0.0.2, the port IP address of
the wireless router is 192.168.2.1 and have been told that I must change at
least one of these. I have tried various combinations but am getting nowhere.
Can anyone suggest a solution?

The wifi router would have been better if it were a Wifi Access Point
(AP). In any event:

The modem/router has an IP of 10.0.0.2 leave this as is, ensure the
netmask is 255.255.255.0 Enable DHCP on this device with range
10.0.0.20-254.

Then plug either pc into the Wifi router login and set it's IP as
10.0.0.3 netmask 255.255.255.0 Login again using http://10.0.0.3/
Switch off DHCP and set the default gateway as 10.0.0.2

Then configure the highest level of wireless encryption that is
supported on both the router and the laptop - WPA2?

Then connect it all up as you diagrammed above. On the desktop do start
> run > cmd > ipconfig /all and find out what IP address it has - it
should be 10.0.0.X (x=20 or greater)

Then do the same on the laptop and see if it gives you a 10.0.0.X IP
address where X is 20+

If this works then from the laptop do ping (Desktop IP Address), if
you've a response then ensure the Workgroup is the same on the Desktop
and Laptop, and you've enabled Sharing on the bits you want to share

Whenever reconfiguring the router/Wifi devices and restarting them it is
best to restart the connected PCs. It's braindead compared to unix/linux
but is best advice.

Any other devices that you don't want the IP Address to change like
network printers, NAS devices, etc. then give them a fixed address
10.0.0.4 - 19

I guess that you have the WAN port on the wireless router connected to the
modem/router. On the wireless router, if you:

1. Release the WAN DHCP lease.
2. Unplug the lead connecting the wireless router to the modem/router at
the near end.
3. Change the LAN interface IP address to an unused address in the range
configured on the modem/router, and the subnet mask to the same as on
the modem/router. Ideally, the address should be outside the DHCP pool
configured on the modem/router, but in practice it rarely matters.
4. Disable the DHCP server.
5. Plug the lead from step 2 into a LAN port (not back into the WAN port).

Then you effectively convert the wireless router into an access point (and
network switch), and the laptop should appear on the network the same as if
it was plugged into the modem/router like the desktop PC.

Tony & Alex - no joy I am afraid.

I tried re-set the wireless router (Belling) to 10.0.0.3 (from 192.168.2.1).
Did the save and re-boot (then off/on etc...) but could not then get back in
with either address.

I thought then that I might change the settings on the modem router instead.
First I set the address of the wireless router to 192.168.2.2 and it accepted
that OK. I then tried to re-set the address on the modem router to 192.168.2.1
(from 10.0.0.2) but the same thing happened as before. I did the save and
re-boot but could not get back in with either the old or new address. I have
re-set both to the factory settings. Am I destined to share files via
floppies?

Can you expand on that?

My Linksys WRT54G which is a combined router/WAP needs replacing - a new
one is £42.

A WiFi Access Point is from £32 to £54 - apart from saving £10 what are
the advantages? I was just going to get another WRT54G or equivalent.

A WAP plugs into an existing router and connects wifi clients to the
existing router not to itself - it's transparent. It has relatively few
modes; WAP, wifi/WDS repeater, wireless bridge, etc.

A combined router/wifi is a router and it will usually connect wireless
clients to itself. Whether it can be configured to just act as a WAP and
not a router, and so pass wifi client requests to the other
modem/router/gateway is the question the OP asked and I'm still
considering.

The router portion is much more complex because routers essentially pass
packets according to their configured rule sets. This is further
complicated by the fact that the router will also probably do DHCP which
hands out IP Addresses, DNS and Default Gateway routing info to
connecting clients. Get any of this wrong and it Won't Work.

I currently like the Netgear and Buffalo WAPs.

OK, that's useful.

With the Linksys I turned off DHCP and connected it to my main router (a
Draytek) via Cat5 and then used it as a dumb switch with a built in WAP.
Assuming any wireless router would work in the same way there doesn't seem
much point in saving a few pounds just to get WAP functionality - you
pretty well get the dumb switch bit free.

Yes. Provided the dumb switch talks on the same IP/Subnet/Netmask as the
main router. If it doesn't you may have a problem...

Any wireless router can be used as an access point plus switch, by disabling
the DHCP server, connecting a LAN port to the rest of the network, and
simply ignoring the WAN port.

In the past, a four port wireless routers with an Ethernet WAN port was
cheaper than an access point, so you effectively got the switch for less
than free .

The only disadvantage is that access points generally support various modes
of operation - eg using two to wirelessly link two wired networks together -
whereas wireless routers do not.

The only problem is that you won't be able to configure it without
configuring a suitable address/mask on a computer. Everything else happens
at layer two, so IP configuration is irrelevant - just as an unmanaged
switch has no IP configuration, and a managed switch only needs it for
management.
