Name resolution across routers - Possible?

I have two linksys routers, one being a cable modem router and the
other a wireless router. A couple of machines in the house are
wireless, and the rest are hardwired.

Everyone uses the cable mode as their default gateway, and they all
share the 192.168.1.XXX address space.

Machines on the wired portion can see each other by name, but those on
the wireless (or vice versa) cannot. I've resorted to static IPs and
hosts files, but I'm wondering if there's a better way short of going
to a broadcast protocol like NetBEUI or installing a server machine
with DHCP and DNS.

Is there anything I can do so that everyone can have dynamic IPs but
still see other by name across the two different routers?

If you need any more info, just let me know!

Thanks,
Dave

Oh neato. A mystery question. Well, Linksys doesn't make a cable
modem router combination that's not wireless. Therefore, I can only
guess that you have a Linksys cable modem but no router. That would
be a BEFCMU10. Linksys makes several wireless routers so it's
probably a BEFW11s4 or a WRT54G. How close did I guess? Do I get a
gold star if I guess right?

A couple means two, so I decode that to mean that you have two
wireless machines and probably two or more hardwired machines. More
gold stars please.

Well, that's odd because the cable modem doesn't use the IP address
for routeing, only management. What's the IP address of the default
gateway and which box has the DHCP server?

>Machines on the wired portion can see each other by name, but those on

I'll assume that they're all using Windoze XP Home. Failure to "see"
each other can be due to a variety of causes. The usual culprits are
failure to configure the Windoze Firewall for "file and print sharing"
on the exceptions tab or different workgroup names.

Another common problem is that if by some chance, your wireless router
is a WRT54G, it has a feature called "access point protection" located
on the Wireless -> Advanced setting page. It's really client radio
protection and will keep wireless clients from seeing each other.
Uncheck the box.

"Resorted"???? Does that mean it works with static IP's?
Just for fun, put things back the way they're suppose to be (i.e. DHCP
and no NETBEUI) and try to ping each machine. If you can't access by
NETBIOS name, try it this way:
Start -> Run -> cmd <enter>
\\NETBIOS_NAME
or
\\192.168.1.xxx
Both should show a list of available shares.

Well, that largely depends on where you have the clients plugged in.
If you have the wired clients plugged into the first router (the one
that may or may not have a cable modem inside), then those clients
will never see the wireless clients because they're going to them via
the WAN port on the 2nd mystery router. You can open up one machine
by using the DMZ feature, but not the others.

>If you need any more info, just let me know!

That's an understatment.

Hint: If you don't supply model numbers, IP numbers, exact
description, and details, you're going to get a vague and probably
insulting answer (like this). If it helps, try to organize your
question like this:
1. What problem are you trying to solve?
2. What do you have to work with?
3. What have you done so far and what was the result?

You should only pour on the sarcasm when you're correct :-) Linksys
makes a cable modem router that's not wireless, called the BEFSX41,
which I have one of, and the wireless one BEFW11S4 which I also have.

So, the cable modem is plugged into the BEFSX41 and the BDFW11S4 is
plugged into it. All are on the same subet. The BEFSX41 acts as the
DHCP server for both sides of the equation (thought I've tried it both
ways with no change)

The problem I am trying to solve is that I'd like the wireless clients
connecting via the BDFW11S4 to be able to resolve names of clients
wired to the BEFSX41.

Hope that's clearer.

Thanks,
Dave

Do I still get a gold star for guessing the BEFW11s4?

>Linksys

I went looking for it on the Linksys web pile and didn't find it. The
thumbnails in the product selection page don't say cable modem but the
product page does. Typical Linksys attention to detail.

Anyway, I shouldn't have to guess your hardware and softare.

>which I have one of, and the wireless one BEFW11S4 which I also have.

I think we can both agree that you have one of each type. I'll leave
the number of client computers and their corresponding hardware and
software to the imagination of the reader as it's not really relevent
at this point. I'll assume Windoze XP Home because nobody really
wants to admit that they're running Microsoft products.

Well, there's only one way to plug in the BEFSX41. Cable port goes to
the cable.

However, there are two places to plug in the wired clients. You can
plug them into the BEFSX41 LAN ports or the BEFW11S4 LAN ports. Which
way do you have it wired?

The BEFW11S4 can be configured in two different ways. The WAN port of
the BEFW11S4 can go to one of the LAN ports on the BEFSX41. This
results in what's called "double NAT" and causes the problem your
having.

Another way is to run the BEFW11s4 as an access point instead of a
router with the ethernet cable going from a LAN port of the BEFW11s4
to a LAN port of the BEFSX41. That's the way you should have it
configured.

My guess this is a home system so isolation between the two routers is
not a requirement.

Trying to decode your configuration is a bit tedious tonight (my foot
in a bucket of warm water thanks to a slight mishap while hiking
today) so I'll just tell you what to do to get what I'll guess you're
trying to accomplish, rather than figure out some complicated way to
get NETBIOS browser election broadcasts to go through a firewall.

To convert your BEFW11S4 into an access point, perform the following
ritual:
1. Setup the IP address of the BEFW11s4 to something that does NOT
conflict with any other device. If the BEFSX41 is 192.168.1.1, then I
suggest using 192.168.1.2.
2. Turn OFF the DHCP server in the BEFW11s4.
3. Do not connect anything to the WAN port. The WAN port is not
used. Nothing goes to the WAN port. The WAN port is not needed.
(This is the most common screwup so I thought repetition might be
useful).
4. Connect an ethernet cable between a LAN port on the BEFSX41 and a
LAN port on the BEFW11s4. You might need to use a crossover ethernet
cable, but I don't think so. If the BEFSX41 has an MDI/MDI-X switch,
or "uplink" port, use it. Check that the wiring is correct by
observing the front panel lights on the respective ports.

You now have an access point instead of a wireless router. DHCP will
be assigned from the BEFSX41 to both wired and wireless clients. If
setup correctly, Windoze networking should be transparent on both the
wired and wireless clients.

>The problem I am trying to solve is that I'd like the wireless clients
>connecting via the BDFW11S4 to be able to resolve names of clients
>wired to the BEFSX41.

No, that's where you were stuck. What you are trying to accomplish is
how to get your wired and wireless clients to talk to each other via
Windoze networking through two boxes.

>Hope that's clearer.

A little bit, but not much. In all seriouslessness, your description
of both the problem and your setup was very vague and difficult to
decode. Hint: If you don't have any numbers in your question,
you're leaving out quite a bit of important information.

Now, about those gold stars you owe me...

Made by various contract vendors in China. Linksys just adds their
name, instructions, firmware, sales, and support. I can supply the
names on some of these if you're really interested.

Here's the original description:
"I have two linksys routers, one being a cable modem router and the
other a wireless router."

Note the word "modem". Which one of the afformentioned has a cable
modem built in?

Linksys does sell the WGR-200, which has a cable modem, router, and
wireless built in. However, the subsequent description clearly
indicated that there was no wireless in the unit. Therefore, none of
those listed would qualify. Sorry, no gold star for guessing the
correct model number.
