Extending WiFi by way of a second modem

I want to extend WiFi service from the main house to the guest house. I have enough cable and a second modem. Would someone who knows this subject have a look at my checklist? Here's what I plan to do:

Primary Modem 1 - Main House
* Copy security settings
* Make sure DHCP is ON
* Set channel to between 1 and 6

Secondary Modem 2
Make sure it has the same SSID and password as Modem 1
Turn DHCP OFF
Set channel to 11

Connections - Modem 1
Internet IN to WAN port
Cable OUT of say port 1

Modem 2
Cable IN to port 1

Is that correct, have I missed anything?

Thanks - rev

Do you mean ROUTER instead of modem? The setup seems to be correct, but you'd use routers, not modems.

The primary router channel should be 1 OR 6 for 2.4GHz. 1, 6, and 11 are the only non-overlapping channels.

Is the cable between the routers a crossover cable? If the ports are not auto-sensing, you may need to get a crossover cable (or adapter) instead of a regular patch cable. You didn't post any hardware info, so I can't say for sure.

Thanks.

>Do you mean ROUTER instead of modem?
These are both definitely modems. Isn't a modem also a router?

>Is the cable between the routers a crossover cable?
No, just a CAT5e normal internet cable

No. Some modems have a built-in router, but modems and routers are different things. Most consumer-based routers also have built-in switches for additional ports.

That's a "patch" cable. Unless the ports are auto-sensing, you'd usually need a crossover cable going between routers/switches.

So which part of my checklist will/won't work?

If they are modems instead of routers, that could be the problem. Also using a patch cable instead of a crossover between routers. Many newer router/switches are autosensing, though.

It might help if you listed actual hardware make/models.

To clarify, the first device can be a modem/router/switch combo, but the problem might be the second modem.

>but the problem might be the second modem
What might that problem be? I know this can be done with 2 modems and without a crossover cable because others around me have done it but at the moment there's no one who can help. The config page of one modems is in Spanish only which doesn't help.

>It might help if you listed actual hardware make/models.
They're both Telmex Infinitum modems but I'm not at the site anymore so I can't say what models, they're both different.

You'd also want to disable the modem part. The router might be using the modem part as the WAN connection. You don't want to use the WAN for the second router.

I can't help you with Spanish either.

So you didn't even try yet? Just try it and see if you run into problem.

I did try it but I found the config pages hard to understand, I wasn't sure if new settings were being saved, if I was making the right new settings, etc.

What IP did you set for the second modem/router? It should be in the same subnet, but out of the DHCP pool of the first router.

Ex. Router1 is 192.168.1.1 with DHCP pool of 192.168.1.100-150. Router2 could be at 192.168.1.2.

I'd just like to say a sincere, "Nanny nanny boo boo!" because it worked!

No problems of any kind, I connected everything per the checklist and the client connected immediately.

Thanks to all!

Hah! Nice. Glad it worked.
