Netgear DM111PSP Modem Setup for Brand X Internet

The Netgear Modem is a sturdy, inexpensive high performance modem. The purpose of this device is to terminate your connection. It is usually used in combination with a Wifi Router, which is a connection sharing device.

The full manual for the Netgear modem can be found on Netgear's website at

Installing your modem

if you obtained your modem from Brand X Internet, it is probably already configured.

Do not reset it to factory defaults. This will undo the programming we did.

Plug a telephone line from your modem to the wall jack.



For normal setup, you should run an ethernet cable from the ethernet port (see diagram above) to the input on your route or computerr. No configuration is necessary.

That's it, you are done. Setup is complete. Your next step is to check the modem lights and make sure you have a good dsl signal.

Modem Lights

Once you have set up your modem, the first thing to do is to check the lights.

We are most interested in the "DSL" light (see diagram).

This light should be solid green. This means you have a good DSL signal. Your next step is to set up your router. We have separate instructions for most types of routers. If you do have a good DSL signal then you are almost certain to have success setting up your line.

Blinking green is bad. This means you do not have a good DSL signal.



Power: You have power.

Ethernet: something is plugged into the ethernet jack.

DSL: A solid green light means you have a DSL signal. Blinking means it is trying to sync up. Light off means no DSL.

Internet: This light should be off. If you see a light here, your modem is misconfigured. See notes below.

If you do not have a good DSL signal, do not bother trying to set up your router, it won't work. A good DSL signal is an absolute requirement to get your DSL working

If you do have a good dsl signal, then you are done. Your next step will be to set up the router. You will need to refer to the router instructions. You are done with setting up the modem..

What do I do if I don't have a good DSL signal?

If you do not have a good DSL signal, please do not immediately start reconfiguring everything. That won't help. DSL signal is a hardware issue, not a configuration issue. Check your cables, see if there is another phone jack, make sure you have a good phone card, but do not reconfigure the modem.

A good DSL signal is an absolute requirement to get your DSL working.

If you can't get a DSL signal, please let us know at Brand X Internet, and we wil see if you need some help with cabling up the jack. In Verizon areas this is often necessary because Verizon doesn't guaranty that the dsl line will be connected to a jack.

Explanation: Verizon says that the dry loops are delivered to the address, not to the jack. They might install to your jack, or to a jack in a neighboring apartment, or even to some wires hanging out of the wall someplace. Some Verizon installers will test to your jack, which eliminates the problem. Others don't even come out, so it's just luck whether the line works.

If someone needs to hook up a jack, and complete the circuit, we can do this. Just let us know.

If your line is installed and you can't get sync, then call us at 310 395 5500.

What do I do if I have a RED light on the Internet light?

If your modem is set as a modem only (no router) then the Internet light may go red.

This doesn't mean anything, except that the dsl light is probably not solid, and you probably don't have a good dsl signal.

The DSL light is much more important.

If your Netgear device has the router enabled, then the Internet light means you are not getting online.

In most cases you can ignore this light and concentrate on the DSL light.

Configuring the Netgear Device as a Modem Only

Note: we normally deliver modems preconfigured. These configuration instuctions are provided in case you need to reset your modem, or in case you have purchased the modem from some other source and need to set it up.

Netgear modems can be configured as modems or routers. These instructions will show you how to disable the router so that the device can operate as a modem only.

We generally recommend to set the Netgear modem this way as a modem only, because this allows you to have your own separate router. The Negear is a good router, but it doesn't have WiFii. If you want WiFI you need a separate WiFI router.

Connecting to the Device

Connect a telephone cord to the modem, and then run an ethernet cable from the modem to your computer.

Now open a DOS window. This means, from the start menu, click, then in the search window, type "cmd" and a DOS window will open.

In the DOS Window, type "ipconfig /renew" as I have done below. This will reset your connection and get a new ip address of for the ethernet adapter, as showin in the picture.

If you have WiFI, you might have to disconnect it to get this to work because the computer is easily confused by having more than one internet connection.

If you are on a Mac, or if you have trouble getting the DOS window to work, just cable things up, turn off your WiFI, and restart the computer. You should now be connected to the modem.

Open Web Browser

Point your web browser at the address

The netgear device should ask for a username and password, as shown below. The standard username is "admin" and the password is "password".

This should get you into the configuration screen, as shown in the picture below.

Ignore the "autodetection" and "wizard", we don't want those.

From the menu on the left side, towards the bottom, in the section called "Advanced" is an option called "Device Mode". Select that.

After you have selected "advanced-Device Mode" you should see the "Device Mode" screen, as shown in the next diagram. It is set to "Router/Modem". Change it to "Modem (Modem only)", as shown below. Click "Apply" and the modem will reset.

The modem will take one or two minutes to restart. You are done. Your Netgear device is working as a modem only.

Configuring the Netgear Modem to Enable the Router

We normally deliver the modems preconfigured with the internal router disabled. They are easier to set up that way, and you can use a real WiFi router instead.

However, you can set them up either way.

If you want to configure the Netgear as a router, we have a separate instruction sheet for that. Referring to the instructions above, you can enable router capabliity by selecting advanced -> device mode -> modem/router.
