Earthlink always provides external ADSL modems. The supplied ADSL Modems use an Ethernet connection type - You will need an Ethernet card or onboard Ethernet Connector. Earthlink does not support internal or USB modems, but they can be made to work with Earthlink ADSL if you do not mind the extra effort on your part that will be required to setup and configure them.

If you've just recently gotten Earthlink ADSL service in 2006 the newest Modem is the ZyXEL P660R-ELNK Router for ADSL (also supports the LPV - DSL & Home Phone Service packaged bundle's ADSL2+ requirement) and the P660R-61 Router for bundled Home Phone and DSL service (aka LPV - Line Powered Voice and ADSL2+ DSL type). Both have built in PPPoE and both are preset to support 32 Private IP addresses (meaning up to 32 PCs) on the LAN if you just add a multi-port 10/100 Switch. The P660Rs appear to be fully functional Routers (all P660R versions). There is also a newer ZyXEL P660R-D1 that may be sent out in 2007. [Buying Advice: Don't buy a multi-port 10/100 Hub instead as the now very small price difference is not worth the overall performance difference when compared to a faster multi-port Switch]

Formerly a "one PC online at a time" ADSL Modem was given out known as the UHP Modem (since mid-summer of 2002 to the beginning of 2006) and if you joined back then the chances are you will have one of the 5 models of the UHP modems. There is a FAQ Section on the setup, care and feeding of these UHP modems here :

None of the current or early "Bridge only" or UHP ADSL Modems require that you install any Earthlink software to use the service. Early non-UHP Modems (Bridge Only Modems from earlier than 2002) do require some kind of PPPoE software and you can use what Earthlink offers for non-XP systems (WinPoET 4.0), or you can use the Built-in XP PPPoE software or you can even use the "free" RASPPPoE client from here or even a multi-port Router that has PPPoE in the Firmware. However, the current ZyXEL P660R Routers (P660R-61 or P-660R-ELNK) and all the previous UHP Modems do not require that you install any PPPoE software at all as PPPoE is built into all the P660Rs and the UHP Modem versions.

NOTE: If you are a long time customer and get a ZyXEL P660R (either type) as a replacement modem then you may have to change the VPI/VCI settings in the modem depending on your lines actual settings. The two choices are 0/35 and 8/35 (the 8/35 is an older no longer used for new installs VPI/VCI pair that was used in Bellsouth areas). Details here: What are the VPI/VCI modem settings for Earthlink ADSL lines?

The UHP modem is the first step towards simplifying DSL connections for Earthlink users. Since there is no PPPoE software that is needed on a person's computer, they'll set their computer with the default ethernet settings to get a connection established with the modem.

Earthlink started shipping these out with their self-install kits at the beginning of the summer in 2002.

The Pro's are that pressing the reset button on this doesn't blow up your DSL modem like the other ones and sets them back to the default settings you got when you received your modem. PPPoE is handled by the DSL modem and there is no need for PPPoE software like winpoet/enternet/raspppoe.

The Con's that I have seen is that only 1 computer can access the internet at a time. The device acts like a NAT router in a way that you can have multiple machines networked without a wide-open view from the outside world, but the downside to this is that these machines can not be on the internet at the same time. If a second machine tries to access the internet, a login page will appear and will ask if you want to boot X user offline after entering your username and password. If you want multiple machines to access the internet simultaneously with DSL you will have to set the UHP modem into bridge mode and set up a router to run PPPoE.

Overall, I believe this is a good thing because it can still be set to run in bridge mode and fucntion just the same as every other DSL modem thats out there now. It's not going to replace your router, but you can still use one in bridge mode. This is a definite plus for the single computer user who doesn't like PPPoE software on their machine.

In the self-install kit that you receive, there will be some microfilters, an AC Adapter, a Y Splitter, a POTS wire, an ethernet cable, as well as the UHP modem.

There are two types of modems that have been sent out, however, the Broadmax will most likely be the standard for future shipments. The Dataquest modem is one of the other modems people may have.

HTTP Interface: Yes
Telnet Interface: No
DHCP: Servers up to 10 IP's

Both modems have a built in diagnostic page. If you are unable to browse the web, this page will appear no matter what web site you try to load. On the Diagnostics page you will see several entries with either a PASS or a FAIL signal. Each entry also has a "help" link that users can click on for possible reasons why it could fail.

Section #1, Test your Connection to Earthlink.
*Test PPPoE server connection
*Test PPPoE server session
*Test Authentication with Earthlink
*Test the assigned IP address

Section #2, Test your Earthlink Internet Connection
*Ping Default Gateway
*Ping Primary DNS Server
*Query DNS for "highspeed.earthlink.net"

If all these tests pass, you can then close the window and open a new one to browse to whatever page you want. If they do not pass then ther is a "Help" link beside each Pass/Fail section which links with possible reasons why something would fail with step-by-step instructions on what to do.

By default, when you receive the modem, it comes with the default settings of a blank username/password, VPI/VCI set to 0/35, and the Unit is set to UHP mode (DHCP/PPPoE/NAT).
On the broadmax modem there are four lights. Below is the lights, and what various steps there are to them.

*Sync/PPPoE: Flashing Amber means that it is trying to sync up. If it keeps flashing after 5 minutes, you have no sync. Flashing Green means that you have sync and it is establishing a PPPoE connection. Solid Green means that you have sync and you have a PPPoE Connection.

*LAN: Solid Green if there is a detected ethernet connection. Blinking Green if there is traffic.

*WAN: Flashing Green whenever there is internet traffic. Otherwise, the light is off.

*Power: Solid green if powered up successfully. If the self-test diagnostics fail, the light will be off.
On the DataQuest modem there are 5 lights. Same as with the broadmax, except the Sync and PPPoE are their own separate lights. The lights are identical as far as character and diagnostics. The Sync light is flashing yellow when training, solid yellow when sync. PPPoE is flashing green when establishing a connection. Solid Green when successful, off when unsuccessful.
Both modems contain a LOG file. To view it, open up the modem's IP in your browser (, Click on the diagnostics tab, and click on View Log File. You can click on the "Save Log" file and save it as a txt file to your desktop. This log has a lot of great info for the user, and for a technician if there was a problem.

It will show the different events (System Start, Line Connect, Authentication Process, PPPoE connection) as well as the details on each. You can read and see for yourself the info but the more important section is the "ADSL Line Connected" event. It lists the following:
Resync Count
Downstream/Upstream Bit Rate
Downstream/Upstream Capacity Occupation (in percentage)
Downstream/Upstream Noise Margin
Downstream/Upstream Attenuation
Downstream/Upstream Output Power

In the PPPoE (PPP Connected) event it will also show the resync count, the Local IP, Remote IP, and the DNS IP.

Finally, to upgrade the device, place in your browser and load up the page. On the top of the page is an Upgrade tab. Click it. There's an upgrade button near the bottom of the page that you can use to upgrade your UHP modem.

This is the quick and dirty guide to the 2 UHP modem devices. One thing I forgot to mention is that it uses a technology which will force a page to come up no matter what web site you visit, if there is a problem. I.E. the login page to enter your email address and password, or the diagnostics page if you can't connect. Once all things are successful, you can continue to browse to whatever you want to.

I have had the opportunity to personally see these devices and I'm pretty impressed. The interface is very easy to manage and things couldn't be much simpler for the average user. Even for the advanced user, the log file and the ability to use PPPoE on the device without software is a plus, and also, it doesn't require that all the networking equipment you had to be thrown away since you can set the device into a standard bridge mode.

Although Earthlink's technical support may tell you otherwise, you can basically use almost any DSL modem with Earthlink's DSL service, USB or ethernet, internal or external--provided that it is configured with a VPI/VCI of 0/35 or 8/35. And yes, you can use Earthlink's WinPoet software (or any other PPPoe software) to log-on.

First you need to telnet to your Zyxel ADSL modem. Go to Control Panel => Network. Select the TCP/IP entry for your ethernet card from the list of network components installed.

Click the properties button, then click the IP Address tab. Activate the "Select IP Address" button and enter 10.0.0.x (where x is a number between 2 and 255) for the IP Address and for the Subnet Mask. Click OK and reboot your computer.

Now open a DOS window and type telnet at the DOS prompt. The command line interface for the modem will appear. Enter mspgzyx as the password. (NOTE: Earthlink currently ship the Zyxel modem with this IP address and password, which may differ from the information provided in the setup instructions).

Some useful information about your connection can then be viewed. Menu 24.1 gives system status info, such as line status, upstream and downstream sync speed. Menu 24.8 starts the command interpreter mode. At the command prompt, type wan adsl chandata to determine if you're on fast channel or interleave channel mode. Type wan adsl line far or wan adsl line near to get your upstream or downstream line noise margin and attenuation. Type exit to quit command interpreter mode.

WARNING: It is not recommended that you add or modify any data in your modem unless explicitly instructed to by Earthlink technical services. It is important for you to know that telneting to your modem can void your modem warranty.

Normally, yes. However, if the Zyxel 642M-11 modem you have was shipped to you by Earthlink, it cannot be used a router. The firmware used by Earthlink prevents that functionality.
