2.0 General Questions

What should my modem signal levels be?

Receive/Downstream: -15dbmV to +15dbmV
Transmit/Upstream: 30dbmV to 55dbmV
Signal to Noise Ratio(SNR): 30dB or Greater

Note: If your power levels are out of range, it can cause packet loss, re-transmissions which will eventually lead to speed loss..Otherwise Signals have nothing to do with your speed.

What is the difference between a two-way and a one-way cable modem system?

The terms one-way and two-way are used to describe how your computer relays data to the Internet when you are using a cable modem. In a two-way system, your computer uses the cable modem for both sending (uploading) and receiving (downloading) data, allowing for high speeds in both directions. This eliminates the need for a traditional analog modem and phone line when using the Internet. You may still need an analog modem and phone line for other things, such as sending faxes.

In a one-way system, your computer uses the cable modem for receiving (downloading) data, but still requires an analog modem and phone line for sending (uploading) data. The use of an analog modem in a one-way system means that you cannot upload data as fast as you can in a two-way system. Even so, a one-way cable modem system gives you nearly all of the speed benefits of a two-way system. When you browse the Web, you usually upload a URL request or a mouse click. What you get in return is all of the text, graphics, and sound from the page you want to visit. That Web page data will all come back to you through the high speed cable network.

The availability of a two-way system is dependent on the type of coaxial network Charter Communications has deployed in your area. Traditional cable networks are designed to deliver television signals in one direction only and are made up entirely of coaxial cable. Modern cable networks use a hybrid of fiber optic and coaxial cabling (HFC) to provide two-way capabilities. Approximately 85% of all cable networks in the United States are one-way.


Will multiple users impact the speed of EarthLink High Speed Internet?

Bandwidth is shared from the neighborhood HFC node to your home, so it is possible for performance to vary depending on how many customers are actively using the system at any given time. It is worth noting, however, that this is also true for the Internet as a whole. The Internet is, in essence, one extremely large, shared network.

Are there any monthly bandwith consumption limits?

No! At this time there are no monthly caps for bandwith. Some users have reported receiving letters from their cable company warning them to throttle back on the downloading. If you receive a letter, please contact just_robert See Profile by instant message as per this thread.

There are however newsgroup caps of 5 GB per rolling 30 days as indicated here.

Will I get the same speeds from Earthlink as my cable carrier?

You should not notice any difference in service quality between EarthLink and your local cable company as EL provides the service over the same equipment as the cable company.

What to do when ordering Earthlink Cable in a TW area....

If you order Earthlink Cable by calling your local TW office, this probably doesn't apply. You'll also not be eligible for any promotions that Earthlink is offering.

If you order Earthlink Cable by either calling Earthlink or by using their website, after completing the order, CALL YOUR LOCAL TIME WARNER office to schedule your installation. Ask for the installation or service department and tell them you've ordered internet service and would like to schedule the install. Many people have reported waiting two weeks with no callbacks from TW. People who have called have been treated courteously and quickly. So, what's the harm in calling ?

Does EarthLink provide any packages with phone or other services bundled

Earthlink only provides the interface for your Internet experience. However with Time Warner Cable the Earthlink service will package into there All The Best, Surf N Talk, or Surf N View packages. The normal rates apply.

4.0 Earthlink Pwd. by Comcast

What are the advertised speeds?

Earthlink subscribers inherit the Comcast speeds which are typically 6000/384.

This may vary based on your location.

What about my Comcast email?

After you initiate the switch from Comcast to EarthLink, your Comcast email will be nuked and all messages will be deleted and access shut off to the account.

Where is EL/Comcast available?

Check out this EarthLink page for up to date availability status.

What's the ordering process like?

To order EarthLink Cable over Comcast lines, call 1-866-570-8333 and they will initiate the switch. The first step is to speak with the EL rep and check availability. They will then set you up with your first email address and then transfer you to Comcast so they can make the switch on their end. Comcast takes about 10-15 minutes to do their part and they will either call you back or you can stay on hold for the next step. They will send you to the online provisioning page to reprovision you with EarthLink as your ISP. Your domain will then switch from Comcast to EarthLink.

After you have switched, you can proceed to setup more email accounts from the EarthLink accounts page.

Can I use my existing cable modem equipment?

Yes, Any DOCSIS Cable Modem Should work with Earthlink Cable; Just be sure to contact your Cable Carrier with your HFC Cable Modem MAC Address which can be found in the back, side, or bottom of your modem.

What about Cable Amplifiers?

Signal boosters(Amplifiers) usually cause more noise on the line which will result in disconnects. Also it will kill the upstream signal (out of spec). Amps on a cable modem are never a good idea.

Bottom Line: Avoid any "booster" or "Amplifier" devices on your Cable Modem Line.

Do I need a firewall?

Yes! You are susceptible to attacks whenever you are connected. Fast connections make attacks on your system very efficient. An attacker can try many different attacks in a short amount of time. The always on nature of high speed Internet access with technologies like DSL or Cable modems make you a very convenient target.

What is a firewall?

A system designed to prevent unauthorized to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets


I am using a broadband router. Do I still need firewall software?

A firewall is still recommended, even if you use a broadband router. Most broadband routers provide a form of firewall protection from unwanted incoming traffic through the very mechanism it uses to share the internet connection. However, most do not contain a "traditional" firewall and do not block any outgoing traffic. This still makes you vulnerable to trojan or malicious "phone home" programs.

Can I get a free firewall?

Yes. There are several effective firewalls on the internet.

Recommended free firewalls:
Tiny Personal Firewall
Kerio Personal Firewall
