Re: PPP control protocols

Who ever the ISP is that you are dialling cannot agree on the PPP protocols. In other words your ID to that network is wrong. It does not matter what OS you running. Go back to the ISP you must have one before you can connect. Depending on where you are and who that ISP is you will not and cannot connect until these protocols ie; ID and password have been established. If you have all of those and you thinks there is a problem go to them it sounds like your modem is fine.

Motorola Surfboard Cable Modem User Guide
The user guide for your Motorola Surfboard cable modem can mean the difference between knowing how to locate and diagnose problems with your connection or staring angrily into a maze of blinking lights.

The user guide provides information on properly setting up your cable modem, understanding the indicator lights and troubleshooting problems before you have to call your Internet Service Provider.Connecting Your Modem

Your Motorola Surfboard cable modem must be connected to your home's coaxial cable connection.
Connect the coaxial cable from your cable outlet into the "Input" jack on your cable modem.

If your modem is wireless, it will connect to any computers and wireless devices in your home through the wireless signal sent from the modem.

Wired Internet connections require that you use an Ethernet cable to connect your cable modem to any supported computers and devices.
Understanding the Front Panel

The front panel of your modem is your key to understanding the status of your cable modem.

The front panel features "Power," "Send," "Receive," "Online" and "Link" lights, each of which displays information about your modem.

The "Power" button will display a solid green light when operating normally and will turn off when there is a problem with the power supply.

The "Send" and "Receive" lights will transmit a solid green or blue color when data is being normally transmitted through your modem and will blink when it the modem is scanning for an upstream or downstream connection.

A solid green "Online" light indicates that you are connected to your Internet Service Provider, while no light indicates that the Internet connection in your home is experiencing problems.

A yellow "Link" light indicates that a computer is connected to your modem with an Ethernet connection while a blue light indicates that a high-speed Ethernet connection is being utilized through the modem.

Configuring TCP/IP

The Transmission Control Protocol/Internet Protocol provides the basic foundation for establishing a local network and a connection to the Internet. The TCP/IP can be configured in the "Control Panel" of your Windows computer. Open the "Network and Sharing Center" from the control panel and double-click the "Manage network connections" option. Right-click the network connection displayed and select "Properties," then select Internet Protocol Version 4 and open the TCP/IP properties menu. Select "Obtain an IP address automatically" and "Obtain DNS Server address automatically" from the TCP/IP properties menu and click "Ok" to save your TCP/IP settings.

Many technical issues with your cable modem can be resolved by power cycling your modem and the computers and devices connected to it.

To power cycle your modem, unplug it from the power supply for 10 to 15 seconds and reconnect it to the power supply.

Restart all of your connected computers and devices while your modem is power cycling. Problems with the "Send" and "Receive" functions can be the result of a poor signal being sent to your cable modem. Tighten the coaxial cable connection to your modem and contact your internet service provider if problems persist.

How do I configure my NIC with a static IP for use with a SpeedTouch Home?If you are using an Alcatel SpeedTouch Home (without a router), a PPPoE client such as NTS, WinPoet, or RASPPPoE, and are experiencing stalls and freezes while surfing or connected, it may be that your NIC is not configured correctly. You must set a Static IP on your NIC. If you have it incorrectly set for "Obtain IP automatically" it will be looking for a DHCP server that does not exist. During the time the NIC is searching for the DHCP server you will experience stalls and freezes. An incorrect NIC settings will also cause the PC to take a longer time to boot up.

HP USB Modem does not break dial tone

If the information connected to your post is all correct (56k V90 usb), and you are using one line for both the internet and the fax, you should hang up from the internet before you try to dial out the fax.

You have not indicated your PC model, so I don't know what operating system you are using. For XP and newer versions, you have to set up and configure the fax using the wizard or configuration software. If you have not done that yet, you need to.

In xp, go to start, Programs , Accessories , Communication , Fax , and then click Fax Console.

You said your computer is new. Win 7 and Vista are much the same:

1.Click the Start button , click All Programs, and then click Windows Fax and Scan.

2.At the bottom of the left pane, click Fax, and then click New Fax on the toolbar to launch the Fax Setup wizard.

3.Click Connect to a fax modem and follow the instructions.

You also need to make sure that your fax/modem is correctly listed in the control panel. In XP, start, control panel, printers and devices. If you do not have a fax printer listed, you need to "install a local fax printer."

The installation wizard should work in both OS without much trouble. If you do have difficulty, Microsoft and adobe both have "virtual printers" you can use. Look in Microsoft office or online.

Also check control panel of 7 to make sure that your modem and fax are listed correctly. Thanks for using Fixya.

  • Supports a wide range of DSLAM's for inter-operability
  • Complies to the T1.413 issue 2 standard (includes cable gauges like 24AWG (0.5mm) and 26AWG (0.4mm))

When you have modem plugged straight into computer, you can access it at, should ask for modem access code, (on bottom), then you can click 'advanced' > ppp location and set it for 'on computer'. There may also be a link for technician stats, it will give you info about isp connection. You should / might be able to browse but ISP may need original MAC address of machine (network adapter} you used when 1st signing up. Or if set to PPOE, it would look for name / PW in order to access INternet through ISP.
Anyway, try (after setting PPP on computer) Modem into WAN of router, access router, set PPOE > insert Log-in name / PW and save all settings. Then try homepage, if no, have router "clone MAC address" of the Network adapter you had the 5100 plugged into. Now it should work, even if no <INTERNET> light. ETHERNET light should be constant. Have router use DHCP to address machine independantly of what ISP addresses router, which it will do when modem (having connection confirmed with DSL light)

The other way, PPP location set 'on Modem', means the modem signs into ISP and then it assigns IP address with a timeout around 20 minutes. By getting connection test results when modem is connected to computer, it may seem to make sense, by understanding how ISP knows that modem access code / MAC address, and lets the settings of modem determine if router needs to sign in or not. If PPP is 'on modem', it will be looking for the MAC address of computer, that is why you may need to clone that address into router, so the router can appear as the machine to the modem, than the router assigns net address to computer.

Ditch the set up cd and do it manually! into the address bar on explorer. click login - pw is admin. then click set up then click ppp. enter your user name and password and click save. Take note of the result. All the other green lights mean the modem is synced, but not connecting which is usually user pw issue.
