SOURCE: RCA DCM425 modem ethernet connection won't work

In short, you have to either

  1. renew your ip on Computer 1, or
  2. hard-reboot your cable modem and then reboot or renew your ip on Computer 1.
Details below.

The modem is communicating with the servers at your ISP (Internet Service Provider) to give your computers an IP address. The ISP may have your modem set up to be issued only one IP address. Thus using both USB and Ethernet could be restricted by your ISP.

The IP address is most likely a dynamic IP that expires after a few days or weeks, unless you bought a business account that has a static IP (which is used for hosting permanent websites).

When a computer is not communicating with a Cable Modem or you shift between the connections on the modem, it may be necessary to re-establish configurations. The following can be steps to reset all components to re-establish configurations:
  1. Do a hard-reset on the modem. On the back of the modem is a reset pinhole. If you press the button quickly, this can soft-reset the modem, just restarting the modem. If you press the button and hold it for more than 10 seconds, this can hard-reset the modem, thus resetting and re-establishing configuration with the ISP servers.
  2. Restart the computer or at the command prompt (Start | Run | Cmd | Enter) issue two commands ... "ipconfig /release" and then "ipconfig /renew". This will release your IP and request a new one from your ISP.
These steps are required when adjustments occur especially when shifting between connections on the back of the modem.

SOURCE: 2wire modem not broadcasting wireless signal

Hey I was given a high speed Bell Sympatico interent system and I even had 7 different modems installed in one year and even including 2 new 2wire modems..

Firstly all of the problems were firstly related to the fact there was no Bell high speed cable actually in my area, even though i had paid for a high speed interent service for years too.

and the problmes were next directly also to the mostly pretentious, incompetent Bell technicians.

Do first use an interent speed test site to verify your actual supplied interent speeds and do always tell the ISP that you want real high speeds and real service from them rightfully ..

FINALLY THEY BELL SYMPATICO WOULD CORRECT THEIR SYSTEM PROBLEMS , AND FINALLY GAVE ME EVEN A FIBER OPTIC CABLE CONNECTION TOO, AND IT WOULD RUN GOOD FOR 3 WEEKS next till another fool, a Bell technican make some other LINE changes and my system became slow, problemed,

THUS SO MANY TIMES now I had discovered firsthand what the right hand of BELL,ca giveth the left hand can take away.. for it seems everytime they the techs do make new line changes my own ISP address next would change AS A RESULT too and lead to some of the new problems...

So I again called Bell tech and they next tend to do a ping and do something else and so for another short period their interent system would work till... the other hand had taken it away..

Continue to give them the techs hell for they deserve it and tend not to tell the truth as to what the real problems are.

If you have a 2 wire modem you do not need firewall software too and you can turn it off.

SOURCE: Dynamode Internal Fax Modem 56K

i had same problem trying to receive faxes until i changed phone connections.

according to a motorola manual (link below) this has something to do with being connected to a "proper analog phone line".

i had the phone line running from wall to a newer gateway (maybe 8 months) dec 07 to a maybe 2 year old compaq. kept getting that loop current error on the compaq when trying to receive a fax until i elimated the gateway connection and plugged the wall right into the compaq.

here's a link that might help:

see section 6, troubleshooting. hope this helps...

SOURCE: ethernet vs. usb

FYI for those people trying to use a ethernet and usb cable from a cable modem - it may work for a while but it won't work forever - your ISP will only allow one IP address out of the modem unless you pay for additional addresses (then you need a switch). Each device you have on the modem is fighting for that IP and eventually it will just quit working (if it works at all).

If you want more than one computer on your network (on the Internet or sharing printers/files, etc) then you need a router or a gateway (cable modem/router combo which I DON'T recommend).

How to connect my sagem to the computer and check if it is working correctly thank you

follow these steps : 1. Power off your computer. Connect the modem to the signal source. If the source is a cable signal, connect the modem with a cable wire. If it's a DSL signal, connect it with a telephone wire.
2. Connect the proper ends of the USB wire to the USB ports on the modem and the computer.
3. Connect the ethernet cable to the modem and the computer.
4. Insert the power source into the modem and then plug it into the wall socket or the series circuit.
5. Wait until all the lights on the modem are lit and then turn on the computer. When the Hardware Wizard detects the new device, you may have to insert the disk that came with it to install the software for the device. This will complete the connection of the modem to the computer.

Can this be used as a 56k router? I need to have a temporary internet connection and it is only a basic connection because of the type of phone there is at the house. We tried to connect but I don't have...

The SB4100 is a digital modem that uses cable TV network to provide broadband Internet access, it can't work with an analog telephone line, for this type of Internet access (also called switched Internet connection), you need an analog internal or external 56K modem, and also you'll need a user name and password (an account) from the Internet provider service (ISP) ; for a temporary Internet connection maybe a prepaid cellular modem (GPRS, EDGE, 3G or 4G) USB type could help you better.

What is error code 651?

I have fixed mind through following steps, OS Windows 7. This works if you can still use cable internet, so that system can download the driver.

In my case there was no wifi utility, no connections detecting, no bars IIII.


Please note it is mostly to do with your network drivers, if you go to device manager under the network adapters, you will see network controller marked in yellow. Dont worry.

To make your wifi connection work please complete the following steps:


Device manager > trouble shooting ( column 3 , second last row )

Now under " Hardware and Sounds" heading go to configure a device.

It will start trouble shooting automatically, and try to download and install the right network control driver.

My system is using: Realtek PCIe FE Family Controller and after downloading the driver. I have now following installed.

Realtek RTL8191 SE802.11 b/g/n Wifi Adapter ( this was missing )

Now when I go back to device manager I have both are functioning and after reboot I automatically connect to the wifi. So everything is fine.

So my advice to all whatever make is your PC / OS , do go to device manager and try trouble shooting.

For those who have found this solution helpful, please email me:

My usb modem [lemon 3g] does not get detected. when i plug the modem it does not show anything i.e usb icon detected hardware etc. when i clikc on cmy computer also it does not show any connection why is...

First, check for the power source, there should be a light indicator on the panel of the modem, else, power is a problem, check your adapter/power cable. Next, is use USB cable/USB port, try to use other USB cable/USB port. Another option is to check your Control Panel - Device Manager, see if there is a USB Modem currently installed. Remove/delete the device from your Device Manager. Going back to Control Panel, select Add Hardware. If still fails to detect, your Modem is dead.
Good luck.

there are few options to test
Option 1) Check if the SSID and WEP key in the modem page
tally with your logon SSID or WEP key, because
limited connectivity issue happens when SSID and
WEP does not match
Option 2) Restart your modem
Option 3) Check wirings on telephone line , replace tephone line
with another telephone line and make sure the socket
plugged in from the telephone line is a BB tel number
and service has been paid promptly every month
Option 4) Change the wireless channel in the modem page to
detect the wireless device from 9-11 at
address in Internet explorer
Option 5) Bring laptop closer to the modem and ensure wireless
led on the modem is lighted and the wireless led from
the Laptop is enabled

Trying to launch internet gives me error 680.

680 - There is no dial tone.

All versions of Windows are affected by this error.
No dial tone: There are many possible causes of a No Dial Tone Error.
First, try testing the modem's ability to detect dial tone and to dial by using HyperTerminal with the direct to COM port connect method - see Using HyperTerminal. If you give your modem an AT&FX1 command, and then a dial command, dial-tone detection will be disabled; if you still do not get dial tone, the modem may not be installed correctly (especially if it is a PCI or soft-modem); or the cable from the modem to the phone-line jack may be bad or installed in the wrong connector on the modem - try another line cord, and make sure you are plugged in to the LINE - not phone - jack on the modem. Plug a regular phone into the phone jack on the modem and make sure it has dial tone. The modem may also be defective. Many new modems come with an electronic circuit instead of the traditional electro-mechanical relay used to take the modem off-hook. Some of these designs are proving less reliable; often, they will be 'stuck' in the off-hook position, so unplugging, the plugging in the phone cord may give dial-tone. If this is the case, the modem needs repair or replacement.
If the modem will blind dial (x1), but not detect dial-tone otherwise, the problem is likely to be in the proper selection of the Country in Windows->ControlPanel->Telephony or in improper installation of the modem or lack of support for your country in the driver you are using. Check to see if there are updated drivers for your modem.
If the modem dials properly with detection (x3) in HyperTerminal, but does not detect dial tone when using DUNs, the problem may be DUNs (check for upgrade or re-install) or the proper setup and modem selection for the DUNs connectoid.
For Embarq telephone service customers, this error can indicate that you have a message waiting in your voicemail. Embarq changes the dial-tone sound to a "fast" busy signal when a new message is present in your voicemail box. This "fast" busy signal can confuse the modem into thinking there is no-dial tone present on the line.

Yes! the error could be the pcmcia modem card.

A PCMCIA Card is used to connect to your laptop different components that you it doesn't have.
More information about PCMCIA
For most ISPs all you need to connect to the Internet is a network card. Check if your laptop has an integrated network card. Then contact your ISP and ask him if you need something else except a network card to connect to Internet.
