Cable Modem Troubleshooting: Scientific Atlanta DPC2100

HOW DO I CONNECT TO THE INTERNET USING USB

Is there a way to complete turn off power to the modem? I unplugged the power source and there are lights still blinking at a 10 second interval.

I’d appreciate if somebody could answer this question. I have an atlanta modem and it seems to work fine but the PC light is either flicking all the time while it’s connect or the PC light is not on at all. What does this mean? Is there a connection issue?

Cheers.

hey i have this same modem thing and i plugged it into my usb and it WAS working and i had to re install the computer and when i updated everything and plugged it in it keeps saying unknown device. it wont let me install any drivers for it except a driver called “unknown device” can someone help me out with this?

I agree but between the router and the modem …try to set it up yourself.. and you’ll go through alot of pain I ripped my router out and just said the heck with it

@redh brown:

Sorry I honestly don’t even know what a 36 console is. Do you mean a 36″ console TV? Since you don’t have a router, I’m guessing you’re plugging the modem directly into your Xbox? Which leads to me these two questions:

1. Has the modem ever worked while hooked up to a PC?
2. Who is your ISP? Some of them will lock a modem to only work with a specific MAC address, and since your modem was (or may have been?) plugged into a PC, now you need to get the ISP to “allow” the Xbox’s MAC address.

Hope this helps -

I have a Virgin Media cable connection and I’m having problems setting my Scientific Atlanta 2100 (the modem Virgin gave me) up with my wireless router – a Belkin G + MIMO. I can get 2 networked PCs online but i cannot get my laptop or other devices linked wirelessly. It used to work (although intermitantly) but since unplugging for another reason, the wireless aspect has not worked again since. Please help!

Iam having a Scientific Atlanta 2100 cable modem supplied by Virgin Media. Can I connect one PC via Ehernet portal and another via USB portal at the same time.

If you unplug all the cables the light will stop, its blinking either from the ethernet cord from your computer or from the coaxle cable. Either way you arn’t paying for that little light if thats what you cared about because the power is comming from one of the two cords.

algien que me pueda decir porque mi pc me dice que tengo conectividad limitada o ninguna. y cuando enciendo el utorrent se reinicia solo y no encuentro la solucion.

I have got this modem through virgin media broadband.

I have an orange/wanadoo livebox from my previous ISP that i wanted to use to give me “wireless”.

Is it possible to connect the VM modem to the livebox to give me wireless? The livebox connects to the net through telephone line RJ11 connector.

Hola, tengo un problema con los puertos del emule y quizá aquí encuentre la solución… tengo la id baja y me han dicho que es cosa del modem ¿podeis ayudarme? gracias

I currently have this modem and I can tell you all mostly what you need to know. First this is a simple good design for this modem but the quality of completly crap. I do have to unplug it atleast 2 or 3 times a day in order to restart it to get a proper internet connection because it gets too hot too easily, especially if you are a gamer. If you don’t have the installation cd it is virtually impossible to locate the drivers for the usb connection so if you cannot use it through ethernet port then you may as well return it. The modem is obsolete so they do not manufacture this model anymore so they do not provide support for it and it sucks.

Eu gostaria que alguém me passace o link para mim baixar o soft do driver cable modem DPC2100 !!!!

I recently got the dcp2100. I have a netgear wireless router and can not hook it up. I am hooked up to the computer thru the usb port but can not get it going with my ehternet hub. I don’t know what else to do help.

Hi, i have this modem, and im just wondering if i can unplug the ethernet cord from my airport (which is connected to my modem by ethernet), and plug it directly into my computer so my internet is faster? it is simple but i just want to know if this will make any problems. is it completely safe?

Hello,

I have a Scientific Atlanta DPC2100 modem. I just recently got cable internet thru brighthouse, and was provided with a modem just like the one that i have and it is working. but, when I want to hook mine up in a different room all of the lights on the modem flash together about every second. how can I fix this so that I can use this modem?

I have this modem and it is a piece of shit… I have it setup with a belkin wireless router and I have to unplug everything from it inclusing the coax and ethernet cables 10 times a day and wait for 2 minutes to get it working again when it drops the connection. There seems to be a resynchronization problem whenever the modem experiences a little disturbance. It works fine on USB but with a router it completely blows.

Actually this turned out to be a terrific little performer.
It was my ISP’s fault that games didn’t work since they were disabling a lot of protocols, and it’s really delivering now.

I’m joining the club that Cable is best for gaming and am fully impressed with this product. Only a power switch would be an improvement imho

ola tengo un wireles usb adaptater que es netgear WG111v2 y lo quiero instalar pero no puedo por que no tengo el disco de instalacion que puedo acer para instalarlo sin el disco eske cuando lo conectome pone que tengo que instalar el software controlador y que introduzca el disco pero yo no tengo el disco que puedo acer para instalarlo sin el disco

hi i need help finding the network password for this router so i can set up the internet on my ipod touch.
any solutions???????????

I have the 2100 router through comcast cable and it i s soooooo slow almost like dial up. I am connected with the ethernet cord, should i plug in the usb, will it help or is it the modem? The send and recieve lights are hardly ever on, what does that mean? I really would appreciate it if someone could help me figure out why my connection is so slow. I thought cable was supposed to be faster? Any thoughts????????

I have this dpc 2100 cable modem but i need to connect it to my pc by usb but the problem is i got win xp 64 and i cant find any driver for it on oficial webpage doenst seems to be some kind of driver for win 64 plz let me know if theres any option or any driver avaiblable. thanx

I got this modem from my ISP, and I’m having problems maintaining a connection. I have been told by the cable company that the reason I disconnect so much is because I have to run my cable off a 3-way splitter (one to the modem, the other two go to tvs), however, I’ve noticed that the internet cuts out ever 2-3 minutes for about one minute, over the course of several hours, mostly during the early afternoon and late morning. If the splitter were the cause, wouldn’t I cut out ALL the time?

Note: Using my browser, it doesn’t cut out so much. When I play games online (World of Warcraft, Total War, etc..) its very regular.

Please, any information would be greatly appreciated.

Hi, I noticed the comment from a few others about local IP address of the Cisco/Scientific Atlanta Cable Modem Modl RPC 2100. This local IP is useful to access the “admin page” of a modem from a PC on the same internal network.
Soemone (Jimmy) said that the local IP was 192.168.100.1 (the same as the Motorla cable modem.
However that address (http://192.168.100.1) dpes not bring up any web-page interface. I can PING that address 192.168.100.1 from the router which I have connected to the cable modem.
Jimmy correctled that web-page address , to be:-
http://192.160.100.1/_aslvl.asp
But thgis does not work either, and ai cannot PING 192.160.100.1 from it attached router.
Any ideas how to access the admin web-page of this cable modem?
Thanks,
Stan

Hey,

I have previously installed the driver, as I’m using it in my second computer with a USB cable, and it all worked fine. Suddenly today, I get a message saying that Windows (Vista) doesn’t recognize the USB device. The modem is shown in the list of devices as ‘Unknown Device’. I re-downloaded the drivers from the official site and tried to update that ‘Unknown Device’, it responded saying the device already has the most up-to-date drivers. I tried uninstalling it and installing it (even after rebooting), to no avail. I’m using Windows Vista (Home version) in a HP 6730s laptop. What can possibly be the problem?

Thanks for your time,
Bardhyl

Re response by Ross McKillop 05.03.08 at 9:19 am to Zak…

The following is directly from the mfr’s (DPC 2100 and EPC 2100) Cable Modem User’s Guide:

“Connect your PC to either the ETHERNET port or the USB port using the
appropriate data cable. Do not connect your PC to both the Ethernet and
USB ports at the same time. You can connect two separate PCs to the
gateway cable modem at the same time by connecting one PC to the
Ethernet port and one PC to the USB port.”

Por favor si alguien sabe como entrar a la configuracion del modem, que me pase como debo entrar ya he probado con varias IP en el explorer, 192.168.0.1 192.168.1.100 no funcionan tampoco con la que me da la salida de ipconfig como puerta de enlace o como dhcp, ya nose como entrar para ver si hay algunos puertos bloqueados para jugar al pes2009. Desde ya Muchas Gracias

FOR THOSE WHO HAV ISSUES WITH XBOX 360 LIVE CONECTION…
my solution… if your ISP can give you another model (motorola would be an excelent choice…) it will be the one and only solution to this problem… this webstar model does not support MTU configuration and most of the ISP would not changue that number in their configurations… sorry but that was my one and only solution after 2 months of TECHNICAL SUPPORT VISITS of my ISP… a shame i supouse…
