HOW DO I CONNECT TO THE INTERNET USING USB
Eric,
If this is your modem (the Scientific Atlanta DPC2100) you should be able to plug this modem, using the USB c able, directly into your PC. If you’re using Windows, it should prompt you to install the modem – use the CD that came with this modem.
USB connections can be a bit ‘flakey’ at times – if you’re currently using this modem via an ethernet cable, and it works, you may just want to leave it as it is (if it’s not broken, don’t fix it
)
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.
Hi there, I have a Atlanata DPC2100 connecting a cable broadband internet service via ethernet cable to my computer.
I want to set up a wireless network.
does that mean that the 2100 becomes obsolete or do i connect something else to the 2100 to achieve this.
this information is completely lacking in the 2100 guide and instructions. thanks.
For a computer idiot this question should be answered in youe advice, dont you think, because its the first thing that someone wants to do after their internet provider has fobbed them off with a non-wireless set-up!!!!
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.
I have recently installed this type of cable modem. I have Cox supplied internet. I can not always get on the internet without having to unplug the power cord or cable. It tells me I have limited or no connectivity. What could possible be the problem?
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?
iam haveing trouble in

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
hi there?!
i have a 36 console and i’m trying to connect it on xbox live, but when i try test the connection it keeps on saying that my MTU is failed? i dont know why my MTU keeps on failing because i’m using a modem not a router, can you help me with this?
by the way my modem is scientific atlanta dpc 2100
@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 -
Ross
ok, so you mean when MTU is failed i need to call my ISP to allow the mac address of my xbox 360 console?
my ISP is cox cable
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!
what is the ip address to configure this modem?
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.
@Zak:
Sadly no, it’s one or the other. What you need is a router, so you can connect multiple devices to the same Internet connection. The good news is they’re fairly inexpensive now.
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.
Hey guys im having trouble trying to hook up my xbox live, this modem only has 1 Ehernet portal does the xbox ehernet cabel and the ehernet cabel for the computer have to be plugged it to

Hey there I recently got this modem from my cable isp and it got setup without a hitch.
Problem is my Blizzard games can’t connect to the gaming server. I’ve been wondering for some time now whether I have to (or if it’s possible) setup port forwarding on this model so the games work? Maybe I need to flash it, is this possible at all?
Or it might just be my isp’s fault, I’ve already contacted them locally here in Mozambique. Any clues most welcome.
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.
Hey why does my send and recieve lights keep on dropping? It causes me to lose internet connection… Any ideas? Thanks
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.
figured it out.
goto router setup (usually 192.168.0.1) and for MAC address choose use computer address. Cox is looking for my PC’s MAC address and purposely trying to block the router.

Hi,
I am trying to setup a wireless router network. my service provider supplied a cable modem which i am trying to configure with linksys wireless router. when i run the linsys router setup CD it is not identifying my DSL cable.
probably this is with the kind of cable I am using. someone has suggested cross cable. is that a workable solution?
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 Scientific-Atlanta WebSTAR Cable Modem and
it works fine while connected via an ethernet cable.
It works also via the usb connection. The problem starts after sleep/wakeup of the laptop. Sometimes after wakeup the connection is there, sometimes not. Restarting the PC solves the problem, but restarting vista takes ages. It is a big bore. Does somebody have a solution?
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.
Здравствуйте. Как долезть на ЕРС2100R2 до сервисного или инженерного меню, есть ли в нем возможность изменить IP DHCP
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
Gostaria de saber com posso configurar (rotear) meu scientific Atlanta 2100. Minha internet é de 1M, e possuo um switch des-1008D para receber o modem.
