2 cable modems one line? - Tilted Forum Project Discussion Community

Menoman · 12-20-2003, 12:48 AM

can you buy a second cable modem and hook it up on the same line as your first cable modem. Beacuse im tired of tring to get my router to work nicely

Ogre840 · 12-20-2003, 01:41 AM

I dont see why not, they would get a seperate IP address (instead of a sub IP) and it would slow your connection down just the same!

but their systems might not be able to comprehend two modems at one address...

Best bet, call your ISP

bryan2766 · 12-20-2003, 03:06 AM

Call your ISP and tell them you can't get your router to work and that you would like a second modem, hopefully they will send you a second one, bonus' of this are you get twice the download speed and one computer on the networking downloading a lot won't bog down the other one.

Smackre · 12-20-2003, 05:50 AM

well i called them and they said they would half to charge me double. I thought that was a little over kill. I figured i would just go out and buy my own modem. do you think its possable?

Pragma · 12-20-2003, 06:47 AM

The solution is to get your router working. If they give you two modems, you end up (as bryan said above) doubling your bandwidth/etc. - which is effectively the same as having two service agreements with them. So they charge for two.

If I were you, fix the router. It's much cheaper.

Yep.

Snakebyt · 12-20-2003, 12:03 PM

yea, fix the router...

merkerguitars · 12-20-2003, 02:15 PM

It might work to increase speed if you where able to get two modems with the exact same MAC address...then you could maybe steal some more bandwidth......

punx1325 · 12-20-2003, 05:57 PM

fix the router, they will charge you double the price,

Smackre · 12-20-2003, 08:18 PM

well fiddled around with my router and got it working. I was tring to hook the modem strait to the router and it was slowing me down a ton. I now got the modem hooked up 2 one comp usb. and the router hooked between the comps with the ethernet cards. nice and fast now.

Smackre · 12-20-2003, 08:29 PM

well had it working. then i restart my second computer. the one not connected to the cable modem and it dies on me. Some reason i can never get this network stuff to stay up for a long time.

The_Dude · 12-20-2003, 08:38 PM

my isp said that they had to register the mac address of each router, so you cant just add a new router in. i was wonderin about the same thing.

smackre, dont power off your modem or your router. if you add switch the modem between lets say a pc and then the router, u will have to restart the modem (power off, then back on)

tritium · 12-20-2003, 09:37 PM

There are number of factors at work here. We can assist you, Smackre, but you'll have to provide more information. For example, what type of router are you using (make, model, wireless, etc.). Who is your service provider? What kind of cables are you using to string up your network? Can the two PCs "see" one another over the network when it DOES function? Are you PCs set for DHCP or static IP? Is your router setup for DHCP for itself and your network? Does your provider allow for static IP, if that's what you are using? Have you tried resetting the router? Are you using a firewall on one or either of your computers (software or hardware)?

tritium · 12-20-2003, 09:41 PM

Sometimes you need to have the uplink enabled on the router too. Maybe that's it? The_Dude posts a good point. I have heard of service providers recording a router's MAC address and allowing only that router to function on the network. I'm on Comcast and we didn't have that problem when I recently switched out a router -- Cox Cable is safe too.

Have you tried a switch or a hub in place of the router? Tried to spoof the MAC with your router?

blizzak · 12-20-2003, 10:52 PM

if you're using a cable modem, you'll have to release the ip from whatever computer the cable modem used to use before you plug it into the router
this woulc be accomplished by doing "ipconfig /release" in dos or in the run bar or wherever on that computer
also, do ipconfig /all in dos and you'll see some interesting stuff too
then you have to set the router to automatically get an ip from the cable modem, and it should pretty much just work after a while...heh
I have dsl myself, but I know my friends cable modem is always hard to configure with the router, so good luck

Smackre · 12-21-2003, 12:35 AM

im using a motorola 4101 cable modem. A Belkin 4 port router. I cant find a part# for it. Im hooking the cable modem up to PC1 via usb. then im hooking port1 of routert to ethenet of PC1. And port2 of router to ethernet of pc2. I can get the net up one pc1 great. And had net up on pc2 a few times but soon as i restart on pc2 i loss it....im on adelphia power link cable internet..im using all cat5 cables and the one usb for the modem...both computers are in same room so they can see them selfs...

you said sumtin about having a uplink. what do u mean?

if anyone can think of any more info i need lemme know

Pragma · 12-21-2003, 08:13 AM

There should be one port on the router labelled "uplink" - this is what you should plug the cable modem into (cable modem should also have a ethernet port, instead of just USB) - run a cat5 patch cable from the cable modem to the uplink port of the router.

Then run two cat5 cables from other ports on the router (ie: ports 2 and 3) to your two computers.

That should work, after you configure everything properly.

Smackre · 12-21-2003, 12:09 PM

i had it hooked up like that for a long time. but it was always realy realy slow. with out router i can get webpages in 1-2 secs. with router hooked up like that it takes 10-15 seconds for pages to load. But if it hook it to one computer usb and then to other threw the first coputer it works fast again.

sailor · 12-21-2003, 12:29 PM

Sounds like some setting in your router. Connecting a router shouldnt have any effect on speed. What about download speed? Does it change?

Smackre · 12-21-2003, 12:32 PM

no dl speed is still fast...

when i have it hooked up 2 one comp via usb and then to the next threw the router and its working ive noticed on "my network connections it adds a "intetnet gateway" but soon as i restart my comp that goes again. anyknow why or a way to get it back?

Smackre · 12-21-2003, 05:30 PM

i got thinking. Do you guys think a hub would fix the problem. Cuz like you gus said routers are supose to have a uplink. and in this situation it dont. Lemme know what u guys think.

tritium · 12-21-2003, 08:54 PM

Hubs are great and all, but they provide absolutely no protection from sources attempting to access your computer from across the internet. You can try a hub, but if you're willing to make a purchase, get another router.

If it doesn't work, then you can take it back in favor of a hub at the same store.

In fact, you might need neither. Since your cable modem works over USB, you could connect the two computers via a cross-over cable (available in lengths like those that you were describing). Then you could connect both network cards of the two PCs directly with the cross-over cable and enable internet connection sharing on the computer with the cable modem. Then you could eliminate the router/hub entirely...

VeXteR · 12-21-2003, 08:55 PM

You really need to turn the router upside down and read the stuff on the bottom. Or go to Belkins website and compare pictures. We also need to know what OS you are running on the 2 PCs.

Your problem is you havnt properly set up your network.

And for your question, NO you cant just go get a cable modem, plug it in and steal interent. Each modem has unique number called a Mac address. The cable company only allows KNOWN mac address on the internet...

If you did do this you would have to pay double.

And last but not least, their is a web site called www.google.com Type in what you want to know about and it will give you about eleventy billion responses... Their is a catch though, you have to read.... HEHEH Just giving the noob a hardtime.

Seriously, get that info back in here and we can help you to do this the right way....

steveincolumbus · 12-21-2003, 09:52 PM

well it loading pages slow but still fast downloads sounds like a DNS problems, its takeing time to resolve hostnames...... it should have a dns server in the router...
switch to static ip's on the 2 pc's
use the isp's dns
defalt gateway is the intemnal adress of the router
subnet mask of 255.255.255.0

Smackre · 12-26-2003, 09:04 AM

bought a hub and it worked like a charm. I problem was my router wanted a uplink and my cable modem could not output on both ethernet and usb. thanks you.
