is it possible to hook up mulitple cable modems...?

Question

is it possible to hook up mulitpile cable modems or the same make,model and serial number to one computer to make the internet go faster. Yes I know i would have 3 internet bills but it would be worth it for the speed.

Answer 1

No, your network card is already enabled for 100MB connection; two network cards would only conflict, giving you to nic IP addresses; and won't really do much for you.

Answer 2

Yes and NO. Their are several routers, Linksys has one and Symantec use to make a security appliance that could take 2 connections. (outside of the commercial/service provider realm) Anyways, you can only use this for load balancing and redundancy, so, essentially, one line acts as a back-up if the other fails.

You can't actually make your speed twice as fast unless you somehow convince your provider to allow binding and then you would need to know some Cisco knowledge.

The reason the provider has to bind the lines also is due to the way TCP works, you don't know if the second line is the same distance or even goes into the same router, so when packets travel across a network that you try to run only binded on one side you end up with half the packets making it to the destination before the other half and well, your connection goes to all hell. (in the simplest terms).

Normally we do binding with any type of dedicated line, DS-1, DS-3, OC's and etc. Each line is the same distance and they both come into the same router at the ISP. It can also be done with DSL but you really gotta suck up to your provider and they need to be small.

Now, their is software and etc that claims to boost things, but it is all kind of a joke, just like web accelerators where they just downgraded the image quality instead of actually speeding up the connection (an example of "a joke").

So, you are pretty much SOL, with the way latency and TCP transmissions work, not going to happen. Well, lets not say NOT going to work, but you have to be DAMN good to do it... I mean, it would be expensive and you need to know your ****, but you could probably pull it off by running BGP and getting an ARIN handle so you can route yourself..... better to just buy up a wave from a wavelength service and get a connection into a local ISP and take 50 meg, might cost you $3k for the line and say $25-35 per meg for the bandwidth.

Answer 3

There are ways to pool 2 internet feeds into a common router. I do not believe there are devices that take more than 2 feeds.

You need a router with dual WAN ports. These are fairly costly and are commercial grade units. Often they need specific Network Interface Modules for this purpose and need be configured in detail. Usually the configuration is not done with a web GUI but with command line language and often you need a DB9 serial port link to it and use Hyperterminal to do the config work.

The router processor has to be fairly substantial to handle the load and this is part of the reason for the higher cost.

Now to correct the previous writer's comments. The LAN running at 100 Mbps is not the slow step. At best a cable modem will deliver 10 Mbps (usually 4 - 8 Mbps) download and less upload. This means that if you have a dual WAN router, its speed to the Internet is at best 20 Mbps, only 20% of the LAN speed. Clearly the previous writer did not think before he wrote.

Check Cisco and Adtran for products that will do what you want. Expect to pay in the $900 - $1800 range for the hardware.

Are you sure you really need this sort of speed? Can you afford it?

Answer 4

you will possibly could ask comcast as that's there kit, and there customary jobs end on the modem. I say it wont artwork, you will possibly could have yet another account in case you had to do it that way, some the place you've a splitter or router othewise you in easy terms have one computing device on line at a time, you in easy terms choose one modem and one router to run 4 computing device's of the only account, you need to use the router as a on the spot repeater if it to far to run ethernet cable.

Answer 5

D-Link has a router that does load-balancing. This is what you need. It has 2 WAN ports, 1 for each Modem. However, check with your cable company... You might not get any speed increase.. Maybe getting DSL for one and cable for the other is the way to go.

Answer 6

Your internet connection can only go as fast as the ISP allows, this is regulated their end. If you connect 2 modems, either your connection slows right down, or locks out. Some ISPs cut you off for this.

Answer 7

Just ask your isp for a faster internet speed for an increase price or switch to a isp that has faster speeds.
