How to combine 2 or more DSL modems for more bandwidth

[vankusanagi]

Can you somehow connect two or more different DSL lines or modems into one hub, router, or whatever to increase the bandwidth? Or have some sort of advantage?

I have heard of this being done before! From my teacher in my computer engineering classes. So I know it is possible. I just don't know how to do it.

What would bridging two modems together and sharing that bridge with the network do? But I really would like to combine at lease 3 DSLs together. Cause of the number of computers, DVRs, game systems, and other wireless devices in this house is insane and we max it out easily. Just 3 out of 20 of those things can really slow down my internet!!!

My DSL provider will not allow an upgrade and we are planning on adding extra lines anyway so we can let each person have their own line. But this is a waste of bandwidth and money!!! Cause when I go to download some movies to my DVR and play my xbox the xbox (video game system) has a bad connection with everyone... Thats just two things. Someone gets on their xbox or download some stuff and I get kicked offline all the time...

Anyway, I have taken plenty of computer classes and can do anything with enough instruction. So if it requires building or modding a router or something then I can do it. Ideally I'd like to get 4 DSL lines and then output it to my network. We plan to get 5 DSL lines installed in 5 rooms with 5 new phone numbers to go along with it cause they won't let us just not have a phone for some reason... Now one line will be left alone for my parents office. But the other 4 lines I would love to combine!

Just to give you an idea of how much of a waste of money this is, it is $85 per line! Thats $425 a month!!!! So my parents are insane. But have the money... I still say it's a waste of money cause I'll max out my own and then my sisters won't even use theirs... I have the house wired up and most things are also wireless to. So It'll be no problem to get them all on the same network! Sense we already are. All I need to do is hook all the DSL modems up in one room and combine them.

Can someone please help me? I really hate to waste money... Oh and by the way we have no other ISPs at all... And never will we live in the mountains in the middle of nowhere. And no satellite is obviously not an option...

Thanks

From what i know this is not possible. Other wise i would have done it myself.

You cant. End of post.
Thats because, the phone line coming in your house is only carrying 1 MBPS data. If it were possible, the bandwidth would divide into two, both giving 512 KBPS each. But I dont think that its possible.

Not possible!

I Think its Possible dont know about this properly but the method is called BRIDGING two connection
You Might have seen this option on the LAN CONNECTIONS as well u need to SELECT both LAN 1 and LAN 2 and Right click on it Select bridge

It will bridge both connections but i am not sure about it do some google on that one

Totally possible, but its not like just connecting 2 modems to your PC & you're done, you have to connect 1 Router as mid point of DSL Modems.. NexLand ISB Pro800 Turbo router would do it..

Intergrate Inspect from Vicomsoft can do it, download the trial from http://www.vicomsoft.com/products/filter/index.html and follow the instruction,

P.S: I haven't done it myself yet, but i am going to do it soon as my CCNA project.

i think it can be done through Load Balancer switch, to combine all bandwidth.

Um? End of post? Lol, what made you so smart to say thats that? You have stock in the DSL companies? Anyway, whats up with the 1 Mbps thing? Is that all you get on your line? Cause I get 2.5 Mbps... I don't know anyone how doesn't at least get 1.5...

You guys have very limited imaginations, it seems. First of all didn't I say I already know this is possible? Why would I say that if I didn't know for a fact that it is? Secondly you can actually hack your ISP to up your bandwidth and a lot of other crap. Also by doing so you can send a request and get response else where. Though this is illegal and shouldn't be attempted... But technically that would give you the ability to use two Modems or more.

Now for the legal part. Ever heard of load balancing using a Dual Wan Router??? You take two DSL lines and the router will sort everything out just fine. So basically you get twice the bandwidth. But I wanted to combine 4 lines no just two. And I've never heard of one doing 4... Check it out if you need to... : http://www.ezlan.net/loadbalance.html or http://www.amazon.com/Cisco-RV042-D...3?ie=UTF8&s=electronics&qid=1269432310&sr=1-3

So lets open our minds before thinking you know everything first. ok?

It is possible. OMG isn't that amazing? Try to be helpful. At least tell us why you think it isn't possible. And what makes you capable of determining that it isn't possible. Read the rest of the posts please.

Ok, that is a load balancing router but it says it will only use the second modem if the first goes down... This wouldn't be helpful unless running a server... This isn't how I thought a load balanced router worked. I thought it would lets say use one modem for on port, address, something and then use the other so that it can't be over loaded... right? Something like that right?

Anyway, does anyone know of one that supports up to 4 modems or at least 3? I need to send out a one DSL source to 4 areas of WiFi and the more the better. Cause at any point in time I could have 20 devices on it ranging from mp3 players, video game systems and computers. At the moment we over load the one line easily... So we are going to get up to 5 more lines. But this makes makes means so WiFi areas will get over used and some underused...

I don't have any option to change providers or upgrade my bandwidth.... :/

it is possible, people in the uk do this with hacked cable modems and also with legal ones...just search on wiredpakistan you'll find a thread with a link towards doing this and it was done by a pakistani!

 

[mobeeen]

let me clear u first thing this scenario is not possible yet example u have 2 connections first is 1mb second is 2mb 1mb average downloading speed is 100kpbs and secnd 2mb 200kpbs and u are trying to combine both connections and download a file average speed of 300kpbs .this is not possible reason becoz u have 2 modems and each modem have own unique ip; ip is your identity on internet all communication on internet is base on IP ISP give u Ip on modem now u have 2 identity's u cant communicate on internet with 2 ips at a time .

lets talk abt possible solution combine 2 modems for internally users each user use one connection for send and receive data this can be done by dual wan modem or linux based machine and new windows 2008 with forefront(ISA) they receive users data and auto select one modem for send your data this is called load balancing your users divide your bandwidth divide u are watching youtube and your bro start downloadin they use one modem bandwidth and u use one modem bandwidth another feature is fault Torrance if one connection goes down all users use second connection automatically or manually its upon your setup no down time this is IT word Called Fault Torrance .

 

[vankusanagi]

u can do load balancing and fault Torrance thru linux and winodws but this is manageable for u other solution is buy business class dual wan dsl modem u cant merge 2 or more connections becoz 2 or more connections means 2 or more public ips and on internet u can use only one public ip for sending and receiving data !!

Could you dumb that down a bit? and up a bit to... "becoz" its confusing... What is IPS? And if fault torrance is what i think it is then it has nothing to do with what I need here..... :/ Ok I really have no idea what you are really trying to say... Sorry... You say we can do something in the beginning then you say we need something but then you say we can't do something??? You do realize lives just may depend on your clarity?

 

[alikhan]

There are load balancing devices by TP-Link. OR, use WinGate. Tut = http://www.asadahmad.com/tutorials/tut_multiple_connections.htm

 

[Spooge]

this is very interesting, Do let us know how it goes...

Yeah i just confirmed it, You will be routed to second modem only if first one goes down, Did you try the software i referred? Please try and post the results..

 

[kenfatality]

It is possible..for sure..

 

[koolest]

ya its possible bro..

 

[CrashBandicoot]

Unless you are a hobbyist nerd,the amount of money and trouble you will spend in buying modems and switches as told by members in this thread,instead get yourself a faster connection?

 

[shujaswati]

Its not possible...as both lines are different bandwidths....Both goth different IPs ... so can't work as one...

But u can buy a ADSL router cable of getting 2 WAN connections and allowing u to use bot connection simultaneously but separately.... i.e. When one line is one full BW other line starts to get work.

I Think He Is Right.

well i did it my self but not possible on win xp . u need cisco router that combine 2 or even or dsl connection . and through isa server the data routed . thats all but you have to spend 20k for router so expensive . in my frinds company they are using 4 ptcl connection of 4 mbps through cisco router .
