Combine or bond 2 ADSL

[oztek]

Hey guys
I've got 2 adsl connections on 2 phone lines.

Is there anyway that I can combine the 2 together to increase the speed? They are with 2 different ISPs one is unlimited and the other one gives me 50gb (naked dsl)

2 x ADSL2 = ADSL4 ?

In a word no. Each phone line has limitations speed wise, you cant build a super fast one out of 2.

As mentioned.... no.

You could also cause interference and possibly even damage to telephone systems by shorting the lines together and you'd be liable for any damage or even just for interfering with cabling, connections and networks.

Some routers will let you bond links, bu these are more the higher end kit.
And the links would need to be from the same ISP, because at there end they need to setup a bonded interface.

These sorts of setups were common where you could only get 2Mb E1 connections etc. The Telecoms company would bond several together to give E1 x n. And your router would have multiple connections matching the 'bond'.

Sort of like Teaming interfaces on Windows.

But on ADSL from 2 different ISPs?

No.

i currently get around 2mb from each line so combining them together should increase it to 4mb not ADSL4

I know there are some gears out there designed to do that and I dont think it will damage anything i know wer doing it in the office with a high end cisco machine.

So if the 2 dsl connections are with the same company i can get some router to do it? would you have a rough idea on costs etc..?

[autotuner]

You'd have to ask the ISP if they supported it for starters. And if so what hardware they recommend, like with most things, there are usually incompatabilities with different vendors.

As to costs...don't know. I was only ever buying the high end Cisco kit. The purchase orders usually had quite a few zeros......

Combining connections is more of an ISDN method than ADSL.

I'd be fairly certain that if you cannot access ADSL2/2+ at your location, any other technology would also be restricted.

Check with your ISP/s.

if you have a spare pc laying around you can install clearos or smoothwall, then put both adsl modems into seperate network cards and set it up to use both connections.

[autotuner]

Still doesn't really combine them.
Yes you can direct traffic, but you can do this with simple policy based routing anyway.

Reminds me of back in the day of dialup people combining 2x 56kbps for a blistering 112kbps!

You won't get speed increase to 4mb/s by combining two lines. You can balance the load which will give you ability to have more computers to download at speed upto 2mb/s. Your "combined" speed still will be 2mb/s but the pipe will be bigger. Your ISP should support it as well, so you need to check that with them.

We have this setup at work using a dratek 2820 modem.
it has a lot of different options on how you want to use the lines, ie share load or second line as fall back.
good options are if you have all torrents going to one line and keep other for browsing or you can have certain users default to different lines.

one problem i found was that when logged into a secure site ie banking, if it is only setup for straight load sharing. if you log in using one ip and the next request goes through ip 2, the banking will kick you off and you have to restart.

we have over 20 computers using 2 adsl 1 lines at around 2.5mb/s, it's still sometimes slow but does seem to route traffic to the right one with the settings fiddled with.

there is one ISP that does line bonding i think, not sure who atm.

get a dual wan router and connect it to one adsl service.
get another router and connect it to the second adsl line.
run a network cable from router 2 to the second wan input of router one.
you can then connect your devices to either router 1 or 2, depending on your needs.

make sure the dual wan router supports load balancing and fallback...
