how to connect 2 seperate dsl lines to make 1 faster line?

Question

i have 2 seperate dsl internet modems both are seperate lines coming in from my isp i live in a rural area where speeds arnt that great so ive supscriped to 2 seperate lines meaning 2 seperat modems and i want to connect both to make 1 faster or double the speed line like hooking up a router that has 2 wan ports can anyone help me with this thanks

Answer 1

For full balanced operation across two separate DSL connections, you will need an industrial strength router that is capable of load balancing across the two connections. You will also need to get the cooperation of the ISP so that they can service your two DSL lines with load balancing and sharing a single public IP address. Packets arriving out of sequence should not really be a problem for TCP/IP, but can be significant to UDP traffic if you have any.



If you have significant traffic from different web sites that you use regularly, you could look at a configuration using routing tables to segregate traffic through the two DSL routes.



Set up two normal domestic routers on the same sub-net but with two different private IP addresses. Connect the two routers together by linking a LAN port on each router to the other one with a cross-over cable. Turn off DHCP in one router.



Now for high traffic computers, set up routing tables so that certain sites are explicitly routed through one router, and a default route is set up to send all other traffic through the other router.



Any computer that uses normal DHCP services to get its addresses will automatically use the router that still has its DHCP service enabled.

If they are separate connections, yes that you could bridge the connections, but it will require a linux or BSD running procedure to do it accurately. (DD-WRT (an open-supply, linux-headquartered substitute firmware) firmware walking on a compatible router like a linksys WRT54G router will work... Which you could re-assign one of the most interior ports as a 2nd external port and bridge) It will not particularly offer you a ten MBit connection, inspiration... You'll be doing load-balancing... If you are downloading a single file from a single server, your entire traffic is going to be going over a single 5MB connection, nonetheless for those who then go to browse the web even as downloading, the browsing would go through the 2nd line automatically... Or in case you are downloading 2 records the weight balancing would use one connection for 1 file and the 2nd connection for the opposite. You must see a speed increase on the whole, but not all.

You cannot get anything "faster" that way. A two WAN router simply does load sharing - if one line is busy, it uses the next line. However, applications like IE or other web utilities use only one line at a time because you have to connect to the remote IP address from a single IP address from your house.

There are a few torrent applications that may make use of load sharing lines, but this is not common.



Basic thing is, you cannot use two different lines, with two different IP addresses to connect to one web site per application. The web site does not know how to send data back, except to one IP at a time. In other words, web sites are not built to accommodate "split" requests. When you start a download, the web site sends data to one and only one IP address because it has to get acknowledgements from your PC for every packet.

You need a router that supports this operation. I have no recommendation for an off the shelf consumer router that does this, if there still are any (this used to be a common problem). You can use beige box hardware and something like pfsense to make a router that does this. There are some drawbacks though - packets will arrive out of order which will cause TCP to slow down your connection to any one service to correct the issue. There are other problems that start to negate the benefit of shotgunning connections like this.



You can search for "Dual WAN routers", or "Shotgunning routers" to see if there are any available in your area.



When this was popular (before 30mbit/s cable was common), these routers could be had for $150. Now, I have not seen one in ages.



(also: JGA1RE-3F, I gave you a thumbs down in error. I apologize.)

Answer 5

In theory you can through a process called bonding.



However, you need special equipment (expensive) and the cooperation of your ISP (unlikely).

Answer 6

If it's possible, it's not going to be easy or cheap.



You would have to set up an internal network utilizing both lines as your up and down stream. This is difficult because as the information separates into packets and is sent out, it will immediately get lost.



Problem #1 - How do the packets negotiate and decide which exit to take?

Problem #2 - Same as problem one, but in reverse. How do the packets decide which line to come back on?

Problem #3 - How do the packets get organized and reassembled on your internal network and then error checked?



I Would pay for higher internet speed. DSL can get up to about 12mbs down and 1.5mbs up. That's good for about two hardcore gamers. Some ISP will offer you the ability to fine tune you stream, say 10 down and 2.5 up for example. Look into that too.
