Increase Speed With Two ASDL Modems

[sodv]

I have only one choice for DSL service at my home, a pure broadband line with no voice service. No cable, no satellite, no wireless, no cellular service. Other than landline telephone service, I am "off the grid," not by choice.

The available service is Asynchronous DSL (ASDL) with an Upload Rate of 0.283 Mbps and a Download Rate of 0.576 Mbps.

I have two ASDL lines installed at the house, as follows:
Line 1 operates with a CenturyLink ZyXEL Actiontec PK5001A modem
Line 2 operates with a CenturyLink ZyXEL Actiontec PK5001Z modem

Line one is not in use, line two is in use.

I would like to combine the 2 modems on the LAN side for increased speed. In other words, my download data and upload data would be "split" between the two modems for increased time response.

Now I need some advice.

First, is it feasable to split the download and upload data between the two modems for increased speed?

If so, do you have any suggestions at to what router or device is best suited to for this application?

I have researched as follows, a TP-Link TL-ER6020 SafeStream Dual-WAN VPN Router, and a TP-Link TL-ER6120 SafeStream Dual-WAN VPN Router, both for sale on Ebay at much less than retail cost, but will purchase what is needed based on your advise.

Whatever you do, you still only get fed data at those speeds.

You can have two separate services - one through each modem. One pc can run off one. Another pc off the other.

You won't get two services going to one pc at the same time.

Check with your service provider.

You can run 2 ISP connections at the same time but you can not combine them to make a larger single stream. For example you could watch 2 lower def videos off yourtube but you can not watch a single hd video using both connection combined.

A Dual wan router makes this easier but it does not combine them. You can do it manually with the ROUTE command in your PC. What you do is use 1 of the DSL routers as your main on say 192.168.1.1 Then you assign the second DSL router to 192.168.1.2. Make sure this second router has DHCP disabled.

Now you machine by default will send all the traffic to 192.168.1.1 because there is a 0.0.0.0 route. What you do is put in route commands for each site you want to use the secondary connection and set the nexthop to 192.168.1.2. So say some site has a ip of 123.123.123.123 You would issue ROUTE ADD 123.123.123.123 mask 255.255.255.255 192.168.1.2

This tends to be very tedius and dual wan routers will help a little. You still many time ends up having to manually tell the router which IP go which ways. Some try to load balance the traffic but they can cause huge issue. One of the common ones is you were to play a game and it used one connection for the logon server and a second when the game opens. You have now attempted to connect using 2 different IP and the game system will detected it as a hacking attempt. Even simple sites have this exposure which makes it very hard to get this to work well even when you manually tell it which connection to use.

Do polar bears go past your house? You must be remote.

A Dual WAN router or called Load Balance Router allows a router to use multiple paths to a destination when forwarding packets. With the ability to connect up to two Internet connections, the total available bandwidth doubles in capacity and therefore provides a tremendous increase in network efficiency and user productivity. Dual WAN ports also provide a failover response mechanism; if one Internet connection goes down, the other automatically takes control to ensure continuous network uptime.

Most dual WAN routers such as Cisco routers are based on standard routing protocols, such as Routing Information Protocol (RIP), RIPv2, Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), and Interior Gateway Routing Protocol (IGRP), or derived from statically configured routes and packet forwarding mechanisms. Other popular WAN Routers are XINCOM Twin WAN Router, DI-LB604.

?? and your question.

I assume this is a cut and paste of information you found someplace. None of this applies to consumer routers attached to the internet. The only routing protocol you can run on the internet is BGP and you need your own registered AS number and IP blocks to get that. It also is not generally setup to do load balancing by packet.

You can not load balance 2 consumer internet connection because you are running NAT and you have 2 different IP address. It just can't work it is fundamental to how TCPIP works. You can not have 2 ip addresses representing a single session.
