Hi guys,
I have next to none knowledge of networking and was wondering if someone could give me some advice.

Basically, I work as a programmer in my home, so I need a internet connection always, because of this I have two isp from two different companies called Axtel and TotalPlay, both of them installed their routers and i have internet access in both of them.

Here's the issue, I want to be able to have all my computers in the same lan regardless of which router they're connected to, so for example if my laptop is in wireless Axtel, but my computer is in wired Totalplay I want the laptop to be able to access the files in the wired computer.

Is there a way I can achieve that? If I have to buy stuff please tell me how would they work if you can, because I would like to learn what they do.

Thank you guys!

The largest issue with a multiwan router is how does it know the internet went down. The ethernet ports will never power off. They could attempt to ping something but what happens when you get a partial failure or you get 50% packet loss.

The way this is done is a commercial installation is to run a routing protocol like BGP between your routers and the ISPs routers. It will many time fail quick enough to not even lose the sessions. It is not a option even for a medium sized company though because of the difficulties of obtaining ip blocks and AS numbers.


You can do this manually fairly easily. What you do is set both routers to the same subnet assigning say 192.168.1.1 and 192.168.1.2to the lan of the routers . You plug the...

The easiest, best way to do this is to have everything on ONE router/ISP. Just keep the other router/ISP in reserve, in case your main one goes offline.

At my office (commodities trading) we had 2 ISPs for redundancy, as we could not afford to be down for even a few minutes. We had a Zyxel switch which connected to both ISP's and managed the load. If one ISP went down, all traffic was seamlessly routed to the other ISP. But this was a business class switch (about $1,000 if I recall), and I don't know if consumer grade switches have this capability.

This sounds interesting, I've read something about a router with loadbalancing but don't know if that could work.

Auto failover does not exist in the consumer space. Unless you have deep pockets.
For a one man operation working at home...walking over to the routers and moving the LAN cable from A to B is the easiest solution.
It would only impact a large download that was 'in progress'.

For the OP's situation, I think your solution is the best. I just wanted to point out that it is possible with a managed switch. As I recall, it took coordination with the ISP's and lots of setup time. We also had a dedicated server, backup server, 2 computers for each trader, etc. to make sure we could still trade if one ISP went down, which happened from time to time. Power outages in the building were a whole different matter. For that, we had several laptops with a cellular connection (not sure what that is called - a USB device that worked over the cell connection for internet access).

According to this question and response from the link you gave, the answer appears to be yes, but I can't give you any opinion. https://www.amazon.com/forum/-/TxQYT58YBSU3DP/ref=ask_dp_dpmw_al_hza?asin=B005SYQBN8

I guess for $42 you can find out, and return it if it doesn't work. Another issue would be how hard or easy it is to set up on the software side.

Edit: What do you think USAF after reading the link i posted?

Actually, the real issue would be connecting a single computer to 2 networks, the thing is I have a machine that has a 4tb hard drive and its always on, that machine serves as a NAS storage of some sort, I want to be able to use this computer regardless of which isp I'm connected on, this computer is a NUC and has access to both connections via ethernet cable, but only one at a time since I have only one ethernet input

You can do this manually fairly easily. What you do is set both routers to the same subnet assigning say 192.168.1.1 and 192.168.1.2to the lan of the routers . You plug the lan ports together and disable the DHCP. Now your pc will always use the 192.168.1.1 because it is getting the gateway from the dhcp server.

When you want to change it you just use the ROUTE command and delete the 0.0.0.0 route for 192.168.1.1 and add one for 192.168.1.2 If you want to spend the time you can actually use both at the same time for different traffic by using the same route command.
