Network Switch For Multiple ISPs (alien.top)

TL;DR: Is there a way to have two different (unreliable) ISPs connected to a single network switch, so that when one drops out, the home network is automatically switched to the other ISP?

---

Hi all!

I am a networking hobbyist, and I built out a home network for a family friend of mine living in Mexico. They have an ISP reliability problem I have not encountered before. Their service frequently cuts in and out, and thus they have two separate ISPs to ensure connectivity at all times.

I currently have both ISP's gateways plugged into the same unmanaged network switch. The hope is that if one ISP goes out, the switch will be smart enough to use the other one. In practice, when both ISPs are up and running, the network switch seems to flip randomly between the two of them which causes interruptions on the home network.

I would like to have both ISPs plugged in at the same time so my customer does not have to walk down to the switch swap inputs. Is this functionality I would need a mananaged switch to accomplish?

Let me know what you think, and thanks for your help!

Do you not have a reliable ISP in the area?

What problems are you having with the current ISPs?
