So Friday was pretty rough. I woke up to find both my Comcast TV and internet completely down—there was supposed to be maintenance at 7 PM, but I had no idea. Then my T-Mobile signal vanished for seven hours while they were supposedly testing 5G support. Since I rely heavily on work from home, that was a big hassle. I ended up going to a client’s office to keep things running. When I got back, nothing worked. To sum it up: I need a backup internet solution that blends in with my setup. I have a Nighthawk Netgear router handling my wired gear and also connect to an internet modem (not a rented Comcast one, but a Motorola MB6800). I checked this Linksys Dual WAN option: https://www.linksys.com/us/p/P-LRT224/. The question is—will it function? What setup would make the switch to another provider seamless? Can I identify which provider failed during an outage? Is it possible to designate a primary or secondary provider in the dual router so it prefers one and falls back? And can I enable DYNDNS in this scenario too? Thanks!

Your Netgear Nighthawk model that supports OpenWRT or similar firmware already offers failover through adjustable WAN ports. You can set one LAN port as a backup WAN port and connect an Ethernet cable from another modem to use during failover. This setup won’t be as robust as dedicated load balancing hardware, but it will function.

Unfortunately, the current system lacks this feature

Do you have any information about possible solutions? Also, can a different LTE-enabled router be connected to the Dual WAN unit while keeping your Netgear router active for DHCP and DNS through the dual WAN setup?

It seems unlikely this will function as expected. LTE will likely use carrier-grade NAT. It's uncertain whether DNS can work under those conditions since the IP address you're using is shared among many users on the network.

That is an excellent point. I am not even sure how I managed to forget that altogether! It's been a tough week. I think that would be ok temporarily. I am planning on using, after discovery, an LTE 4G backup router and use a mobile provider for backup and plug that device into the dual WAN router. thoughts?

It seems like you're suggesting something might be possible. Would you like to elaborate?

Some routers can handle multiple tasks like Mikrotik does. I wonder why redundancy is important here. With two ISPs and a 4G plan, your monthly costs will rise significantly, especially during outages. For example, major disruptions could cost you thousands, even after just one incident. Large companies start considering three WANs to ensure zero downtime, which can cost around $5,000 in losses.

He requires two ISPs, yet he can only obtain one direct connection. Thus, 4G LTE seems to be his sole choice.

Understood, I see. It looks like you interpreted it as two lines with four groups.
