Establishing connections on your device without using a router.
Establishing connections on your device without using a router.
The IP address provided by the router has definitely shifted, which is why I can't establish a connection.
You're thinking about a setup where you connect the old router directly to the switch, letting it handle DHCP and other features. Then you link the new router to the old one for internet access. In theory, if everything works, you'd just lose the internet connection from the new router. It might function, but reliability could be an issue.
Have you explored assigning a fixed IP address to every client and directing the gateway through a device with dual Ethernet connections—one linked to the switch and another to the router for internet access?
If you go inside the router it should tell you what it changed to. Once you're back in give it a static IP then remove that address from the DHCP pool. No, that wouldn't work. If one fails the whole network goes down. In enterprise environments there would be a managed switch or other managed device that would have 2 ports configured in fail-over or link aggregation. These ports would go off to two separate modems often from different providers so at any time if one disconnects the other immediately takes over. The other port(s) on the switch/like device would go off the rest of the local network. This is often seen with modems setup in bridged mode and a router that supports 2+ WAN interfaces.
