The current home router is currently set up as the LAN gateway on
192.168.1.1 and it's set to get the WAN Internet IP address from the modem, and it's set to hand out DHCP addresses from 192.168.1.2 to 192.168.1.254.I've just now configured a new replacement router the same way by connecting it to the Ethernet port of my Windows PC & duplicating the setup that was on the old router (as much as was possible).
I'm going to swap them, but I might lose my Internet so I ask now.
After I replace that current router with the new router, then I have an extra router which I'd like to make some kind of future use of somehow.
I guess the simplest task is to re-use the spare router as a switch, right? (I don't really need the extra four LAN ports but why not add them anyway?)
But how would I turn the old router from routing into a "dumb" switch?
Do I change the old router IP address from 192.168.1.1 to a static IP of something unused in the range of 192.168.1.2 to 192.168.1.254 or do I let the replacement router (which is set up to hand out DHCP addresses in that range) do it?
Does it matter what IP address I set that new "dumb" switch to?
Mainly I'm asking (before I switch over) how to turn the now spare router into something useful, such as a dumb switch (to get four more ports).
