A boring wifi IT question
bparkison041 wrote 05/04/2020 at 00:41 • 0 pointsWe just got fiber optic, and there's a network switch? Im not sure how fiber works, but in the switch there's a LAN port, and that goes into a "+WAN" port in my modem/router combo. I would still be able to have a backup, which used to be my dsl modem. My question is can I still use dsl? The LAN is an ethernet connection, is it as easy as buying a dsl to ethernet adapter or something? Im new to anything other than dsl, so im not sure. Any help is appreciated

Maybe a diagram would help?
A DSL to LAN adapter is what a DSL modem is. While it's possible to have two WAN interfaces going into your premises if you're willng to pay for both WAN interfaces (will the DSL be still active after the fibre is switched on?), the issue you will face is routing. You're going to have to reroute all Internet traffic to the backup router to cutover. That involves route editing, unless you have a fancy router that can autoroute or even load balance.
I have doubts as to whether you will actually have both fibre and DSL active and without paying for it. Where are you?
Are you sure? yes | no
I played around with it a bit and realized the LAN on the network switch could be directly connected to my ethernet port on my PC, which is all I needed the modem for. Not sure why or what I did but I got it

What you call a fibre switch might be a router/firewall. But if it isn't then connecting the LAN output from that to your PC will not be firewalled so make sure your PC has a firewall active.
