dsl to cable, do I need a different router?
Hi, thanks for viewing my thread. I just switched from DSL to Cable. I ran 4 computers through my Netgear FS605 router when on the DSL. Now on Cable the router will only run 1 computer at a time. Checked with Comcast, things are fine through the modem. All the router port lights for the PC's blink in unison. Are there DSL only and Cable only routers? I see DSL/Cable routers advertised making me think if there are "combo" routers maybe there are singular routers? Need help please as "who's turn on the computer" is wearing thin.

I've not heard of a router that cares whether DSL or Cable or whatever is feeding the ethernet cable connected to its WAN or Internet or Modem port.

Maybe if you tell us whether the router gets its WAN IP automatically from your ISP, whether your computers are using static IPs, and what you now need to do to switch from one PC having internet to another somebody can think of somethin'.

My assumption:
Your router is still configured for your old DSL access, and this configuration is not working for your current cable ISP.

My suggestion (these steps are ordered):
1. Unplug the modem (from the electrical source).
2. Shut down your computers.
3. Reset the router to factory settings; typically you do this by holding the reset button (this button may be recessed and require you to use a paper clip or toothpick) for at least 10 seconds until LEDs start flashing; give it a minute or two for the lights to stop flashing; unplug the router.
4. Using a known good ethernet cable connect the modem to the router; use the same port that you previously used for the DSL modem, probably identified as WAN or Internet or Modem port.
5. Connect one or more computers to the router's LAN ports.
6. Plug in the modem.
7. Plug in the router.
8. Boot up your computer(s).

At worst, your router is now in a known state and if it still does not work you can do set up like it was new just out of its box.

Did you reset the router to factory defaults? That should run with a standard DOCSIS compliant cable modem.

Are you sure you have the broadband modem plugged into the WAN port? Getting only one computer on-line is usually a symptom of connecting the modem to the switch side of the router.

Open a DOS window and type:

IPCONFIG /ALL >C:\RESULT.TXT

Open C:\RESULT.TXT with Notepad and copy/paste the entire results here.

I just looked up your "Netgear FS605 router." Couldn't find it. What I found was a Netgear FS605 SWITCH. A 5 port switch. Like John explicitly pointed out, getting only one computer online at a time indicates that the modem is plugged into a LAN port. Since your "router" seems to be a switch, it has only LAN ports. Your ipconfig shows all public IP addresses; just what you'd expect if your computer is getting them from your ISP rather than a router.

If you want to share one internet connection with multiple computers you need a router.

Thank you guys for your time and helping me!
