Unidentified network from switch

I just purchased this D-Link router today, as I had DSL internet last week and now have Cable internet. When I had the dsl modem it would connect to the switch and all my ethernet ports were working, since I switched to cable I was told I need a router in-between the cable modem and the switch. I have followed the instructions that come with the router but with all that I still cant receive a connection through ethernet. And the settings on my cable modem I haven't touched since I don't really want to mess things up

Ok I will give that a go. Will be back to report any issues

My cable modem is a Hitron CGN2-ROG and my switch is a D-Link DES 108. I also got a D-Link DIR-820L router and they are connected like so

Modem(Hitron)>Router(Dlink DIR)>Switch(DES108), wifi is fine but when i connect to the switch i get unidentified network. Also with my ISP I only recieve 1 IP address.

The actual problem is that the Hitron CGN2-ROG isn't just a modem, it's a modem/router and has DHCP functionality.

You don't actually need to use secondary router in this case unless you want to use it as a switch or access point, in either case you would need to turn off DHCP on D-Link router, then plug into the Hitron's LAN port, it will eventually pick up an IP in the correct subnet from the Hitron at which point you can use the D-Link router as a wireless access point or a wired switch.

Just look at the App diagram in the link below, you can clearly see that the Hitron is a modem/router as it's supplying IP's to everything in the network yet there is no other router showing up.

Thank you for pointing that out chev65. I didn't look at the hitron.

As chev65 pointed out you don't need a second router apologies i didn't investigate that.

If you do need a second router set to Automatic DHCP.

This is the first thing I look for anymore as Windows has no such problems with machines seeing each other on a properly configured network. Unless of course the time/date settings are out of sync.

It's becoming a big problem with the ISP's handing these combo units to everyone and then not mentioning they are using a modem/router not just a modem which completely changes the network set up requirements.

You would need to turn off DHCP on the secondary router although the Op was misinformed about the secondary router requirement, it's not needed in this case unless they need another wireless access point or another wired switch at some point in the network.

This thread is now solved despite the fact that the OP may not know it yet.

SO i do not need the dlink router? I can connect my hitron straight to my dlink switch and disable dhcp on the hitron and everything should work?

Edit: Looks like i will have to use the dlink router because i put my hitron to bridged mode and now i cant access it.

You need the Hitron because of it's modem functionality. If you use the D-link you would need a stand alone modem.

The previous advice from the ISP was incorrect. There is no 2nd router required here at all.

The Hitron should work in bridged mode but only if the D-link has DHCP enabled because bridged mode bypasses the DHCP/gateway on the Hitron.

If the Hitron is stuck in bridged mode then perform a 30 30 30 reset to return it to default settings.

The ISP has opened quite a can of worms here and for no apparent reason.
