TalkTalk D-link DSL-3782 router as modem only, with a Netgear AX1800 as router.

[roger159]

Hi all, I'm having issues setting up my D-link DSL-3782 router as a modem only. I have turned off wifi and DHCP on the D-Link but cannot get internet via wifi or ethernet after setting up my AX1800.

Any help gratefully received.

The other option @roger159 is to connect a LAN port on the 3782 to a WAN port on the 3rd party router.

The advantage is:-

You keep the full functionality of the Netgear, rather than just consigning it to be a wireless AP.

The disadvantage is:-

You have created a double NAT environment. This is not an issue if you do not need to use port forwarding, but if you do, then I can talk you through configuring it.

Configuration:-

In this case disable bridge mode, which disables all routing within your Netgear anyway. Then set the Netgear to have an IP address that is not on the 192.168.1.0 IP network (perhaps 192.168.2.1 with a subnet mask of 255.255.255.0). Then re-enable the DHCP server on your own router.

Hi @roger159 

I should have also said that you might need to put your 3rd party router into bridge mode as well.

Hi @roger159,

OK, so everything will need to be on the same IP network then. With the 3782 in its default configuration and its WiFi disabled, turn your attention to the Netgear. Set its IP address to something like 192.168.1.2/24 and disable its DHCP server. Then in the 3782's DHCP server, set the IP address range to 192.168.1.3 to 192.168.1.254.

Let me know what happens & I'll help you further if you want it.

Hi Keith, thanks for your reply. I have taken an Ethernet lead from one of the Ethernet ports on the back of the D-Link to the yellow RJ45 socket, called "Internet" on the Netgear router as per their instructions.

Regards,

Roger.

Hi @roger159 

@Michelle-TalkTalk has asked me to help you. Exactly how are you connecting them together in respect of an Ethernet cable? Is is LAN on the 3782 to LAN on the Netgear, or LAN on the 3782 to WAN on the Netgear?

Morning,

@KeithFrench - Is this something that you can offer any advice on please?

Thanks

Hi Bill, The Netgear router needs a modem which the D-Link should provide, but it doesn't function.

Who makes the AX1800. And why don't you connect the AX1800 directly, without any D-link DSL-3782. I think I've heard that the D-link DSL-3782 is quite an old model, previously used by TalkTalk.

EDIT: oh, I just noticed, it's by Netgear.
