Apologies if I am asking something that already has an answer but I’m struggling with the terminology to use when searching for what I want to achieve!
I have an existing network at home which used a standard ADSL connection for internet access using a TP Link Archer D9 modem router and a powerline wifi extender to cover the far side of my house. I am now using 3 mobile broadband and I want to keep the existing setup with the Archer doing all the routing/DHCP etc.
I have a Huawei E3372h dongle which I have got working with the MT300N. I want to connect the MT300N into the network via another powerline ethernet adaptor to have it in the best position for mobile signal. I would like the MT300N to essentially act as a modem and have the Archer do all the routing/DHCP etc.
I think all I need to do on the Archer is set it into router only mode and set the default gateway to the IP address of the MT300N?
I’m struggling more with how to set up the MT300N, I want to disable DHCP and have it doing as little as possible. I seem to see double NAT being mentioned as an issue with this setup also, is it possible to disable NAT on the MT300N as well?
