Having Three WiFi Transmitters / Networking

[grahamsmythe]

Good evening all. I'm hoping someone might be able to give me some networking advice please.

I have a VirginMedia Hub at home - a standard installation 1gb broadband with a Hub 5 - running in router mode.

Along the way, I also have obtained a spare VM Hub 5, plus an VM SuperHub 2AC.

What I'd like to do is turn the spare VM Hub 5 and VM SuperHub 2AC into separate networks that will run elsewhere in our house. Hard wiring them is not a problem.

I'd like the existing VM Hub 5 to publish ip addresses 1-125. The second one to publish ip addresses 125-175, and the VM SuperHub 2AC to publish ip addresses 175 to the end (whatever number that would be).

So,

1. How do I go about that? I'm guessing the first hub stays in router mode, but the others need to go into modem only mode?
2. How do I alter the range of IP addresses that the hub is able to publish?

Any help that anyone is able to give would be very much appreciated.

The spare VM Hub 5 & VM SuperHub 2AC are pretty much useless for your intended purpose.

Consider retail Wi-Fi Access Points or Wi-Fi Routers ( if Ethernet ports are also required ).
You don't mention what the special requirements are that might warrant running multiple DHCP servers.

We have a VM Hub in Router mode + a pair of Wi-Fi APs, the VM Hub provides the DHCP service.
Keeping it simple and reliable was our goal.

"Along the way, I also have obtained a spare VM Hub 5, plus an VM SuperHub 2AC."

How so?

I didn't mention any special requirements as I didn't want to muddy the water and get a million and one different suggestion as to why I should or shouldn't be doing it this way (always tends to happen when you post this sort of thing online).

I'm not sure why the additional hubs would be pretty much useless, as surely they are able to create an entirely separate WiFi signal and connect to the existing VM Hub 5.

Oh Jeez - please. That's not the question I was asking.

If you want to ask me such a thing - either start another thread, or call the VirginMedia Police.

My answer... No you can't do that

You cannot possibly do what you want with the existing VM equipment. Best thing is your own router and wireless access points and possibly a network switch, depends on your layout. You cannot ‘split’ up DHCP requests like you suggest, unless you go to high end business solutions. If you want particular IP address in a location, just hardwired the IP address into the device. If a lot of these devices just IoT ones you need to look for a router that provides VLANs so you can split off these devices, that’s what I have done.

You cannot have separate networks with VM hubs but they can be connected on a LAN to LAN basis to extend your LAN. Or to put it another way: their IP addresses must be in the same range as that of your hub (outside the DHCP range) and have the same subnet mask.

The OP already knew his proposed configuration was utter BS.
