SuperHub subnet

[IntoTheVoid]

I've just taken delivery of my SuperHub and it's default ip address is 192.168.0.1, whereas my previous Netgear router was 192.168.1.1

Why would they set different subnets? It makes swapping these devices really difficult as a number of my devices do not use DHCP.

I tried changing the default subnet of the SH but it complains that it can't have the same subnet as the guest network. But (as far as I can tell) I can't change the subnet of the guest!

Anyone know how I can do this?

Oh, and when I rang to activate my SH and gave them the MAC address they had no record of it and told me I would be without a connection for 24 hours while they sorted it out.

Grrr!

There is no common default subnet range. All that is common is the 192.168 bit after that anyone is able to use anything. Indeed at work I've set a LAN range that intentionally uses a non standard numbering. Especially when people are using VPN and other connection from one network to another different subnets help to avoid routing confusion.

Unfortunately if you do have to set manual IPs then you just have to accept the hassle of periodic changes. But how often do you actually have to change your network? It's a once on a blue moon thing really. You can have some manual and some auto set IPs in your network, just reserve the manaul ranges from allocation.

To be honest even the 192.168 bit isn't cast in stone, it could just as easily be any private IP space but that's just the most common one

[IntoTheVoid]

Yeah, I get that. It's just *such* a pain. I know it's once in a blue moon but that doesn't make it any easier to deal with when it happens.

I guess the guest network is just a DMZ?

Does anyone know what product the SH is based on, or where I could find a manual for it? I must be able to change the subnet of the guest network, ... surely?

TIA,
Steve

The guest network is the opposite of a DMZ.

The SH is based on the Netgear CG320x/CG330x supposedly but it's got VM customized firmware on it so manufacturer's original manual may not be relevant.

And as for fixed IPs, if you're going to use manual IP assignment instead of automatic then you'll have to be prepared to manually assign IPs... It's just something you have to deal with. If you don't want to have to set IPs manually, use automatic IP settings instead of manual.

[IntoTheVoid]

ok, thanks for the info.

For reference, I have set up an SNMP trap on my UPS which requires a static IP address, so there's no getting around it for me.

here you go.

yeah its weird, and this is the first router I have used that even has a guest network.

[IntoTheVoid]

How bizarre! But thanks for the tip; I'll try it this evening.

Hopefully VM will have sorted out my MAC address issue and I'll be able to get online.

[Chrysalis]

yeah so basically goto the page where can edit subnet.

type in 1 instead of 0 but do not hit apply.
scroll down to bottom and hit the clear dhcp cache button and that will reboot the superhub and apply the change.
this obviously moves the guest network to a new ip range, my guess is it probably gets bumped to 192.168.2.x

[IntoTheVoid]

Yup, I can confirm that works ok. Now my network is restored to its former glory

VM also sorted my MAC problem so I'm online again

All is good. Thanks for your help fellas.

BTW: My SH is a Netgear CG3101D for anyone who's interested.

go to advanced settings and change it then

I used subsets in the past but my needs are simpler now. I have a number of devices I need to be static and more that can be dynamic.

As a result the old netgear router VM provided was set up to start the dhcp range at 32 based on 10.0.0.1 subnet. All the fixed ones were allocated below 32 and everything worked out fine.

I set up the SH the same and although all the devices were on the network ok it turns out that you cannot reference the SH as the DNS server for the static devices, which worked ok on the old netgear router.

I had to enter the VM DNS server addresses directly, so I guess the netgear cd3101d (SH) does not offer the same DNS pass through service as the old one did.

I am pretty sure I am now good to go though.

Curiously, the BT HomeHub3 lets you use the 172.16.x.x range as well. Though both still fall far behind most bog standard standalone routers that let you choose whatever the hell you want (and face the consequences)
