Smart hub 2 installation

Hollymatth — Thu, 21 Aug 2025 11:14:29 GMT

We are receiving a new Smart hub 2 from BT as part of the digital voice upgrade. We currently have the main Smart hub in the house and a second hub (TP-link) in a home office connected by Cat6 cable from the house to office. Do we need to make any changes to the second TP-link hub when we install the new Smart hub 2 or will it continue working? I have read that the IP address of the second hub should be different and DHCP turned off, so am assuming that as both these changes have been made already for the existing network, the TP-link hub should just continue working? I haven't posted to this forum before so apologies if this information is already available. Many thanks.

No changes required, it will continue to work as before.

On a separate note, you might want to change the WiFi SSID (network name) and password of the new hub to that of the old one to save changing all your devices.

Thanks very much for such a quick reply! I'll look at your suggestion too as would save changing every device as you say.

Did you manage to get it working?

Presumably, why wouldn't they?

Apologies for taking so long to reply. Yes we just had to plug in the new hub and the second hub continued working, as advised by licquorice. We didn't follow the second suggestion to change the name and password of the new hub to the old ones but in hindsight, we should have done, as it would have saved time changing all our devices, and there were some issues with old devices. Hope this helps.

Thanks for the reply. Before the Digital Voice upgrade I had a modem and an Asus router as my setup. After the upgrade I had to use the SH2 as part of the upgrade and my modem was now obsolete to the whole process. I followed the advice from a post in the BT forum and I had to reset the SH2 and Asus router to factory settings. I'll give it another try and let you know.

You are comparing apples with oranges. @Hollymatth setup was simply replacing one router with another. You are replacing a modem with a router, an entirely different scenario.

Ok so what advice can you offer?

Depends what you want to achieve.

Do you want the Asus as a router or simply a Wireless Access Point?

The Asus is part of a wireless mesh system so I guess as a router is the best.

I'll probably have to disable the wireless feature in the SH2.

The Asus needs to be set up with a different IP subnet to the hub.

Set the Asus WAN as type static IP address and give it an address of 192.168.1.10 and Gateway 192.168.1.254

Set the Asus to use 192.168.2.xxx as its DHCP subnet.

Connect a hub LAN port to the Asus WAN port.

You will then have 2 subnets, you can either use both or turn off the wifi on the hub and just use one subnet.

Thanks for your help I've got it working.

I couldn't find 'Set the Asus to use 192.168.2.xxx as its DHCP subnet' option though but it's working fine.

There wouldn't be an option for it, as such. It is something you would have to configure manually.
