[SOLVED] - Error: Network device is not present - BT HomeHub 5a

If you have your old modem, could you set it in bridge mode, connect it to HH5 WAN and put your ISP udder and pass in HH5 and see if it works?

For physical settings, I select 'Custom' from the dropdown and entered ‘dsl0.101’. For the username/password I entered bthomehub@btinternet.com and 'bt' respectively.


I can't find any information online about this error I'm getting.

Also, can anyone confirm that I'm not meant to have anyting in the red WAN socket (that's for the modem as far as I know..). The DSL cable I have just goes into the smaller grey socket.

Your device is an all-in-one modem/router. You can connect it directly to your phone line (well, filter) via the DSL port as you did, or you can connect it to another modem, in which case you will likely use the WAN port.

It would help if you tell us if you had/have an older modem that you can try.

By the way, is good practice to mask out your MAC address when posting screen shots.

I have the standard BT Smart Hub that I could use if that'll do? That's also an all-in-one.

I have masked my MAC, thanks for letting me know.

You could try connecting the Smart Hub DSL wall, and then Smart Hub LAN to Home Hub WAN; and you set your WAN interface in OpenWrt to DHCP. This is to test the Home Hub WAN port and make sure it's working (and also to make sure that your internet is working!)

Just to be sure, you were not trying to have both connected to the wall at the same time, right?

Once you confirmed that your line is working, could you double check your xDSL settings with those in your Smart Hub? (My OpenWrt router doesn't have xDSL modem, so I don't know much about xDSL settings in OpenWrt).

Have a reading through this https://openwrt.org/docs/guide-user/network/wan/isp-configurations, under UK VDSL, I imagine. You should use your actual username and password given by your ISP, obviously.

Yes, this is the correct set of parameters.

In your Status -> Overview page, could you scroll down and show the DSL Status report?

Testing an ISP branded all-in-one device as bridged xDSL modem in combination with the xWAN port of the BT Hub is kind of orthogonal to the original question (of using the BT Home Hub 5 Type A in an all in one capacity). Given that these devices usually don't support a pure modem mode and the additional effort of switching the BT Home Hub 5 Type A's modem off and into xWAN mode, I would suggest to avoid investing time on the side lines (there isn't a whole lot to be learned, for the amount of mess involved).

My suggestion would rather be to retain your ISP modem-router as it is, so you have a safe fall back to reach the net, make sure to equip the BT Home Hub 5 Type A with a vectoring enabled firmware (which OpenWrt can't ship for licensing reasons) and then to follow the documentation carefully, whenever you've some spare time - ideally coming from a fresh factory reset (as previous attempts might have left cruft getting into the way).

For clarity, I wasn't suggesting changing the Smart Hub to bridged setup; I was suggesting using it as it's an connecting the Home Hub 5 to it as DHCP client via the WAN port; that's easy enough to check and would help with confirming that both the line and the router are working (apart form the DSL side of course)

Is your DSL cable faulty?
Can you upload screenshot of LuCI -> Status -> Overview -> DSL Status?

The 'Error: Network device is not present' may be new feature added to LuCI in 18.06.2 when using dsl interface.

I see the same error message on a spare hub with 18.06.2 with no cable attached to grey DSL port (Sorry, I can't presently test this spare hub on my live VDSL connection to see if message disappears)

If I use 18.06.1 or 17.01.6, the 'Error' message is not visible on this 'offline' spare hub.

Also, try a factory reset (see section 8 of the guide) to see if it makes any difference as suggested by @slh.

Hi, I'm not sure how to get a firmware with vectoring enabled. From the looks of it I need something from here but I'm not sure which version I need or how I go about extracting it.

If this is the firmware I need, I'm sure I could find out how to get it installed!

Tried this and it didn't work, I didn't have internet access at all.

Thanks Bill, actually I had the same thought regarding a dodgy cable and tried two different cables and two filters. Both worked on the Smart Hub but none worked on the HomeHub.

Still, could you post the DSL status from the Status -> Overview page, please?

Vectoring isn't used in the UK, except perhaps where there were BT trials of it in some areas, but no harm in trying alternative firmware. See section 7.27 of the installation guide for HH5A.

I've tried multiple things and it's always saying 'Network Device not present' except when I first reset it and before I set it to be 'ds10.101', then it says like REQUEST_FAILED or something. As soon as I set it and change the interface it stays as the not present status.

The HH5A is connected to DSLAM as both Line State and Data Rate show valid values.

Can you post the 'wan' section from the /etc/config/network file so we can examine for errors? (eg. use WinSCP as described in section 10.2 of the guide)

btw, it is dsl0.101 (begins with lower case DSL), not ds10.101.

Update: I've amended the guide to make it clear to use lower-case 'DSL'.

Ok, so that worked. The problem was that I'd typed 'ds10.101' and not 'dsl0.101'. As soon as I renamed it and saved, everything worked. Then I set up wifi and everything is working fine.

Thanks for all your help and sorry for the mistake on my part.

Special thanks to Bill for that guide! It's really useful and informative.


So if you are going to use the HH5A, what are your plans for the Smart Hub?

I was trying to find out if it can support OpenWrt. Currently there is no support, but the is a possibility that Type B might be suitable for support. This can be found out only if the case is opened and the heat sinks are removed to have a look at the internal components and chipsets.

Such process could possibly well render the device useless, so if you are interested, be prepared for that.

It's only Type B that possibility have potential. Type A has no chance.

There was this post where I was wondering about the components of Smart Hub Type B. BT Smart Hub (Home Hub 6) Type B
Unfortunately I am not in the UK and is not feasible to get one where I am.

The Smart Hub is a lot more capable than Home Hub 5, so it would be awesome if it can be supported. If interested, you may respond to the other topic.
