Turning a BT HomeHub 5 into a Gigabit Switch3 min read

BT is an alright ISP, I get good speeds (150D/40U), never get throttled and have yet to hear anything about my internet activity which involves a fair amount of P2P.. their hardware however is god awful, and the BT HomeHub 5 is no exception to that.
I won’t go into how bad it is because if you’re reading this hoping to repurpose it you already know, the only good thing about it is the 4 port gigabit hub attached to it that actually okay, so we are going to make it into a dumb switch.

Doing this is actually very simple and all that’s needed is to turn off all the services on the HomeHub to make sure it doesn’t interfere with anything else on the network.

Step One:
Reset the HH5. This is just to make sure there isn’t any previous config interfering with this setup.  To do this, make sure it’s powered on and that nothing else is connected, then hold down the reset button at the back with a pin (I use an iPhone SIM tool) for about 10 seconds, until the light at the front turns green and release.

The HH5 should, after bootup, have some orange lights on the front and a blinking “b”, this is fine it’s just complaining about connectivity.


Step Two:
Get an ethernet cable and connect it to any of the 4 LAN ports on the HH5 (yellow ones) and the other end into a computer. The HH5 should lease you an IP using DHCP which is fine, and for me on Windows 8 a web browser popped up telling me the HH5 has no internet connectivity, whatever.

Go to your preferred web browser and go to and you will be greeted with the HH5 administration page as follows:

hh5 portal
Step Tree:
Now you’re administrating the HH5, you want to head over to settings and enter the admin password at the bottom of the page, this is located on the card that sits on the back of the HH5.


Once you’ve done that, press enter and you’re in! Head over to “Hub Lights” and change that to low and apply, this isn’t necessary, but helps make it that little bit less obnoxious.

lights off

Next head over to Advanced Settings > Wireless and turn turn the WiFi off under “Wireless Network Enable” and click apply.


Do the same for the 5GHz WiFi radio, the tab for this is just below the main tab of options.

After this go to the WPS tab and turn that off too, click apply and say yes to the warning.

Step Four:
Now the WiFi is out of the way we can turn off the remaining services.

In Advanced Settings, head to Home Network > IP Addresses;
Give the HH5 an IP that is not the current one incase your current networks router uses, I used, keep the subnet mask the same.
Under “DHCP Server” click the “NO” radio button and apply these settings, you’ll face a warning, accept it and your browser should tell you the webpage is unavailable.

After this you’re done! Plug anything you like into the yellow ports and the HH5 will be a dedicated switch. One of the ports you will probably want to use as an uplink to your current network giving you 3 slots to use for other devices.

  1. Excellent!! – I was actually in the process of typing out a message for this page, which said, “I have followed all the instructions, and it’s still not working”. I had noticed that there was no light (either flashing or constant) on the broadband part, so I was convinced that it was still not working. But as I was typing, I thought I would go onto my network and do a trial, to see what error messages came on the screen. Would you believe it, Safari connected to the internet without any trouble. Thanks for your excellent instructions. I had watched SO many YouTube videos on the same subject, but they definitely didn’t work.

  2. Been through all the steps maticulously. Doesnt work!!! :-(( Orange light statid (not flashing) and b light flashing (orange) HELP!!

  3. Hi, I’ve tried the same technique with a HH4 and can’t get it to work. All the steps as listed complete OK and if I end up with the re-configured HH4 connected to my Mac’s LAN port alone with a regular LAN cable I can access the HH4 on its new IP address (as long as I configure the Mac’s IP address setting manually with the ‘router IP address’ set to the HH4 IP address).

    But if I then turn off the Mac’s wifi and connect the HH4 to my main router via a spare yellow LAN port (the router is another HH4) I can’t get an interweb (or LAN) connection on the Mac.

    Any thoughts?

  4. You are aware that literally everything emits radiation, yes? Of course electronics, including phones, are going to emit some form of radiation but there is no link between this and your health.

    This recent trend in saying so is right up there with flat earthers and anti vaxxers, disinformation and hysteria for the sake of it.

    If you’re going to go ahead and believe such things with 0 evidence because you feel like you know better, then be my guest, just don’t spout that stuff here.

  5. “EM radiation damaging your health is not a thing. If it was, we would all be very, very sick by now.”
    If you say so… for example, you think the SAR rating on mobile phones is a form of superstition, then?

  6. The HH5 wireless is emitting electromagnetic radiation which should be switched off to protect against health hazards when the router I close to you. I.e within 5m.
    How can I easily switch on and off as we use ethernet cable except when visitors come or we want connection away from the cable location?

    • EM radiation damaging your health is not a thing. If it was, we would all be very, very sick by now.

      Please do some research and read papers by scientists that have done extensive research into this and stop spreading false information.

  7. You might want to correct the typo in Step 2

    “Go to your preferred web browser and go to ” as per the screenshot

  8. Hi, Would you be able to use the USB port on the HH5 when using it as a switch? as I have an external hard disk which I used to connect to HH5 when using it as router….if so how to access it?

  9. So you’d connect your actual (say none-BT) router to the repurposed HH5 via one of the HH5’s yellow ports, not the red one? Also do you happen to know if IPTV channels would work on a BT YouView box connected to the repurposed HH5? Any help would be appreciated.

    • Yes, the yellow ones are now switchports, I don’t believe the red one can be used.

      I have never used IPTVs but I have heard of people having issues with them using 3rd party routers with the way BT does IGMP with their routers. I would do some research to ensure that any new router you buy can support the multicasting/IGMP that BT use for their TV.
