Link two HomeHubs together to extend a home network - slave hub and master hub

I've just connected an HH6 slave to an HH5, and an HH3 slave to a different HH5, and both slave Hubs are working fine. The following is a guide to this "daisy-chaining" of two HomeHubs. It assumes basic knowledge on how to use a browser and a Hub in the first place.

Plug just the power lead in to your Slave Hub and switch it on.
Because the slave hub hasn't got a direct connection to the internet, you'll see problems being indicated:

HH3: Power & Wireless lights blue, but middle light for broadband is unlit.
HH5: Light will be flashing orange.
HH6: Light will be flashing a weird pinky-lilac colour.

Connect a computer to the Slave Hub using your favourite method - by WiFi or by Ethernet cable.
You'll be told you have no internet access, but that's fine at present.
Log into the Hub settings page by firing up your browser and visiting internet address 192.168.1.254

 


CHANGE THE SLAVE HUB IP ADDRESS:

HH3 & HH5: Advanced Settings tab > Home Network > IP Addresses
HH6: Advanced Settings (purple box bottom right) > My Network (box) > IPv4 Configuration


The IP address should be showing as being 192.168.1.254

Change the last number to something below 64. Let's say 192.168.1.20

Apply the change.

You'll immediately have lost contact with the Hub, as its address has just changed. Doesn't matter. Close the browser, switch off the Hub, then switch it back on. Wait for it to do its start-up things.

LOG BACK IN TO THE HUB'S SETTINGS PAGE:

That is, use your browser to visit the NEW internet address 192.168.1.20

If you're using Firefox with NoScript, remember to allow scripts for this new page 192.168.1.20, or your Hub Admin password won't work!

 

DISABLE DHCP (Dynamic Host Configuration Protocol):

HH3 & HH5: Advanced Settings > Home Network > IP Addresses > set DHCP Server to 'no'.
HH6: Advanced Settings > My Network > IPv4 Configuration > set DHCP Server to 'no', ie disable it.

Apply the change.

 


YOU CAN NOW CHANGE THE NETWORK NAME, IF YOU WISH:

HH3 & HH5: (Advanced Settings) Wireless > the Wireless SSID box --- it'll say something like BTHub5-XYZ4
HH6: Wireless > Change Settings > Network Name --- it'll say something like BTHub6-ABC3

Changing it to something like BTHub5-SLAVE or Hub5-REMOTE will be useful for helping you remember which network is which, in the days and years ahead.

You can change your network password as well, if you wish to. Also, you can give your 2.4GHz and your 5GHz networks different names, if you feel like it (not on HH3 though). Or even disable wireless completely, if you are an Ethernet-only type of computer guy.

 


DISABLE THE SLAVE HUB's FIREWALL:

The primary Hub does the firewall stuff by default, so the slave hub doesn't need to. Disable the firewall:

HH3: (Advanced Settings) > Port Forwarding > Firewall
HH5 & HH6: (Advanced Settings) > Firewall > Configuration


CONNECT THE SLAVE HUB TO THE MASTER HUB:

Have an Ethernet cable, plugged in to a yellow socket on the Master Hub and also the Slave Hub. (The red Ethernet socket on HH3 and HH5 can be ignored.)

Assuming the Master Hub has an internet connection, you now should be able to surf when connected to the Slave Hub.

If the Slave Hub's flashing light annoys you, it can be turned down or off:

HH5: (Advanced Settings) > Hub Lights --- you can select 'normal' or 'low'
HH6: Hub light control --- various options including switching it off.

Or you might decide to use traditional old black gaffa tape over the light, although that's not so easy on the HH6, as the light is semi-recessed.

Clarifications welcome. Good luck.

Re: Link two HomeHubs together to extend a home network - slave hub and master hub

hi there

 

do the hubs have to have a physical ethernet connection or can they connect wirelessly 

 

 

thanks

There has to be a physical connection.

 

Use a decent third party router with extenal wireless aerials, and you should not need to extend the wireless.

Re: Link two HomeHubs together to extend a home network - slave hub and master hub

This looks like a set up which will work for me, but I do have further questions below which I’d be grateful for any help with

 

i am getting delivery later today of a BT smart hub and am already in possession of the hub 5. I plan to link the two together in the way described above.

 

Q1 which should I have as the main unit and which the slave? My instinct is to use the new smart hub as my main router as I’m assuming it will be “cleverer”?

 

Q2 if I give the hub5 the same SSID and password as the smart hub will my mobile devices automatically connect to the strongest signal or will they just hold on to whichever one they find first?

 

Q3 or am I better giving the hub 5 a different SSID as per above, and telling my family they may need to switch networks if reception is poor depending on where they are in the house?  

 

Q4 If this is the case then I guess that Wi-fi repeaters which do recommend the same SSID and password in their set up must do some other “magic” in order to replicate the same signal?  

 

Thanks  in advance for any help provided.

Sorry, as I said on my website, I cannot help with this, as the article was written by a forum member who has now left.

Probably easiest to use the smart hub as master but not because it is 'cleverer' but because it seems to be averse to having DHCP turned off.

 

Q2 if I give the hub5 the same SSID and password as the smart hub will my mobile devices automatically connect to the strongest signal or will they just hold on to whichever one they find first? They will hold on to which ever they connected to first, there will no seamless roaming. It is better to give each device different SSIDs so that you can tell which you are connected to.

 

Q3 or am I better giving the hub 5 a different SSID as per above, and telling my family they may need to switch networks if reception is poor depending on where they are in the house?  Yes, as above.

 

Q4 If this is the case then I guess that Wi-fi repeaters which do recommend the same SSID and password in their set up must do some other “magic” in order to replicate the same signal?  Wifi repeaters have no magic, the same thing applies to them. It is only 'mesh' systems that give seamless roaming.

 

Thanks  in advance for any help provided.

Thanks for that licquorice.  As you can tell I’m still learning here - what is a mesh system?  And is that overkill or prohibitively expensive?

Other manufacturer's products are available, but the link shows the principle.

Re: Link two HomeHubs together to extend a home network - slave hub and master hub

Thanks again.  I guess that explains the difference in price between the 3 disc set up and a bog standard repeater..
