Use your spare BT Version 1 Home Hub as a wireless repeater!

2 home hubs as repeater

New Advice January 2009. Feedback has indicated that the later firmwares, particularly on V1.5 hubs are unstable on the master and causes the master to reset when seeking the slave in WDS mode. As the master hubs are in their factory reset condition, it would seem to be a problem of BT's making, but on that basis I NO LONGER RECOMMEND THIS WIRELESS METHOD. However as one of my most popular pages for those prepared to play with different firmwares and hubs I leave it here.

The Version 1 and 1.5 Home Hubs
This has been tested on V1 hubs using all firmwares available at the time. However V1.5 hubs do exhibit more instability problems than V1 hubs especially on 6.2.6.H.

The Version 2 Home Hubs (July 2008 on)
V2.0 hubs do not have a WDS function and cannot be used as wireless master or slave hubs in this context. HOWEVER I believe that "Universal Repeater Mode" on some other routers such as Edimax EW-7416APn will work as a range extender with the V2 hub, but you will need to experiment (Thanks to Iain H for the info, June 2010)



"Just wanted to say thank you so much for the instructions about setting up a repeater hub, it was so easy with such great instructions, and it worked first time! brilliant!" Ben D. by email 20/11/2008

Other emails have complained that the master hub search for the slave can reset the hub since 6.2.6.H and V1 hubs were released.



The Home Hub is unpredictable! Whereas the following should work, getting the hub to connect to a wifi PC can be a pain at the best of times. The following worked for me but if you are not prepared to experiment and repeat the process til it works you may be disappointed. See Troubleshooting.

The BT Home Hub version 1 and 1.5 are designed to use "Wireless Repeaters" to extend the wireless range. These repeaters must support wireless distribution system (WDS). Any wireless router with WDS can behave as a wireless repeater or wireless access point if the DHCP IP address server is switched off. As there are a number of cheap BNIB Home Hubs on internet auction sites, such a Home Hub can be a cheaper alternative to purpose made repeaters. WDS will only support WEP encryption, not WPA.
The reason is that whereas WEP uses a "static" encryption key, WPA uses a Key Derivation Function where the same passphrase (that you enter in the admin system) can create many "dynamic" keys. Whereas a PC and a Hub can work together to agree a dynamic key, two home hubs cannot do that. It's WDS itself that cannot do that function.

The diagram shows the end product. When it is fully set up the slave hub will simply be connected to the mains power supply and can be put in an attic, garage or wherever convenient so that you can extend the wireless range.



I originally thought that the DECT telephony and some other BT features on the slave home hub cannot be used, however recent postings on theScream.co.uk and filesaveas.co.uk show that by fooling the slave to think that it is on the web it can be done

See my new Repeaterhub Phonepage

I have it on good authority that functions that rely only on ethernet, such as BT Vision, do work without any changes.


The setup

The sequence is important!!
The process is much easier if you have two PCs, each connected to one of the hubs. If you have only one PC you will have to disconnect, re-connect and reboot the PC to each hub in turn.
The master hub is connected to the PC by ethernet during setup, and is also connected to the ADSL filter and the BT Internet system.
The slave hub is connected to a PC by ethernet during the setup and no other connections. I would strongly recommend against trying to set up either hub wirelessly as it causes major headaches. Always use Ethernet cable to set up initially.


Reset both hubs to start

If you have many complex settings already in the master hub you may not want to do this, but some settings may prevent repeating successfully. so I recommend starting from a clean slate by doing a "hard reset".
On the original V1 hub (shown) do this by holding in the wireless association button on the back for 15 seconds or so, until all lights come on and a click is heard, then release the button and wait for the lights to come back as follows:-
On the master hub which is connected to a PC by ethernet cable and connected to the ADSL wait for the Broadband, Internet and Data lights to come back on steady. The phone light will only come back if you have Broadband Voice and also you reactivate it at www.bt.com/bbv.
On the slave hub which is connected to a PC by ethernet but no ADSL connection wait for the data light to come back steady.
In either hub the wireless light may also come back.
You may have to reboot the PC to regain access to the hub after a reset. N.B. Despite some web postings, NEVER turn off the power to the hub during a reset, or indeed at any time whilst the lights are flashing!

If you have one of the V1.5 hubs with three buttons on the side, resetting is a slightly different process - see manual.


Set up Master hub

There is just one thing to setup in the master at this stage - the wifi channel.

You need to go into the hub's admin at http://bthomehub.home . Follow the instructions to create the new password if you are on recent firmware.
Click on “advanced”, then “Continue to Advanced”
If you are asked for name and password use name "admin" and your new password if you just changed it.

In Configuration/wireless/configure section make a note of the channel that the hub is running on and change it to MANUAL, then set to that same channel. Hit Apply
Also in Configuration make a note of the SSID of the hub, (also printed on the hub's back label)
In Wireless Security make a note of the WEP key of the hub, (also printed on the back label by the SSID usually).


Set up Slave Hub

You are recommended to use firmware on the slave for best results, but may not be strictly necessary (see article)

Connect to the slave hub by ethernet (if necessary disable wireless on PC)
You are strongly recommended for the duration of the setup to set up the PC "network connection" with a fixed IP address of, subnet of, Gateway of and DNS of
Go to to get into hub manager. You may get a screen saying that the hub is not connected to the internet. Do NOT hit the "Try Again" button, but re-enter the IP address, or refresh the browser, to get the hub's Home Page.
Click on “advanced”, then “Continue to Advanced”
User Name on older firmwares is admin and Password is admin. If you have 6.2.6.E or later it's whatever you changed the password to after the serial number window)

If you have older firmware like, change the password.
Go to System, Admin Access, change admin password to mypassword2 (for example).
You will then be asked for your name and NEW password mypassword2 - enter these to continue .

In Configuration/Wireless/ Configure change SSID from BTHomeHub-xxxx to "slavehub" and Set wireless to manual, then when the table appears select the channel that you noted from the Master hub in previous step, then hit "apply"
In Configuration/.Wireless/Security change WEP Encryption key to the same as the master hub's key which you noted earlier, and hit “apply”

In Firewall, turn off the firewall by selecting "Disable" radio button, and hit “next”

We now need to set a fixed IP address in the slave hub within the range of the master hub's private IP address pool.

Click on Configuration/.IP addresses
Uncheck DHCP box, and hit "Apply"
You will see two blank boxes for adding IP addresses.
Type in the first box and in the next box and hit “Add”

Now we need to access the slave hub using its new IP address.
Enter in the browser address bar and hit enter or click Go
You may get a screen saying that the hub is not connected to the internet. Do NOT hit the "Try Again" button, but re-enter to get the slave hub's Home Page.
Now click on “advanced”, then “Continue to Advanced”
User Name is admin and Password is mypassword2
Go to IP Addresses.
You will now have a stack of 4 static IP addresses with the new one you just added at the bottom of the stack.
Delete the top 3 working from the top deleting last of all.
You will get a warning that you will lose connectivity - hit “OK” (You will not lose connectivity because you are using the new IP address!)
In Configuration/.wireless/repeater section scan for wireless access points. (OK the warning message about losing connectivity). Wait a few minutes for it to scan.
In the list tick the SSID of the master hub then hit "apply"

Last step

Reconnect PC to Master hub
Go to or http://bthomehub.home to get into hub manager
Click on “advanced”, then “Continue to Advanced”

Usual name admin and your normal password is used.
In Configuration/wireless/repeater section scan for wireless access points.(OK the warning message)
In the list tick the "slavehub" then hit "Apply"


Now start using it!

Reboot the PC you wish to be connected to the repeater and connect to “slavehub” wirelessly or by ethernet cable. The master hub will issue the IP address to your PC via the slave. You can also connect to the master by wireless or by cable, as you wish.
Use to get into slave hub manager if required
use to get into master hub manager if required



You can connect to either hub, either wirelessly or by cable as convenient.
You can use any wireless channel so long as both hubs are on the same channel. However some channels may not repeat properly depending on the hub and the firmware.
It's also a good idea to keep changed in the master to a minimum to avoid work if you need to reset the master any time.
You can use any SSID and encryption key but must use WEP. The WEP encryption keys MUST be the same on both hubs. WPA will not work in a repeater situation! The reason is that whereas WEP uses a "static" encryption key, WPA uses a Key Derivation Function where the same passphrase (that you enter in the admin system) can create many "dynamic" keys. Whereas a PC and a Hub can work together to agree a dynamic key, two home hubs cannot do that. It's WDS itself that cannot do that function. There are other ways to stealth your network.
Using two home hubs may mean that each has assigned to their USB-A socket and you may not be able to successfully mount a drive on the USB-A without more work, because the PC may be confused as to which is which.

I suggest using different admin passwords as above, as it's easy to lose track of which hub you are logged into.
If you have Firefox or similar,I suggest bookmarking the two hub addresses on the Bookmarks Toolbar.
Advanced: If you need to connect directly to the slave after switching off DHCP you may have to set a fixed IP on the PC, but if connecting to the slave via the master, the master should issue an IP address to the PC as normal.

If you set up and log in with "Root user" access in the slave on as described in the articleyou can backup the configuration of the slave for safe keeping.



Even though BT use it as standard with the Hub, WEP is not the most secure type of encryption. Whilst better than nothing it can theoretically be cracked in 10 minutes if someone is prepared to get the kit together. For that reason when you have the hubs talking to each other you might want to look at MAC Address Filtering , and changing the WEP keys. See here.



Once you have got the setup working, you can experiment with Roaming. That is the PC should automatically connect to the strongest signal and should change to the strongest signal if the first gets weaker. As this is a feature of your PC wireless management I will let you experiment, but I received the following email...
"Using Windows XP to manage the network connections I have set the main Home Hub at the top of the 'preferred order of connection' list with slavehub second. The wireless network connection icon in the system tray gives a status message in a balloon whenever it connects to a network so I can see when it swaps from one signal to the other. It will swap to the Home Hub (priority 1) even when both signals are present.
Whenever it swaps over there is no pre-warning and the transfer completes almost instantaneously, (less than a second) displaying the status change when re-connected (identity of network and signal strength)" Kevin A. by email Sep 2009.


IP addresses

I have recommended as the slave IP address. I changed this from my previous suggestion of .75 as it was a bit too near the working range fo people with more than 10 network devices (and that is not unusual if you have webcams, network hard drives, vision boxes etc.

It has been further suggested to use an IP outside the hub's DHCP range and I know that works fine with no danger of it interfering with the hub's assignment range of to .237

I think it really means use an address either below the private range, or near the top end of the private range, but any IP in that subnet will probably work just fine.



Best plan is to reset the hubs and start again.
If you possibly can, use ethernet rather than wifi to link the hubs (see wired repeater article in Menu)

Try fixing the channels to another channel, but change both hubs!
In extremis, change the slave (or even the master) firmware to (check my homehub index)

Don't write to me - experiment!



Lots of help came from contributors on Home Hub Forum and especially the contributors "nbridge" and "Bramshot".
