Wireless Access Points (WAP) are often used to improve wireless coverage in another part of a property where the main wireless router is unable to provide adequate coverage. However, an ethernet network cable needs to be installed to connect the new WAP back to the main ADSL router. (An alternative to running a long cable, is to use powerline adapters – these should perform well in most residential properties, but may be problematic in larger business premises which may be supplied by 3 phase mains power)
Note: The DHCP server on BT firmware v188.8.131.52 cannot be disabled, and so it cannot be used as a WAP.
If you are already using a BT Business hub as your main router, then its default IP address is usually 192.168.1.254. If you plan to install one or more WAPs linked to the main router using ethernet cable, then it is necessary to ensure the WAPs have a different static IP address.
The steps below show how to reconfigure a 2700HGV running BT firmware to behave as a WAP. The aim is to set up this WAP to use an IP address of 192.168.1.248 and to disable the DHCP server. If you plan to install a second WAP, you must give it a different IP address (eg. 192.168.1.249 etc)
Use a web browser and confirm your main BT router is at the IP address: 192.168.1.254. The 'home' page should appear as normal.
Now connect a computer to one of the ethernet ports of the spare BT hub which you plan to use as a WAP.
Go to the management console (MDC) if you have BT v5 firmware, or to the home/ page if the hub has BT v6 firmware installed.

Make the following changes shown below for v5 and v6 firmwares:
Save the changes and disconnect the network cable between your PC and new the WAP before you switch off the new WAP.
Now connect an ethernet cable between main ADSL router and your newly configured 2700HGV WAP.
Switch on the new WAP and connect your PC to one of the ethernet sockets on the WAP (or main ADSL router).
Check you can access the home pages for both your main ADSL router and the new WAP in a web browser.
ie. Type home/ or 192.168.1.254 to access the main 2700HGV ADSL router's home page.
And type 192.168.1.248 to access the home page of the new WAP.
If you are unable to access the WAP's home page, you will need to perform a factory reset on the hub and start the whole procedure from the beginning.
You now need to configure the wireless settings on the new WAP. In theory, if you wish to roam between your main wifi router and the new WAP, you MUST use exactly the same wireless settings on both hubs, EXCEPT for the Wireless Channel which must be unique. It is recommended to only use wireless channels 1, 6 or 11 as these do not overlap each other. Shown below are typical settings you may wish to use. Ensure the wireless key is the same on both hubs. Unless you possess some very old wireless devices, I recommend using WPA2-PSK (AES encryption). Use a custom wireless key which does not contain whole words which can be looked up in a dictionary.
Unfortunately, in practise, transparent roaming between a 2700/2701 hub (main router & DHCP server) and a WAP does not work very well where the same SSID is employed – I found rebooting the 2wire hub which is acting as DHCP server temporarily solves the problem. Therefore I recommend you create different SSID for the wifi router and additional access points if you discover your wireless clients have difficulty connecting.
eg. the main ADSL router may perhaps use wireless channel 6, and the new WAP uses channel 11.
Save the settings. Setup complete.
Start up a wireless device and connect to the wireless network. Confirm you have maximum signal strength when it is placed in close proximity to either the main ADSL wireless router or the new WAP, and that there are no problems accessing the internet at both locations.
Single SSID BT 2700HGV hubs are capable of up to 400mW transmitter output when using v4 or v5 firmware.
Dual SSID BT 2700HGV and hubs running v5 firmware are restricted up to 100mW output.
BT 2700HGV hubs with v6 firmware are restricted to 25mW output but you could use Qwest firmware to boost it to 100mW.
BT 2701HGV-C has a default of 75mW output so is perhaps ideal for use as a WAP 'out of the box'.
These are some screenshots if using the Qwest firmware to configure a Wireless Access Point.
Note that the default IP address of Qwest firmware is 192.168.0.1.
You will need to assign a static IP address to the computer, to be able to make some of the following changes.
If you are planning to change the IP address of the WAP to use for example 192.168.1.248, you need to change the IP address first to lower address such as192.168.1.1. Then reconnect to the hub and modify the 'Ending IP address' from 192.168.1.254 to 192.168.1.99 before later disabling the DHCP server. Then you will be able to assign 192.168.1.248 to the hub.
