Unlocking BT 2Wire 2700HGV Business Hub (wireless router)

I've forgotten my System Password

 

BT v5.x firmware

For brand new hubs, no System Password is set up by default on hubs with BT v5.x firmware.

If a system password has been enabled and you do not know what it is, or you have simply forgotten it, the only option is to perform a factory reset.   If you reset the hub, ALL configuration settings will be deleted and you will need to configure the hub again.

Refer to instructions at the bottom of this page for how to factory reset the hub.

 

 

SingTel v5.x firmware

For brand new hubs, no System Password is set up by default on hubs with BT v5.x firmware.

A password  '2wire'  is required to enter the Management console:    http://home/mdc

If a system password has been enabled and you do not know what it is, or you have simply forgotten it, the only option is to perform a factory reset.   If you reset the hub, ALL configuration settings will be deleted and you will need to configure the hub again.

Refer to instructions at the bottom of this page for how to factory reset the hub.

 

 

BT v6.x firmware

For brand new hubs, the default System Password corresponds to the serial number which can normally be found on the label attached to the hub.

Note that if the used hub was upgraded from previous v5.x firmware, the System Password corresponds to whatever was previously configured with the previous v5.x firmware.

If a system password has been enabled and you do not know what it is, or you have simply forgotten it, there are two options. 

You can either perform a factory reset.   If you reset the hub, ALL configuration settings will be deleted and you will need to configure the hub again.  Refer to instructions at the bottom of this page for how to factory reset the hub.

 

Alternatively, if you wish to keep all settings but simply wish to change the System Password, you will need the default WEP wifi security key which can normally be found on the label attached to the hub.

                       

                            

 

 

How to factory reset the hub

To factory reset the hub, switch on the hub and wait at least 3 minutes for it to start up normally. 

Then insert a pin into the Reset hole at the rear of the hub and hold it there for 10-15 seconds.

The Power light will change from Green to blinking Red. When it changes to a solid Red, you may remove the pin. It will take up to 4 minutes for the hub to start up again.

The hub has now been returned to factory default settings.






How to recover the serial number

(New 27 Jan 12)

Graham D. needed to recover the serial number for a 2700HGV running BT v6.1.x firmware. The label on the hub had been removed so both the serial number and default WEP key were missing.

He discovered the procedure described here for recovering the admin password for BT Home Hub v1/1.5 also worked on his 2700HGV. The early Thomson made BT Home Hubs used the serial number for their default admin password. The serial number for 2wire hubs running BT v6.x firmwares is also the factory default admin password. I can confirm too it works on a 2701HGV-C with BT v6.3.x firmware.



Basically, using any web browser (works with IE, FireFox and Opera), and ensuring your computer is using the hub's DNS server, point the web browser to this URL:

https://apps.home

Then view the security certificate of the above page. You should find the serial number buried in the 'Issuer' field.



Oops ! This is clearly an oversight by 2wire when they introduced using the serial number on BT v6 firmwares for the default password and went to the trouble of removing the serial number from the System Details menu.



Security Advice: Always change the factory default password on the hub.
