The BT Home Hub 2.0 is much smaller in size than its predecessor, and the Home Hub 3.0 is even smaller than the 2.0.

Features

 and BT Broadband Anywhere. It can also be used as a VOIP phone through BT Broadband Talk.

The new BT Home Hub 3.0 incorporates the WPS functionality, seen on other routers, which enables you to connect with "one-touch". And also includes Smart wireless, which automatically chooses the channel to give the strongest possible wireless signal.

 in the front of the Home Hub or be used on its own stand. A normal telephone which supports DECT can be used in place of the Hub Phone.

With each Home Hub released up to 2.0, a new phone was made to accompany it:
  • Home Hub Version 1.0 - Came with the BT Hub Phone 1010
  • Home Hub Version 1.5 - Came with the BT Hub Phone 1020 - the only difference between the 1010 and the 1020 was the lack of the colour screen on the 1020, and lack of colour screen based features.
  • Home Hub Version 2.0 - Came with the BT Hub Phone 2.1

Home Hub Version 3 does not work with the BT Broadband Talk service.

The phones are only partially compatible with newer or older versions of the hub - able to make and receive calls, but with loss of many features.

The use of a DECT or Hub Phone was removed from the Home Hub 3.0.

Undocumented features

The Home Hub includes a USB-A port which has no documented function. It has been found that some devices (such as printers and USB mass storage devices) connected to this port can be shared on that Hub's network. Storage devices (hard disks and flash drives) must be formatted to FAT32, and hard disk drives must have an external power supply. It can also be used to charge iPods/phones through a USB cable.

Design

There have been five different versions of the BT Home Hub so far:
  • Version 0.5 — grey (no Hub Phone was available)
  • Version 1.0 — white or black (matching Hub Phone was available)
  • Version 1.5 — white or black (matching Hub Phone was available)
  • Version 2.0 — black (matching black Hub Phone is available)
  • Version 3.0 — black (DECT Phones are not compatible) released on 29th January 2011.

As of mid 2008 BT finished rolling out the black, curved Home Hub 2.0 to all new BT total Broadband customers; existing customers can purchase the new Home Hub or get the new Home Hub as a free replacement for their old white one if they sign a new 12 month contract.

There were two different manufacturers of the Version 2 hub; Thomson make the 2A (Type A hub) and Gigaset (now Sagem Communications, Sagem having acquired the Gigaset broadband business in July 9) makes the 2B (Type B hub). Whilst the looks and functionality appear to be identical, the Type 2A has been plagued with problems relating to poorly tested Firmware upgrades which among other problems cause the Hub 2A to restart when uploading files using the wireless connection.

The Home Hub 3.0: DECT phones are no longer supported, and as such, BT Broadband Talk will no longer be provided as part of BT's broadband packages after 29th of January 2011.

Security

The security of the BT Home Hub has been questioned several times by GNUCITIZEN

. In October 2007, Adrian Pastor warned the security and BT Broadband community regarding critical vulnerabilities he discovered in the Home Hub. The details of such research were released later in November 2007 and demonstrated how to fully compromise (get root privileges) on the BT Home Hub by simply tricking a BT Home Hub user to visit a webpage crafted by the attacker.

Such research garnered a significant amount of media attention and even led to Adrian Pastor being invited to BBC Radio 4 where he counter-argued Dave Hughes, director of BT Wireless Broadband. Mr Hughes argued that GNUCITIZEN's vulnerability research only covered a theoretical attack. Mr Pastor, on the other hand, stated that although GNUCITIZEN wasn't aware of such vulnerabilities being exploited in the wild, the attack is fully practical as demonstrated by the exploit code released at www.gnucitizen.org. Furthermore, Mr Pastor argued that the security of the BT Home Hub wasn't sufficient enough to support the newly-introduced Wi-Fi sharing FON service.

The device has also been known to 'kick' users off the internet if too much data is downloaded in a certain timeframe. This problem was identified on BBC Radio 4's You and Yours Show.

GPL Violation

The device runs software which uses the Linux

 kernel, released under the GNU GPL. As a token gesture and, in an attempt to claim adherence to the GPL, BT have released some source code for the device which can be downloaded here. However in violation of the GPL, BT have not published the scripts necessary to compile and install custom firmware to the device.
