1.1 Hardware History
British Telecom (BT) in the UK introduced the Home Hub 5 to their fibre broadband customers from
2013. This is an AC1200 wireless router with built-in modem for ADSL (annex A) and VDSL support, 4
gigabit LAN ports, a WAN port, and one USB2 socket. The stock firmware is locked to BT broadband but will
also work on Plusnet.
The wireless supports up to 300mbps (2x2 streams) on 2.4 GHz band, and either upto 450mbps (3x3
streams) wireless N mode, and/or upto 866mbps (2x2 streams) wireless AC on 5 GHz band. (300mbps +
866mbps = 1166mbps -> AC1200 spec)
The 'Type A' model, which will be referred to as HH5A in this guide, is manufactured by Sagemcom and uses
a Lantiq processor with Atheros wireless chipset. There is also a 'Type B' model, manufactured by Huawei,
and is based on a Broadcom chipset.
There are two other variants of the HH5A supplied by BT subsidiaries. These are called the 'BT Business
Hub 5' and 'Plusnet Hub One'. The only difference between all variants lie with the factory installed stock
firmware. The internal hardware for all three variants is identical.
BT stopped supplying the Home Hub 5 in late 2016, and the Business Hub 5 by mid 2017. The Plusnet Hub
One continues to be supplied to fibre broadband customers, and will probably be superseded by a rebadged
BT Smart Hub, some time in 2018.
