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

22 Mar 2012: With the announcement of the all new BT Business Hub 3, I have decided to retire this website. The contents and the website will remain, but no significant changes or updates will be made in the future. Thank you to all those who have contributed to the contents on this website over the last few years.

Jan 2014: I had to install a new 2700HGV with v6. to replace a 6+ years old 2700HGV which developed a DSL connection fault. To my surprise and annoyance, the firmware was updated to v6.3.9.63 a few days later. In hindsight, I should have applied Adrian C's fix to block the provisioning server from applying the firmware upgrade as I wanted to see if v6. would resolve an ongoing wifi connectivity issue at the premises.

Feb 2014: The above mentioned hub has now been replaced by a DD-WRT cable router. A 2700HGV (v5.29.117.6) now serves as an inexpensive ADSL modem operating in 'bridge' mode attached to the new router. I've also briefly tested another 2700HGV (v6.1.1.22) in bridge mode which is to be kept as a 'backup' modem. A 2701HGV was also installed to serve as a wireless access point at the back of the small business premises.

May 2015: The 2wire power adapter failed last autumn - we were prepared for this event. We have a couple of spare hubs and repaired power adapters to accommodate any further outages in the next few years.

Aug 2018: All of the download links no longer work. Here is a new link to Dropbox folder containing BT 2wire firmwares:


Jan 2020: The 2701HGV access point could no longer provide reliable coverage to a certain part of the premises two internal walls away. We suspect it was caused by new business moving in next door a few months ago and their wifi. We decided to replace the 2701HGV access point with something newer so we tested an Asus router in AP mode. After a few weeks of testing, we concluded there was no improvement so reverted back to using the old 2701HGV. Now looking to install a new access point into the wifi blackspot.

Jul 2020: The 2700HGV modem and DD-WRT router (using firmware from 2012) has been very reliable since its installation in 2014 into a small business premises. However, this month, there was an unexpected broadband outage. It transpired an old microfilter had been removed from a phone socket which uses same line as the broadband connection, resulting in noise and interference on the line. During fault finding, it was an opportunity to test newer equipment. A modified dual band BT Home Hub 5A DSL modem router running OpenWrt is now installed. If the trial is successful, the 6+ years old 2700HGV and 11 years old Dlink router will be permanently retired. https://openwrt.ebilan.co.uk/viewtopic.php?f=7&t=266
