It is claimed, in various places, that the Business Hub (the BT provided 2Wire 2700HGV) is "locked" to BT Broadband but I have found, by practical experience, that is not true.
I suppose it depends on what one means by 'locked'. The custom BT firmware used in the Business Hub is locked in the sense that the user can't change the login details to a different ISP using the regular configuration pages. To do that you have to go to an unpublished hidden setup page or use other trickery. You can read the full details here.
Last two sentences first: Thank you for the URL,
Eric, however I am well familiar with that site. I read every word before purchasing my brand-new, boxed & sealed, BT badged
2Wire 2700HGV.
Now your previous sentence:
"The custom BT . . . regular configuration pages." That was not the case for me! The steps I took, once it was unpacked, were:
(1) Fit stand.
(2) Connected power supply.
(3) Powered it on.
(4) Left it alone for about half an hour.
(5) Connected it to my laptop (running
RHEL 6) via an Ethernet cable.
(6) Established a DHCP connection.
(7) Invoked
Firefox.
(8 ) Entered 192.168.1.254 into the address bar.
(9) Changed the default administration password to something of my own.
(10) Adjusted all the relevant settings,
including my TalkTalk login and password details.
(11) Ensured that all changes were saved.
