Thanks shtu can I ask if you have used the BT business hub on a normal residential line without having to hack or change the firmware from the standard BT software
Yes, I did. Version 5.something firmware. (I'm trying to remember if it upgraded to 6.something)
I use option 3, but the authentication is the same for all customers, a generic username and password. Don't waste money on an unlocked one, buy a new-in-sealed-box one for less money.
You can buy a secondhand one for under £10 delivered, new-in-box for about £20.
I currently have the home hub V2 and it syncs fine on G992.1 but loses sync at night at times so am looking for a little more stability if possible. I am 4.2KMs from the exchange and it has been again suggested that the business hub hangs on to a lower noise margin at night.
You might be surprised, my line is 9.5Km and I found the HH2 to be as good as the 2Wire in terms of sync speed. The 2Wire does appear to be a snappier, more responsive bit of kit, though it does have one noticeable failing - uPNP doesn't work, so you'll need to learn how to set up port forwarding manually if you have anything that makes use of it.
The main reason I stuck with the HH2 is that I make extensive use of Broadband Talk (which is also a "just works" on the 2Wire), and the 2Wire does not pass the ring signal through from the landline in the same way that the HH2 does.
Have a read through my posts from, ooh, about a year ago when I tried one.
