For 2700HGV with v6.x firmware there is a functioning alternative which might be useful for some:
Qwest firmwareI've successfully installed this firmware in one of my 2700HGVs, and it works well, but there are several points to note:
- this firmware contains none of the diagnostic features of the BT firmware.
- there's no means of changing the MTU from its default value of 1500.
- the timezone setting page only offers the 5 US timezones, so the router will always be on the wrong time if you're not on US time.
- the firmware has no VOIP capability (it's really for 2700HG, not HGV).
- Upgrading the firmware resets the router to its factory default settings, so you'll have to set it up again after the upgrade. The default IP address is 192.168.0.1, as opposed to the BT default which is 192.168.1.254; if you want to stick with the latter address, it can be changed but doing so is a bit fiddly.
On the plus side, the wireless power is adjustable (possibly beyond UK legal limits), the web interface isn't as sluggish as the BT firmware, and there's no longer any possibility of BT doing a remote firmware upgrade which might cause problems.
