BT Business broadband are currently bundling the 2wire BT2700HGV with their lines, which is a wireless router with built in firewall, content management and Hardware VoIP system.

Now this is a brilliant system, as long as at works - but it does have one very annoying “feature.” The BT version of the router actually dials back to base, deposits a serial number or MAC address at the server end and retrieves the username and password set up for the device. Useful if you’re not tech savvy enough to set it up, not very useful if you want to re-distribute the device to a different site, or even want to take a spare one home..

So what can we do about that? Well the only way I can think is to take [this] file and flash the firmware with it. The file is a zip, so you’ll need to decompress to get the raw .2sp file. Once done, the firmware will set the router up as an american ISP. Full details below:

1 Download the file above.

2 Once the router is connected to your PC, go to [this] address.

3 Click upload and find the .2sp file and flash the firmware.

4 Once finished the device will reboot.

5 Now go to [this] address and change the options for the DSL username and password. You can also change the wireless power and other bits that you don’t normally have access too.. =)

Update: I recently tried my 2 wire router with an ADSL2+ connection and it didn’t cope too well with it, so my advise is if you’re upgrading to ADSL2+, upgrade your router too.
