This firmware is intended for UK use only.

This ZIP contains two versions of the firmware. They are identical except that
the .RST version also contains factory default settings for the router, so using
that version will clear (wipe) out all of your existing router settings, back
to the factory default state.

To upgrade your firmware, use the Firmware Upgrade Utility which is
supplied on CD-ROM with your router, or can be downloaded.
