The Billion BiPAC 5200G routers that we supply are affected by a
problem that manifests itself when used on the same network as a
Windows XP machine running Service Pack 3.

There is a list of the affected firmware versions and a link to
download the updated firmware here:

If you have a BiPAC 5200G router, please upgrade the firmware, or
contact support, who should be able to perform the upgrade for you.

Please note that this only affects the wireless "G" variants of the
Billion routers that we supply; not the single port or four port
models.

If you have any questions, please contact support.
