Firmware Upgrade CD v1.00/1.01

About the CD
The cd is bootable, and will allow you to upgrade the firmware in your router The cd was primarily designed to help people that are running Windows 2000/XP and using NTFS partitions. (It will also work if you are using FAT/FAT32 or Linux partitions).

The settings in this firmware are for uk routers, if you are not from the uk then please use the values from the router configuration settings page, here you will find the values for (VPI/VCI/Protocol/Encapsulation). I cannot be certain that all these values are correct, but if you know otherwise then please send me a message via the contact form

Also It is known that the conexant flash program will not work with SIS, nForce2 & KT266 chipsets. Intel chipsets have been reported to work fine. I have made a list of some of error messages that can occur with the Conexant flash program. They can be found here
