As anyone who owns one of these routers knows, the default administration interface is very limited, many features that this router supports have been locked out by sky (DNS settings, Quality of Service, IP Filtering etc.). The default sky firmware actually has a secondary Sagem web interface with access to all these settings, but it is turned off by default (and it cannot be changed from the sky web interface).

This custom firmware updates the configuration area of the router to allow access to this advanced web interface.

Warnings: Read these carefully!

• If your router gets unplugged / there is a power cut during the upgrade process your router may become inoperable. However unlikely this may seem, it is a very real possibility and this procedure should only be attempted if you have a backup router.
• All your router settings will be lost during the upgrade process, INCLUDING the factory default settings (wireless SSID, wireless key and MAC address). If somthing has happened to the sticker on the base of your router detailing this information DO NOT flash this firmware. Without these details you will not be able to connect to the internet.
• It is highly recommended that you connect to your router directly via ethernet cable and NOT through wireless while updating.
• It is highly recommended that your disconnect your router from the phone line while updating.
• All though I have tested this firmware extensively, there is a chance that something may go wrong. I will not be held responsible for any harm that comes to your router due to use of this firmware.
• Sky automatic updates have not been disabled by default, if they release a firmware or configuration update in the future it may overwrite this firmware and disable the extra features.

Advantages

• The full sagem web interface is enabled by default, giving access to a large amount of previously unavailable settings.
• This firmware will work with Sky Router Tool.
• Contains a 'lite' version of Sky Router Tool which runs on the router.

How to install it

• Before continuing make sure you read, and understand all of the warnings above
• Download the new firmware from FAST2504N_6.14.2a4N_mrmt32_v1.w
• Log into the sky web interface and select "Maintenance" followed by "Router Upgrade"
• Browse for the firmware file then click "Upload". Make sure you do not unplug your router after starting the upgrade process, doing so could permanently break it.
• Wait about 2 minutes before trying the next step.
• After 2 minuites visit http://192.168.0.1 (if you previously had changed your router's ip address it will now have reverted to the default).
• If all went well you should be greeted by the following screen:

• Type in the details it asks for, making sure they exactly match those on the bottom of your router
• After clicking save you should get the following screen and your router will reboot:

Sagem Web Admin Access

Sky Auto Update

The sky automatic firmware update is still enabled with this firmware. If Sky release a firmware update, it may overwrite this modified firmware.

This is the original, now unsupported version of Sky Router Tool. It only supports the DG834GT but has a Windows Forms interface instead of the new web interface.

You can download it from here.

Disabling Sky Auto Update

The sky automatic firmware update can be disabled by visiting http://192.168.0.1/skyinfo.html, clearing the fields marked "FVC file URL 1", "FVC file URL 2" and "Default HTTP POST URL" and clicking save. Note that doing this may allow sky to know that you are using custom firmware (as your router will no longer access their servers checking for updates).

Re-Enabling Sky Auto Update

Follow the disabling procedure but fill in the following settings:
FVC file URL 1: http://fast2504.skyfirmware.com
FVC file URL 2: http://fast2504.skyfirmware.com
Default HTTP POST URL: http://fast2504.skyfirmware.com/status/
