The Speedport W 721V shares the same features as the Speedport W 701V, adding VDSL2 support. A special feature is the FON1 passthrough, realized by a signal relay. Without electricity the FON1 port is connected to the analog POTS input to have an emergency phone.

Note that the information above is merged from all current Firmware versions available for this model, if there are multiples.
For a more detailed per Firmware view see the Firmware-Scans below, and have a look at the Firmware-History.

Daily updated index of all Speedport W 721V firmware modding projects. Last update: 2023-12-07 08:04 GMT.
This list excludes community ripping, code raping, project killing and permanent quarrel and combat enforcing individuals.
BoxMatrix tries to be a service to the community without doing harm to anyone, and not a platform to advertize the opposite.
Mother nature will bill for all time, manpower, projects, fun and passion which was ripped from the community for sick battle.
Let this reaver suck all honest work on this planet and pretend he knew it first. Mother nature will ripp it off his bones.
And if this sick (single sided) perversion continues I have no other option than invoking the police. Please someone stop him.

Daily updated scans of the latest firmware for the Speedport W 721V. Last update: 2023-12-08 05:05 GMT.
Note that models with multiple Linux instances have multiple scan results per firmware labeled main/scrpn/boot/arm/prx/atom.
All dates have been converted to GMT.
Since there is no public source for firmware the latest known archived firmware has been scanned instead.
If you could provide a more recent firmware, recovery or partition dump then please get in touch!

Daily updated index of all scanned Speedport W 721V tarballs, most of which are online. Last update: 2023-12-08 05:25 GMT.
The (main/scrpn/boot/arm/prx/atom) label in the Model column shows which CPU is meant for models with multiple Linux instances.
The Ver column shows the Firmware-Version derived from the tarball's filename, or 00.00 if not detectable.
There's no way to find this number in the source. Click the version number to get a listing of the entire tarball.
The Kern column shows the Kernel-Version from the kernel Makefile, click it to get a listing of the kernel source.
The BB column shows the BusyBox-Version from various scan sources, click it for listing the busybox addons.
The Libc and LcVer columns show the Libc-Library and its version where it could be detected, which is complicated, no listings yet.
The CC column shows the GCC-Version from its root Makefile, click it for a listing of the gcc source in the tarball.
The BR column shows the Buildroot-Version if detectable, click it for a listing of its source in the GCC tarball.
The Date column shows the date of the newest contained file. By default this list is reverse sorted by this date.
This is no perfect method, since AVM sometimes repackages older tarballs. No better method has been found so far.
