What platforms are supported?

Posted in

Currently, Windows XP, Vista, 7, Server 2008 are supported.

There is ongoing development for Linux (Ubuntu family). Due to huge architectural differences of Windows and Linux, it is written from scratch, only some algorithmical calculations could be ported. It takes a lot of effort...

What is the situation on Windows 8/8.1?

Posted in

We received only one user feedback that it worked on 8.1.

We couldn't reproduce the working condition in our lab, so these Windows versions remain officially unsupported. You can try your luck yourself, there is little to lose except maybe several minutes.

Daihinia on Windows 10?

Posted in

When trying to install the driver on Windows 10, the following error message may appear:

Why doesn't Daihinia ...?

Maybe that's what you'll do when you grow up? :)

On the more serious side, it is intended to be simple. It doesn't mean you cannot do whatever you have on your mind, but that might require advanced knowledge, a thing that we do not want to require from the majority of users.

Just keep in mind that a Daihinia mesh is seen as one Ethernet segment, and you can combine it with many other software you might want (traffic shapers/accounters, captive portals and so on).

v1.8.8 released!

Posted in
  • When displaying system errors, we now also specify which API was called; troubleshooting is easier when the context of the error is known in addition to the error code.

v1.8.7 released!

Posted in
  • We now load DIFxAPI dynamically: from the system if the system has it (newer systems) or from Daihinia package if the system doesn't have it (older systems).
    By doing so, we eliminate the hassle for older systems (XP, Server 2008) users to manually add DIFxAPI.DLL to System32, while permitting Microsoft to fix their library on newer systems (Windows 8.1, 10) without our intervention, via their system updates.
    "Middle-aged" systems like Windows 7 work normally, as usual.
  • (possible bug fix) We now explicitly remove the Miniport part of the driver package upon uninstallation. Reportedly, on some systems, the miniport part remained in the system after Daihinia uninstallation. Hopefully this will fix the issue.

v1.8.6 released!

Posted in
  • (bugfix) License status might have got lost on some systems with multiple user accounts.

Multimedia/Gaming setting in the adapter properties, should I enable it?

Posted in

Some adapters may have a Multimedia/Gaming Environment setting in their properties, as per the picture below.

Some notes on 802.11h

Posted in

802.11h is an extension that allows dynamic frequency usage of the 5GHz spectrum.

The story is that in the 802.11n mode the 2.4GHz spectrum is still used for beaconing and control messages, while the 5GHz spectrum is used for data transmission, so the 2.4GHz band is offloaded.

Enabling 802.11h allows stations to dynamically change the data frequency band, which helps in case of interference with neighboring nodes, resulting in a smoother distribution of traffic across the mesh.

Support of this feature varies from adapter to adapter. Newer adapters use 802.11h by default and it is implicitly enabled with no setting. Moderately old adapters have a setting in the adapter properties, so you have to enable it manually. Old adapters may not have 802.11h at all, but updating their drivers might help bring it, because their drivers usually contain wifi chip microcode, which might also have got updated with a newer driver release.
