operation FAQ

Questions concerning the modes of usage and some operational details, useful for practitioners.

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.

How many adapters do I need?

Posted in

One WiFi adapter per computer. Extra adapters are needed only on the gateway computers between your Daihinia mesh and other networks (if any).

Do we need a homegroup for Daihinia?

Posted in

Depends on the purpose of your Daihinia mesh.

If you feel that a homegroup would simplify your life, then create it. Homegroups require IPv6, Daihinia is perfectly compatible with IPv6, so there are no problems.

What is WiFi Ad-Hoc Mode in principle?

Posted in

When you connect to an Access Point, your computer communicates only with the Access Point. Even if you send data to another computer in the same WiFi network, data travels to the AP first, then the AP repeats it in the air for the target machine. That mode is called Infrastructure Mode. All participants in the network should be in the range of the AP, and the whole network fails if the AP goes wrong.

On the other hand, there is Ad-Hoc Mode (also called IBSS), when all computers in that network are peers with equal rights, and send data directly to each other. Daihinia adds smartness to this mode by relaying packets from one computer to another computer by using a computer in the middle, in those cases when such a relaying is needed, i.e. when the first two computers are out of range for each other. Doing so multiple times results in a mesh of computers, which appears as one single network segment to all participants.

What to consider when buying an adapter?

Posted in

The best meshing experience is with adapters that have good signal power and sensitivity, and a good implementation of the 802.11 Ad-Hoc (technically called IBSS) mode. Please note that in IBSS mode your adapter must maintain connections with all neighboring nodes (while in Infrastructure mode it always communicates only with the AP), so, your adapter's chip must be powerful enough to handle that load.

Also please note that adapter range depends not on the adapter alone, but in pairs with other adapters it has a link with. Combination of one's power and another's sensitivity. We offer a 30-day trial so you can test in your particular case.

We have a poll where you can vote for the WiFi chipsets that your adapters have, so we can keep an eye on the most widespread chipsets and test them in our lab. Please visit and vote.

Is Daihinia ready for IPv6?

Posted in

Yes, Daihinia is ready for IPv6. Tested and confirmed to work.

By design, Daihinia mesh is compatible with any protocol that can be carried in Ethernet frames, including exotic/proprietary protocols. As long as the drivers of such protocols are well-behaving and query the underlying layer for the maximum packet size (and not blindly assume 1500), they should all work correctly.

What type of network to tell when Win7/Vista asks upon connection?

Posted in

It is strongly recommended to choose Public if your Daihinia mesh is open and unencrypted at the WiFi level.

You may choose one of the other two options (Home or Workplace) only when your mesh is encrypted and you have strong confidence that the security credentials were not compromised (stolen, leaked, or cracked). Otherwise it's better to choose Public too.

Note: to enable file sharing from your computer, the network type has to be Home or Workplace, depending on what files you plan to share.
