- The "unsigned driver" warning doesn't seem to go away after I answer. What can I do?
Please make sure you are connected to Internet at the moment of driver installation. Windows needs to traverse the entire signature chain before properly installing the driver. Failing to do so may result in improper installation of the driver.
The signal strength you are used to observe is meant for Infrastructure Mode, when you are connected only to one point - the Access Point. And that indicator shows the signal quality between you and the AP.
In Ad-Hoc Mode, however, your station may be connected to several other stations at the same time, thus it's hard to show one indicator representing all of them.
Different manufacturers decided differently on how to report the signal strength in Ad-Hoc Mode: the smarter ones report the average value, and the cheapest ones always report a maximal signal strength no matter how weak the actual signals are.

By default, Windows 2008 installs itself without the WLAN Service. To add and enable it, please follow these steps:
- Go to Server Manager
- Add a new feature
- Select to add the Wireless LAN Service
- Finish the installation
- Install your WIFI drivers if not automatically detected.
Cancel the hardware wizard, close all open programs, start System Restore, then restore your system to the last point labeled "Before Daihinia Driver Installation".
After the system gets restored to that point and reboots, you may install the Daihinia driver again.
It's a known issue. On a HP-Compaq Notebook PC with preinstalled Windows Vista and HP software, you might get SPAPI_E_NO_DRIVER_SELECTED when trying to install Daihinia Driver.
If you try a manual installation of the driver (via adapter's property window), it will show the driver installed, but it will not work. This is because said HP software hooks to the INetCfg interface and related classes, preventing the driver to install in an official way via INetCfg (as documented and recommended by Microsoft).
Please remove the misbehaving software supplied by HP, then retry the driver installation normally via Daihinia Control App.
Feel free to contact HP on this issue, because it causes problems with any NDIS IM, not only Daihinia. This also means your antivirus or firewall might have no effect at all even if it looks like it is installed correctly.
Similar case with a Dell laptop and failing to install vmware bridge.
Daihinia is a network driver and cannot be installed without administrative privileges. Do not give such privileges to regular users and they won't violate your company's Security Policy.
The User's Guide provided in the package contains the step-by-step instructions on the Ad-Hoc network setup. Daihinia's driver activates itself when the SSID is prefixed Daihinia (example: Daihinia:Joe's-network).
If you create a public network available to anyone, name it just Daihinia and set it to be an open network with no encryption. This could be done by pressing a button in the Control Application: it will create the network on Vista and later systems and will open the User's Guide on older systems.
Actually, it goes away, but pops up again for each possible Binding Path (read: each adapter, including the virtual and disabled ones) that you have. Just answer "yes" as many times it asks.
The above said applies to XP. Vista and later are a bit smarter and ask only twice - once for each edge (upper and lower) of the driver.
If you experiment a lot with Daihinia, consider disabling the Unsigned Driver warning message.
