It has come to our attention that Microsoft made a breaking change in Windows 8.1, and removed Adhoc support from any screens that display the available wireless networks.  Windows 8.1 can still connect to Adhoc networks, but this cannot be accomplished through the normal methods.

This can be a problem for Windows 8.1 users when attempting to perform initial setup of iTach or iTach Flex wireless devices.

Some manufacturers of WiFi adapters provide their own connection software, which may offer support for Adhoc networks.  However, if this is not the case, there is a method to manually connect to Adhoc networks, which requires using the Windows command shell.

Because the wireless network picker in Windows 8.1 doesn't show adhoc networks, connecting must be done by hand.

To see all networks in range, including Adhoc, run the following command in command shell (cmd.exe):

> netsh wlan show networks


The following must be done once for each network:

  • Go to "Network and Sharing Center"
  • Click "Set up a new connection or network"
  • Double click "Manually connect to a wireless network"
  • Enter the SSID of the adhoc network (as shown by "netsh wlan show networks") into the "Network name" field
  • Configure security settings accordingly
  • Uncheck "Start this connection automatically" (important)
  • Click "Next", then "Close"

Run the following command (important):

> netsh wlan set profileparameter <ssid> connectiontype=ibss

Replace <ssid> with the SSID of your network.


After setting up, run the following command whenever you want to connect:

> netsh wlan connect <ssid>

Replace <ssid> with the SSID of your network.

Hovering over the WiFi icon in the system tray will show the name of the network you are currently connected to, even if it's an adhoc network (the network picker will not show it if it's adhoc). The name is also visible in "Network and Sharing Center" window.


To disconnect from the adhoc network connect to a different network, turn off WiFi, or run the following command:

> netsh wlan disconnect


To remove the network profile from Windows, run the following command:

> netsh wlan delete profile <ssid>

Replace <ssid> with the SSID of your network.

We've released new versions of our iLearn, iTest, and iConvert utility software:

iLearn 2.7 fixes the issues seen in versions 2.5 and 2.6, where attempting to learn codes could result in unpredictable or lost results.  The interface has also been restructured.

iConvert 3.3 introduces the ability to convert to and from GC Compressed format codes, as well as the GC and Hex formats it has previously supported

iTest 1.3 has been cleaned up a bit, but is generally functionally unchanged.

All of these are now built on Microsoft .Net 4.0, upgraded from .Net 2.0.  On some systems, you may need to update .Net, as a result.


For more details, see the full release notes:  iLearn release notesiConvert release notesiTest release notes.

Recently, an issue arose which caused a group of iTach WiFi units (primarily the WF2IR) to get stuck in their initial boot and continuously reboot. This is characterized by the unit flashing all LEDs as it initially boots, waiting a moment, then flashing all LEDs again repetitively (delay, flash sequence, delay, flash sequence etc). The cause of this problem was an isolated batch of a wireless related part, which has been fully filtered from our production process for some time and is no longer a continuing issue. If you have one of these units or have gotten one in the past, we apologize for any inconvenience this caused you. If you see your unit present this symptom, send a message to us with an explanation that you are getting the continuous reboot, as well as your shipping information, to and we will swap out your unit for a fresh one from our facilities.
