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 and 10 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.
Windows 10 will detect the Adhoc network, but attempting to connect will return with a "Cannot Connect to Network" error message.
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.
There is a text file attached with all commands and instructions included that will allow an easy find and replace function to replace the <ssid> for each line within the text editor.
Because the wireless network picker in Windows 8.1 doesn't show adhoc networks, connecting must be done by hand.Source: http://answers.microsoft.com/en-us/windows/forum/windows8_1-network...
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. Replace <ssid> with the SSID of your network for all following commands:> netsh wlan set profileparameter <ssid> connectiontype=ibss
For Windows 10, the command is:> netsh wlan set profileparameter <ssid> connectiontype=ibss connectionmode=manual
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>

This process applies to all GC RS232 available device: GC-100-xx/iTach WF2SL or IP2SL/Flex with Flex Link Serial cable.
The simplest test to determine whether the transmit and receive of the RS232 serial port is described below:
A successful response will confirm that the serial connection is functioning.
If the response is unsuccessful, then double-check the settings and the loop, and try again.
If there continues to be issues, contact email@example.com for further assistance.
Brian Kerth September 15, 2015 • iTach / iTach FAQ's
How do I perform a factory reset on my iTach? This applies to all models of the iTach - IP2IR, WF2IR, IP2SL, WF2SL, IP2CC, and WF2CC.
A factory reset on an iTach will default all settings to the original factory state. This is useful in several cases:
1) For Wifi (WF2XX) units, this will put the unit into Adhoc mode. Adhoc is the initial configuration state that is necessary to connect to the device via a direct Wifi connection, with a default IP of 169.254.1.70. Once connected with a compatible device, the iTach can be configured for a local SSID via DHCP or Static IP addressing. Once the configuration has been changed to Infrastructure, and the network settings have been entered and saved, it will leave Adhoc network and attempt to connect to the entered network.
2) For Wired/Ethernet (IP2XX) units, this will place the unit back into default mode, which automatically enables DHCP. When the unit is connected via ethernet to a router, it will pull an IP address from the router DHCP server. Once the IP address is known, either via iHelp or a network monitoring tool, the user can navigate to the web page by typing the IP address into a web browser.
3) If ENABLE LOCK has been checked on the unit, configuration changes cannot be made. Resetting the unit to default will allow a new configuration.
4) If AUTHENTICATION has been enabled, the unit will require a username and password to access configuration. If that password is not known, a reset will default the device, removing the authentication requirement.
To perform a factory reset, you will need a small metal pin, such as a paperclip.
-With the unit powered ON, gently insert the metal pin in the small metal hole located just to the bottom and right of the power cord input of the iTach.
-It is NOT a button.
-You will need to touch the two metal lead that are just inside the hole. If you do not make contact at first, wiggle the metal pin around just a bit until contact is made.
-Once contact has been made, the iTach LED's will turn off, and then back on, blinking briefly. This indicates that reset has been completed and you may remove the pin.
-Note: The reset hole also contains the learning diode for IR Learning. If you push the metal pin in too far, you may damage the unit, voiding your warranty
Attached is a demonstration video of a reset on an iTach IP2IR.
