Starting with Windows 8.1, Microsoft reduced support for Adhoc Wifi networks. As a result, Windows 8.1 does not detect or display Adhoc networks in the list of available wireless networks (also known as the "wireless network picker"). Windows 10 behavior is slightly different, as it does detect and display available Adhoc networks, but when attempting to connect, it fails with a "Cannot Connect to Network" error.
This is a problem when using Windows 8.1 or Windows 10 to perform initial setup/provisioning of iTach WiFi or iTach Flex WiFi devices.
Some WiFi adapter manufacturers provide their own wireless management software with support for Adhoc networks. However, if this is not the case, a workaround procedure is described below to allow manual connection to Adhoc networks, using the Windows command shell.
Also any iOS device (iPhone, iPad, iPod), or Mac OS X device can connect to ad-hoc networks and can be used to perform the configuration of the Global Caché device.
UPDATE - 8/24/2016 - We have created a script called AdhocConnect.exe to automate this process. It is considered to be a beta release, so may not work in every scenario. It is attached at the bottom of this FAQ. Please try it out and send any feedback to firstname.lastname@example.org
Because the wireless network picker in Windows 8.1 does not show Adhoc networks, connection must be done with several manual steps.
(A text file is attached containing all required commands and instructions, allowing cut/paste of commands, and a find/replace of the <ssid> parameter).Source: http://answers.microsoft.com/en-us/windows/forum/windows8_1-networking/windows-81-ad-hoc-not-showing/5d75d887-ff59-425e-a480-9f80ada63627
From the Start Menu, find and launch "Command Prompt", or type "cmd.exe" and <ENTER> in the search box.
To see all networks in range, including Adhoc, run the following command in the command window:
> 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 wireless 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>
