FAQ: Windows 8.1 and Windows 10 AdHoc network support solution

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.

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 support@globalcache.com


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).

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


SETUP

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

***NOTE***

For Windows 10, the command is:

> netsh wlan set profileparameter <ssid> connectiontype=ibss connectionmode=manual


CONNECT

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.


DISCONNECT

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

> netsh wlan disconnect


CLEANUP

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

> netsh wlan delete profile <ssid>

An additional note on Adhoc. There have been reported issues with the need to enable Adhoc mode within the Wireless Adapter drivers for the PC.
Go to Device Manager-->Network Adapters--><your wireless adapter>-->Advanced.
There may be a setting for Adhoc mode available. If attempting to connect to Adhoc with an iTach that uses 802.11b, do not have 802.11n Adhoc mode enabled.  Please let us know other examples that you find within the driver settings by commenting on this post.
***Microsoft Surface devices do not support Adhoc in the embedded wireless chipset in use.**

 

There is also another utility available that does not require the command line solution that is outlined above.

 

Download the Wi-Fi Scanner found here: http://lizardsystems.com/wi-fi-scanner/.

 

After running, the iTach or Flex may show up in the list of broadcasting devices. Right-click on it and select "Connect". If it is successful, try opening a browser and entering the default IP of the iTach (169.254.1.70) or Flex (192.168.1.70). If the device has connected, the web configuration page will appear, and you can proceed with configuring the device to connect to the local SSID.

 

It may be necessary to Disconnect the device with the Wi-Fi Scanner after completing the configuration.

    Tried adding a WF2IR manually per above and connecting via Lizard Systems.  Neither works.  The only way I can connect to this module is with a Win7 PC.  What else can I try?

    Steve,

    There may be an additional configuration on the Network Adapter Card that allows you to "Enable Adhoc" or something similar. If this doesn't work, contact support@globalcache.com and we can troubleshoot further.

    Using Windows 10 on another computer and the procedure described above worked - both computers using same version of Windows - the difference is network adapter for when it didn't work is Intel dual band Wireless AC7265.  Adapter that did work is "<no name> 802.11 Wireless LAN card"

    If you have a Microsoft Surface Pro, Adhoc is not supported in the Marvell Wireless chipset. You will not be able to use a Surface Pro to connect via Adhoc.

    I'm very happy to found this ... Struggled wit gaining access to a TP-LINK w-lan printserver ...

    I tried lot of different things with "netsh wlan" settings but coud not make it under windows10.

    Due to your precise and detailed explanation it works.

    FYI: during my several trial and errors I have also set the Qualcom Atheros AR9485 profile > AdHoc 11n = Enable

    Thank you!

    This method worked for me smoothly, Though I failed to connect when I had WEP security ON on my Nokia E5 (the ad hock WiFi hot-spot). With open WiFi it worked perfectly. I want to say thank you very much. I am running on Win 10 64 bit. All in all it's working.

    You can easily create a wireless adhoc network in Windows 8 and 10 using this simple application -> http://www.easyaslinux.com/tutorials/wireless-ad-hoc-network-windows-8-10/

    We followed ALL examples given here.  We also turned on the AdHoc feature in the wifi hardware driver.  No errors displayed.  The iTech device still does not display in the Edge or Internet Explorer Browser.  This machine is Windows 10 Creator Update.  Please advise.
