Hi Mikkel,
We have found many users complaining about the ad hoc networks not being shown in the wireless network list in Windows 8.1.
As a work around, I would suggest you to use the Wireless hosted network and check if that helps you connect both the computers.
- In the Search Charms, type command prompt, right click on command prompt and select Run as Administrator.
- Type the following commands and press enter. netsh wlan show drivers
note: Check the "Hosted network supported" string. If it is yes, then your wireless network adapter supports hosted network feature. If not, then you will not be able to use it.
If the string is yes, then follow these steps and check.
To setup a hosted network,
netsh wlan set hostednetwork mode=allow ssid=”DESIRED_NETWORK_NAME” key=”YOUR_PASSWORD”
To Start the Hosted network,
netsh.exe wlan start hostednetworkname When you are finished with it, you can stop the connection using this command:netsh.exe wlan stop hostednetworkname You can get detailed information about the network you started with this command:netsh wlan show hostednetworkname You may even download third party to connect two computers wirelessly.Disclaimer: Using Third Party Software, including hardware drivers can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the use of Third Party Software can be solved. Using Third Party Software is at your own risk. Hope this information is helpful. If you have any concerns, let us know.
