I managed to find a solution based on your post.
Run the following .CMD script as a scheduled task.
Hope this helps someone!

@echo off
setlocal enabledelayedexpansion enableextensions
netsh wlan show interfaces|find /i /c “Infrastructure” >NUL && (
echo *** Already connected to an Infrastructure-based Wifi Network – Nothing to do.
exit /b 0
)

if [%1] == [] (
echo Usage: %~dp0 Ad-Hoc SSID
echo.
echo Fix Windows’ behavior which is to never auto-connect to an ad-hoc network.
echo With this script, the ad-hoc network is considered lower priority than predefined infrastructure-based networks
echo But if no such prefined networks are available, the ad-hoc network will be auto-connected.
echo .
exit /b 0
) else (
Set ADHOC=%1
)

REM We know we are not on an Infrastructure Wifi
REM Assume the Wifi is disconnected
Set /a onWifi=0

REM Check for an ad-hoc network
netsh wlan show interfaces | find /i /c “Adhoc” >NUL && (
Set /a onWifi=1
)

if !onWiFi! EQU 1 (
echo *** We are connected to the Ad-Hoc network.
echo *** Checking for an alternative.
for /F “delims=: tokens=2″ %%N in (‘netsh wlan show networks^|find “SSID” ‘) do @(
Set SSID=%%N
if “!SSID!” == ” ” (
REM — echo Skipping Network: !SSID!
) else (
if /i “!SSID!” == ” !ADHOC!” (
REM — echo Skipping ad-hoc !SSID!
) else (
REM — echo Found Network: !SSID!
for /F “tokens=*” %%P in (‘netsh wlan show profiles^|find “!SSID!” ^|find /i /v “!ADHOC!” ‘) do @(
Set Profile=%%N
Set Profile=!Profile:All User Profile :=!
echo *** !SSID! is available
Set ConnectNetwork=!SSID!
)
)
)
)
) else (
echo *** We are not connected to any network.
echo *** Try connecting to !ADHOC!
for /F “delims=: tokens=2″ %%A in (‘netsh wlan show networks^|find /i “!ADHOC!” ‘) do @(
Set ConnectNetwork=%%A
Set ConnectNetwork=!ConnectNetwork: =!
)
)

if “!ConnectNetwork!” == “” (
echo *** Sorry, no network could be found.
) else (
echo *** Connecting to !ConnectNetwork!
netsh wlan connect name=!ConnectNetwork! >NUL 2>NUL || (
echo Sorry, unable to connect
exit /b 0
)
)

I would also like to do something like Abdel said with watching the connectivity. Sometimes when I restart my computer (the one hosting the adhoc network and sharing internet) my wife’s computer does not disconnect from the adhoc network but instead just switches to having limited connectivity.

I’m trying to figure out if it’s possible to disconnect and reconnect if there is limited connectivity.

Thanks!

I want to code a small tool to do that .. maybe watches the connectivity –> if disconnected -> Reconnect

Thanks a lot.

unfortunately, because it also means i cannot login to my server/domaincontroller via my phone
