[Solved] USB tethering w/ multiple android clients  

Hi @thierry-beccaro,

This is probably has something to do with the Network adapter priority of your windows primary machine.

On Windows 10, if you have a device with more than one network adapter (such as Ethernet and Wi-Fi), (in your case you have 2 Remote NDIS network adapter for the 2 USB tethering connection, right?), each interface receives a priority value automatically based on its network metric, which defines the primary connection that your device will use to send and receive networking traffic.
reference: https://www.windowscentral.com/how-change-priority-order-network-adapters-windows-10

Maybe you can try to manually set the metric value of the other Remote NDIS network adapter with lower value than the other one so that you don't have to disable-enable it.
Please check the reference link I posted above for the steps on how to set it.

Hi Lea,

Indeed this is working when I change the metrics, but the problem becomes inverse as I now have to enable/disable usb tethering on the other tablet.

Not sure why this is happening but I came out with a powershell script that roll out metrics priority through my devices. Credits go to that guy : <a href=" removed link "> removed link

There is the script in case anyone's facing the same issue :

$INTERFACES=wmic nic get NetConnectionID

$INTERFACES|%{ 
if ($_ -like 'ags2-w09*') 
{ 
$N=$_.trim() 
$ExParm='netsh interface ip set interface interface="'+"$N"+'" metric = 20' 
Write-Host $ExParm 
Invoke-Expression $ExParm 
} 
elseif ($_ -like 'me572c*') 
{ 
$N=$_.trim() 
$ExParm='netsh interface ip set interface interface="'+"$N"+'" metric = 10' 
Write-Host $ExParm 
Invoke-Expression $ExParm 
} 
}

$INTERFACES|%{ 
if ($_ -like 'ags2-w09*') 
{ 
$N=$_.trim() 
$ExParm='netsh interface ip set interface interface="'+"$N"+'" metric = 10' 
Write-Host $ExParm 
Invoke-Expression $ExParm 
} 
elseif ($_ -like 'me572c*') 
{ 
$N=$_.trim() 
$ExParm='netsh interface ip set interface interface="'+"$N"+'" metric = 20' 
Write-Host $ExParm 
Invoke-Expression $ExParm 
} 
} 
Write-Host ' ' 
Write-Host ---------------------------- New Connection Metic ---------------------------- 
Write-Host ' ' 

Get-WmiObject -Class Win32_NetworkAdapter -Filter "AdapterType like '%802.3'" | 
%{ 
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter "Index=$($_.DeviceId)" | Select-Object Description,IPConnectionMetric 
}

Where me572c and ags2-w09 are my interfaces names, to be changed to yours.
It can easily be adapted to more devices, the idea is just that each device must be prioritized once.

Also, this has to be run as admin.

Thanks a lot!
