Fix: Multi Control app while connected to both wired and wireless network

[kilroyst]

Hi,

Multi Control is great, allowing me to use my smartphone (S25) while using the PC.

However, when docked at work, I use a wired network (Gigabit Ethernet). We also have a wireless network for guests that I can use (but limited in speed).

If I connect both my smartphone and PC to the wireless network, Multi Control works. If, after that, I connect my PC to the wired network, it still works.

HOWEVER, if I connect my PC to the wired network BEFORE activating Multi Control, it doesn't work even after connecting also to the wireless network.

I've noticed that Multi Control app ALWAYS wants to establish the connection using the connected network card with the lowest metric (i.e. highest priority). Of course, in Windows, wired networks have higher priority by default, so it will try to connect using a wired network (and fail), even if the PC is also connected to a wireless network.

You can overcome that by changing the network metrics, setting the Wi-Fi to a lower metric. However, this is a convoluted step for a normal user.

Please fix the app so that it will use the wireless network, even if the PC is connected to a wired network with higher priority.

This is the way to do it. It is sad that this is not solved in the year of 2026.

Just wanted to share a quick way to do this. I made a script with chatGPT that temporarily disconnect the ethernet connection so you can quickly disable ethernet, connect multi control, and then reenable ethernet.

The following is the main  powershell script that does it:

Samsung Multi Control.ps1

# Temporarily disable Ethernet so Samsung Multi Control can discover the Galaxy device over Wi-Fi.
# Ethernet is restored as soon as the confirmation dialog is dismissed.

$adapterName = 'Ethernet'

$identity = [Security.Principal.WindowsIdentity]::GetCurrent()
$principal = [Security.Principal.WindowsPrincipal]::new($identity)
$isAdministrator = $principal.IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)

if (-not $isAdministrator) {
$arguments = '-NoProfile -ExecutionPolicy Bypass -File "{0}"' -f $PSCommandPath
Start-Process -FilePath 'powershell.exe' -Verb RunAs -ArgumentList $arguments
exit
}

$adapter = Get-NetAdapter -Name $adapterName -ErrorAction Stop
$restoreEthernet = $adapter.Status -ne 'Disabled'

try {
if ($restoreEthernet) {
Disable-NetAdapter -Name $adapterName -Confirm:$false -ErrorAction Stop
}

Add-Type -AssemblyName PresentationFramework
[System.Windows.MessageBox]::Show(
"Ethernet is temporarily disabled. Connect Samsung Multi Control now, then click OK to restore Ethernet.",
'Samsung Multi Control',
'OK',
'Information'
) | Out-Null
}
finally {
if ($restoreEthernet) {
Enable-NetAdapter -Name $adapterName -Confirm:$false -ErrorAction SilentlyContinue
}
}

 Then we run that with powershell, or a simple cmd file.

Start multicontrol.cmd

@echo off
powershell.exe -NoProfile -ExecutionPolicy Bypass -File "%~dp0Samsung Multi Control.ps1"

Launch the cmd file, wait for the popup that says that ethernet is disabled, connect the phone and then press okay to reconnect to ethernet. I have placed these files on my desktop near the multi  control icon so it is fast to connect.

But Samsung, please fix this so  we can skip this workaround. Multi control is a great feature, and for me with mobility issues, this is a killer feature. It should just work, even with ethernet.
