# IP Range Conflicts

The MVP warns you when your Wi-Fi and Ethernet connections share the same IP subnet. This page explains why it matters and how to fix it.

***

## What Is the Problem?

When both Wi-Fi and Ethernet are connected and share the same network subnet, the operating system can't reliably determine which network interface to use to communicate with the MVP. This specifically affects **ArtNet output.**  The ArtNet broadcast may be routed incorrectly.

***

## How Conflict Detection Works

The MVP compares the **network ranges** of both interfaces. If they overlap, a conflict exists.

For example:

* **Ethernet**: 192.168.1.111 / 255.255.255.0 → network 192.168.1.0
* **Wi-Fi**: 192.168.1.50 / 255.255.255.0 → network 192.168.1.0
* **Result**: Same network address → **Conflict detected**

The conflict warning appears **only** when **all** of these conditions are true:

1. Ethernet **is connected** (cable plugged in)
2. Ethernet is in **Static** mode
3. Wi-Fi **is connected**
4. Both interfaces have valid IP and subnet values
5. The computed network addresses are **equal**

The warning does **not** appear when:

* Only one interface is connected
* Ethernet is in DHCP mode
* The interfaces are on different subnets (e.g., Wi-Fi on 192.168.1.x, Ethernet on 2.0.0.x)

***

## How the Warning Is Displayed

When a conflict is detected, an **"IP Range Warning"** button appears in the Ethernet dialog with an information icon.

Clicking the warning button opens a secondary dialog titled **"ArtNET IP Range Warning"** that explains:

* ArtNet/DMX users should take action; others can safely ignore the warning
* "Your Ethernet and Wi-Fi connections are both on the same IP range/subnet, which can prevent ArtNET playback from working properly."

The dialog then presents recommended solutions.

## How to Fix It

### Use the Standard ArtNet Range (Recommended)

Set the Ethernet to the standard Art-Net IP range, which doesn't conflict with typical Wi-Fi networks:

| Field           | Value           |
| --------------- | --------------- |
| **IP Address**  | 2.0.0.111       |
| **Subnet Mask** | 255.0.0.0       |
| **Gateway**     | *(leave blank)* |

This is the recommended approach for ArtNet operation. The 2.x.x.x range is the traditional Art-Net standard and is extremely unlikely to conflict with any Wi-Fi network.
