# ip-settings.ps1 — LAN Network Profile Configurator

A PowerShell script for quickly switching a Windows network adapter between predefined static IP profiles or DHCP. Designed for situations where you need to connect to devices on different subnets — such as cameras, PLCs, or other industrial equipment — without manually digging through Network Settings every time.

---

## Features

- Auto-detects all physical network adapters and shows their current status, mode (DHCP/Static), and IP address
- Lets you pick the adapter interactively by number
- Applies one of two pre-configured static IP profiles or switches back to DHCP
- Verifies and displays the new IP after applying

---

## Requirements

- Windows 10 / Windows 11
- PowerShell 5.1 or newer (pre-installed on all modern Windows systems)
- **Administrator privileges** (required to change network settings)

---

## First-Time Setup

If you have never run a local PowerShell script before, you may need to allow script execution once:

```powershell
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
```

---

## How to Run

**Option A — Right-click**
Right-click `ip-settings.ps1` → **Run with PowerShell**
> Note: this may not run as Administrator. If the script exits with an admin warning, use Option B.

**Option B — Administrator PowerShell (recommended)**
```powershell
# Open PowerShell as Administrator, navigate to the script folder
cd C:\Users\Dejan
.\ip-settings.ps1
```

## Usage Walkthrough

### Step 1 — Select your adapter

The script lists all physical network adapters found on the system:

```
  Available Network Adapters:

  [1]  Ethernet                            Status: Up            Mode: DHCP      IP: 192.168.1.100
  [2]  Ethernet 2                          Status: Disconnected  Mode: Static    IP: 192.168.178.22

  Enter adapter number: 1
```

### Step 2 — Choose a profile

```
  Profiles:
  [1]  Camera Control  ->  192.168.178.22  /24   GW: 192.168.178.1
  [2]  LAN Profile 2   ->  192.168.1.222   /24   GW: 192.168.1.1
  [3]  DHCP (automatic)

  Enter profile number: 1
```

### Step 3 — Done

The script applies the settings and confirms the new IP:

```
  [OK]  Camera Control applied -> 192.168.178.22/24  GW: 192.168.178.1
  [..]  Verifying new config...

  Current IP : 192.168.178.22/24
```

## IP Profiles

| Profile | IP Address | Subnet Mask | Gateway | Use Case |
|---|---|---|---|---|
| **Camera Control** | 192.168.178.22 | 255.255.255.0 (/24) | 192.168.178.1 | Camera / device control network |
| **LAN Profile 2** | 192.168.1.222 | 255.255.255.0 (/24) | 192.168.1.1 | Local area network |
| **DHCP** | Automatic | Automatic | Automatic | Standard office / home network |

---

## Customizing Profiles

To change the IP addresses, subnet, or gateway — open `ip-settings.ps1` in any text editor and find these lines:

```powershell
# Profile 1 - Camera Control
$newIP = "192.168.178.22"; $prefix = 24; $gateway = "192.168.178.1"

# Profile 2 - LAN Profile 2
$newIP = "192.168.1.222"; $prefix = 24; $gateway = "192.168.1.1"
```

Edit the values and save. No other changes needed.

## Troubleshooting

**"Please run this script as Administrator!"**
Open PowerShell by right-clicking the Start button → **Terminal (Admin)** or **Windows PowerShell (Admin)**.

**"running scripts is disabled on this system"**
Run this once in PowerShell:
```powershell
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
```

**No adapters listed**
Make sure at least one physical (non-virtual) network adapter is present and visible in Device Manager.

**IP not applied after DHCP switch**
DHCP can take a few seconds. Wait a moment and check with:
```powershell
ipconfig /all
```
