## Overview

This is the first half of adding a router: telling the panel which device you
mean. In scan mode the **Scan your subnet** card sweeps a CIDR range and lists
everything that answers, so you can pick a router without knowing its address.
In manual mode the **Router details** card asks for the address directly, which
is what you want when the router is on another subnet or behind a route the
scanner cannot reach.

The scan starts on its own as soon as the screen opens, using the subnet in the
**Subnet** field.

## Before you start

- For a scan, the panel needs a route to the subnet you type. A panel running
  in a bridged Docker network cannot see your LAN, so run it with host
  networking.
- For a manual entry, have the router's IPv4 address ready. The form validates
  it and will not let you continue with anything else.

## Steps

### Scanning

1. Check the **Subnet** field. It starts at `192.168.10.0/24`; change it to
   whatever range your routers live on.
2. Press **Start scan**. A progress bar reads "Scanning `<subnet>` (n%)" while
   it runs, and the results table fills in as devices are found.
3. Click a row to select that device. The panel copies its IP into the wizard,
   suggests a name from the hostname (or vendor and type), and opens the
   credentials dialog.

### Entering a target manually

1. Press **Add manually** in the page header.
2. Fill in **Display name**, the label the router gets in your list.
3. Fill in **IP address**. It must be a valid IPv4 address.
4. Fill in **Username** and **Password**.
5. Press **Connect**.

## Reference

### Scan results table

| Column | What it shows |
| ------ | ------------- |
| IP | The address that answered. |
| Hostname | Resolved host name, or empty when it does not resolve. |
| Vendor | Vendor identified from the probe. |
| Type | Device type identified from the probe. |
| Services | Services found on common ports, or empty when none answered. |

### Router details form

| Field | What it does | Default |
| ----- | ------------ | ------- |
| **Display name** | The name shown on the router card. | A generated `Nasnet <nn>` name |
| **IP address** | Address of the router. Must be valid IPv4. | `192.168.1.1` |
| **Username** | RouterOS user to connect as. | `admin` |
| **Password** | That user's password. | empty |

## Troubleshooting

**The table stays on "No devices yet. Start a scan."** Either the scan found
nothing or it could not reach the subnet. Confirm the CIDR is right and that
the panel's host is on the same network.

**Clicking a result says the router is already added.** That address is on your
list already; the dialog offers **Open router**.
