<h1 id="wi-fi-wireless-lan">Wi-Fi (Wireless LAN)<a class="headerlink" href="#wi-fi-wireless-lan" title="Permanent link"></a></h1>
<p>Infix includes comprehensive Wi-Fi support for both client (Station) and
Access Point modes. When a compatible Wi-Fi adapter is detected, the system
automatically creates a WiFi radio (PHY) in factory-config, that can
host virtual interfaces.</p>
<h2 id="architecture-overview">Architecture Overview<a class="headerlink" href="#architecture-overview" title="Permanent link"></a></h2>
<p>Infix uses a two-layer WiFi architecture:</p>
<ol>
<li>
<p><strong>WiFi Radio (PHY layer)</strong>: Represents the physical wireless hardware</p>
<ul>
<li>Configured via <code>ietf-hardware</code> module</li>
<li>Controls channel, transmit power, regulatory domain</li>
<li>One radio can host multiple virtual interfaces</li>
</ul>
</li>
<li>
<p><strong>WiFi Interface (Network layer)</strong>: Virtual interface on a radio</p>
<ul>
<li>Configured via <code>infix-interfaces</code> module</li>
<li>Can operate in Station (client) or Access Point mode</li>
<li>Each interface references a parent radio</li>
</ul>
</li>
</ol>
<h2 id="naming-conventions">Naming Conventions<a class="headerlink" href="#naming-conventions" title="Permanent link"></a></h2>
<p>Like other interface types in Infix, WiFi components follow naming conventions
that allow the CLI to automatically infer types:</p>
<table>
<thead>
<tr>
<th><strong>Name Pattern</strong></th>
<th><strong>Type</strong></th>
<th><strong>Description</strong></th>
</tr>
</thead>
<tbody>
<tr>
<td><code>radioN</code></td>
<td>WiFi Radio</td>
<td>Hardware component for WiFi PHY</td>
</tr>
<tr>
<td><code>wifiN</code></td>
<td>WiFi Interface</td>
<td>Virtual WiFi interface on a radio</td>
</tr>
</tbody>
</table>
<p>Where <code>N</code> is a number (0, 1, 2, ...).</p>
<div class="admonition tip">
<p class="admonition-title">Tip</p>
<p>Using these naming conventions simplifies configuration since type/class
settings are automatically inferred. For example, creating a hardware
component named <code>radio0</code> automatically sets its class to <code>wifi</code>, enabling
the <code>wifi-radio</code> configuration container.</p>
<p><strong>Note:</strong> This inference only works with the CLI. Configuring WiFi over
NETCONF or RESTCONF requires setting the class/type explicitly.</p>
</div>
<h2 id="current-limitations">Current Limitations<a class="headerlink" href="#current-limitations" title="Permanent link"></a></h2>
<ul>
<li>USB hotplug is not supported - adapters must be present at boot</li>
<li>Interface naming may be inconsistent with multiple USB Wi-Fi adapters</li>
<li>AP and Station modes cannot be mixed on the same radio</li>
</ul>
<h2 id="supported-wi-fi-adapters">Supported Wi-Fi Adapters<a class="headerlink" href="#supported-wi-fi-adapters" title="Permanent link"></a></h2>
<p>Wi-Fi support is primarily tested with Realtek chipset-based adapters.</p>
<h3 id="known-working-chipsets">Known Working Chipsets<a class="headerlink" href="#known-working-chipsets" title="Permanent link"></a></h3>
<ul>
<li>Built-in Wi-Fi on Banana Pi BPi-R3</li>
<li>Built-in Wi-Fi on Raspberry Pi 4/CM4</li>
<li>Realtek:<ul>
<li>RTL8188CU</li>
<li>RTL8188FU</li>
<li>RTL8821CU</li>
</ul>
</li>
</ul>
<p>Other Realtek chipsets may work but are not tested.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>Some Realtek chipsets require proprietary drivers not included in the
standard kernel.</p>
<ul>
<li>Firmware requirements vary by chipset</li>
<li>Check kernel logs if your adapter is not detected</li>
</ul>
</div>
<h3 id="usb-wifi-dongles">USB WiFi Dongles<a class="headerlink" href="#usb-wifi-dongles" title="Permanent link"></a></h3>
<p>USB WiFi dongles may be slow to initialize at boot due to firmware
loading. If your USB dongle is not detected reliably, configure a
<code>probe-timeout</code> on the radio to wait for the PHY:</p>
<pre class="cli"><code>admin@example:/&gt; <b>configure</b>
admin@example:/config/&gt; <b>edit hardware component radio0 wifi-radio</b>
admin@example:/config/hardware/component/radio0/wifi-radio/&gt; <b>set probe-timeout 30</b>
admin@example:/config/hardware/component/radio0/wifi-radio/&gt; <b>leave</b>
</code></pre>
<p>This waits up to 30 seconds for the radio PHY to appear before creating
WiFi interfaces. If the PHY is not detected within the timeout, a dummy
interface is created as a placeholder, allowing IP configuration to proceed.
Reboot when the radio becomes available.</p>
<h2 id="radio-configuration">Radio Configuration<a class="headerlink" href="#radio-configuration" title="Permanent link"></a></h2>
<p>Before configuring WiFi interfaces, you must first configure the WiFi radio.
Radios are automatically discovered and named <code>radio0</code>, <code>radio1</code>, etc.</p>

<h2 id="discovering-available-networks">Discovering Available Networks<a class="headerlink" href="#discovering-available-networks" title="Permanent link"></a></h2>
<p>Before connecting to a WiFi network, you need to discover which networks
are available. Infix automatically scans for networks when a WiFi interface
is created with a radio reference.</p>
<h3 id="enable-background-scanning">Enable Background Scanning<a class="headerlink" href="#enable-background-scanning" title="Permanent link"></a></h3>
<p>To enable scanning without connecting, configure the radio and create a WiFi
interface referencing it:</p>
<p><strong>Step 1: Configure the radio</strong></p>
<pre class="cli"><code>admin@example:/&gt; <b>configure</b>
admin@example:/config/&gt; <b>edit hardware component radio0 wifi-radio</b>
admin@example:/config/hardware/component/radio0/wifi-radio/&gt; <b>set country-code DE</b>
admin@example:/config/hardware/component/radio0/wifi-radio/&gt; <b>leave</b>
</code></pre>
<p><strong>Step 2: Create WiFi interface with radio reference only</strong></p>
<pre class="cli"><code>admin@example:/&gt; <b>configure</b>
admin@example:/config/&gt; <b>edit interface wifi0</b>
admin@example:/config/interface/wifi0/&gt; <b>set wifi radio radio0</b>
admin@example:/config/interface/wifi0/&gt; <b>leave</b>
</code></pre>
<p>The system will now start scanning in the background. The interface will
operate in scan-only mode until you configure a specific mode (station or
access-point).</p>
<h3 id="view-available-networks">View Available Networks<a class="headerlink" href="#view-available-networks" title="Permanent link"></a></h3>
<p>Use <code>show interface</code> to see discovered networks and their signal strength:</p>

<h2 id="passphrase-requirements">Passphrase Requirements<a class="headerlink" href="#passphrase-requirements" title="Permanent link"></a></h2>
<p>To ensure your connection is secure and compatible with all network
hardware, your passphrase must meet the following criteria:</p>
<ul>
<li>Length: Between 8 and 63 characters</li>
<li>Characters: Use only standard English keyboard characters<ul>
<li>Allowed: Letters (A-Z, a-z), numbers (0-9), and common symbols (e.g., ! @ # $ % ^ &amp; * ( ) _ + - = [ ] { } | ; : ' " , . &lt; &gt; / ? ~)</li>
<li>Spaces: Spaces are allowed, but not at the very beginning or very end of the passphrase</li>
<li>Prohibited: Emojis, accented characters (like á or ñ), and special "control" characters</li>
</ul>
</li>
</ul>
<div class="admonition tip">
<p class="admonition-title">Why the limit?</p>
<p>Standard WiFi security (WPA2/WPA3) requires a minimum of 8 characters to
prevent "brute-force" hacking. The character limit ensures your password
works on older routers and various operating systems.<br>

<div class="admonition tip">
<p class="admonition-title">Important</p>
<p><strong>MAC Address Requirement for Multi-SSID:</strong>
When creating multiple AP interfaces on the same radio, you <strong>must</strong> configure
a unique MAC address for each secondary interface (wifi1, wifi2, etc.) using
<code>set custom-phys-address static &lt;MAC&gt;</code>. All interfaces on the same radio inherit
the radio's hardware MAC address by default, which causes network conflicts. Only
the primary interface (alphabetically first, e.g., wifi0) should use the default
hardware MAC address.</p>
<p>Choose MAC addresses from the same locally-administered range:</p>
<ul>
<li>Primary (wifi0): Uses hardware MAC (e.g., <code>00:0c:43:26:60:00</code>)</li>
<li>Secondary (wifi1): <code>00:0c:43:26:60:01</code> (increment last octet)</li>
<li>Tertiary (wifi2): <code>00:0c:43:26:60:02</code> (increment last octet)</li>
</ul>
</div>
<p><strong>Result:</strong> Three SSIDs broadcasting simultaneously on radio0:</p>
<ul>
<li><code>MainNetwork</code> (WPA3, most secure)</li>
<li><code>GuestNetwork</code> (WPA2/WPA3 mixed mode)</li>
<li><code>IoT-Devices</code> (WPA2 for compatibility)</li>
</ul>
<p>All APs on the same radio share the same channel and physical layer settings
(configured at the radio level). Each AP can have its own:</p>
<ul>
<li>SSID (network name)</li>
<li>Security mode and passphrase</li>
<li>Hidden/visible SSID setting</li>
<li>Bridge membership</li>
</ul>
<p>You can verify the configuration with <code>show hardware component radio0</code> to see
radio settings, and <code>show interface</code> to see all active AP interfaces.</p>
<div class="admonition tip">

"good" or "excellent" signal in scan results</li>
<li><strong>Check credentials</strong>: Use <code>show keystore symmetric &lt;name&gt;</code> to verify
the passphrase matches the network password</li>
<li><strong>Review logs</strong>: Check system logs with <code>show log</code> for Wi-Fi related
errors</li>
<li><strong>Regulatory compliance</strong>: Ensure the country-code on the radio
matches your location</li>
<li><strong>Hardware detection</strong>: Confirm the WiFi radio appears in <code>show
hardware</code></li>
</ol>
<p>If issues persist, check the system log for specific error messages that
