Testing the speed of wireless adapters

All wireless adapters were tested under consistent conditions - each positioned in close proximity (1-2m) and connected to the same wireless access point (AP). The adapters utilized various interface types, including USB, SDIO, and PCI, to evaluate performance across different hardware configurations.

Test Equipment

Access Point: Zyxel NWA130BE (Wi-Fi 7)
Network Switches:
- Netgear XS712T
- Netgear XS508M
Power Switches: APC AP7920
Client Devices:
- Multiple single-board computers equipped with onboard wireless modules or PCI Wi-Fi cards
- USB wireless test server: Geekom IT13 with an i-Tec 16-port USB 3.0 hub

Software and Infrastructure

Infrastructure Database: NetBox for resource modeling and inventory
Automation: GitHub Actions for workflow orchestration and test execution
Networking: Tailscale for secure device connectivity across the test environment
Test Platform: KVM virtual machine running the latest x86 Armbian image for USB wireless testing

Methodology

Overview of the WiFi performance test process:

⚡ Power On Devices
└─ Embedded WiFi-capable devices and USB wireless adapters are powered on.
🌐 Configure Wireless Connection
└─ Devices are configured to connect to a predefined access point (SSID).
📶 Connect to WiFi Network
└─ Network connectivity is validated to ensure the device is routable.
📊 Measure Performance (iperf3)
├─ Perform reverse (-R) and forward iperf3 tests
└─ Measure throughput and link quality.
🔍 Collect System & Network Info
├─ Extract link details (e.g. bitrate, signal strength)
└─ Record system version, kernel, architecture.
🔁 Restore Wired Network
└─ Reapply original routes and configuration.
☁️ Upload Test Results
└─ Summary, logs, and system info are uploaded as artifacts.
📴 Power Off Devices
└─ All test devices are safely powered down after testing completes.

Adding a New Device

This guide provides step-by-step instructions to add a new device (SBC SDIO, PCI or USB adapter) to the wireless testing infrastructure.

1. Prepare the Host Machine

Ensure the board and wireless device is supported by Armbian.
Flash Armbian image and configure basic settings
Set hostname that reflects wireless test device (eg. rtl3070, wifiserver)

sudo hostnamectl set-hostname rtl3070

2. Identify Network Interfaces

Use ip link or iw dev to list available interfaces.
Identify MAC address and interface name (e.g., wlan0, wlxMAC, etc.).

3. Create a UDEV Rule

!!! warning

This step is only necessary if your network device does not have a predictable interface name.

Use a predictable name like wl<MAC> to avoid interface conflicts.
Add rule in /etc/udev/rules.d/70-persistent-net.rules:

SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="xx:xx:xx:xx:xx:xx", NAME="wl<MAC>"

4. Get VPN access

The TAILSCALE_AUTH_KEY and access credentials for NetBox must be provided by the Armbian administration team. For assistance, please contact us via https://www.armbian.com/contact/.

5. Prepare the machine

Creates a new user (ci) with sudo privileges
Configures SSH for key-based authentication only
Installs and configures Tailscale for secure remote access
Installs iperf3 for network performance testing

#!/bin/bash

set -e

USERNAME="ci"
KEY_URL="https://github.armbian.com/ci.asc"
TAILSCALE_AUTH_KEY="tskey-auth-kXXXXXXXXXXXXXXX-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"

echo "[+] Creating user '$USERNAME' without password"
useradd -m -s /bin/bash "$USERNAME"
passwd -d "$USERNAME"
usermod -aG sudo "$USERNAME"

echo "[+] Setting up SSH key from $KEY_URL"
SSH_DIR="/home/$USERNAME/.ssh"
mkdir -p "$SSH_DIR"
curl -fsSL "$KEY_URL" -o "$SSH_DIR/authorized_keys"
chmod 700 "$SSH_DIR"
chmod 600 "$SSH_DIR/authorized_keys"
chown -R "$USERNAME:$USERNAME" "$SSH_DIR"

echo "[+] Disabling password authentication in SSH config"
sed -i 's/^#*\s*PasswordAuthentication.*/PasswordAuthentication no/' /etc/ssh/sshd_config
sed -i 's/^#*\s*PermitEmptyPasswords.*/PermitEmptyPasswords no/' /etc/ssh/sshd_config
systemctl restart ssh

echo "[+] Installing Tailscale"
curl -fsSL https://tailscale.com/install.sh | sh

echo "[+] Bringing up Tailscale with provided auth key"
tailscale up --auth-key="$TAILSCALE_AUTH_KEY"

echo "[+] Installing iperf3 (non-interactive, no daemon)"
export DEBIAN_FRONTEND=noninteractive
apt-get update -qq
apt-get install -yqq iperf3

echo "[✔] Setup complete. User '$USERNAME' added, SSH key installed, Tailscale connected."

6. Register Your Location

Access: https://stuff.armbian.com/netbox/dcim/sites/

Sites in NetBox represent physical locations of wireless test equipment.
Each site have devices such as Access Points (APs), iperf3 servers, and wireless test clients.
Register your testing location first if it doesn't exist yet. Create a new site with a clear name (e.g., Office Berlin, Lab Maribor) and add necessary data.

!!! warning Make sure to check if site is not already define to not clutter database!

???+ success "Update Relevant Information"

- Access point SSID: `Your SSID`
- Iperf3 server IP: your local `IP address` that runs iperf3 server and can be accessible from wireless client

7. Register Device Type

Add new device type

???+ success "Relevant data"

- Model name (CAPS): AIC8800
- Manufacturer: Generic
- Add image of the device in full HD (1920x1080) with exact same name as model AIC8800.png (CAPS name, lowercase extension)

!!! warning

Skip this step if WiFi SoC already exists in database.

8. Register Device

???+ success "Relevant data"

- Name: Compex WLE900VX (use commercial name)
- Device role: WiFi DUT
- Tags: USB Wireless
- Manufacturer: Generic
- Device type: AIC8800 (select the one you added previously)
- Serial number: 04:f0:21:2c:75:14 (MAC address)
- Location: where you are
- Site: name of your office, defined in previous step
- Custom Fields / class: AC (wifi classes: AX, AC, N)

Add virtual interface (Add Components -> Interfaces)

???+ success "Relevant data"

- Name: `tailscale0`
- Type: `virtual`

Then select interface tailscale0 and add IP address. Copy IP address from your device (example: 100.115.0.58/32) and select: Make this the primary IP for the device/VM

9. Run Initial Test

Run the Wireless Performance Autotest workflow to verify whether the newly added device has been included in the test pool.
