--- comments: true --- # 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.

We’re specifically looking for [new wireless adapters](https://www.amazon.de/hz/wishlist/ls/1GA17IGQ2MF0V?ref_=wl_share) that haven’t yet been added to our system. Your donation can directly impact the scope and depth of our tests. - Join our team: Become part of our passionate and dedicated team. We’re looking for [individuals who share our vision and are eager to contribute to the development of innovative testing solutions](https://forum.armbian.com/staffapplications/). Whether you have technical expertise or simply a willingness to learn, there’s a place for you here! ## 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) ```bash 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` to avoid interface conflicts. - Add rule in `/etc/udev/rules.d/70-persistent-net.rules`: ```bash SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="xx:xx:xx:xx:xx:xx", NAME="wl" ``` ### 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/](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 ```bash #!/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="$TAILSCALE_AUTH_KEY" echo "[+] Installing iperf3 (non-interactive, no daemon)" export DEBIAN_FRONTEND=noninteractive apt-get update -qq apt-get install -yqq iperf3 echo "[βœ”] Setup complete. User '$USERNAME' added, SSH key installed, Tailscale connected." ``` ### 6. Register Your Location Access: - 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](https://netbox.armbian.com/dcim/manufacturers/61/) ???+ 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](https://github.com/armbian/armbian.github.io/actions/workflows/wireless-performance-autotest.yml) to verify whether the newly added device has been included in the test pool. ## Other resources - [USB WiFi Adapter Information for Linux](https://github.com/morrownr/USB-WiFi) - [Official Linux Wireless documentation](https://wireless.docs.kernel.org/en/latest/index.html) - [Armbian forum - Advanced users - Development](https://forum.armbian.com/forum/4-advanced-users-development/)
