Connecting multiple Wi-Fi networks using a terminal box

To connect multiple Wi-Fi networks simultaneously on a Linux terminal, you typically need multiple wireless interfaces, each configured separately using command-line tools like nmcli, iwctl, or wpa_cli.Hardware RequirementsTo connect to more than one Wi-Fi network at the same time, your system generally requires multiple Wi-Fi adapters. A single adapter can sometimes create virtual interfaces, but support depends on the driver and hardware capabilities, and it may not work reliably for simultaneous connections . Each adapter or virtual interface acts as a separate network interface (e.g., wlan0, wlan1).Using Command-Line Tools1. nmcli (NetworkManager CLI)List available interfaces: nmcli device statusScan for networks: nmcli device wifi listConnect to a network: nmcli device wifi connect password ifname Save profiles for automatic reconnection: nmcli connection add type wifi ifname con-name ssid Repeat these steps for each interface to connect to different networks .2. wpa_cliLaunch interactive session for a specific interface: wpa_cli -i Add a new network: add_networkSet SSID and password: set_network ssid "" and set_network psk ""Enable the network: enable_network Save configuration: save_configExit: quit Repeat for each Wi-Fi interface to connect to separate networks .3. iwctl (iwd client)Start interactive session: iwctlList devices: device listScan for networks: station scanConnect: station connect This method is lightweight and suitable for headless systems .Virtual Interfaces (Optional)Some Wi-Fi adapters support virtual interfaces, allowing a single physical adapter to connect to multiple networks. You can check support using iw list and create virtual interfaces with iw dev wlan0 interface add wlan1 type station. However, not all drivers support this, and performance may be limited .VerificationCheck connection status: nmcli connection show or ip addr showTest connectivity: ping or ping google.comBest PracticesEnsure each interface has a unique IP configuration to avoid conflicts.Save configurations to persist across reboots.Use secure permissions for configuration files, especially when using wpa_supplicant.Keep your system updated to maintain compatibility with network drivers and tools . By following these steps, you can manage multiple Wi-Fi connections on a terminal box, either for bonding, redundancy, or accessing separate networks simultaneously.
