The ESP8266 Wi-Fi module can function as a Station / Client which allows other Access Points (APs) to connect to it. Station (STA) mode is useful when the module will only send / push data to another device as opposed to receiving / serving data. Prior to setting up the module as a Station, wire & configure ESP8266 module. It is also possible to configure ESP8266 module as an Access Point or both AP and STA modes simultaneously.

Prior to setting up the module for use wire & configure ESP8266 module. Besides configuring the module as an Access Point it is possible to configure ESP8266 module as a Client / Station or both modes simultaneously.
By default most Linux distributions including Arch Linux are configured with DHCP. Dynamically assigned IP is convenient for for desktop computers but quite cumbersome for headless servers. Setting up static IP allows a user defined IP addresses that will remain the same allowing to connect remotely. Arch Linux uses it’s own network configuration tool called netctl. Before you configure netctl profile you will need to find your network interface, gateway, netmask and DNS.
By default most Linux distributions including Ubuntu are configured with DHCP. This means that an IP address and some other parameters are configured automatically. The only issue with dynamic IP is that it can change making remote access a game of chance. Setting up static IP allows a user defined IP addresses that will remain the same unless changed manually.
