Arduino Network Tester, extends the functionality of the well-known Network Cable tester by adding DHCP, DNS and Internet connectivity tests using an Arduino Pro Mini and a W5500 Ethernet Shield.
When turned on, the Power LED is ON and the Status LED is blinking, until you connect an RJ45 (Ethernet Cable) from an OSI Layer 3 device (e.g. router) to the W5500 ethernet port. After that, the device runs the tests one by one starting with DHCP where it requests an IP address. If it successfully receive one then the DHCP LED lights. Next it tries to resolve the url www.example.com to the appropriate IP, if it is successful then the DNS LED lights up. Finally it makes an HTTP request to the domain www.example.com and parse the result. If the returned HTTP Status Code equals 200 then the Internet Connectivity LED turns on.
