Chrome Connectivity Diagnostics is a fast and simple network testing and troubleshooting tool for Chrome and Chrome OS.

The tool tests a computer's network connection for common issues, port blocking, and network latency by establishing connections to network and Internet services via UDP, TCP, HTTP and HTTPS.

The diagnostic tests include:​

• • Local network connection availability
  • Wifi network signal strength (Chrome OS only)
  • Default gateway is reachable (Chrome OS only)
  • DNS server availability and latency
  • DNS cache poisoning/spoofing
  • Internet traffic blocks by a HTTP captive portal or firewalls
  • Network performance and latency to Google websites
  • Google Hangouts service availability
