A free Android smartphone tool (Routercheck) analyses the safety of your router.
Is your Wi-Fi router hacker bait? By Preston Gralla
Your router can have plenty of vulnerabilities. Your password may be insecure. You may be using a too-weak encryption standard. It may have open ports through which hackers can slither. Services that may be dangerous, such as Universal Plug and Play (uPnP), may be turned on.
The free Android app Router Check looks for all that and more. It also checks your router make and model to see whether it’s known to have vulnerabilities. It analyzes your DNS configuration to see if it’s reliable and trustworthy. It even checks to see whether hackers have tampered with your router.
