How can I troubleshoot my wireless internet / network / system?

There are several possible issues that can be checked:

  • Is internet service working (check with your internet provider)?
  • Is the wireless router working (powered on, ports working)?
  • Is the system within a reasonable distance of the wireless router?
  • Is software configured correctly? (network settings in OS, sw, drivers, router, wireless band [a/b/g/n/ac], passphrase)?
  • Is the wireless card properly connected and working?
  • Is your antenna properly connected (internal or external)?
  • Is the motherboard working properly?
