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?
