How do I troubleshoot an IP?

Try typing in “ipconfig /release” followed by “ipconfig /renew” to get rid of your current IP address and request a new one. This will in some cases solve the problem. If you still can’t get a valid IP from your router, try plugging your computer straight into the modem using an ethernet cable.
