A lot of variables are involved when you connect to a network: cables, network adapters, drivers, and routers. So troubleshooting network connection problems can be challenging. This article can help you find and fix problems with wired (Ethernet) and wireless (Wi‑Fi) network connections. Some common problems are:

A wireless network adapter switch is turned off

Airplane mode is turned on

Disconnected or improperly connected cables

Incorrect WEP, WPA, or WPA2 security keys or passphrases

Mismatched wireless standards

Missing updates

Incorrect network connection settings

Damaged or incompatible drivers

Hardware or software problems

Follow the steps in these sections to try to solve the problem, and then try connecting after each one. If the problem still occurs, move on to the next section.

Use an automated troubleshooter

An automated troubleshooter can find and automatically fix some common networking problems. Run the Network troubleshooter first, and then test your network or Internet connection to see if the problem has been fixed. If it doesn't fix the problem, try the rest of the automated troubleshooters.
