Compare device names/MAC addresses with your equipment, disconnect questionable devices if the router permits, and change Wi-Fi credentials if unauthorized access is suspected.
Step by Step
- Determine whether the problem affects one device or every device on the network.
- Compare device names/MAC addresses with your equipment, disconnect questionable devices if the router permits, and change Wi-Fi credentials if unauthorized access is suspected.
- Change one setting or component at a time and test again.
- Record existing router/network settings before changing passwords, DNS, addressing, or advanced configuration.
If That Doesn't Work
- Router menus, indicator lights, and terminology vary by manufacturer and internet provider.
- Avoid factory-resetting a modem/router unless you know how it is provisioned and have the information needed to restore the connection.
