Check router and internet

When several devices are offline

Read the complete step before making changes. Stop if unsure or if new warnings appear.

Tell others before restarting
Restarting a router interrupts internet access and often internet phone calls, smart-home connections and transfers. Tell others first. Do not press Reset: a factory reset can erase connection, phone and Wi-Fi settings.
Check 1: Test two devices
Test two devices. If only one fails, investigate that device instead of resetting the router.
Check 2: Check power and connection cables
Check power and connection cables. Look up the Internet/DSL/WAN light in the manual for your exact model.
Check 3: Use mobile data to check your provider for an outage
Use mobile data to check your provider for an outage. Note when it started and the status lights.
Check 4: If no update is running, use the router restart function or disconnect power for 30 seconds
If no update is running, use the router restart function or disconnect power for 30 seconds. Allow up to 10 minutes to reconnect. Do not press Reset; contact the provider if the fault continues.
