You're watching Netflix, on a work call, or about to submit something important—then you notice your router's red light blinking. Your internet is down, and panic sets in. Don't worry. This guide will get you back online fast.
Power cycle your router and modem – this works 60% of the time:
Unplug both router AND modem
Wait 30 seconds (important!)
Plug in modem first, wait for steady lights
Plug in router, wait 2-3 minutes
If the red light turns green, you're done. If not, keep reading.
Unplug your router and modem from power. Wait a full 30 seconds—this clears the temporary memory. Plug in the modem first and wait for solid lights. Then plug in the router and give it 2-3 minutes to fully boot up.
Loose or damaged cables cause more problems than you'd think. Check:
Coaxial cable going into your modem
Ethernet cable between modem and router
All power connections
Wiggle each cable. If the light changes, you found your problem.
Feel your router. If it's hot to the touch:
Move it away from walls and other electronics
Clean dust from the vents
Remove anything stacked on top
Let it cool for 15 minutes before trying again
Before troubleshooting further, check if your internet provider has an outage:
Visit DownDetector.com on your phone's cellular data
Check your ISP's Twitter/X account
Call your provider's automated line
Outdated firmware causes connection issues. Access your router's admin page (usually 192.168.1.1 or 192.168.0.1), find the firmware section, and check for updates.
If nothing else works:
Find the reset button (small hole on back)
Hold for 10-15 seconds with a paperclip
Wait for router to fully reboot
Reconfigure your WiFi network name and password
A blinking red light means your router can't establish an internet connection. Common causes:
Temporary glitches – Memory issues from running too long
ISP outages – Your provider's service is down
Cable problems – Loose or damaged connections
Overheating – Dust buildup or poor ventilation
Firmware bugs – Outdated software causing conflicts
Hardware failure – Router reaching end of life (3-5 years typical)
