Spectrum provides a separate modem and router to most subscribers. When your internet stops working, the problem could be either device. This guide helps you identify which one is at fault and fix it.
Step 1: Check the Modem First
The modem connects to Spectrum's network. Check its Online LED. If it's solid blue/green, the modem is fine and the problem is the router. If it's blinking or red, the modem can't reach Spectrum — fix the modem first before touching the router.
Step 2: Power Cycle Both
- Unplug both modem and router
- Wait 60 seconds
- Plug in modem first — wait 3-5 minutes (Online LED solid)
- Plug in router — wait 2-3 minutes (light solid blue)
- Test internet on your device
Step 3: Check Spectrum Outage
Use your phone: open My Spectrum app → check for outage alerts. Visit downdetector.com/status/spectrum. If there's an outage, nothing to do but wait.
Step 4: Check Cables
- Coax cable: Wall → Modem (tight on both ends)
- Ethernet cable: Modem → Router WAN port
- Try different cables
- Bypass coax splitter if present
Step 5: Test Direct Modem Connection
Connect a computer directly to the Spectrum modem via Ethernet. If you get internet, the router is the problem. If not, the modem or Spectrum service is the issue. This test is critical for efficient troubleshooting.
Step 6: Change DNS
Sometimes you're "connected" but pages won't load — DNS failure. On your device: set DNS to 8.8.8.8 and 8.8.4.4. Windows: Settings → Network → WiFi adapter → Edit DNS → Manual → 8.8.8.8. Mac: System Preferences → Network → DNS → add 8.8.8.8.
Step 7: Factory Reset Router
Hold reset button for 10 seconds. Reconfigure WiFi via My Spectrum app or 192.168.1.1. This fixes corrupted settings.
Step 8: Contact Spectrum
Call 1-833-267-6094. Ask them to: send a refresh signal, check your signal levels, reprovision equipment, or schedule a technician. Have your account number ready.
Frequently Asked Questions
Why is my Spectrum router not connecting to the internet?

Unplug BOTH modem and router. Wait 60 seconds. Plug in modem first — wait 3-5 minutes for Online LED to be solid. Then plug in router — wait 2-3 minutes for solid blue light. Test internet. This resolves most connectivity issues.
Spectrum WiFi connected but no internet — how to fix?
You're connected to the router but not reaching the internet. Fix: (1) Restart modem and router (modem first), (2) Try a different device — if all devices fail, it's the router/modem, (3) Try Ethernet directly to modem — if that works, router issue, (4) Change DNS to 8.8.8.8 on your device, (5) Call Spectrum.
How do I access Spectrum router settings?
Open a browser → type 192.168.1.1. Default credentials are on the label on the Spectrum router. You can also manage WiFi settings through the My Spectrum app (easier). Note: Spectrum limits some advanced settings on their provided routers.
Can I use my own router with Spectrum?
Yes — you still need Spectrum's modem (or an approved modem from their list), but you can use any router. Plug your router's WAN port into the Spectrum modem via Ethernet. Set connection type to DHCP. Your own router will give better performance and more features.
