Spectrum Internet Connected But Not Working

First, isolate the layer

1. Try loading a website by IP address in your browser: `http://1.1.1.1` — if this loads, your DNS is the problem. Change your device's DNS to 1.1.1.1 or 8.8.8.8.
2. If IP address also fails, try a wired connection. If wired works, your router is the issue.
3. If wired also fails, the modem or Spectrum's network is the issue. Check the modem's online light.

The five most common causes

DNS server issue — Spectrum's DNS occasionally has hiccups. Fix: change device DNS to Cloudflare (1.1.1.1) or Google (8.8.8.8).

IPv6 misconfiguration — some Spectrum routers hand out broken IPv6. Fix: disable IPv6 on the device or router as a test.

DHCP lease expired — the router thinks you have an IP but Spectrum doesn't recognize it. Fix: reboot modem then router.

Router has an IP but no gateway — device says 'no internet' immediately. Fix: forget the network and rejoin.

Captive portal on public Wi-Fi mistakenly saved — device tries to auth against a portal that doesn't exist on your home network. Fix: forget the network.

When it's just one device

If only one device says 'connected, no internet' and other devices work fine, the device's Wi-Fi driver or IP config is stuck. Forget the network, restart the device, rejoin. Fixes 95% of one-device cases.
