Internet No Internet Access / Not Secured / Not Available: Complete Fix Guide (Windows 10, Android, LG TV & T-Mobile Home Internet)

Understanding the Error

When your device shows 'Internet No Internet Access', 'No Internet Secured', or 'Internet Not Available' it means the Wi-Fi or Ethernet link layer is working (your device can talk to the router) but Layer 3 (IP routing to the public internet) is broken. Windows 10 detects this via the Network Connectivity Status Indicator (NCSI) probe — it tries to reach http://www.msftconnecttest.com/connecttest.txt. If that fails, the yellow triangle appears. Android uses a similar captive portal check (connectivitycheck.gstatic.com). LG Smart TVs use a proprietary check.

Exact error strings you may see:

• Internet no internet access (Windows 10 taskbar tooltip)
• No Internet, Secured (Windows 10 Wi-Fi flyout)
• Internet not available (Android Wi-Fi settings)
• Connected but no internet (generic router UI)
• Unable to connect to the internet (LG Smart TV)
• 169.254.x.x IP address (Windows APIPA — DHCP failed)
• DNS_PROBE_FINISHED_NO_INTERNET (Chrome browser)
• ERR_INTERNET_DISCONNECTED (Chrome browser)

Step 1: Diagnose the Scope

First, determine whether the issue is device-specific or network-wide.

Test 1 — Check all devices: If every device (phone, laptop, TV) on the same Wi-Fi shows no internet, the problem is your router, modem, or ISP. If only one device is affected, the problem is on that device.

Test 2 — Ping the gateway (Windows): Open Command Prompt as Administrator and run:

ipconfig

Note your Default Gateway (usually 192.168.1.1 or 192.168.0.1). Then:

ping 192.168.1.1

• If ping succeeds → router is reachable, issue is DNS or upstream routing.
• If ping fails → DHCP/IP layer broken; proceed to IP renewal steps.

Test 3 — Ping public IP (bypass DNS):

ping 8.8.8.8

• If this succeeds but websites fail → DNS is the culprit.
• If this fails → routing or ISP issue.

Test 4 — Check IP address class: An IP starting with 169.254 means DHCP failed and Windows assigned itself an Automatic Private IP Address (APIPA). This is almost always the cause of 'No Internet Access' when no other device is affected.

Step 2: Fix on Windows 10

Fix 2a — Release, Renew, and Flush DNS

Open Command Prompt as Administrator:

ipconfig /release
ipconfig /flushdns
ipconfig /renew

Wait 30 seconds. Check the taskbar — if the yellow triangle disappears, you're done.

Fix 2b — Reset Winsock and TCP/IP Stack

If 2a did not work:

netsh winsock reset
netsh int ip reset resetlog.txt
netsh int ipv4 reset
netsh int ipv6 reset

Reboot the computer. This rebuilds the Windows network stack from scratch.

Fix 2c — Set Static DNS

If you can ping 8.8.8.8 but not domain names:

1. Open Settings → Network & Internet → Change adapter options.
2. Right-click your Wi-Fi or Ethernet adapter → Properties.
3. Select Internet Protocol Version 4 (TCP/IPv4) → Properties.
4. Choose Use the following DNS server addresses:
   • Preferred: 8.8.8.8
   • Alternate: 1.1.1.1
5. Click OK. Test connectivity.

Fix 2d — Disable IPv6

Some routers advertise IPv6 but cannot route it, causing 'No Internet Secured':

1. Adapter Properties → uncheck Internet Protocol Version 6 (TCP/IPv6).
2. Click OK and wait 10 seconds.

Fix 2e — Run Windows Network Diagnostics & Reset

msdt.exe /id NetworkDiagnosticsNetworkAdapter

Alternatively, Settings → Network & Internet → Status → Network Reset (re-installs all adapters — requires reboot).

Fix 2f — Update or Roll Back Network Adapter Driver

1. Press Win+X → Device Manager.
2. Expand Network Adapters.
3. Right-click your Wi-Fi adapter → Update driver or Properties → Driver → Roll Back Driver.

Step 3: Fix on Android ('Internet Not Available on Wi-Fi')

Android marks a Wi-Fi network with 'Internet not available' when its captive portal check to connectivitycheck.gstatic.com fails.

Fix 3a — Forget and Reconnect:

1. Go to Settings → Wi-Fi.
2. Long-press your network → Forget.
3. Reconnect and re-enter the password.

Fix 3b — Set Static IP with Manual DNS:

1. Tap the gear icon next to your Wi-Fi network.
2. Tap Advanced → change IP settings from DHCP to Static.
3. Set DNS 1 to 8.8.8.8 and DNS 2 to 1.1.1.1.
4. Save and reconnect.

Fix 3c — Reset Network Settings (Android): Settings → General Management → Reset → Reset Network Settings. This resets all Wi-Fi passwords, Bluetooth pairings, and APN settings.

Step 4: Fix on LG Smart TV ('Internet Not Working')

LG Smart TVs running webOS frequently show 'Unable to connect to the internet' when DNS servers provided by the router are unreachable from the TV's DNS client.

Fix 4a — LG TV DNS Change:

1. Settings → All Settings → Network → Wi-Fi Connection (or Wired).
2. Choose your network → Advanced Wi-Fi Settings → Edit.
3. Turn Set Automatically OFF for DNS.
4. Enter 8.8.8.8 as DNS Server.
5. Connect.

Fix 4b — LG TV Network Reset: Settings → All Settings → General → Reset to Initial Settings (or Support → Self Diagnosis → Reset). Note: This resets all app logins.

Fix 4c — Update LG TV Firmware: Settings → All Settings → Support → Software Update → Check for Updates. Many 'LG TV internet not connecting' reports on forums are resolved by a firmware update.

Step 5: Fix T-Mobile Home Internet 'No Internet'

T-Mobile Home Internet gateways (Nokia, Arcadyan, Sagemcom) sometimes maintain a 4G/5G signal (bars show on the gateway) but lose upstream IP routing. All devices on the network show no internet.

Fix 5a — Reboot via T-Mobile App:

1. Open the T-Mobile Home Internet app.
2. Tap Restart Gateway.
3. Wait 3–5 minutes for full reconnection.

Fix 5b — Manual Power Cycle:

1. Unplug the gateway for 60 seconds.
2. Plug back in and wait for the light to turn solid (green or white).

Fix 5c — Check for Upload Speed = 0: If internet no upload speed is the symptom (download works, upload is 0 Mbps), this typically indicates a T-Mobile network congestion or beam-forming issue. Move the gateway to a window facing a cell tower, or call T-Mobile support to reprovision the SIM.

Fix 5d — Change DNS on T-Mobile Gateway:

1. Open browser → go to 192.168.12.1.
2. Log in (default: admin/admin or check sticker).
3. Navigate to LAN Settings → DNS → enter 8.8.8.8 / 8.8.4.4.
4. Save and reboot gateway.

Step 6: Router-Level Fixes (All Platforms)

If multiple devices are affected:

1. Power cycle modem and router separately — unplug modem, wait 30 sec, plug in, wait for sync light, then plug in router.
2. Check ISP status page — visit your ISP's outage map or status Twitter account before spending an hour troubleshooting.
3. Factory reset router — hold reset button 10–30 seconds. Reconfigure Wi-Fi SSID and password. Use 8.8.8.8 as DNS in router WAN/DNS settings.
