How to fix Wi‑Fi hotspot not sharing internet

Step-by-step troubleshooting guide with quick checks, deeper fixes, and an FAQ.

Quick answer

Your hotspot is on, but the internet connection isn’t being routed to connected devices.

Common causes

  • Mobile data is off or weak: Hotspot needs an active cellular data connection. If data is off, in airplane mode, or the signal is too weak, the hotspot will connect but not pass data.
  • Carrier or plan blocks hotspot: Some plans disable or throttle tethering. The hotspot network appears, but data won’t flow to client devices.
  • Client device has a bad IP or DNS: A connected device can show “Connected, no internet” if it has a stale IP lease or broken DNS settings.
  • Incorrect hotspot security or band: Older devices may fail to authenticate on WPA3 or 5 GHz, connecting but not routing properly.
  • VPN or firewall interference: A VPN on the hotspot device or the client can block tethered traffic or force DNS failures.

Step-by-step fixes

  1. 1. Quick checks (do these first)

    • Confirm the hotspot device has a working internet connection by opening a website on the hotspot device itself.
    • Toggle Airplane mode on, wait 10 seconds, then off. Turn Mobile Data back on.
    • Turn Hotspot off, wait 10 seconds, then turn it back on.
    • On the client device, forget the hotspot network and reconnect using the correct password.

  2. 2. Verify mobile data and tethering are enabled

    • iOS: Settings > Cellular > Cellular Data (on). Then Settings > Personal Hotspot > Allow Others to Join (on).
    • Android: Settings > Network & internet > Internet (confirm mobile data on). Then Settings > Hotspot & tethering > Wi‑Fi hotspot (on).
    • If mobile data works on the hotspot device but tethering does not, move to the carrier plan check below.

  3. 3. Check carrier plan limits and APN profile

    • If your plan does not include hotspot, data may be blocked when tethering even though data works on the phone.
    • Check your carrier app or account page for “tethering” or “hotspot” allowance.
    • Android (only if available): Settings > Network & internet > SIMs > Access Point Names (APN). Ensure the APN matches your carrier’s current settings. Do not change values unless your carrier provides them.

  4. 4. Rebuild the hotspot connection and IP lease

    • On the client device, forget the hotspot network and reconnect from scratch.
    • Restart the client device to clear its IP lease.
    • If you can, connect a second device to test. If only one device fails, the issue is on that client.

  5. 5. Adjust hotspot security and band for compatibility

    • iOS: Settings > Personal Hotspot > Maximize Compatibility (on). This forces 2.4 GHz for older devices.
    • Android: Settings > Hotspot & tethering > Wi‑Fi hotspot > Hotspot settings. Try 2.4 GHz and WPA2‑Personal if WPA3 is enabled.
    • After changing the band or security, reconnect the client device.

  6. 6. Disable VPNs, proxies, and data saver temporarily

    • On the hotspot device, turn off any VPN and try again.
    • On the client device, disable VPN and remove any custom proxy settings.
    • Android: Settings > Network & internet > Data Saver (off for testing). iOS: Settings > Cellular > Low Data Mode (off for testing).

  7. 7. Reset network settings on the hotspot device

    • iOS: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
    • Android: Settings > System > Reset options > Reset Wi‑Fi, mobile & Bluetooth.
    • This clears saved networks and Bluetooth pairings. Re‑enable hotspot after reset.

  8. 8. Try a different sharing method to isolate the problem

    • USB tethering: Connect the phone to a computer with USB and enable USB tethering in Hotspot & tethering.
    • Bluetooth tethering: Pair the devices and enable Bluetooth tethering.
    • If USB works but Wi‑Fi hotspot fails, the issue is the hotspot Wi‑Fi configuration.

  9. 9. If you’re sharing from a computer

    • Windows: Settings > Network & internet > Mobile hotspot. Toggle Off/On. Set “Share my internet connection from” to the correct source (Wi‑Fi or Ethernet).
    • Windows: Change the network band to 2.4 GHz for older devices if available in Mobile hotspot settings.
    • macOS: System Settings > General > Sharing > Internet Sharing. Verify the correct source and Wi‑Fi options. Toggle Internet Sharing off/on.

When to worry / when to contact support

  • Hotspot worked before but now never shares internet on any device after multiple resets.
  • Mobile data is active but every tethering method (Wi‑Fi, USB, Bluetooth) fails.
  • Your carrier confirms tethering is allowed but data is still blocked.
  • The hotspot device shows mobile data outages or SIM errors even in strong coverage.

FAQ

Why does my hotspot say “Connected, no internet” on the client device?

That message usually means the client device has a bad IP or DNS lease. Forget the hotspot network, restart the client, then reconnect. If it persists, try a different device to isolate the issue.

Will turning on a VPN break hotspot sharing?

It can. A VPN on the hotspot device may not route tethered traffic correctly, and a VPN on the client can block DNS. Disable VPNs on both devices for testing.

Does hotspot require a special carrier plan?

Often yes. Many carriers treat tethering separately from regular data. If the hotspot connects but no data flows, check your plan’s tethering allowance.

Why does it work on one device but not another?

The failing client may have cached credentials, incompatible security settings, or a stuck IP lease. Forget the network, reboot the client, or switch the hotspot to 2.4 GHz WPA2.

Is there a difference between 2.4 GHz and 5 GHz for hotspots?

Yes. 5 GHz is faster but has shorter range and older devices may not support it. 2.4 GHz is more compatible and often fixes “connected but no internet” issues.
