How to Fix Android Hotspot Not Working: The Ultimate Troubleshooting Guide

We’ve all been there: you’re in a coffee shop or on a train, your laptop is ready for action, but your phone’s mobile hotspot is acting like a stubborn mule. It’s frustrating, especially when you have deadlines looming and your phone shows a full 5G signal.

If your Android hotspot is not working, it could be anything from a simple setting oversight to a complex network configuration issue. Before you consider throwing your device out the window, follow this comprehensive guide to get your tethering back on track.

1. Start with the “Universal Reset”

It sounds like a cliché, but restarting your device is the first step for a reason. Modern smartphones are complex computers that occasionally experience “hiccups” in their background processes.

Restart your phone: This clears the temporary cache and restarts the network radio.
Restart the receiving device: Sometimes the issue isn’t your phone—it’s the laptop, tablet, or car head unit trying to connect.

2. Check Your Mobile Data Connection

It seems obvious, but you’d be surprised how often this is the culprit. A hotspot is simply a bridge for your mobile data. If the bridge has no water under it, no one is crossing.

Verify Data: Open a browser on your phone and try to load a website. If it doesn’t load, your hotspot won’t work either.
Data Limits: Many carriers have a “Hotspot Data Cap” that is separate from your phone’s main data. Check your carrier app to see if you’ve hit your monthly tethering limit.

3. Disable Battery Saver & Data Saver Modes

Android is designed to be efficient. When your battery gets low or you enable Data Saver, the system identifies the hotspot as a “luxury” and shuts it down to preserve resources.

How to fix it:

Go to Settings > Battery. Turn off Battery Saver.
Go to Settings > Network & Internet. Look for Data Saver and ensure it is Off.
Some phones have a “Power Saving” mode specifically for hotspots in the hotspot settings menu—make sure “Turn off hotspot automatically” is disabled if you want a persistent connection.

4. Toggle Airplane Mode

This is a “soft reset” for your phone’s antennas. By toggling Airplane Mode on and then off, you force the phone to re-authenticate its connection with the cell tower.

Swipe down the notification shade.
Tap the Airplane icon.
Wait 10 seconds.
Tap it again to turn it off.

5. Change the WiFi Band (2.4 GHz vs. 5 GHz)

Most modern Android phones support both 2.4 GHz and 5 GHz bands.

5 GHz is faster but has a much shorter range and struggles with interference (walls, furniture).
2.4 GHz is slower but more compatible with older devices and has a better range.

If the receiving device can’t even see your hotspot, it’s likely because it doesn’t support 5 GHz. Switch your hotspot settings to 2.4 GHz to maximize compatibility.

6. Update Your APN Settings

The Access Point Name (APN) is the “address” your phone uses to connect to your carrier’s internet. Sometimes, the default APN doesn’t allow tethering.

To check APN:

Go to Settings > Network & Internet > SIMs.
Select your SIM and tap Access Point Names.
Tap the current APN.
Find APN Type. Ensure it includes default,supl,dun. (Note: Be careful here; some carriers restrict “dun”—which stands for dial-up networking—so only edit this if you know your carrier allows it).

7. Check Security Settings (WPA3 vs. WPA2)

Android 12 and higher often default to WPA3 security. While it’s more secure, many older laptops and tablets cannot communicate with WPA3.

Go to your Hotspot Settings.
Look for Security.
Change it from WPA3-Personal to WPA2-Personal.
Pro Tip: As a last resort, try “None” (Open) just to see if it connects. If it does, you know the security protocol was the issue. (Just don’t leave it open for long!).

8. Clear the System Cache or Reset Network Settings

If you’ve tried the above and still see “Android hotspot not working,” it’s time to get a bit more aggressive. Resetting your network settings will revert all WiFi, Bluetooth, and Mobile Data configurations to their factory defaults.

Warning: This will delete your saved WiFi passwords and paired Bluetooth devices!

How to do it:

Go to Settings > System > Reset options.
Tap Reset WiFi, mobile & Bluetooth.
Confirm and restart your phone.

9. Check for “Max Connection” Limits

In the hotspot configuration menu, there is often a setting called “Manage Allowed Devices” or “Max Connections.”

If this is set to “1” and you are trying to connect a second device, it will fail silently. Make sure this limit is set high enough to accommodate all your devices. Similarly, check your Blocked List to ensure you didn’t accidentally blacklist your own laptop!

10. Carrier Restrictions and System Updates

Sometimes, the problem isn’t technical—it’s contractual.

Carrier Subscription: Some budget plans explicitly block tethering. If your hotspot turns on but provides “No Internet,” your carrier might be blocking the data flow at their end.
Software Updates: Manufacturers often release “Network Stability” patches. Go to Settings > System Update and make sure you are running the latest version of Android.

Conclusion

When your Android hotspot is not working, it is usually a conflict between power-saving features or a mismatch in the WiFi band. By systematically checking your data connection, disabling savers, and adjusting your band frequency, you can usually solve 99% of tethering issues.

If you’ve reset your network settings and checked with your carrier, and it still won’t work, there may be a hardware issue with your phone’s WiFi antenna. But in most cases, a quick toggle of the WPA settings or a frequency shift will have you back online in no time.
