Android Hotspot Not Working? How to Fix It Step by Step
A mobile hotspot is one of those features you only think about when it stops working. You turn it on, your laptop or tablet sees the network name, and then nothing connects, or it connects and there is no internet at all. It is frustrating, especially when you are away from Wi-Fi and need to get work done.
The good news is that most hotspot problems come from a small set of causes. Mobile data may be off, the hotspot settings may have changed after an update, your carrier plan may have a limit, or a power-saving feature may be quietly switching the hotspot off.
This guide starts with a quick diagnosis you can do in a couple of minutes. After that, the fixes are grouped by cause, so you can jump to the section that matches what you are seeing.
What a Mobile Hotspot Actually Does
A mobile hotspot turns your Android phone into a small wireless router. It shares your phone’s mobile data connection over Wi-Fi, so another device can get online through your phone. Some phones can also share the connection over USB or Bluetooth, but Wi-Fi hotspot is the option most people use.
That means two things have to work at the same time. First, your phone needs a working mobile data connection of its own. Second, it needs to broadcast that connection correctly to the other device.
This is why the first question to ask is not why is the hotspot broken, but where exactly does it fail? Does the other device fail to see the network name at all? Does it see the name but refuse the password? Or does it connect and then show no internet? Each answer points to a different cause, and the quick diagnosis below helps you narrow it down.
Quick Diagnosis: Find the Failure Point First
Before changing any settings, spend two minutes checking the basics. These checks take almost no effort, and they often solve the problem outright.
First, check whether your phone itself has internet. Open a browser on the phone and load a page using mobile data, with Wi-Fi turned off. If the phone cannot load anything, the hotspot cannot share a connection that is not there, and the real problem is your mobile data, not the hotspot.
Next, look at the other device. Does it see your hotspot’s network name in its Wi-Fi list? If it does not, the problem is usually on the broadcasting side: the hotspot may be off, hidden, or using a band the other device cannot see. If it does see the name, try connecting and note the exact result: a password error, a connection that drops straight away, or a connection with no internet.
Cause 1: Mobile Data Is Off, Weak, or Restricted
The most common reason a hotspot fails is also the simplest: the phone’s own data connection is not working. A hotspot can only share what the phone has.
Start by making sure mobile data is switched on. Pull down the quick settings panel and check the Mobile Data tile. It is easy to turn this off by accident, and some phones also have a separate data switch inside the mobile network settings.
Then check your signal. A weak or unstable signal can be enough for a phone to load a page slowly, but not enough to keep a hotspot connection alive for another device. If you are indoors, in a basement, or in a rural area, try moving near a window or stepping outside briefly and testing again.
Data saver settings can also interfere. Android’s Data Saver mode restricts background data use, and on some phones it can limit hotspot sharing as well. Try turning Data Saver off temporarily and testing the hotspot again.
Also check whether you have a data limit warning set on the phone. Some phones warn you or cut off mobile data when you reach a limit you set yourself in the settings.
Cause 2: Hotspot Settings Changed or Need a Refresh
If mobile data works fine on the phone but the hotspot still fails, the hotspot settings themselves are the next place to look. Updates, a new SIM, or an accidental change can alter these settings without you noticing.
Open the hotspot settings and confirm the hotspot is enabled and the network name is what you expect. If the name looks unfamiliar, another device may simply be looking for the wrong network. While you are there, check the password carefully. Passwords are case-sensitive, and a single wrong character produces a password error that looks like a deeper problem.
If the password keeps failing, change it to something simple for testing, then reconnect. Also check whether the hotspot is set to hide its network name. A hidden network will not appear in the other device’s Wi-Fi list, which can look like the hotspot is not broadcasting at all.
Another useful step is to forget the hotspot network on the other device and reconnect from scratch. Devices remember old passwords and old network details, and if any of those changed, the device may keep trying the old ones. Forgetting the network forces a clean connection attempt.
Cause 3: The Wi-Fi Band or Device Compatibility
Android hotspots can broadcast on different Wi-Fi bands, usually 2.4 GHz and 5 GHz. The band matters more than most people expect, because not every device supports both.
The 5 GHz band is faster, but it has a shorter range and older devices may not support it at all. If an older laptop or tablet cannot see your hotspot, try switching the hotspot band to 2.4 GHz in the hotspot settings. The 2.4 GHz band reaches further and works with a much wider range of devices.
The reverse can also happen. Some phones default to 2.4 GHz, and a device that expects a cleaner 5 GHz connection may struggle in a crowded area full of other 2.4 GHz networks. If you are in a busy place and the connection keeps dropping, switching bands is a quick experiment worth trying.
Cause 4: Carrier Plan Limits and Restrictions
Sometimes the phone is doing everything right, but the carrier plan does not allow the hotspot to work the way you expect. This is one of the most overlooked causes, because the hotspot switch still turns on and everything looks normal.
Some mobile plans include hotspot use, some allow it only up to a certain amount of data, and some do not include it at all. If your hotspot connects but has no internet, or works for a while and then stops, a plan limit is a real possibility. The phone itself cannot always tell you that the limit has been reached.
Your carrier’s app or account page is usually the quickest way to check. Look for your plan details and any mention of hotspot or tethering allowance. If you are unsure, contacting the carrier directly is better than guessing, because plan rules vary widely between carriers and between plans from the same carrier.
Cause 5: Battery Saver and Automatic Switch-Off
Battery saving features are designed to help, but they can quietly break a hotspot. This is especially likely if the hotspot works for a few minutes and then stops, or if it switches itself off when you are not looking.
Android’s Battery Saver mode restricts background activity and can turn off the hotspot to save power. If the problem started around the time you enabled a power-saving mode, try turning that mode off while you test. Some phones also have a separate setting that turns the hotspot off automatically when no device is connected, or after a set period of inactivity.
Check the hotspot settings for an automatic switch-off option and adjust it if needed. Also check whether your phone is in a power-saving mode at the system level, and whether any device-care or battery optimization feature is managing the hotspot or the settings app aggressively.
Cause 6: VPN, Software Glitches, and APN Settings
A VPN running on the phone can interfere with hotspot sharing. Some VPN apps route all traffic through their own tunnel, and the hotspot may not be able to share that connection with another device. If you use a VPN, try turning it off temporarily and testing the hotspot. If the hotspot works without the VPN, you have found the conflict, and you can check the VPN app’s settings for a hotspot or split-tunneling option.
Software glitches are another possibility, especially after a system update. Restarting the phone is a simple step that clears temporary problems with the network services, and it is worth doing before moving on to more involved fixes. Restart the other device as well, so both ends of the connection start fresh.
If the phone’s mobile data works but the hotspot still has no internet, the APN settings may be involved. APN stands for Access Point Name, and these settings tell the phone how to connect to the carrier’s network. They are usually set automatically when you insert a SIM, but they can occasionally be wrong or incomplete. You can find them in the mobile network settings, and your carrier can confirm the correct values. Only change APN settings if you have the correct values from the carrier, because wrong values can break mobile data entirely.
The Last Resort: Resetting Network Settings
If none of the fixes above work, resetting the network settings is the last step to try before contacting your carrier. This resets Wi-Fi, mobile data, and Bluetooth settings back to their defaults, which clears out any corrupted setting that is hard to find by hand.
Here is the warning that matters: resetting network settings deletes your saved Wi-Fi passwords. You will need to reconnect to every Wi-Fi network you normally use and enter its password again. It also removes paired Bluetooth devices, so those will need pairing again too. It does not delete your photos, apps, or files, but the Wi-Fi and Bluetooth inconvenience is real, so only use this step when the gentler fixes have not worked.
After the reset, restart the phone, set up the hotspot again with a fresh name and password, and test with one device before reconnecting everything else. If the hotspot works after the reset, you can reconnect your usual Wi-Fi networks one by one.
When to Contact Your Carrier
Some hotspot problems cannot be fixed from the phone’s settings, and knowing when to stop troubleshooting saves time. Contact your carrier if your phone has no mobile data at all despite good signal and correct settings, if the carrier’s own app shows a plan or account problem, or if the hotspot stopped working right after a plan change or SIM swap.
It is also worth contacting the carrier if the hotspot works on one SIM but not another in the same phone, or if a replacement SIM is needed. A faulty SIM can cause strange, intermittent connection problems that look like software faults.
When you contact support, it helps to describe what you have already tried: whether the phone itself has internet, whether other devices can see the hotspot name, and whether the problem is no connection or no internet after connecting.
A Calm Way to Work Through It
Hotspot problems feel urgent because they usually appear when you need a connection most. But the fix is rarely dramatic. In most cases it is a setting that changed, a limit that was reached, a power feature doing its job too well, or a plan detail that was easy to miss.
Work from the quick diagnosis outward: confirm the phone’s own data, find the exact failure point, then try the fixes grouped by cause. Change one thing at a time and test after each change, so you know which fix actually worked.

Frequently Asked Questions
Why does my hotspot turn on but have no internet?
This usually means the phone’s own mobile data is not working, or the carrier plan does not allow hotspot use. First check that the phone can load a page on mobile data with Wi-Fi off. If the phone has no internet either, fix the mobile data problem first. If the phone works but the hotspot does not, check your plan’s hotspot allowance and try turning off any VPN.
Why can’t my laptop see my Android hotspot?
The hotspot may be hidden, switched off automatically, or broadcasting on a band the laptop does not support. Check that the hotspot is on and not hidden, then try switching the band to 2.4 GHz in the hotspot settings.
Why does my hotspot keep turning itself off?
Battery saver modes and automatic switch-off settings are the usual causes. Check the hotspot settings for an auto-off option, and turn off battery saver while testing. Some phones switch the hotspot off when no device is connected for a while, which is normal behaviour rather than a fault.
Does resetting network settings delete my photos or apps?
No. Resetting network settings only resets Wi-Fi, mobile data, and Bluetooth settings. It does not delete photos, apps, or files. However, it does delete saved Wi-Fi passwords and paired Bluetooth devices, so you will need to reconnect to your usual networks and pair your devices again afterwards.
Can a VPN stop my hotspot from working?
Yes, a VPN can interfere with hotspot sharing on some phones, because it routes traffic through its own tunnel. Try turning the VPN off temporarily and testing the hotspot. If the hotspot works without the VPN, check the VPN app’s settings for a hotspot or split-tunneling option.
Should I contact my carrier or the phone maker first?
Start with the carrier if the phone has no mobile data at all, if your plan details mention a hotspot limit, or if the problem began after a plan or SIM change. Contact the phone maker if mobile data works fine but the hotspot feature itself seems broken, especially after a software update that may have introduced a bug.
