Not all internet issues arise from the service provider, as some issues are because of the Vivo S17t devices that are using the internet. Some of these issues are discussed below for your assistance:

• Router Problems

If the internet provider is doing their job right, the router might not deliver you the right thing. Like other electronic devices, they can also misbehave. This can happen because the router is faulty, or it can happen because the firmware is outdated.

• Out of Wi-Fi Range

Why does My Vivo S17t keep disconnecting from Wi-Fi? It is because you might be out of range! The router’s placement is very important. The router transmits frequencies that have a limited range. If you are moving out of the range, the internet automatically disconnects.

• Wi-Fi Signals Getting Blocked

The signals from the router can dissipate from any other electronic device nearby. Signals like radio and microwaves can interfere with signal strength.

• Devices Connected with Router

Commonly, a house has around a dozen devices connected to the internet router. People do not think that the router has limited connection slots. It is unable to entertain a specific number of requests for service facilitation. The router has limitations; the service quality will drop if the limitations are exceeded. This drop in quality can also cause internet disconnection from devices.

• Unstable Internet

If your Vivo S17t gets disconnected frequently, then this disconnection is due to unstable internet, but apart from the above-mentioned problems, there is another reason for internet disconnection.

Sometimes, the internet is stable, but it still disconnects. This is because the internet service provider might not send the best quality internet you have acquired it for. If your internet is stable and the phone still keeps disconnecting, then head onto the next part that will share the top 10 fixes to sort out this issue.

Part 2: 10 Ways to Fix Wi-Fi Keep Disconnecting on Phone

Fix 1: Restart Your Phone

You should check the Router’s admin panel or app to remove your phone from the blocklist.

Fix 3: Reconnect to Network

To fix the annoying problem that your Wi-Fi keeps disconnecting, you should try forgetting the network and then reconnecting to it. This could be done easily by following the steps below:

Having yourselves connected to different set of networks could turn out to be quite problematic in the process.

To finish this irritating issue, you should remove and forget all the extra networks that you connected previously.

You can try and disable them but if that doesn’t resolve the problem, then uninstall the app.

Step 1: For uninstalling the problematic application, you have to select it and hold it. You will see a pop-up menu of multiple options; choose the option of ‘Uninstall’ to remove the app from the phone.

Step 4: After providing the appropriate clearances, you will be asked for another confirmation of resetting the Vivo S17t device’s networks to default. Click “OK” to execute.

Fix 8: Check Routers Range

If your Wi-Fi automatically disconnects and connects again while you are roaming in the house, then it is because of the router’s range; you should check it. For this, you can consider changing and modifying your AP (Access Point) band on your router.

Although the 5GHz frequency band is recognized for providing better network speeds, this band has a shorter range as compared to the 2.4GHz band, which has a better coverage of area. You can easily shift your router’s range through its configuration page. It is considered optimal to utilize the 2.4GHz frequency band for better ranges.
