Router and Network-related Causes

DNS and Network Congestion

A common reason why VPN connections may be disrupted is due to issues with the Domain Name System (DNS) or network congestion. DNS is responsible for translating domain names to IP addresses, and if the DNS settings of your router and VPN are not aligned, it could lead to inconsistencies and disconnects. To resolve this, make sure your VPN client’s DNS settings match those of your router. Alternatively, consider using a different DNS provider, such as Google’s public DNS, for improved stability.

Network congestion can also impact your VPN connection, as it increases the likelihood of data packet loss between your device and the VPN server. To mitigate this issue, try connecting to a different server, or use your VPN at off-peak hours when network traffic is generally lower.

Device and Channel Bonding Issues

Some routers offer channel bonding as a feature that aims to increase the bandwidth of your Wi-Fi connection. However, if your VPN client does not support channel bonding, it may introduce latency and instability to the connection. To determine if this is the cause, you can try turning off channel bonding in your router’s settings. Additionally, ensure all devices connected to the router are VPN-compatible, as certain devices may pose compatibility issues, leading to erratic VPN behavior.

Network Connection Limitations

Every VPN service provider imposes a limit to the number of devices that can be connected to a single VPN account. If the allowed limit is exceeded, your VPN may start disconnecting randomly. To prevent this issue, be conscious of the number of devices connected to your VPN account and ensure you remain within the limits set by your provider. If you routinely need to connect more devices, consider upgrading your subscription or switching to a VPN service that supports more simultaneous connections.

Furthermore, network connection issues can affect the stability of your VPN connection. Factors like weak Wi-Fi signals, interference from other devices, and even the physical distance from your router can impact the performance of your VPN. To minimize these issues, make certain your Wi-Fi signal strength is strong, avoid interference from other devices, and position your router in a central location within your home or office.

Software and VPN Provider Related Issues

Compatibility and Software Conflicts

One common reason for VPN disconnections is the presence of software conflicts between your device, the VPN software, and other applications running on the system. This could happen when your antivirus or firewall clashes with the VPN software, or when there are multiple VPN clients installed on the device. To mitigate this issue, ensure that you only have one VPN client active on your device and review the settings of your antivirus and firewall to prevent conflicts.

Server and Maintenance Factors

Another factor that could cause your VPN to keep disconnecting is server-related issues. Overcrowded VPN servers or high latency due to large physical distances between you and the server can lead to disconnections. Moreover, maintenance or updates performed by the VPN provider can also cause temporary downtimes. To avoid such issues, consider choosing a VPN with a vast server network and select servers closer to your location to minimize latency.

VPNs and Device-specific Settings

Lastly, your VPN may disconnect frequently due to device-specific settings or restrictions on your Android device. For example, devices often put background applications to sleep to improve battery and performance, causing the loss of VPN connection1. Also, some default network settings might interfere with the VPN connection. To tackle this, check for any device settings that could cause disconnections and adjust them accordingly. Ensure your VPN software is updated and compatible with your device’s operating system.

Security and Privacy Concerns

IP Exposure and VPN Drops

A major concern with VPN disconnects is the exposure of your IP address, which may allow anyone monitoring your network activity to identify you. VPN drops occur when your connection to the VPN server gets interrupted, leaving your IP address exposed during the disconnection period. It’s crucial to maintain the connection so that your privacy remains protected. To reduce the likelihood of VPN drops, ensure your network connection is stable and try using a VPN server closer to your location.

Kill Switch and Security Features

A Kill Switch is a security feature that automatically disconnects your device from the internet when your VPN connection drops. It is designed to ensure your IP address remains hidden and your online activities are not exposed. Many VPNs offer this feature to handle sudden disconnects and protect your privacy. Make sure to enable the Kill Switch in your VPN settings, and if your VPN doesn’t have this feature, consider switching to another VPN service that does.

Encryption and Obfuscation Technologies

VPNs ensure privacy and security by using various encryption and obfuscation technologies. These features protect your data from being intercepted and read while being transmitted over the internet. Common encryption protocols include OpenVPN, L2TP/IPSec, and SSTP. While these encryption methods secure your data, not all networks or countries allow VPN usage. This is where obfuscation technology comes in, which helps in disguising your VPN connection as regular internet traffic so that it can bypass network firewalls and censorship.

Keep in mind that not all VPN services offer the same level of encryption and obfuscation technologies. It is essential to choose a VPN with powerful encryption and advanced security features to avoid exposing your IP address or putting your data at security risk.

Troubleshooting VPN Disconnection Issues

ISP, Throttling, and Port Choices

One potential cause for VPN disconnections could be related to your Internet Service Provider (ISP). ISPs may sometimes throttle bandwidth, which can lead to slow or unstable VPN connections. To mitigate this, try switching your VPN protocol to OpenVPN TCP if you’re currently using OpenVPN UDP, as the TCP version can be more stable due to its error-correction capabilities.

Additionally, ISPs may block certain ports, leading to disconnection issues. To resolve this, experiment with different ports used by your VPN client. Most VPN providers offer multiple port options, so consult their documentation for guidance on how to change them.

Switching VPN Providers

If you’re experiencing frequent disconnections and have ruled out other possible causes, it might be time to consider switching VPN providers. A different provider may offer more stable servers or protocols that better suit your needs.
