Description
Connection Stabilizer Booster is designed to tackle internet connectivity issues on 2G, EDGE, 3G, HSPA+, 4G LTE, 5G NR and Wi-Fi wireless networks.
If you are having trouble with your WiFi or mobile data connection, this is the app for you. Loaded with lots of powerful features, this app delivers a stable mobile internet connectivity.
★ Active Keep Alive ★ Does your wireless service provider disconnect your 3G, 4G LTE or 5G data connection after a certain period of inactivity? Does your WLAN connection drop unexpectedly? Is there no data transfer even when connection is live? Queueing delays, packet loss, and blocking of new connections are typical problems in busy networks. Active Keep Alive along with Reset on Failure feature keeps your connection working in such cases. It keeps traffic flowing between your device and the internet via your ISP’s infrastructure. It attempts to optimize and enhance your internet experience by holding your spot and preventing timeout. The network may assign a higher priority to your device, resulting in significant improvement in network performance, especially in poor network conditions.
★ Active Reconnect ★ Does your device often lose data signal and fails to reconnect even though network is available? Do you miss out important chats, calls and emails until you turn mobile data off and on, maybe multiple times to get reconnected? This is a known problem caused by handset or mobile network operator issues. The app comes with an automatic reconnector called Active Reconnect. It monitors and re-establishes dropped connections. It automatically reconnects your 3G, 4G LTE, or 5G mobile data connection as soon as it gets disconnected. On newer android versions, this feature needs root or additional setup to work.
★ Force Connect ★ Repetitively attempts to connect to internet and establish mobile data connectivity. Useful in adverse network conditions.
✔ Helping users around the world since 2014 ✔ Support available via email ✔ It can fix 3G, 4G LTE and 5G NR internet connection problems on T-Mobile, Verizon, Sprint, AT&T, Vodafone, Telkomsel, O2, Boost, Metro, Telekom, Airtel, Jio, or any other carrier. ✔ It can help in holding connection in busy or weak wireless LAN or cellular networks.
PRO TIPS ➤ If you are facing random disconnection problem, activate Active Reconnect. It will automatically detect connection drops and actively reconnect the connection.
➤ If you are having trouble in establishing connection to the internet over the mobile network, use Force Connect button on the dashboard to immediately try forcing the connection.
➤ If your cellular data or WiFi disconnects after a period of inactivity, activate Active Keep Alive. You can adjust the ping interval from the Active Keep Alive settings to find the setting which works best for your network.
➤ If you are facing any other problem with your connection (e.g., no data transmission even though internet is connected), activate Active Keep Alive with Reset on Failure. Its ping and reset actions are known to work wonders and mitigate congestion related network issues.

DISCLAIMER An app cannot directly increase the power of cellular or WiFi radio signals. However, there are a lot of variables at play in wireless networks. This app focuses on maximum possible utilization of available network resources and maintaining a stable working internet connection. This in turn boosts your wireless connection experience.
IMPORTANT INFORMATION → When Active Reconnect is enabled, don’t turn off the mobile data connection directly from your device. Instead, press the data setting ON/OFF button on the app's dashboard or deactivate Active Reconnect before turning off mobile data from android settings.

Comments on Connection Stabilizer Booster for Android
★★★★★Gina Harrison· Jun 27, 2026
I Love this app! It really helps maintain the connection when you're a little ways from the Wi-Fi. The older version had the ability to 'Reset The Connection' 10+ years ago but newer versions require a tethered computer or activating developer settings for some functions to work. THIS IS ONE AMAZING APP! It has helped keep me connected to unstable Wi-Fi router signals in multiple locations for free almost every day for the past decade or more. Thank you Devs for making our lives much easier!
