Boost Weak WiFi: Turn an Old Android Phone into a Free Repeater
Facing frustratingly slow or spotty WiFi? A simple solution could be lying dormant in a drawer: your old Android smartphone. A readily available application allows users to repurpose older devices as WiFi extenders, offering a cost-effective alternative to purchasing modern hardware like mesh systems.
The “WiFi Extender” app, updated on September 4, 2025, available on the Google Play Store, enables users to extend their existing WiFi signal or instantly create a local area network (LAN). The app has garnered over 100,000 downloads and currently holds a 3.4-star rating.
According to user reviews, the application’s functionality varies. Some users report successful WiFi extension, while others note issues with connection sharing or signal visibility. One user stated, “There is a network created but no sharing of internet connections with the original WiFi, so it’s useless if you need the 4G connection – no app needed to share via WiFi, just activate it in the phone options.” Another user found the app to be “great, practical and free.”
The app developer, Nguyễn Thị Thanh Trang, can be contacted at trangnguyen19091310@gmail.com. The developer’s privacy policy indicates that no data is collected by the application, and data is encrypted during transmission.
This approach to extending WiFi coverage aligns with a growing trend of resourceful tech solutions, allowing consumers to maximize the utility of existing devices. A March 18, 2026 article from ZDNet details how to turn an old Android phone into a WiFi extender, noting it’s a free, easy setup that avoids the need for mobile data usage or upgrading to a mesh network.
The possibility of using an old Android phone as a WiFi repeater has been discussed online, as evidenced by a Reddit thread from March 12, 2022, found here.
