Wifi Fixer is a low-resource service for the Android platform that maintains the health of your wifi connection automatically.
It was written for the T-Mobile G1 as a test of the Android SDK after noticing that the wifi connection would often “wedge”, showing connected but unable to send data. That was an application without a UI which would simply reset the association.
Later it became a service, checking the connection, and repairing it automatically.
Wifi Fixer has grown from there, and is now a must-have for anyone who relies on wifi on their Android device.
Wifi Fixer is Open Source Software!
