IMPORTANT NOTE: This app is for an old bug in old devices, and just few new ones. So in most cases it wont fix your problem. Many people get upset because they have another different bug in their devices, but it is not intended for those other bugs, just the old one.
If you can't reconnect to your WiFi until you reboot your device, Wifix (lite) will problably help you.
Just click the "Reassign" button and about 8 seconds later you will be reconnected to you WiFi. You can use "Reconnect" if it doesn't work for you.
There is also a "Keep WiFi" checkbox that prevents your wifi connection from been unactived. You can also keep CPU activated and the Screen unlocked.
