but with an Acer Liquid E3 Plus - Dual Sim - E380 - After upgrading to Androird 4.4.2 - Kitkat. Before Upgrading everything worked fined.

 

Now the Wifi is connected but no data is going through. I ping to the wireless router is bringing the connection back to live but after a certain amount of time it is dead again. This could be 5min, 1 hour, 4 hours…

 

Tried so far:

 

1. Delete the Wifi-Connection and setting up new one.
2. HardReset of the Phone
3. Turning off Wifi Power Saving
4. Wifi setting always on

 

There is a Bug Fix in the newer Android 4.4.3 for a “WiFi Auto-connect” Problem maybe that’s the Problem!?
