After a week of being a happy Sony Xperia ZR (4.1.2, C5502) owner, my wifi stopped connecting to networks. I can't connect to any network I have tried, but the list of networks is ok. It stopped working suddenly. My previously used networks are all marked as "Saved", but when I try to connect the following happens:
1) Saved (doesn't even change when tapped)
2) Connecting -> Saved
3) Connecting -> Authentication problem -> Saved
After half day without wifi, this is what I have tried to fix it:
1) Restart phone
2) Restart phone, take out battery, SD card and SIM card
3) Restart wi-fi router
4) Connect to another network
5) Forget network -> Type password again
6) Connect another Android device to the same network
7) Connect another non-android device to the same network
😎 Sony Companion -> Repair
Nothing fixed the issue, still the same problem. And now the grand finale:
I packed the phone into the box and went to cook a delicious stew which took about 3 hours and filled my apartment with heavenly smelling goodness. I came back to check whether there are any data in the phone and it started to work again. Just like that. I did not do anything.
Now please anyone tell me, is this going to happen often? Because if so, I am going to make a youtube video "How many hits by hammer can Sony Xperia ZR take" and buy HTC One.
Also if anyone wants the recipe for the stew, let me know.
EDIT: It worked until it lost connection. I have discovered that sometimes it works, but immediately after losing connection, back to square one. So far I've tried about 15 different wi-fi routers and networks.
