Class smartphone but with Weeping eye returned for wireless error

So first of all: Buyer I thought to myself, I admit sometimes less known Chinese a chance. Did this decision until yesterday not looked back.
Everything ran perfectly and was adapted to my needs as a casual mobile player, regularly Surfing and Whats App-ender, Seltensttelefonierer, amateur snapshot photographer and occasionally even music-listening.

+ Good performance. Was at the rather small RAM bit skeptical, but everything went smoothly: games, videos, etc.
+ Camera. I realize that a cell phone is not a SLR camera. Of course, like other smartphone models shoot better photos, but to capture moments in which precisely no "right" camera is present, I find the mobile phone as a substitute good.
+ Battery. In normal use the battery lasts up to much about one day, which is very good in my opinion. It is used rarely, to talk a little Whats App, sometimes as short games, the battery has already been through about three to four days loose.
+ Sound. As might be expected, not a real feast for the ears, with headphones but it was okay.
+ Size. My old phone was much smaller, but also here for me (average Women's Hand Size -> no giant paws) is easy to operate with one hand.
+ Call quality. Unfortunately, I had for the first time with a call to Amazon testing regarding the return of the device, but was very pleasantly surprised. Sound great, almost like sitting next to me the nice staff.
+ Design: Did the chic model in red. Although on the back rather a bit pink, but in my opinion very chic is offset in burgundy on the side. The look itself is in my opinion quite high; better than expected at this price anyway.

BIG MINUS !!:
The Wi-Fi. In the first weeks working properly and then said yesterday that it now no longer wants to connect to my home network. The connection was ostensibly there, even the wireless network icon lit up and shows upload and download rate, however, is unknown reasons no Internet. Were performed keinerei changes. Other WLAN networks yet and I have Internet function. At the home network, it is not, other devices have no problem with the network. First thought (by me as a mobile phone lay) was: some mysterious virus. So antivirus software (the EH from the outset it was) can illuminate a complete system -> None. Started router -> None. Wireless access for mobile phones refurbished -> None.

Next step: Googling -> The Android forum knows the problem, but no real solution. For some it works, apps down to throw -> None. My friend has then assumed the poor thing and somehow again checked but found no errors.
That the internet is for me definitely an intolerable situation, which is why I'm going to return the equipment with a heavy heart.

Conclusion: I'm very very sad to have to find out, after nearly a month functioning properly as a stupid and really annoying error (after the forum view probably only applies to some models and not the whole series). I was very happy to have finally found a phone that can keep up quite well with more expensive models, and for that you have to spend a fortune anyway.

If I can give a buy recommendation, I really do not know. In itself, a great part, if one could be sure somehow that this wireless mistake not eventually occur. An attempt is perhaps worth returning on Amazon is absolutely no problem.
Will probably call before returning times with WIKO, should there arise what, I'll update this review.
