Xperia Z Wi-Fi authentication problem, Tethering problem...

Ok, firt off le me say hi before i start nagging on how i cant get the **bleep** wifi on my phone to work xD.

Now that i got that off here's the deal, i bought this device 2 days ago USED and while i was setting it up after  a full reset when it came to Wi-Fi i ran into a problem, the Wi-Fi picked up my home network and i was 5-6m away from the router but when i tried connecting the device to the network it just went like this

connecting->saved->then the network strength fel to 0 for 1 sec and then -> authentication problem

i started looking into solutions for this and i always found that the router might be the cause of the error in 90% of the cases, i tried changing my routers encription and even removing it but i still got the error, i tried makinf a hotspot on my laptop and 2 other phones and the error is still there, i upgraded the firmware of the device from android 4.4.4 to 5.0.2 and surprize surprize, it's still there, everything other works just fine on the device but that Wi-Fi is just killing me right now, it's like in itch i cant scratch on my back, also when i tried USB tethering along with portable Wi-Fi hotspot and Bluetooth tethering i got that "Tethering Error (Error occurred during tethering)" message, that's about all i can say for now, i did try repairing the device through Sony PC Companion but it didnt do anything to it, any solutions for this cause i have no idea what to do to it anymore, is the Wi-Fi dead?, can it be repaired?, i really hope someone can fill me in on this

ok so i am happy so say i kinda resolved the issue, since any software changes/repairs didnt help and there is no xperia care in my country i decided to take things in my own hand and i am laughing my **bleep** off cause it actually worked it seems that wifi antenna or something in the phone got loose as it could register the network and everything else but the signal dropped to 0 as soon as connecting started, i took the phone and started slamming it at the top of my hand screen first, i was careful not to damage anything and it seems the loose part got back in place and i got my connection back, i am seriously laughing my brains out cause this method worked for me xD

I'm assuming that this happen with different routers? 

it'll be wise to contact your local Xperia care
