[Q] Wifi problems Samsung Galaxy Ace

Hi all,
Just bought a new Galaxy Ace for my girlfriend and I can not seem to fix the following problem.
When the phone falls in standby the wifi falls away.
Yes before you says so. I checked in the option menu in the wireless section. And I put it the option to never fall asleep.
So why does it still fall asleep?? I reinstalled the phone a few times. even changed it at the store for a new one. New one has teh same problem. Tried some wifi fix programs from the maket but same thing.
My galaxy s2 stays perfectly connected at my home router!!!
I am clueless... Anyone can help me?

[Q] Nexus 5 No Service issue

Hello everyone,
My mother owns a Nexus 5. Some days back her phone hanged so we waited till the battery depleted and it turned off. On turning it on we noticed that the phone didnt get any network. Tried almost everything but nothing worked. Then I switched to a test sim and the phone could catch the network but didnt work again once I inserted my mom's sim. We got a new sim but the same issue ( test sim and actual sim are on different operators). Can anyone recommend a solution?

S7 finds very little wifi acess points

Hello, I recently purchased S7.
The problem is that my S7 doesnt find much wifi acess points. For example, my friends xiaomi finds wifi and connects to it, while mine S7 doesnt show me wifi spots at all.
Now i took my tablet asus zenpad and S7. I put them in the same place and turned on wifi. So my asus finds about 12wifi acess points, while S7 shows me only 4.
What can be wrong with S7?
I really would be gratefull for help!
IS this some phone defect or S7 has very bad wifi reception or maybe something is set in settings that causes this?

Mobile networks problems after repairing my phone at shop for water damage

Hi
I have a rooted Galaxy note 5 phone SM-N920C model.
Some water got into my phone and i had to take it to a phone shop to get it fixed its was working fine after the water damage but the power button had to be pressed hard to work.
the repair guy told me he had to replace several some parts i think some cpus.
After i got my phone my sim would work and then randomly stop working and i couldn't make calls nor will mobile data work. Then randomly it would work again and stop randomly.
i tried my sim in another phone and it was working fine, even tried my friend's in my phone and it had the same problem.
An important thing that i found is that the model in my device info has changed from SM-N920C to SM-G935T Aka Samasung S7 Edge.
after a couple of days i figured out that outside the house the mobile network works fine but inside it it doesn't might have to do with the signal i'm getting from the device. So im thinking of this an error from the guy who fixed it so i'm going to return it to him.
Things i did trying to fix it : flash all kind of different roms, unrooted, rerooted and also tried to install S7 Edge roms also tried the S7 Edge stock rom.
