WLAN Problem after change the Digitizer

[Xperience Z]

Hello guys.

my problem is following:
after my frontglass broked i had changed my full Digitizer (not just the display)

Now I'm 3-5 meters away from my wifi router and have connection problems.
1. the signal is at 25-50% (5 meters away from the router)
2. If I go to another room, I have no more connection now.
What can I do to fix this?

Device: C6603
Digitizer: No more original
OS: CM12.1 (Android 5.1.1)

OS: CM12.1 (Android 5.1.1 custom). But before changing digitizer everything worked without any problem. So must be a hardware-whammy. although the c6603 has always been very susceptible to wireless problems.

I would:
Flash full stock ftf, factory reset router and try again.
If problem persist, open phone again and check WiFi antenna connection.

Yeah but bad WiFi connection sucks too lol
This is what I would do, what you do is your decision
Besides an ftf does much more than a rom.
