[Q] N9776 JB 4.1.1 k3.4 issues?

Hi all.
I'm having issues with my n9776 4.1.1 kernel 3.4.
firstly, WIFI and Mobile data lock up, and I have to restart the phone.
Also when the phone goes to sleep and I wake it sometimes the wifi states my networks are out of range even if I rescan. I have to turn the wifi off and then on and it connects automatically.
Also is there any way to get the notification bar from the 'fake JB' working on this version? I liked the fact that if one sim was missing it would hide that signal meter, this latest version doesn't.
Any help would be appreciated,
Thanks.
UPDATE:
It turns out that aquamail was causing all the problems, In settings there was a tick in WIFI IN SLEEP MODE. Deselecting this cured the wifi and data problems.

Wifi drops

I often encounter with specific router's wifi drops on my E2303. It looks like: You are connected to your wifi and everythink seems fine. But at the moment it stops working. Then if you try to reconnect it says "Connecting..." and indicates the lowest signal in the picture. Then it brings "Saved" and indicates the real signal strenght and it's repeating again and again forever. This problem fixes itself about in two days, but when it starts, the only way to fix it at the moment is router reset. Even after flashing these drops' problem consist permanently. Maybe someone knows how to solve it. I would really appreciate that.

Same Problem
Im having the same problem on my E2303, a source www orduh com/fix-sony-xperia-m4-wont-connect-to-wi-fi suggests that it may be a firmware issue. Hopefully a fix will be released soon.
I dont think that is firmware problem because I just flashed .167 firmware while dropping and even after flashing these drops consist. I think it's hardware or router problem. How in diffrent way phone can remember it? I think need to configurate router settings or something.
Aqua M4 E2303 problem
I have same problem. And one more. When I return to home from outside or come to my office, Aqua M4 want connect automatically to wifi network(I don't use mobile data).
I must press the power button and then wifi will turn on and I get all emails and viber messages.
I was in sony service center lot of times and at the end, they gave me new sony xperia aqua m4 but with same bug. I noticed that on this phone Aqua M4 is no message about a new wireless network found, ever.
I tried with few firmwares and same bug happens. Wifi signal dropping and when is in sleep mode and I turn off the wifi ruter and on after 1 minute wifi on Aqua m4 is death all the time.
Couple of friends have xperia aqua m4 E2303 with same problem.
Hey. For me it resolved when I changed from automatic to specific (2.425 or doesnt matter) ghz on adb router. And somewhere I found that wifi problem resolves changing channel to 6 and 40 mhz in case of auto for tp-link or other routers with such options. Reply if it worked.

How to increase wifi connectivity range?

I was in EU rom,there was low wifi connectivity problem there.Then i moved to global rom and nothing improved.Is this a limitation of this phone?Or am I the only one who is facing this?
Does anyone have any solution?
In compare to my poco f1, the WiFi connectivity range is garbage. Its similar for Bluetooth.
Yes, the WiFi-connectivity is worse than my previous phone (Xiaomi Redmi 2).
But the connectivity improve some what after turning off mobile data. It looks like when the WiFi-signal is weak, the phone prefers to connect (or switch) to mobile data. By turning off mobile data, the phone will be forced to connect (or stay connected) to WiFi.
It would be nice if the user can tweak how weak the WiFi-signal (RSSI) must be before the phone will skip connecting to the WiFi access point.
