T231 wifi problem after screen turn off - Galaxy Tab 4 Q&A, Help & Troubleshooting

I have SM-T231 and i am using Russian firmware, Android 4.4.2. I have a small but very annoying problem which i couldn't resolve no matter what i tried. My wifi connection doesn't work after my screen turns off.
Wifi connection is set to turn off during standby mode to save battery power. I see that the wifi connection becomes active after i wake up my tablet with power button but i receive no data whatsoever. It doesn't get fixed `till i turn off and on wifi connection manually. I tried to use static ip feature by thinking that maybe my router causing the problem with dhcp but this didn't help.
Anyone have an idea what might cause this very annoying issue?

Wifi widget sometimes doesnt work

Sometimes ill push my wifi wiidget and it will Jehoshaphat that it is on but it wont connect to my network. If ithen go to settings, then wiring, it will start connecting.
Anyone have a similar issue?
Are you talking about the power control widget that comes with the phone?
Yes.....
In that case then yes, my phone doesn't auto connect to my network when I turn on wifi I have to go into settings too.
I've been having issues with my phone staying connected to wifi also. It's become quite annoying.

Connect to WiFi network timeout?

Hello. I'm sure that this must have been discussed but I cannot find the answer using search. As is surely normal, I use WiFi within the home and GPRS when there is no WiFi available. If WiFi is connected and I go out for a short while, then when I get back in a WiFi area, the WiFi is still connected. However, if I go away for a long time, and GPRS is used for perhaps a regular weather update, then the WiFi disconnects and has to be manually reconnected upon return to home. This leads to GPRS being used in a WiFi area unnecessarily if you forget to re-connect WiFi. Is there a WiFi connection timeout value or any other setting that can be changed? My old TyTN II did not have this problem. Thanks.
Try this CAB
It disable disconnecting WiFi when phone is in sleep mode and with this phone automaticly connects to WiFi when Leo will be in range.
Thanks Franq_23_pl. I think that the CAB just stops WiFi disconnecting when the device is in sleep mode. That will just drain the battery, surely? My old TyTN used to disable WiFi when in sleep mode, but as soon as you switched it on again, WiFi would be enabled and it would connect if in range. The problem with my HD2/Leo is that if I am away from my WiFi for some considerable time (ie, most of the day), then when I get back home and switch the device on, WiFi is disabled, and I have to manually toggle in on. So my question is..... What are the circumstances that cause WiFi to disable itself, and Is there some way of stopping it happening?
OIC now. I think you having some battery saving app and this app turning off WiFi when iz not used. What apps or registry mods you have installed on Leo?
You have the same behavior after hard reset?
My Leo don't disable WiFi. When i go outside (for ex to work) and back after few hours my Leo connecting to my home wireless network automaticly.
I remember, that i had the same problem like you and it was caused by app, which had duty to save battery.

Wifi does not connect after sleep

Not a huge issue but for some reason when I turn ON my TF from a long sleep/hybernation (1hr+), it will lose it's wifi connection to my house but the icon says that it is connected (but with no internet access). The only way I can fix this is by turning off and on the wifi. I would rather not have to do this. Is there a way/fix for this issue so that the wifi will reconnect once the tablet wakes?
Thanks!
This is one of several bugs that I am starting to fined annoying. I have to leave wifi as always on rather than disconnect on sleep.
The other issue is browser closing...still no fix for that either.

Wifi and GoogleServices major problem

Hi all!
I have an international version of the S3 with a weird problem.
When I have Wifi connected my phone can't sign in to Google talk and wont receive notifications. I can browse and download stuff though.
If i switch to 3G all is well and working. I have tested on different networks and I have a galaxy tab 10.1 connected to the same wifi without problems so it's no ports in the firewall that's causing it.
If I restart the phone it works for about a day then it fails again and I have to restart the phone to get G-talk over wifi.
I have tried setting the phone a static IP, switched "Keep wifi on during sleep" on and off, tried the trick with power saving in debug menu but nothing helps.
Has anyone experienced the same and can someone maybe suggest a fix?
Best regards
Erik

WIFI Issues

I've had my Nexus for about a week now and noticed two strange issues with the WIFI connection.
1. I can connect to WIFI successfully at home but as soon as I go out and it switches to the 2G network and then later go back inside the WIFI doesn't auto connect it will stay on 2G, I have to disable and enable WIFI to connect to my home WIFI, is there a way round this or is it a bug?
2. Whenever I'm out an about and the phone detects a WIFI network even if its not configured to connect to the WIFI network the phone seems to disable 2G Data connection and continually notifies me of a WIFI network being in range and wanting to configure it, is there anyway of disabling this behavior and allowing the 2G Data connection to be active when no configured WIFI network are in range?
Any help would be much appreciated.
Thanks
Jon
Really can't help you much on the settings as I don't quite have my N4 but you should always turn wifi off when you're not using it. You will get much better battery and you wont have problem with #2. Sorry I couldn't really help much.

I have the same issue number 1. I find the battery is getting used quickly and the wifi will not connect. if i disable then enable, it quickly connects to the known wifi signal. I can see a different battery decay slope if I let this problem persist for a few hours, it then reverts to its usual slope once wifi is restarted. This problem usually only occurs once a day on average. I hope someone knows how to solve this issue.
cheers
