[Q] No wifi on screen off? - Android Q&A, Help & Troubleshooting

I use EasySMS app to sens text messages from my phone by typing them on my laptop. Laptop connects to EazySMS through Wifi. It works when the screen is ON, but when it goes off, the http interface no longer works (page not found errors). I then need to turn on the screen again to regain connectivity.
EasySMS has an option 'Keep wifi connected (drains battery)' and I already have it ON.
At the same time, AirDroid works fine over wifi even with screen off.
What could be the problem?

Hi
Tray
Go to the settings - wireless & networks - Wi-Fi settings- then click right - Advanced-second option change to never.

Turned out DISABLING "'Keep wifi connected" made it work. How logical...

Wifi switching itself off

HI all i have a G2 Touch unlocked running Modaco's latest rom and i cannot get the wifi to stay on longer than about 5 seconds. It does search and find networks and i have managed to put in the key for my orange box but in settings/wireless controls/wifi the box stays ticked and underneath the words WIFI it says disconnected. Ive gone to advanced and told it to never switch from wifi and this is remembered but as i said it lasts all of 5 seconds then disconnects and i have only once seen the wifi icon in the task bar once for 5 secs then it went !! Any advice would be much appreciated thanks.
Maybe the signal's too weak and it looses connection?
No it doenst actually ever connect, the wifi program on the phone cuts out way before it ever finds a connection.
Just making sure you've done this:
Go to Settings -> Wireless Settings -> Wi-Fi settings -> Add WiFi network. Then enter the SSID and necessary security information. After all that turn WI-FI on
Thats what i do still just cuts off after maybe 5 secs !! I give up looks like i have a Hero that doesnt like wifi
Hmm, it seems that I had a similar issue, but I had enabled the Y5-Battery Saver and it continuously switched off my WIFI when I was in place where I had not been connected before. Just wondering if you have enabled the same app...

Wi-Fi tethering problems

Hello. I have a problem with my O1 Wi-Fi tethering feature. After enabling it, the mobile internet connection restarts (the data indicator turns off, then on again). My phone and connected devices don't have net. Only the up arrow of the icon blinks in white. After I disable the tethering, I have to restart the data connection to have net again... Any help????

[Problem] QS-i9300-KK 1.9+

Hi!
I can't post direct to developer forum... so
I have strange wifi problem with this rom. Wifi switch is always ON and settings Keep wifi on during sleep is Only when plugged in. After reboot works everything well. Over night or after few hours when screen is off I turn screen on, wifi switch icon is OFF. It looks like wifi turned off, no wifi networks appears, but wifi works well. When I try turn wifi ON, icon shows in half ON state and works further well. Because of this, I can't switch wifi off. Then suddenly after few minutes/hours (randomly) wifi switch shows ON.

Wifi problem on CM12.1

My wifi doesn't automatically connect when a known wifi is in range unless and until I turn the screen on. Means when it's sleeping, it won't connect to any known wifi. If its already connected to a wifi network and if the screen is turned off after that, it stays connected. But lets say power goes off and wifi disconnects because of turning off of the router. When power comes back, and router is automatically switched on, the phone doesnt reconnect automatically when in standby. It connects immediately as soon as I switch on the display. Wifi scanning, keep wifi on during sleep and all those options are enabled. But it still doesnt automatically connect to any known wifi when in standby...I have to turn on the display for that.
Any solutions?
Same issue on lg g3 and xperia z2

Turn wifi on automatically

Hi all,
I have a problem
Samsung S9+ / Oreo 8
WiFi does not automatically turn on near saved networks any more.
Have tried:
-restart phone
-reset network settings
-put on airplane mode
-make hotspot
-uncheked the option, restart the phone,check the option
When i turn the WiFi manually it Auto-connects to the saved network.
Android build
R16NW.G965FXXS2BRI1
Phone does not enable the wifi automatically in places where I have the wifi network saved.
Network wifi is checked to "Turn on Wi-Fi automatically" and in Improve accuracy settings, Wi-Fi scanning and Bluetooth scanning are also turned on.
When I am at home or in a place where I use the saved wifi network, I must enable the wifi manually (toggle the wifi button on) and the phone connects to that wifi with no problem.
I aven tried to boot in safe mode and see if there it enables the wifi automatically and it did not. What i did:
-disabled manually the wi-fi
-restarted the phone into safe mode
-the wi-fi staid disabled although the option to turn on automatically wifi and wi-fi scanning were turned on. the wifi signal was full bar also.
I have noticed that when disabling the power saving feature(which was on medium with background data enabled) my wifi network was added to frequently used networks. I disabled it manually and restarted the phone. When the phone booted, the WiFi turned itself on.
Then i enabled the power saving feature also on medium with background data enabled, i turned off the WiFi manually, immediately i got a notification that my network was taken out from frequently used network. I disabled the power saving feature, restarted the phone and again the WiFi does not turn automatically on.
