Wi-FI Problems... - Galaxy Tab S2 Q&A, Help & Troubleshooting

I have an issue with my Samsung tablet. What happens is, I can have it connected to Wi-Fi for a random amount of time and then once I stop using the tablet and let it go into idle mode or whatever you want to phrase it as more times than not when I try to have it connect back to Wi-Fi the Wi-Fi icon will be on but it will not find any Wi-Fi hotspots or locations even though I am in close proximity to one and the only way to fix this problem is to restart the tablet every single time. I don't know what's causing this how I can fix it I've done a reset on the tablet but all user data still remained so I don't know if anyone else has experienced this or not?

I am having the exact same issue, I have found that if I just toggle the wifi switch it corrects until the next time I put tab down for a while, there is a setting in wifi advanced that that asks if you want to put wifi to sleep when not using. Problem was much worse with that checked off. Since I unchecked tab only won't connect after sitting with screen off for a while. So I assume it has to do with waking up the wifi controller etc.

Online radio streaming on nexus stops with screen off.

Have you guys have the same problem?tryed all the radios on the market..they stream perfectly on wifi ,but when i lock the screen it just stops streaming.If i turn the screen back starts as normal.Any idea how to get over this?
No problem for me with lastFM.
This should work ... but it doesn't
Just in case you haven't tried - in the settings menu, Wireless and Networks, Wi-Fi settings, then press menu again and find 'Advanced'. Here lives 'Wi Fi sleep policy'. It looks promising, the obvious move is to set this to 'Never'.
But it doesn't solve the problem. Like you I'm finding that it is a problem with all radio streamers, some worse than others. If I turn wireless off and use 3G its fine.
Thanks for posting the issue. I thought I was the only one.
No problems with TuneWiki over WiFi and 3G...
i find that even if you set the wifi never to sleep it still does. i frequently use aftp to transfer movies and stuff to my phone over my lan, so ill set it to transfer like 3 gigs of stuff and go to bed, even though its set never to sleep the socket still gets closed at some point at night. so id say your problem lies with wifi sleeping.
also some online radios stop automatically after a certain amount of time incase you arent listening anymore to save bandwithd
Maybe its in the app settings. You didnt specify which app it was also...
This might help
When you connect Wi-Fi make sure to turn off your cellular network. N1 has this weird problem where in as soon as screen is off, it drops the wi-fi connection and goes on to cellular network.
So if you switch off ur cellular network it maintains its Wi-Fi connection even when the screen is off.

i use mainly "AOnline radio" but i have tryed pretty much all from the market and all do the same. trying with the settings now..post if any change.
edit:yea still stops...strange try with gsm off and still same thing...is it there any solution to get over this thing?i just liten now with the screen on) eats the battery..it's ok but why not better?
The Nexus one activates some kind of energy saving mode as soon as you turn off the screen. This makes the WiFi connection very laggy, though stable for me. This is independent of the WiFi sleep policy. There's a bug report because of this for Sipdroid and I've also seen this issue while being connected to the phone via SSH. The connection is just fine as long as the screen is on, but if it's off, there's about 1 second delay.
However, I never had the problem you describe. Droidlive, for example, works just fine.

i will check droidlive myself right now...thank you for explinations..is there a way to talk with cyan and maybe he could overpass that wifi sleepy thing.
edit: also noticed if you ahve a download or something and turn the screen off goes very slow..so this problem i think really have a priority to be solved.
edit2:still stops...what would be the thing?wifi priority changed.do you have any type of settings?full app?
I'm listening to a ShoutCast stream with AOnline right now, using WiFi, screen is off. Works perfectly. Do you see this problem with other access points, too?
SLightworkaround....
If you can keep it plugged in...set the SCREEEN TO NEVER SLEEP...under settings>>>applications>>>DEVELOPMENT>>>STAY AWAKE... hope that helps!

This is the problem yes... Just try to ping your N1 while turning the screen off/on... Ping jumps up as soon as the screen is turned off...
For me Streams stop when I have a weak signal to begin with, which does not get better when turning the screen off
"KeepScreen" might help...

Dead Wi-Fi connection after sleep

I'm on university wi-fi. I think it's 802.1x, requiring username/domain and password. Which kinda sucks cause Chromecast doesn't work. But anyway, just about every time I turn the screen on, the wi-fi appears connected, but YouTube and facebook just give loading spinners and I think eventually time out. I have to switch the wi-fi off and on again to get the wi-fi to actually work properly. I don't have the same problem with my laptop, so I'm thinking it's a problem with my Note 3. I'm using rooted NB4 if that makes a difference. Any ideas?

[Q] Wifi turns on uncommanded

Curious if anyone else has this problem - 32gb GS6 w/ T-Mobile. Two or three times a day, wifi will turn on and stay on of its own accord. I have location services using wifi enabled, but this is obviously not supposed to leave wifi on and connect to networks, so if that's the problem it's clearly a bug. I can't imagine what else would be causing this and don't see many other people posting about it, so maybe my phone is the problem?
Go to advanced settings and turn off auto connect and always scanning. Advanced settings in WiFi settings.

Moto G (Dual Sim) Internet Connectivity Issues

Hi, I'm new here so forgive me if I do something wrong^^
First of all, I have a Moto G 2014, Dual Sim which is running on 5.1.1, to be more specific, this ROM. I was using this ROM for about 4 months already so that shouldn't be the issue. My problem is that after my phone connects to the internet, usually using H+. The connection to the internet is working perfectly fine, but after a while of not using the phone it loses the connection. It still tells me that it got a strong H+ connection, but nothing (browser, apps, anything) is able to connect to the internet. Enabling & disabling airplane mode usually fixes the problem. From time to time it also happens, usually when I lost some sort of wifi connection (regardless if I disabled wifi or I got out of range) it happens that it shows full connectivity but with an exclamation mark. This only goes away if I reboot or enable & disable airplane mode again.
Is this issue known/is there any solution to
I have been experiencing the exact same thing as of lately. I thought it was a byproduct of downgrading from (Stock) Marshmallow to (Stock) Lollipop (yes! it's happening even on stock ROM) where at times the WiFi losses connectivity when the phone had been sleeping for awhile...even though I have the "Keep WiFi on during sleep" option on under WiFi's advanced settings. I had no idea that it also happens with data connections ! ...as I don't use it (too expensive for me), now I'm uncertain what could be the cause. I can see how this would be an inconvenience if you use a lot of social media apps as I sometimes do not get my WhatsApp messages when this happens and sometimes I don't even receive my Hangouts messages until I open the app manually.
It's strange, at times when my phone sleeps for awhile and it losses connectivity and I wake it, it will reconnect just fine and other times it just goes into this state where it reconnects with full signal strength but with an exclamation mark next to the WiFi icon in the notification bar. When this happens, no matter what I try it stays in this state, I tried turning off WiFi and turning it back on, also forgetting the network and entering the info and reconnecting to it but none of that works. I didn't know that turning on and off airplane mode can help....I'll have to try that one, rebooting the phone was the only solution I found which is just inconvenient and somewhat annoying.
I too, am interested in a proper solution. I don't know why the phone ignores the "Keep WiFi on during sleep" option or why at times it connects but have not internet access! It should be noted that it's not a problem with the network, It's not due to an incorrect password or anything like that as I am the one that administers those things and when it happens other WiFi devices such as my Tablet PC, Laptop etc can connect and access the internet just fine and it only happens sometimes on the phone (Moto G 2014). This doesn't seem to happen in Marshmallow...but I hate Marshmallow and I can't remember having this issue on Lollipop post Marshmallow update (how I wish I had never tried out Marshmallow!!!), which is why I thought it was related to downgrading, .......did you downgrade ?

[Q]Suddenly losing WIFI connection when phone is idle

Hello.
I am using my I9000 for a good while now and i am running cm11-20150901-SNAPSHOT-XNG3CAO3G0-galaxysmtd. Everything was running fine so far, but suddenly for some days now, the WIFI connection somehow gets lost when it's idle.
When this happens (and i don't know on what timeframe it does) and i activate the phone (pressing the home button) the WIFI symbol is either shown and then disappears or is already gone - but then after some seconds comes back and WIFI is on again.
Yes, i do have the setting for standby WIFI on always, so this should not happen.
Does anyone have an idea what could be the problem here?
Also i do have a fritz.box 7390 which supports a 5GHZ network - does the I9000 support a 5GHZ wifi? Maybe it's the router that's causing the issue an switching to the 5GHZ might fix it - but so far i could not see the network when it's on 5GHZ.. So i guess it's not supported but thought i might ask anyways...
Thanks!
