[Q] Annoying wifi deactivation

Hi,
when I am downloading a large file, my screen turns off after some time when I do nothing. So far so good. But when I resume to my Android I must see that the Wifi-connection was turned off, too - I think because of battery power saving.
But it was turned off during my file download, so I have to download it again and I have to keep my screen not to turn off by tapping on it periodically. That's what is annyoing me.
I recognized that the connection is not deactivated directly after the screen was turned off. It lasts some time (minutes?) then the wifi connection is turned off, too.
Is there a way to prevent the deacitivation of the wifi connection when the screen is turned off?
Thanks for your answers.

Yes,
Goto settings>wireless connections>wifi adjustments
There you should find an option for WiFi selection politics. Just choose not to never disconnect.
Cheers

Hmm, it is already set to "Never disconnect".
I think this setting is only useful when you want to switch automatically between mobile data (GPRS/UTMS) and WiFi.

No. That happens whether you want it or not if you have a wifi access.
Or I have a couple of busted phones at home that totally ignore this setting.

Tell your screen to never shut off, then change back.

A500 First day of ownership thoughts...

so after a couple of months of reading reviews and post by owners, i decided to pull the trigger last night.
after a 3-4 hour charge, i jumped right into it.
+very fast boot up.
i played with Honeycomb 3.0 before updating it to 3.1. i noticed that 3.1 had bootup & keyboard sounds, while 3.0 had none.
+the chassis is really nice. i loved the look. reminds me of my HTC HD2. rock solid.
+YouTube plays nice. i can already tell that i'm gonna be using this for mainly YouTube. but it really sucks that some videos won't play because it considers the A500 a "mobile device".
+web browsing is good so far. it even ran southparkstudios.com
uhm...that's all i can think of right now for pluses...
...and here's my cons with the tablet:
-it loses wireless connection when the screen goes to "sleep". but this apparently is a VERY common bug and issue with A500 owners. very annoying that i have to restart the wireless to get connection back. this is the main issue i have with it so far. my phone doesn't lose connection to the internet with the screen goes to "sleep".
-there's a dead pixel, but that's easily fixed by exchanging it for a new unit.
-lots of my games that i would normally use on my phone are completely useless because it still maintains a phone sized image. OR it just force closes.
-No Netflix app. although i read somewhere on the internet that there's supposed to be an official Netflix app coming out. but there's no way to confirm the validity of that statement.
-No Hulu
-No dedicated Facebook App
i still have lots to try out still like the HDMI out, the functionality of the USB ports, Divx/MPG/Avi compatibility, and MP3 sound quality. plus i want to see if i can install an NES/SNES emulator and play it via a bluetooth gamepad.
i noticed there's LOTS of ports...which means more possibly entry points for dust. which can be bad. ACER (or someone else) should make plastic/rubber port bootcovers to remedy that.
i haven't tried to install a custom ROM. nor have i tried to root it.
i'm looking forward to the 3.2 update. i'm hoping that'll fix all (or at least some) of the cons.

As for the internet connection, mine with stock rooted US rom (.13) doesn't do that. I have always internet after sleeping.
For the phone apps no scaling you can use Spare Parts and uncheck the compatibility box.
Facebook you can side load it, it works nice on my tablet.
Hulu is a common problem with all the tablets, you need a fixed flashplayer apk.
Hope it helps you

Root the device, for now try virtuous Xoom with 3.2 honeycomb. Once rooted netflix is fairly easily installed. Also, you can set the browser as "desktop". Mine has never lost wifi for any reason other than range.

My a500 have never lost WiFi during sleep.
There is a Tablet app "Friend Me" for Facebook and it is very good!
"Spare Parts" with "compatibility mode" disabled will make all apps full screen!
Never had a problem with a game (except those made or specific hardware)
Hulu and Netflics I can't comment! Living in Europe!

+1 to that - this is not a bug, this is a setting you can change, and is documented in your user manual.
Click apps. Settings. Choose the "wireless and network" menu. Click wifi settings. Click "Wifi disconnect policy" and modify it.
"Bug" fixed.

yikes i almost forgot about netflix
Netflix works great on the a500 - you need to root via Iconiaroot (assuming you are using 3.1) and then simply follow the instructions located here - http://forum.xda-developers.com/showthread.php?t=1076150
Just follow the instructions - either use root explorer with system mounted r/w or snag Acer recovery installer from market, install cwm, apply the patch.zip and you are done. Netflix looks great on a 10.1

hmm... seems like the consensus is that everyone doesn't have that issue. maybe my situation was a one time only thing.
but let me explain to you what i was doing when it happened:
i got tired of the Market app on the A500. but i'm also tired of the Market app on my HD2 as well. the new updated Market doesn't show you everything, it just shows you like the top ten for every category. anyways... so i put the tablet down (i didn't turn it off or put it in stand-by) and sat in front of my desktop and used the web browser version of Market. i probably spent about 15 minutes or so sending apps to install onto my device. when i went back to check on the tablet, the screen was off. i pressed the power button to bring the screen back on and the Wi-Fi was showing that it was 'OFF'. the only way to bring it back was to restart the Wi-Fi.
so yeah... it was strange. but like i said, maybe it was a one time event.
maybe i'll just set the timeout for higher like 60 mins.

Nope.
You issue is a result of your settings. If you want your a500 to keep a active wifi connection while the screen is sleeping, you will need to go into your settings menu and tell your a500 to not drop the connection while the screen is off.

ahhh... cool. i'll definitely be playing with the settings tonight then. thanks.

Wifi is my only complaint so far and I am experiencing the same thing. Mine is set to never disconnect wifi, and it doesn't. It shows wifi connected the whole day under battery usage. However, when the screen goes off it seems to drop the wifi and I must disconnect/reconnect to get it working again when I turn it on. Not every time but it is frequent.
To be clear:
When I turn the screen on, wifi is unusable until I go into settings and toggle it off and back on.

Are your wifi settings -> wifi disconnect settings set to not drop the connection when screen is off? Screen set to never sleep will not keep a inactive wifi connection alive - you need to go into wifi and networks catagory of settings and modify the disconnect policy.

Yes I know, sorry I meant never disconnect wifi not sleep.

I am confused.
Are you saying you have wifi disconnect policy set to "Never disconnect", but are having issues holding a wifi connection after turning the screen off?
Please provide more information, very hard to troubleshoot something this vague.

There is a difference between WiFi turning off and WiFi disconnecting.
Here is what I'm seeing on mine:
1) With my tab on, WiFi connected, browser working, I can ping my tab from my desktop.
2) Shut down browser, put tab to sleep, wait an unknown timeframe (lets say 15 minutes).
3) Wake tab, see WiFi is still connected, do nothing else. Start pings from desktop in a continuious loop, pings all fail, despite WiFi connected on tab.
4) Start browser on tab, browser connects to test website, and suddenly pings respond on desktop.
So, it appears that while the WiFi on the tab stays connected, it does not actually go 'active' and start handling data until an app needs it, such as the browser.

No shortage of apps that can work around this - I don't understand why you want a network connection when nothing is using it, but to each their own
https://market.android.com/search?q=wifi+keep+alive&so=1&c=apps

The wifi issue you describe is not a bug. It is an android feature to reduce battery drain. If an app or connection is not in use, it is cached until a process is called.then the wifi connection becomes active. You can disable wifi sleep policy but you will see a battery drain if you set it that way.
Remember the two most important parts of a tablet are the screen and the battery. A poor screen or poor battery life will kill sales for that tab faster than apple can draw up a lawsuit.

Well described.
Not sure why a user would want to bypass this - the moment an app requests data, as long as wifi disco policy is set - network connection is set to active.

Untrue. I have used a number of applications that when launched, do not 'activate' the connected WiFi. Two for example, 'QuickSSHd', which is a SFTP and SSH server, and 'IP Webcam' a webcam server.
Wake up the Tablet, and see that the WiFi shows a connection. Fire up either of these server applications, and try to connect to them. No go...
Now go fire up the browser, which of course makes an 'outbound' connection, the WiFi 'activates' at that time, and suddenly both of the aforementioned server applications can be connected to.
In other words, when the 'conected' WiFi is asleep, it takes an 'outbound' app to wake up the wifi. An app that is waiting for an incoming connection never sees one until an outbound app wakes up the wifi.
NOTE: This behavior is NOT seen on my Android Gingerbread phone, running the same apps with the same sleep settings.

It is not the video seeing the tablet as a mobile device.
It is your settings.
You can fix it very easily.
2 things to do.
open your browser
in the URL window (address bar) type about:debug and hit enter
it seems nothing happens but it adds a debug in settings
Next
On the very top right click the 4 lines with an arrow.
Click settings and on the left side click "advanced"
click "Viewing Mode" and set it to "desktop.
Now on the left click debug
click UAString and click desktop.
That's it.
Make sure you haven't saved any bookmarks from the mobile sites or they will still open from the bookmark as mobile sites.

Wifi issues?

After I got the touchwiz update and the second smaller one my wifi is messed up. It doesn't stay connected once the tablet is left alone for a couple hours. The signal strength color turns to white instead of blue when it does this. To remedy I have to turn the wifi on and off on the tab. Anyone else with this issue?

I am not seeing this issue. Have you tried a factory reset yet?

check to see if you have wifi set to never sleep (in advances settings). i had similar issues and setting it to never turn off worked for me. no battery drain issues with that setting either.

Thats bugging me too. Not always but from time to time I see "No internet connection" when the tablet is left alone. Before the updates I never had this. The other issue is wifi roaming. To get connected again I have to push power button, sometimes unlock screen, even sometimes it waits until the wifi settings screen. Dumb!

Ya I have it set to never turn off. I would hate to have to factory reset it and lose all my settings and Apps got a ton of stuff on this bad boy.

Apps are easily re-downloadable. If you're rooted then install Titanium Backup and back up all your apps with settings.

Do you have aan older router? I have the same problem (I have to turn wifi on/off if I leave the tab alone for 20+ min) but only at my office where my router is a bit older. At home with my brand new Linksys I have no issues.
My wifi is set to never sleep btw...

[Q] Lollipop WiFi issues - takes long time to turn on or not turning on at all

I had CM11 on my Nexus 4 and did a full wipe, then flashed the official Lollipop image (using flash-all.sh script). The process went smooth, without any problems.
Now, I am having WiFi issues. When I turn on WiFi from quick settings it changes the icon, but doesn't connect to the network yet. If I try to access WiFi settings it opens them up, but I can see only the actionbar and a blank white screen. No networks shown. Sometimes I even get "The app is not responding dialog". It sits like this for about 30-60 seconds and after that it connects to the network and I am able to access WiFi settings.
Sometimes I can't turn WiFi on at all. Quick settings don't change the WiFi icon to the ON state. If I try to turn it on from the Settings, the switch does literally nothing - not even "Turning WiFi on..." shows up.
I tried to reflash the system - still get these issues. Tried reflashing just the radio module - didn't fix it. No idea what to do. KitKat worked just fine.
Does anyone else have similar problems?

Same issues, but on a Nexus 10.
I have exactly the same issues as you, but on a Nexus 10. Running LRX21P 5.0 Lollipop.

+1
I used Wugfresh 1.9.6
Downloaded and installed LRX21T
Did a complete wipe (cache and factory reset)
Did a selective restore of ~75 apps from Google backup
Played with the machine for hours.
Rebooted, now got no wifi
Anyone suggest a workaround?
EDIT: I came across this post in the Nexus 5 Thread , where he suggests changing your router's channel to something below 12. I changed mine from 13 to 8 and now wifi seems to be working.
EDIT2: Sadly the above was a red herring. The problem seems more complex. Hopefully Google will release a fix soon

I don't think my problem depends on the available WiFi networks. But thanks for the response.

I have the exact same issues, Wifi doesn't turn on at all. It doesn't matter if I press the quick settings button or the button in the menu. It says Wifi on, but nothing happens. After the screen goes dark, Wifi turned itself off again.
Any suggestions? Thank you!

I'm having the exact same issue. Wiped with ADB and flashed LRX21T factory image from Google's website. No error codes during flash.
Wifi is great - if you leave it on all the time. As soon as it turns off, it will NOT turn on. I get no error message, no timeout like it usually does when Wifi isn't working properly, no crash report. Nothing. Just a stalled Wifi acting like it's turning on. If I exit Wifi settings page, and come back, it shows as being off. Turn it on, and it just hangs the same way.
So frustrating.
It's for sure not the network I'm on, as it also doesn't turn on when I'm not near Wifi, or when I'm at a friend's house. Rebooting the phones makes the Wifi work again...until it turns off for ANY reason. Then we're back at square 1.

I'm having this same issue...
My WiFi seems to turn itself off. Then there is no way I can get it to turn back on unless I reboot the phone.
Very frustrating.

I have the same issue.I sideloaded the OTA and everything went great,no errors during the installation.I was on stock 4.4.4.
When I turn on the Wifi it takes around 30 sec to connect to a network.If i click on the Wifi menu in the setting it usually freezes or I get a black screen.After that Wifi works fine,but another thing I noticed it doesn't remember new networks.I don't know if a factory reset would help...

Anyone find a solution yet? Did a factory reset eliminate the problem for somebody?

I got the same thing. Currently, I'm using Power Toggles to do the on/off setting.

I'm facing a different issue. Whether I have WiFi on or off, it always appears active in the battery usage stats ('scanning always available' is off)
WiFi was off when the screen was off from about 3 am to 2 pm.

I am having the same issue. very frustrating. it was working perfectly last night on my home network, but now it wont connect to my work network. it has the same issues as everyone else. the wifi toggle will turn on, but it will not show any networks. then after a couple of seconds it will turn itself off.

^^i am having that issue as well. the battery usage stat page is showing wifi as on even though it is off.

Have the same issue. After some standby time, turning Wifi on again, it showed me networks where I am not close to anymore and didn't show me the actual networks where I am right now. This seems to be a serious bug that needs fixing. I don't want to reboot my phone to fix it. Didn't Google delayed the Lollipop-Update because of some Wifi issues?

I have all the symptoms listed in this thread. I filed a bug report too: https://code.google.com/p/android/issues/detail?id=80028&q=LRX21T

Found this thread when this problem popped up for me after flashing the factory images one by one. Might try to find a source-built ROM using a later version to see if it got fixed.

Wifi not staying connected on Z300C - need to switch airplane mode on/off to restore

When I returned from a 2-week holiday last week I found that my Zenpad 10 Z300C had completely powered itself down, and required several attempts to hard reset it. It eventually started up, and went through a lengthy "optimising apps" stage, as if there had been a software update (but there were no other signs that there had been an update). My build number is LRX22G.WW_P023-V4.7.5-20160419044030548_201506300108.
Now it frequently disconnects from my wifi router - it won't stay connected for more than a few minutes at a time. The wifi icon in the notification bar changes to what looks like a small circular arrow (not dissimilar to a recycling icon). If I turn wifi on/off I see an "authentication problem" message next to the router's SSID in wifi settings. The only way I can restore the wifi connection is to turn airplane mode off/on.
Any idea how I might fix this??

Same lousy wifi
This is an fairly old post but no replies. I have been having this problem too ZenPad 10 P026. Even my crappiest model 3 iphone keeps the signal when I go from house to garage or even bedroom. Started about the same time as threadstarter. Is there firmware, unfirmware, or hardware to fix this. Will just drop the signal like hot potato. thanks

I have this problem too with a new Z301M . It is super annoying. Twice a day I have to reboot it to get the network to function properly.
