[Q] Dropping wifi

Has anyone had any wifi problems, mine was OK yesterday but today it drops the wifi but then joins back as soon as I click the wifi in the notification bar. I'm just thinking if its because my battery is low or is it a common problem.

I've had this issue with a speedtouch router, but didn't have it with a netgear DG834
Does it have full signal?

Yes its full but then just drops altogether. I have charged it now and seems to be OK so not sure if it was because of low bat or mabee just a hiccup

Go to your wireless setting and then click Wi-Fi disconnect policy.
Set it to "never disconnect". You can also set it to Never while plugged in if you have the cable connected. Some routers will have trouble auto-negotiating if your device has a sleep/disconnect policy set.
That or it's some other weird issue like a low battery/wi-fi issue like you said.

I had this happen once while I was using the touchpad to scroll down a website. Was anyone also using the dock touchpad when it happened? I thought I found a gesture that turns off the WiFi. Of course, this has only happened once in about 10 hours of use.

I had a similar issue and the new firmware released today fixed it for me.

I am 3.1 and not root but my Wifi keep droping off once in a while when the tab in sleeping mode. I set it to never disconnect and have to reboot because it kept scanning and wouldn't find it till reboot. Any suggestion?

I have dropping wifi issue, and i had to disconnect and connect again without rebooting. This happened since 3.1 update. I think this may be caused by decrease in wifi driver version.
I also posted this issue on another thread (issue with 3.1) and hopefully ASUS rep will see and fix this issue.

Since 3.1 I am also having this issue and its pissing me off Hope for a fix soon.

Now I'm having wifi issues as well... My wifi will automatically turn off... When I tried to re-enable wifi, the wifi setting will say "turning off" and grey out... Only way to recover was to power cycle..
Now I'm starting to worry about 3.1 update... I wish that I can downgrade to 3.0.1 without any major force close issues.

my gf has this issue with her tablet resuming from sleep mode, just throw it in airplane mode, wait 5 secs n turn off airplane mode.

This new-with-3.1 issue has been mentioned in a couple of other threads.
Now... if only we noobs had a clear way of reporting significant bugs (like this!) to the appropriate folks at ASUS.

Yes I have been having the same problem. Just started today.

same to me~~ the wifi keeps dropping randomly, I want a fix!!!

Me too

Ever since 3.1 update, I too have problems with wifi disconnecting. Seems to happen most often after I wake from sleep. I have the wifi set to stay on all the time, doesn't help. After waking from sleep, flipping the wifi off (airplane mode) and on again seems to fix the problem.

i'm havig the same issue,wifi drops, when the tablet is sleeping, I have to discoonnect, then connect again to get it working. Wifi speed also seems slower with 3.1.

Possible Fix
While fiddling with my router I just made the discovery that when changing the channel to 12 or 13, the signal dropped out. Channels 1-11 worked fine. When set to 'auto' detect the signal occasionally drops out. I assume that when on auto it is occasionally accessing channels 12+13 and that is the cause of the problem. So for those having wifi signal problems try setting up a specific channel in your router settings and see if it makes any difference for you. I hadn't any problems before the 3.1 update, but Asus seem to have rolled back the wifi driver, and I guess this has affected a fair few users.
My device is running stock 3.1, never fiddled with the system in terms of rooting, ever. It's a WW sku device.
Obviously this shouldn't happen. And most likely wont affect US users as they don't have these channels. It may not be a fix for you but hopefully it will help someone running a non US build.

Problem with WiFi after latest Note 4 update

Hello All,
So a few days ago I received an update with Baseband Version N910CXXU1DPI1
After the update completed and the device restarted, I noticed the wifi keeps going on and off on and off if it's not connected to a wifi network. I went to the wifi settings to make sure if any other wifi settings in the advanced menu are ticked and found that nothing is ticked which is good.
The problem disappears only if I restart the phone. Is this a common problem with this update or is it just me?
Thanks

Hi me too, I have similar problem after update to N910UZZH2DPJ2.
When I turn off wifi, the wifi icon in the notification toggle switch on and off automatically, i.e. turn green and grey automatically.
When I go into wifi settings, the switch also turn on and off automatcally non-stop.
They will stop when I connected to wifi.
I have already do a factory reset, it doesn't fix the problem. Any idea how to solve it? Thanks!

I think someone needs to report this to Samsung....I would do so but I'm not sure how. Let's just hope for a small patch that will fix this issue..it's very annoying

Yeah me too, Wiped the cache and still nothing. Wifi keeps randomly restarting off and on until i restart. But the problem comes back after restart................... Can someone Please help us all....

Thanks for the feedback guys. Glad I'm not the only one with this problem. I think I might just flash with Odin to the previous version, or if someone can help us that would be greatly appreciated.
Is there a way we can report this bug to Samsung?

I'm having this issue also. Is this why I'm seeing lots of posts about folk downgrading to 5.1.1; issues with the 6.0.1 roms/basebands? Before I updated my firmware I had the issue reported by another user on here where my WiFi kept turning off immediately after I tried turning it on.

I never had an issue with Marshmallow except for this random wifi on off issue in the latest update. Been on stock rom since I got my phone back in December 2014 !!!

Hey everyone I was able to temporarily fix this issue by turning off wifi scanning in (Settings > Location > Improve Accuracy). I heard somewhere on here it might have been a recent app update that is causing the issue.

Thanks for the tip 93_teg. Going to give this a try and report back.

@93_teg I did your solution and so far it seems to be working. No more Random wifi on off issue, let's hope.
Thanks for the help

@93_teg thank you so much for sorting this out it switches off now without restarting :good::good:

Thank you for the fix, I spent waaaaay too long troubleshooting this issue. I think the next step on my list was sacrificing a lamb but this works too

today's update(N910F PHN) didn't fix it.
it's probably the latest Google play services update that caused it, it received an update shortly after the October security update.

Probably, I seem to have had the issue start same time as everyone else here, and I'm on the t mobile version N910-T, and my last OS update was October 1st

I appreciate your solution, I'd working for me, i start to feel crazy, and I want to sell the phone, but I don't, thanks, sorry by my english

I received an update on my phone yesterday but have Postponed it...going to see whether it fixes the issue or not.
Thanks to all who participated in the thread...greatly appreciated

Workaround
Hello,
I confirm that the issue is due by the Service Google play. The workaround, to stop the Wifi is blinking, is :
Parameters > Applications Manager > choose system applications (Three dots) > select Service Google Play > Stop forced (and possible Stockage and clear cache).
This workaround works after each use of the WiFi.
And now wait a solution from Google (and Samsung may be).
Thanks

Delayed notifications on V20 - help!

Hey all,
Struggling with my V20. I've had it since launch and never had a single issue like this prior. I first started experiencing issues with no notifications showing up on my phone, unless I went into the app (hangouts, gmail, work email, etc.), when I traveled to the west coast (which caused a time change) about two weeks ago. As soon as I came back to EST, everything was working for ... a day. Notifications stopped working again.
So I factory reset my phone and things were better, but still not perfect. Regularly not getting notifications between my primary applications (good for enterprise, gmail, hangouts and google voice). The issue appears to be more so when on WiFi. As soon as I change to cellular I get MOST of my notifications (not all).
I installed Push Notifications which seemed to initially help, but thereafter, no dice. I'm not using any battery saving apps either.
I'm at a loss. What am I doing wrong/missing that I'm having all these issues?
Thanks

I had the same issue. I contacted T-Mobile about it, and the problem seemed to just go away, so it could have been a network problem. However, I also rolled back SuperSU from 2.82 to the 2.79 SR3 by flashing it in TWRP. You should try that and prevent SuperSU from upgrading in the Play Store.

Thanks for the response; however, I'm not rooted.

Now that you mention it, I have had the issue recently as well. I will open snap chat and have snaps or hangouts and have messages. I do not have any kind of battery saver on or block apps from sending notifications. I am on ATT.

I have a friend who's having this exact same issue. He's on the 14B update from Verizon. We're thinking of trying a factory data reset to see if it solves the issue.

Yup. I got the same problem. Unlocked, on Verizon.
LG phones have always seemed to have this issue. This phone, my G5, G4... Annoying

I think I may have found a fix for it. I'll post a YouTube later.

I know Gmail has had its own issue with notifications that is not related to the phone. Many users including myself get delayed Gmail notifications or not at all. There is a bug tracker on the forum that Google states they apparently fixed but people still complain. It is frustrating.

I'm noticing that the Google app is causing delayed push notifications on all apps for me. I am able to reproduce the delay when connecting bluetooth devices (you may even notice it takes ~10 seconds for the bluetooth connection notification to show up on the secondary screen). I'm seeing the issue go away if you disable the Google app. I'm curious to see if this fixes the delay for other people. Try freezing/disabling the Google app.
I've been using Push Notification Tester where I'm able to see some heavy delays in push notifications being received. Specifically with Bluetooth connect events so far. I found the culprit to be the Google app by watching logs (logcat) and seeing reports that the app is processing events for 10 seconds per event which blocks the queue. If I continuously connect/disconnect bluetooth devices I will see push messages fail to be received for a long time (10 seconds for each bluetooth event adds up....)
If you're only experiencing issues with a specific app this might not be the the same issue. Worth noting I was able to reproduce this issue with a Galaxy S8. Figure I'd just share my findings.

I just disabled my google app, and it seems to have fixed the problem almost immediately. The bluetooth connection notification comes up on the second screen almost immediately, and goes away after a few seconds. Before disabling the app it would take up to 20 seconds to just show up on the screen, and then it would never go away.
Now to figure out why the app is doing it...

So, upon restarting my phone, these notifications (along with 20+ others) finally came through. Appears the only way I can get notifications is as follows:
1) Switch from WiFi to cellular, or vice versa, or Airplane mode - some notifications come through
2) Forcing a manual refresh while within an app
3) Restart the phone
I'm going bananas over here. Ready to smash this thing. I don't understand why doing a factory reset didn't fix this issue.
Help!

FWIW, called VZW, they have absolutely no idea.

By disabling the Google app, this simply rolls back the version of it. Is that you've found to be successful?

I do want to say that this issue is only happening on a recent release of the Google app since I suddenly started noticing this problem one day.
Therefore, rolling the Google app back may solve the problem, but I can't be for sure. You most likely won't be able to disable the Google app via the standard interface. You would need to be rooted and disable/freeze it with an app such as Titanium Backup or 3C System Tuner.
If you want to continue to use the Google app, you can get more advanced and specifically disable the receiver that the Google app is using to intercept the events. Note, though, that this may have side effects on the app, but I have yet to notice any issues. Using 3C System Tuner you can disable the "com.google.android.apps.gsa.broadcastreceiver.CommonBroadcastReceiver" receiver which is what is intercepting and delaying the events/notifications.
App Manager -> Apps -> Google App -> Manage -> Open.. -> Details -> Receivers -> Uncheck "com.google.android.apps.gsa.broadcastreceiver.CommonBroadcastReceiver"
https://i.imgur.com/zerTmWq.jpg
Just be careful using this app as it allows you to change many things.
Here is the logcat message I noticed which was causing the delays. You'll notice it saying the CommonBroadcastReceiver consumed 10011 ms (10 seconds) while processing the android.bluetooth.device.action.UUID broadcast record which is fired when connecting/discovering a bluetooth device. This is why it would take 10 seconds before the event hit the 2nd screen.
Code:
06-21 19:29:27.496 1554 2993 W BroadcastQueue: ResolveInfo{99f8ba4 com.google.android.googlequicksearchbox/com.google.android.apps.gsa.broadcastreceiver.CommonBroadcastReceiver m=0x108000} consumed 10011 ms for handling BroadcastRecord{a529d0d u0 android.bluetooth.device.action.UUID} in background queue

When I disabled Google, it rolled back the version and for the past couple hours, all notifications have been working perfectly. Let's see what the next couple days bring.

My US996 unlocked V20 has been getting progressively worse on bluetooth connections the last couple of months. After waiting and waiting for LG to update the phone, I decided to unlock and root recently. I am still on a stock rom, but at least I have options now.
Using 3C System Tuner to disable CommonBroadcastReceiver as you have shown has been the greatest help of anything I have done. This info could easily merit it's own thread under "V20 bluetooth connection issues".
Before applying your work-around my phones bluetooth connections would become less and less consistent, slow to connect, fail to connect, stuck secondary screen connect notifications, and require frequent reboots to connect to my vehicle.
After disabling CommonBroadcastReceiver, connections are quick and mostly reliable, no stuck secondary screen notifications.
I believe the blame for these problems lies with LG and their lack of attention to google android updates. Google might have fixed these issues 6 months ago and LG has not done anything about it. My US996 was last updated December of 2016, LG said they have no update scheduled for my phone. No security updates, no android updates.
Thanks again for this work-around!

ive had this issue going on for a few months now. how does the google app affect text notifications? this is so frustrating and i am on call for work and i am missing notifications in the middle of the night.

Limited network throughput

I just noticed that my network throughput is limited when doing speed test. Can't go above 10mb. This is on wifi or mobile data.
I have a second ph1 and it gets 25mb on wifi no problem.
I reset my network, but the issue is the same. Also restated.
I think full phone reset can fix the issue but I don't want to go to nuclear option.
Phone is stock on the April update.
Any ideas welcome.

For those interested.
Disabling and enabling the Developer Options resolved the issue.
Also cool feature is safeboot. Press and hold the Power Off message on the power button menu.

Just wanted to confirm I had a similar issue but didn't realize it until you said something.
though for mine it was like that out of the box and ironically the update to 8.1 April build fixed it.
I was getting 25M at work (in Houston so lots of signal) after the update I'm getting 75M (On sprint)
I didn't notice it prior because my work wifi is limited to 10M and for LTE I read a lot about the antenna being an issue so I just accepted it.
its good to know if it happens again I can just enable and disable developer options.

App Battery Optimization resetting after reboot?

There are are a few apps that I set to be "NOT OPTIMIZED" such as wear OS and Nest. Lately I've noticed that apps that are set to this setting are reset back to OPTIMIZED after a reboot of the phone. I tried to see if this behavior is on my Pixel XL 2 but the settings stick after a reboot on the Pixel. Is anyone else experiencing this on their OnePlus?

Yes, I am experiencing this as well. I thought I was going crazy. I use the Nine email app for work and after every reset it tells me that the app is not set to be used the background for syncing. I just set a bunch of apps to not optimize to be sure, and upon restart my 'not optimized' list is empty.

I'm having the same issue with Wear OS. Every reboot I have to set to Not Optimize

I posted in the OnePlus community and support contacted me to get a log file but it's 69mb. They asked me to email but i can't. I'm waiting for their response.

Yes, 5t and 5 as well. Problem here is for me and a lot of other people, they are using apps like Plus Beat to get notifications since OP idiotically removed the notification light, and those apps need optimization turned off to work. It's not a hard fix to go unselect it again but it shouldnt be happening regardless.

This is now happening WITHOUT rebooting the phone. How do we fix this?? Plus beat us constantly being overwritten to optimize battery when I turned it off.

Same here

Same thing here. I did find that the reset happens after reboot. If you restart and go straight to battery to look at your app optimization, everything will be fine. Then wait 30 seconds or so and everything will have been reset to "Optimize." Super frustrating.

It is a know issue and Oneplus has this set this way on purpose. We can only help enough of us complained to Oneplus and this gets changed on some future update.

Battery optimization see more list on free software download site it will open your device and see the the problem.

This issue and the microphone/ audio issue pushed me back to my Pixel. Add to that a weird issue with tune in radio where it keeps thinking it's offline when you launch it initially and takes a good 10 minutes to come back online and all that was a deal breaker. Factory reset did not fix these issues.

same here...
Seems fix turning off folowing.
I disable "deep optimization and" "sleep standby optimization"
Settings --> battery --> battery optimization --> 3 dots on upper right and then "Advanced Optimization"

Hmm... I went to try this out, but I don't have the 3 dots to get to the deep optimization and sleep standby optimization settings. I have the T-Mobile version of the phone.
This is incredible irritating! I rely on being able to get emails from work, and I keep finding the optimize setting reverted from "Don't Optimize" to "Optimize". At first I was blaming the app but have now come to the conclusion that it's the implementation of the Battery Optimization on this phone. Reboots definitely revert the setting, but I also suspect it gets reverted after some time without a reboot. I haven't really been keeping track until recently to confirm this.
