android os wakelock.. only when connected to home wifi.

i've had this issue since ive had my nexus 4 on 4.3 and now it continues with my nexus 5 on 4.4
When i'm connected to my home wifi, 'android OS' will show on my battery usage as the highest offender, causing the phone to stay awake 90% of the time. This doesn't happen when im at work on the wifi and also doesn't happen when on mobile data.
Any ideas on this? i'm been messing around with wifi settings but no luck. i have a router and a separate wifi access point at home. Could it be the router?
Thanks

Easy fix: Don't connect to home wifi! *lulz*
No really though, tried other ROMs? Could possibly be the router if it doesn't happen to other connections. What router is it?

I have not tried roms, its bone stock unrooted. I have a linksys wrt54g router(tomato) and a tplink wa901nd access point(stock firmware , tried openwrt with the same wakelock issues)
I'm thinking i might have to eliminate the access point to see if the issues goes away or not, then maybe replace the router.

Connect to them both individually, just see if the issue persists. Maybe the router is sending messages to Android?

Keep me posted, we'll sort it!

I think I'm getting this as well. If I'm connected to Wifi and leave my phone on standby it will drain 8-12% per hour, but if I leave it on mobile data it will drain only 0.5-1% per hour. I'm going to download BetterBatteryStats and see if I can find the process causing this.

wlan_rx_wake
A fairly common and problematic cause of this can be identified by wlan_rx_wake being the highest wakelock keeping the phone awake as seen in betterbatterystats or similar.
There is a great thread listing all the likely causes:
http://forum.xda-developers.com/showthread.php?t=2519294
But whether you can isolate which cause or whether you can do anything about it is another story. For me it eventually turned out to be traffic generated from Windows machine on my network, I followed the advice to Disable IPv6, IP Helper service, shell hardware detection service and the Windows Media Player Network Sharing Service on each Windows PC and my stay awake time from Android OS plummeted from hours to minutes which I can deal with.

I ended up assigning static IPs to both my nexus 7 and nexus 5 and the issue has been resolved.

Confirmed!

I saw this on xda portal and I can tell, that problem is resolved when setting PI from DHCP to Static.
At home I have both gadgets connected with manual IP for quite some time
Ended up with great battery life on Mahdi rom (N5)...

Internet connectivity problems

Hey guys,
I have a problem with my nexus, I've noticed that my internet on my phone is acting quite...strange to say. I have a dual band router(d-link 880l) and on my phone I only use the 5GHz one. it's the only device in my home that has problems.
The problem is that when searching something using the google bar it takes ages until I get the desired result, on youtube app sometimes when I open it ,it won't load anything,the second I close it and open it again it works,some videos just refuse to start until i restart the whole application, sometimes whatsapp doesn't connect to their server I have to restart the app to get messages, or to see las act of people,on facebook messenger is the same story,when i send a message it won't send ,it acts like I have no internet connection,until I restart the app. Ironically I get CONSTANT 81mb/s download and 91mb/s upload in speedtest.net app.
I really don't know what to do ,i've forgotten my network,tried connecting on 2.4GHz,put my wif i mode only in 2.4GHz,enterd recovery cleard cache partition,unninstaled whatsapp,youtube,fb messenger,google app,deleted all google play services data,restarted phone,neither of those fixed it...
Can you help me...?

Are you running the latest stock ROM or some other ROM/kernel combination?

I'm running rastapop 5.1.1 LMY48I with elementalx 4.04 since august 2015 with no fancy kernel settings or mods, just adblock and xposed over the top.I started to have this problem since november.
I did a factory reset on the router and I still have the problem.

To rule out software being the problem, I recommend flashing back to stock to see if the issue goes away.

I own a D-link DIR-850 (dual band AC router as well) and I am experiencing kind of the same problems. I have a Nexus 5 with latest firmware (MMB29S) but have had these issues for a while already. My girlfriends HTC One mini suffers from these problems as well. Most annoying is the seemingly random disconnects from whatsapp, I guess caused by Google Play Services being unreachable as at that same time also the Play store and other services relying on it are unreachable. Not sure whether this is an Android bug or caused by a bug in the Dlink router, which off course has been reset to factory defaults and checked for updates several times
Strange thing is that at the times that the Play Services are unreachable, other (plain internet based) services such as browsing with Chrome are working just fine.

I did some research on this compatibility issue between an android phone and a d-link router after I discoverd I'm not the only one.
The problem turned out to be some bug that is present in a way or another in android since lollipop , I think that lollipop(my case) is getting stuck when trying to do a DNS lookup ,but the problem is that it only happens on my home network, I don't have any problems at my friends wi fi or a public one. So my router isn't playing well with lollipop or the other way around.
The only solution I found to this problem is to disable ipv6 on your router or on the phone. So I did ,made a script that changes a value in a file, here it is : "echo 1 > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6". With this I disabled ipv6 protocols on my phone(i've verified "disable_ipv6" file just to be sure that the value is "1") . Everyone bragged about it that it sloved their problem. Well guess I'm not that lucky,the problem still persists on my phone...
I've tried everything in the book...guess that this brand new 150 dollar router is not that impressive as they say...
I don't really want to factory restore my phone,I want to be my last option...the guy above me said that it did the factory reset thing and it didn't work so guess that it isn't an option after all...
If someone can help me(us), i will be very pleased...

At my workplace we have an Asus RT66NU providing the wifi, where I have never had any problem with this.
As you are suspecting it has something to do with the ipv6 stuff, I'll be experimenting with this a bit to see if something changes. First test is putting the autoconfiguration setting to SLAAC+stateless DHCP.
Next step will be disabling ipv6 at all.

I tried with PPPoE( my internet connection ) on ipv6 that is shared with my ipv4 session with SLAAC + stateless DHCP and stateful DHCPv6 . At first it was promising but in the end it didn't really solve my problem. Just for the record ,I had my ipv6 settings before on local connectivity only .

Both WiFi and mobile data aren't working

Since this morning, both my WiFi and my mobile data (LTE) do not work. Both show the "!" symbol next to it. Tried turning off wifi, enabling flight-mode and disabling it again, turn off the device and everything.
I know my local internet is working since I'm currently posting this thread with it.
I have honestly no idea what's causing it and how to fix it

Both now work again. I did absolutely nothing and still have no idea what caused it
Edit: it kinda works but is super slow
Edit 2: Not working again, maybe the internet connection is so slow that android thinks its not there?

Perhaps your DNS server was down for a bit if you set a custom one. People on the reddit were facing the same thing. I don't recall the exact DNS I think it was AdGuard or something. But yeah.

Yup, thats totally it. Completely forgot that I had that DNS enabled

WiFi Problems with Android 11 (GrapheneOS)

I'm having problems with the WiFi connection since I updated to Android 11. I'm using GrapheneOS with Netguard. Before updating everything was working just fine. Any ideas?

i am having the same problem with my pixel 3 also. i am using stock android 11. it was fine before updating the phone to android 11 stable version.
this problem occurs when i connect with my wifi . it works so slow and sometimes youtube gmail twitter facebook feed dont even refresh .
bt when i use the same wifi using my laptops hotspot then connct with phone it works fine.
i tried roll back to android 10 but didnt work and also tried custom rom didnt work.
yesterday used 1.1.1.1 vpn app with wifi then it workd but still slow.
is there any solution for this?
this problem is so much annoying.

Okay, I found a workaround for my problem:
If I choose static IP instead of DHCP when setting up the WiFi it works without a problem.
Not sure why this is the case.

i tried it but still same problem ((

I can't find the reference now, but ppl had some similar problems when 10 came out and they had to reset all network related stuff and it worked for some... maybe you should try that... it will delete all your stored wifi and passwords...

To my problem: I flashed a new ROM and the problem still remains. So I think it's not related. But thanks for the hint.

WiFi slow response after EMUI11[update: reason found]

Hi everyone,
So I updated my p40 pro (GMS installed) to EMUI11 last week via OTA.
I noticed that after the update the wifi response is not good, i.e. many apps that I use are slow in the initial loading of content (internet based like ebay, etc). After that, they somehow work better. I checked in various WIFI networks and getting the same result, so I suppose that it is the update to blame. All apps load immediately in mobile data, so this also confirms the wifi issue for me.
I remember having a similar problem the first time i got the device and loaded GMS, but after the second time the problem was gone.
Tried wiping cache but no dice.
Anyone noticing the above in their devices? Any tips?
cheers,
t

Anyone?

For users experiencing the same issue I noticed foll:
After some messing around I reset network settings and after restart the phone WiFi connection is snappy again.
What I notice though is that in case I unfreeze gsf and then re-freeze it, the problem incurs again, so surely something is happening at that point; I then have to once again reset network settings so that it does not lag.

OK, so I finally found the culprit of the sh*tty Wi-Fi after the update to EMUI11:
There is a software bug for sure, due to which by the time that you enable WiFi calling on the device, all apps are slow to load content(besides the browser and social apps which work OK).
I have been constantly resetting network settings to fix the issue, issue was fixed but as soon as I enabled WiFi calling, things started to get problematic.
After switching WiFi calling off, problem immediately disappears, so surely this is a bug which was not present in previous firmwares.

Thanks for updating your thread! I had the same issue with some apps, but not all of them. Also, I was able to use these apps on Wifi using a VPN connection. After disabling Wifi calling the problem disappeared. The issue occurred after updating to EMUI 11.
I wonder why there aren't more people complaining about that.

Honestly? I have no idea, but it is a really sh*tty bug for me, since I have been using WiFi calling for a long time (network reception in my home is bad). I hope Huawei or even some dev finds a fix soon..
Today i updated firmware to 168 but the problem still persists.
Another thing I noticed though is that you do not have to fully switch off WiFi calling, but only not to set it in WiFi preferred, instead leave it to mobile network preferred. The caveat tho is that when you have it in mobile network preferred, even if you have 1 bar of signal it will rarely switch to WiFi calling, so it is pointless.

OK, I think that the emui 11 update has ruined the phone due to this WiFi calling problem. It is almost unusable, every phonecall in my house ends up in call dropping, so the update got me in a position to either set wifi preferred in WiFi calling and have most of the apps lagging like hell, or to set it to mobile preferred and have usable apps but dropped calls all the time.
What a mess.

Indeed, thanks a lot for updating your thread!
The downloading lag I had on many apps (Gmail...) was driving me crazy!!
I disabled wifi calling (I couldn't until now, as I didn't have any reception in my old house) and downloads work again smoothly!
(I'm on 11.0.0.168)

hi i have the same exact problem you have described, and possibly started after i upgraded to EMUI 11.0 as well, but i havent noticed before. Most of the apps are lagging like hell and most of the times i end up switching to mobile data as it seems faster (though i have 300 mbps wifi connection). Let me try disabling Wifi calling and see if this helps with the issue.

Yes it indeed helped now.. Apps load much faster after disabling wi-fi calling. Guess we need to raise this as bug with Huawei.

If you know the way, yes... I personally raised this issue to Huawei support hotline a few days after the update, but I never heard from them again.

oh my god, i resetted my phone and re-googlefierd it now 4 times until i found out those problems are just "wifi-calling" related.
problem still persists on latest 11.0.0.196
was anybody able to fix this?

I guess not, unfortunately the only solution for me was to switch wifi calling off. personally I switched to S21 ultra. Even though I believe that overall it was a downgrade move, god I was so frustrated not being able to use WiFi calling at my home, so this was the main reason of me switching to S21 Ultra. I still have the p40 pro sitting in a drawer, hoping that someone may fix this at some point I really miss the epic low light cameras and it's form factor (s21u too big for my taste and also when taking photos at night it's shyte compared to p40 pro)

Omg, thank you. It has been bothering me for months. Normally I just turn off and on wifi, to get the apps to have axcess to internet when I need to. But normally the have trouble again after short time. But now after setting it to 'operator preffered' and not 'wifi-preffered', it works like a charm. Ofcourse I do not have problems with the operator-signals...
But thanx again

Thank you so, so much! This was driving me nuts. You made my phone usable again

Seems like the Problem got fixed somehow silently.... im now on 11.0.0.223 & Updated all huawei apps to latest, and VoWifi seems to work fine now, at least for me...
can anyone confirm ?

My p40 pro is currently sitting at my drawer since I bought a S21U, but I will check to see if it works.
