[UPDATE]Official Nexus one Wifi issue thread(every N1 owner should read)

Sorry I know this problem probably has been brought up many times. But here I just want to make a total one and collect all the feedbacks from N1 users regarding to the wifi sleep issue with N1.
Let's just make it simple: Every N1 owner PLEASE DO test out the wifi connection when your phone goes to sleep as there are MANY people suffering from this problem all over the world. Especially the later buyers since February this year, almost every phone is potential to this problem.
######################################################
Diagnosis:
1. Set the wifi sleep setting to "never" in the wifi advanced setting menu.
2. Turn on Last.fm app(or Pandora, but Last.fm is most effective and responsive one to test it out), leave the phone on wifi and turn off the phone screen or let it goes to sleep.
3. The symptom is the app will stop streaming shortly afterwards(with Pandora stops maybe after one song, for which I suggest everyone test it for at least 15 minutes). Also most likely you will stop getting any email notification or anything requires data connection. And you might not be able to ping your phone or the ping responses VERY slow as well.
######################################################
######################################################
Background:
This problem was recorded from earliest almost 6,7 months ago and has affected both AT&T and T-Mobile versions(with reports of the same issue on other versions sold outside US). So far, it's suspected that the problem mostly likely lies in the lower level architecture of the phone(either software or hardware) because the problem still exists even after people has replaced the stock ROM with the custom ROM. Another proof is that people get problem with brand new phone and also the replacement phone. Another note is the problem has been found both before FROYO update and after. At this moment, there's no official fix(some Google employee blatantly brushed the issue away and asked N1 users to get over it, check out the link below for original conversation) for this issue except a work around thanks to wifi fixer app developer.
######################################################
This issue is often times neglected by N1 users because usually people don't use the phone on wifi all the time or they simply switch between 3g and wifi. But for people who use wifi a lot or use VOIP, it could be a real deal breaker.
So here I just hope everybody could test your phone out and see if you have this issue or not. Please report how your result turns out in this thread. Also, for further and more detailed discussion and cases, please check this out:
http://www.google.com/support/forum...52&hl=en&fid=01a47ff5b0a92d5200048be07b6cb5c1
You are more than welcome to add your experience to the discussion above so hopefully it can wake google up.
####################################################
UPDATE:
So Broadcom just released a wifi driver fix several days ago which may solve this issue. According to the record, phones with non-zero MAC address suffer from problem.
The driver has been incorporated into the latest Cyanogenmod(either RC or nightly build). People are reporting it fixes the problem while in some other cases, the problem still exists even after the fix, even for people who's MAC address starts with 00.

Last.fm works fine with the screen off here, always has done. I even turned off mobile data to be sure it's not switching over to that.
This is with the wifi set to sleep with the screen off (ie. the default setting).

i've been using wifi fixer and since i installed it, i haven't had a single wifi disconnect on my home network(it seems to be a network dependent issue as i never have issues on other networks)

yeah, the point here is that many phones have the wifi sleep policy issue(doesn't work).

Indeed, however mine does, so this thread will need both sides of the argument

No problems on my Nexus One, running latest CM 6 nightly build.
I bought it couple months ago from eBay, so I'm not sure which shipment it is from.

Only issue I'm having after upgrading to Froyo is that my phone won't connect to my home network by itself when in range.
I have to go into Wifi Buddy and manually connect. This never happened on 2.1, but magically started after the FRF50 update, and never fixed itself in the next couple of builds.

I have always had this same issue! Maybe its something to do with my home wifi? I am yet to test it on froyo.
I am mostly connected to wifi with no sleep issue.

I have kind of the same issue at home, I recently replaced my wireless router, I never had problems connecting to the old one it would just stop broadcasting constantly but my N1 would always connect automatically. With the new router my N1 keeps saying the connection is disabled and I have to connect manually. This never happens at work, it always connect automatically so it seems to have something to do with the router settings but I have no idea what.

No problems here. Last.FM works fine for me on WiFi when screen is off. I also get notifications. Running FroYo rooted with locked bootloader

i am having the same problem, when i go out of range from my wireless and then back in range, the n1 just says scanning and never re-connects.
that said, using a channel lower than 11 on my router did seem to help with the sleep issue.

sorta, i never had the issue on any network besides my home one

I've also been having the disconnect problem with my N1. Maybe it would help if people whose sleep policy is actually working could post what wifi router/AP/whatever they are using. Also, if possible the first for identifiers of their MAC address. I read on one of the Google posts someone with a MAC address starting with 38:E7 having problems. The MAC for my phone is the same. For what it's worth I'm using a D-Link DIR-655 router and a Speedtouch 716 v5 WL and am experiencing the disconnect on both.

I've had the issue with 2 N1 tested on 3 different routers. I've read that it is related to the low power mode the N1 uses while sleeping not playing nice with routers. Not all N1 show the problem, apparently only the most recent ones. I've called google support and was told google knows about the issue and is working on it, but I am a bit cynical and I'll believe it when I see a fix.
Wifi-fixer fixed my problem only after I disabled Sipdroid which was interfering with it.
Mac adress: 38:E7: D8
I'll post my router model later when I get home.

It's weird because most of the time I don't have this problem. My WiFi stays connected all night long to WiFi. But once in a while it does disconnect and switch to 3g. I think its certain routers, because I didn't have this problem for first 3 months on my old router, now it happens with my new router.
My phone never has trouble reconnecting back to WiFi. Everyday when I come home from work, as I walk up my driveway the phone has already automatically connected to WiFi. I've made sure about this one since I read this problem all over.

I bought my Nexus One directly from Google when it came out for AT&T. It certainly has the wifi issue and it is very annoying. My expectation is that the phone jump on my wifi network when in range as all of my other phones have done. Instead I have to manually engage the phone to get on wifi. SUCKS!

this is the biggest problem for me with my n1.
although the wifi does stay awake, it slows right down..
if i ping my phone, the response time increases when the phone is asleep, but doesnt time out.
if i ftp a file from my laptop to my phone, the speed drops from 1mb/sec to 100kbps/sec when the phone is asleep.
i have found the app "fix my wifi" solves the problem of waking the phone after a few hours of sleep and finding the wifi has failed. if only there was a way of getting the speed to stay the same.

[Q] Verizon 3G vs. WiFi (problem)

On my Xoom, Verizon 3G kicks WiFi butt. This shouldn't be.
I thought maybe it's the WiFi network(s) I have been connecting to, but I have sampled a variety of networks including my home network with a very strong signal.
Quite a few 'time outs'. Symptom really seems to be if the connect is idle for any length of time, it disconnects. I quite regularly have to do something ''twice', including in 3 different browsers, to push through to a new connection.
Any similar from other users, possible diagnosis's or solutions?
Thanks in Advance.

I think there might be issues with some access points and different tablets. I've heard of similar things with laptops and ipads as well.
The general consensus here however is that the xoom has the fastest wifi out of any tablet device. I don't have the link but I believe one of the review sites tested this.

Thanks for the reply. Further reseach shows its apparently a known issue and is being looked at, for example:
http://www.xoomforums.com/forum/motorola-xoom-help/317-connecting-through-wifi-issues.html
And likely root cause:
https://supportforums.motorola.com/thread/46526?pubid=987654
A temporary partial work around is to change the WiFi disconnect policy to the "When screen turns off" setting. you will get a delay of about 5 seconds when first connecting to the internet after unlock, but apparently the memory leak is cleared when you reconnect this way. Continual long term browsing will eventually choke up.

No can't say as I have had any wireless issues, other than not being able to tether to my phone, but that's the phone's problem, not my Xoom, stupid Samsung.

I have had the browser FC on me after long wifi browsing. So this bug may have leaked out without getting fixed. i have tried the 3g that much but i will tonight and see what happens.

Love the eventuall lol. Yeah its not that big of a deal. Its worth it to be a first 3.0 user.

I've definitely experienced this as well. Wi-Fi disconnects and won't reconnect unless I reboot or manually turn off/on. Question, if I use the temp fix to change the Wi-Fi disconnect policy, doesn't that mean my 3G will be used and therefore my allotment of 1Gb / month will be eaten when not using the device due to background sync? Is there a way to turn off 3G as well?

Just turn 3g off... which is what I do, I will only have it on for road trips, ect.
Plus it will only use 3g if WiFi is not available.

Same issue
I had the same issue on my Xoom. Everything after long video streaming, the problem started and the video start to lag and eventually freezed.
If i try the turn off the wifi, it wil stuck at "turning off.........." forever untill i reboot it.

[Q] Wifi and me - not happening! Piece of CRAP google!

I'm sure I'm not alone in this.
My N4 won't connect to wifi. Well it connects but Won't keep a connection to complete a playstore app install nor update the system itself?
This is what I posted on "Issue 40065: Nexus 4 and Nexus 7 Wifi Drops connection Android 4.2"
New device just received. Will connect to wifi but unable to install any apps thru play store.... Just shows data transferring but none actually happens. I'm unable to install none of the gapps updates. Left it alone for 2 days did not help. removing password from router and making it an open router did not help. Now trying to decide I should return the device as it is only usable as a phone not a multimedia device which this N4 should be?
There are a lot of people having the same kind of issue on this phone. A little search brings up lots and lots of complaints.
Still unable to connect to my router encore model 2AN3.
Tried to connect to open wifi router at McD and [email protected]#$ - still no go. It will connect think about it and stops. The icon at the top turns green and gray and keeps doing it.
How ever I was able to connect to the open wifi router on another Nexus S (my older phone) and was able to download updates and install said applications from play store.
This tells me that hardware is good. Software coded so badly that it is unable to keep a connection to routers.
So if you need to use this phone on a wifi router - wait until google fix this or get another phone.
As for me - it is a shame I will have to return this phone to google as it is useless media device. Just a phone which I can get a cheap phone for 10 bucks not $400 piece of [email protected]#$%T.
Sorry for the RANT.

Also flashed rom CM10.1 stable and xylon 17 stable. Still same problem repeated. both ROMS can connect to my hotspot on my NS but unable to neither my home router nor public wifi.
A few things I have tried.
1. avoid poor wifi disabled.
2. switch chennels to 6 or 8 - tried all.
3. Resetting routers
4. Assigning static IP address
5. Cleared cache from recovery
6. changed the Wi-Fi band from 'Auto' to 2.4Ghz and 5Ghz
7. Flashed new kernel Running franko.
8. Flashed 2 other ROMS/cm10.1 and xylon17 both stable versions.
My home router have not trouble connecting to all other devices at home (NS, HP touchpad, 3 desktop and 3 other laptops, Tried with N4 being the only device that was turned on. : still no go!! WHY WHY WHY WHY WHY!!!
Also followed the directions from this thread. Still no candy.
Please take a poll and let post here if you should find a good solution.

Mine works flawlessly. You should contact Google for a RMA.

I guess its the lease period on your router that you need to change... put it to lease expiring n a day or two... shuld work.. I had this issue when I upgraded to 2.3.6 on my Atrix

I just called. This guy treated me like I'm noob. But I digress.. He asked me to turn off GPS and try again saying that GPS and wifi together can not be on at the same time. That still did not work. So there is a request for replacement. Not really sure when I will get it. But keep my finger crossed - that I get a working wifi and gps at the same time ??
Don't really want to return it though since I like the phone form factor and such!
What a shame.

You shouldn't be flashing ROMs to try and fix something as basic as this. You're only adding more variables to the problem. My WiFi has been rock solid, and so apparently is that of most other posters. This would tend to indicate that there is a specific problem with your phone.
Unless there is something seriously wrong with your router it's RMA time I reckon.

Just to re-iterate .....
Wifi works if I connect to my other nexus S's hot spot.
Wifi will not stay connected to allow me to go to play store on any wifi router (home Encore ENHWI-2AN3 firmware version 1.1.3 - Mcdee's open wifi and [email protected]#'s open wifi router.) It will connect - get a blue wifi icon with a few arrows ..... but will go to gray and back to blue and so on ....

Intermittent Wifi Disconnect - Logs included

My Nexus 6P has the bootloader unlocked but is running completely stock, un-rooted, vanilla android (MDB08M). Project Fi is my carrier. When I am at home and on *most* wireless networks, I see no issue. While I am at work, my wifi constantly disconnects and reconnects. I will pick up my phone, and it will either A) not have wifi (though I have previously been connected) and quickly reconnects or B) Will have wifi, but after some amount of use, will disconnect from wifi, then reconnect a few seconds later.
I've tried all the simple items:
Making sure "Keep wifi on during sleep" or whatever the setting is is turned on
Turn off optimization on Google Connectivity Services
Forget network and reconnect
etc...
I turned on verbose wifi logs and was able to catch a logcat of when the issue occured. The disconnect occured at almost exactly 9:29:00, as I saw my wifi go out and then almost immediately after the clock tick 9:29.
I can't find anything in particular that stands out as the cause or leads to a solution.
I assume it is some misunderstanding between my job's wireless network and my phone. My previous phone (Nexus 4) had none of these issues. I am unclear on whether this is a Marshmallow issue, Project Fi issue, or what software might be causing it. Since it only happens on this certain network, I am making the assumption it is most likely software and not a faulty wireless chip. I have no control over the wireless configuration of the network, so anything on that end is a non-starter.
Any help or direction on where to look next is greatly appreciated!

I have exactly the same issue. It seems to happen mostly at work - my phone is locked laying on my desk for some time, and when I pick it up and unlock it, there is no WiFi connection but it reconnects after few seconds. It happens randomly as sometimes WiFi connection is there after unlock. It also happend at my home wifi network, though it's more rare at home.
I have two friends at work having Nexus 6P and they don't have this issue, so it looks like something wrong with my unit. I have 'Keep wifi on during sleep' turned on. Any ideas?

If those are your bug reports, the error in the reports:
FAILURE: LOST_PROVISIONING, NeighborEvent{elapsedMs=94908702, 192.168.1.1, [(null)], RTM_NEWNEIGH, NUD_FAILED}
is the same error I'm getting. My phone disconnects while the screen is off, I've just also caught it disconnecting with the screen on too, so I'm under the impression our situations are related, if not the same.

Since Greenify's Aggressive Doze feature is what caused my status bar clock to freeze last time I had an issue, I disabled Greenify but my wifi issue persists (although not as severe). I got a logcat and saved it right after the wifi dropped and reconnected, anybody with some knowledge who can see what's going on in there?
Edit: The general consensus online is that this is a Marshmallow issue. I don't have unlimited data so at home on wifi, this is a killer.

So I reflashed my stock boot image (6.0.1_r3 MMB29M), flashed FED Patcher, flashed the latest systemless root (2.64), and deleted the legacy directory Chainfire had made for old root apps that hardcoded to su (I deleted /su/xbin_bind) to get Android Pay working again...
My wifi issues have disappeared. I've seen a lot of reports saying the issue mysteriously resolved itself, but could it have been anything I just did?
Edit: Wifi is still randomly shutting off while the screen is off, but will even sometimes turn back on. The intermittent connection dropping is gone though.

This has been a constant issue for me starting with the Developer Previews on my Nexus 5 and has now moved onto my Nexus 6P.

i'm getting sick and tired of these little issues. google needs to fix this **** asap. such bull**** to have to deal with this crap

I had this issue on my home network with my Samsung devices. My tablets and TV would always drop off. My router was a cheap Asus model and was showing its age. I bought the brand new Asus router
"Asus - Extreme Wireless-AC2400 Dual-Band Gigabit Router - Black
Model:*RT-AC87R/U"
And I have not had a single drop since. Even on marshmallow. Now I know this isn't a cheap or reasonable fix but it seems maybe older hardware is to blame. YMMV

Unfortunately this is the same router with which I am having problems as indicated in my bug report. I've also found at least a few other anecdotal accounts of problems with other Quantenna-based routers as well. The evidence seems to be fairly sparse though, so it's hard for me to draw a meaningful conclusion from what I've seen so far.
For whatever it is worth, I currently have another user with a Nexus 6P on 6.0.1 on my network on that device doesn't seem to have the same issues that I am seeing.

Well that's lame. I have had no problems since I got mine. I did get my own cable modem at the same time but don't see any connection there.

I'm guessing we're waiting on an update from Google?
My random disconnects have stopped, but wifi will still randomly shut off/turn back on in my pocket. Even in Safe Mode.
Flashing factory images and factory wiping haven't solved the problem.
Is anyone looking into this?
Edit: Even after the January security patch update, still having these issues.

It seems like my wifi issues have resolved themselves somehow.

FWIW, I was having a similar problem on my Sprint HTC One M8 after upgrading to Marshmallow. The problem happened on every wifi I would connect to... work, home, a friend's place, etc. After trying out several things, I finally fixed it by uninstalling "Sprint Connections Optimizer". I tried disabling it first, but every time I disabled it and went back into the settings, it appeared to still be enabled. So I'm not sure if disabling it was actually working.
To uninstall it, you need to go into "Manage apps" from your apps drawer to find it. I don't think it's listed with an icon in your usual set of stock and installed apps.

Posting this just in case no one has thought of it before, or someone knows something and hasn't spoken up. I have noticed a lot of people mentioning they only have this issue at work, and others who have "changed their router" and stopped the behavior.
I run a Cisco Wireless LAN Controller at home, with multiple APs (Cisco 1252 a/g/n). Typically this gives me better performance and stability than most consumer-grade stuff, but I have to wonder if there isn't a setting on this enterprise-grade stuff that is related to the disconnect issue, or if this is truly simply a Marshmallow bug. This could also be the common link with people who only have this issue at work, their work may be using Cisco enterprise Wireless gear.
I will do some more digging, I did have a spot in my house where my phone would randomly disconnect, turning on "Fast SSID Change" stopped that, so I am hoping there is something that might affect this disconnect while sleeping thing as well. I noticed my WLC reports my phone as being "Power Save Mode ON" in the client info page.
More to come if I discover something.

I have same issue at home, stock Nexus 6p and an AT&T router. Limited Data plan, so it's frustrating to be at home sitting 2' from WiFi router & drop off.
If people might say how they get their log errors & post them to Google, that'd be interesting reading.
I'm 90% sure this is a software bug. My wifi is consistent & always on, iPhones & Note 3, Roku, & PS3 have no problems connecting.
Please Google find this bug & patch it!!! (And while you're at it, re-enable Dark Theme setting!!)

Add me to the list of people having this problem. I am between several different locations on a typical week and so far, the Cisco AP's by far have the most issues. In fact at my locations with Ubiquiti AP's, I have a perfect connection with no drops.
I really hope this gets resolved soon as well. Many applications are unusable when the WiFi does its drop and reconnect dance.

[SOLVED] Connected to Wifi but no internet connectivity

I was having Wifi issues on the 6P. Connected to home wifi but no internet. The thing is, the wifi would still work randomly. It's possible that it works most of the time but as soon as I go out somewhere and out of the home wifi range, it sometimes messes up when it tries to reconnect to the network.
And yes, I realize it may not be a phone issue but maybe the router (Asus N66U with Tomato firmware).
/edit - well, I spoke too soon and I guess it's not the static IP causing the wifi issues.
It turns out it was a firewall app called AFWall+

Might want to update the title then. Although I do have that issue where when I get home i have to turn off/on wifi on my phone to get a connection.

I remembered I had set a static IP for the 6P earlier in the week so I thought I'd try to see if that was the culprit. The moment I disabled the static IP, I got internet connectivity on the 6P again. The thing is, the wifi did work earlier in the day and even the week, even with the static IP. It's possible that it works most of the time but as soon as I go out somewhere and out of the home wifi range, it sometimes messes up when it tries to reconnect to the network.

Are you still having issues or did you find a fix? I am having the exact same problem with the exact same router.

It's hard to say. This problem seems to be random. I haven't experienced it today. The only change I've made is update Cataclysm and ElementalX to the newest versions after installing the latest Android security updates. I can't guarantee I won't experience the problem again since it was happening on and off before.
No amount of disabling wifi and restarting my 6P would get internet connectivity back when the problem is happening. It just seems to start working again randomly. Is that what happens to you too?

I can't really explain it. It says I am connected to WiFi, and speedtest still works along with web browsing most of the time. But the main thing that doesn't work is my google account syncing (so emails wont appear, or delete from ym account when I do so in the app) as well as the play store not downloading or updating apps. I keep seeing issues with 5ghz, so I am gonna try connecting to my 2.4ghz as well as setting the wifi to 2.4 only, as of right now it is working. But its like you said random, and when it does happen restarting is no help. I also just set my phone to use a static ip as I heard that helped some people. I just found it weird that you have the same router and had issues.
Im on Pure Nexus with ElementalX latest update, don't have the latest security patch though.
Its only my Nexus 6p, and it seems I have no issues when I am on my girlfriends wifi. SO I am hoping the 2.4 and static IP solve it, however that sucks cause I want to use my 5ghz, as there are less devices and I get a more solid connection.

I found out it wasn't a problem with the phone or 6.0.1 at all. It was due to a firewall app called AFWall+. I figured it out when I realized internet connectivity would return when I disabled it.
Now, you might think that the app should have been one of the more obvious causes. That's true... but I had it set to Blacklist mode to only block certain apps. Internet wasn't working system wide and it only occurred on Wifi whereas LTE worked fine. So, uninstalling it seems to have fixed the problem and it hasn't happened since. Perhaps it's an issue with systemless root.
