I got my 7.7 yesterday. All is working great, but about every 30 minuttes of use, the WLAN-connection hangs. The WLAN-icon stays lit, but the tab is not able to send/receive data. To get it to work again, I have to disable WLAN and then enable again. It then works for about 30 more minuttes.
I have not installed any task-killers or battery-enhancers etc..
The router is a D-Link DIR 555. I use several PCs and Phones on the same router without losing connections ever. Encryption-type is WPA2.
Any ideas?
Bro here is the same problem really confusing me evrytime the wlan disconnects.
Have you checked that your WLAN settings do not put the tablet wifi to sleep ?
Settings -> Wireless and Networks -> Wi-Fi settings -> Wi-Fi sleep policy
I'm having the same problem here, and my wifi policy is set to never, so when that happens I have to turn off/on wifi.. not good!.
I have the LTE version, but am running it without a data plan. I have the same issue with WIFI. The connection will hang after 30min to an hour of use. It is VERY annoying. I ran Speedtest, and i get an interesting result, over wifi i get a very fast download speed (15+Mb/s) but my upload totally hangs. It just sits there. On the same wifi, with my Galaxy Nexus, i have no problem with download or upload.
I've seen several threads across the internet about the problem, and no one seems to really know why. Some people say you need to change settings in your router, and it isnt the Galaxy 7.7's fault, but, i don't know if I buy that. I have the same problem at the Airport, and, i cannot exactly go and change the router config there. I am hoping that there will be an update to the firmware for the wireless radio, either separate or with ICS.
WIFI Problems Solved!!!
Hi,
I had the annoying wifi problem. It would work really fast for a few minutes and decide to stop working all of a sudden.
I fixed the problem by setting the maximum Router output to 54mbps G. Seems like the galaxy tab 7.7 does not like the N settings.
Now it works flawlessly and I will just use it at G speeds until Samsung provides an update. (I really do not notice the difference in speeds between G and N. Just the peace of mind that it will work every time.)
I hope that solves some of the other users' problems.

Same problem here on gtab 10.1, 7plus and note :S something wrong with samsung drivers

Hi,
I have realized that my wifi connection drops down from more than 20 to only 1 Mbps with my lg g2. It happens with 2 routers and seems that if I reconnect the phone then I go back to more than 20 (and short later in goes down again). Any idea what can be?
No suggestions on this one? I tried the location services changes with no success. I would say it is some app causing issues, but no idea which one could be...

got exactly the same problem
switching wifi off an on solves the problem for 2 minutes or so. then it drops to 1mbps again. tried different routers.
I figured out that it only concerns internet traffic. LAN traffic remains at full speed.
WHO can help please? :cyclops:
hmmm. wonder if this is the same problem a lot nexus 5 owners have including me.. there's quite a big thread on it in n5 QA section
there's no fix but workaround solutions include running in 2g mode or turning off data when on WiFi and even making a script to do so automatically when entering WiFi areas.
http://forum.xda-developers.com/google-nexus-5/help/slow-wifi-n5-t2514501
thank you for that interesting link.
unfortunately the solution turning mobile data off didn't worked for me.
I also tried static IP instead of DHCP - no success.
one strange thing, as already mentioned: LAN traffic to my computer works perfectly with max speed. (copying files e.g.)
so, wifi works in principle. It's about internet traffic only.
but which kind of software/hardware is able to distinguish between internet- and local traffic?
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?

I haven't made much headway but I have filed an Android bug here: https://code.google.com/p/android/issues/detail?id=196035
It has the attention of the networking devs. Any further evidence (bug report!) you can provide there would be extremely helpful.

I'm seeing this same issue as well, I submitted logs to the bug report opened by cpswaim, but I wonder if this is a different issue and I should have opened a new bug.

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.
Thank you for the bug reports!

I wasn't getting that error either, one of the Google engineers on cpswaim's bug asked me to open a new bug report instead and I did so here: https://code.google.com/p/android/issues/detail?id=197272

Thanks for the link!
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.
Is anyone else having problems staying connected to WiFi and/or cell service with the international version of this phone? After a while, everything seems to die. Putting it in airplane mode and taking it back out seems to fix it.
See the attached screenshots. The wifi will show connected with issues, and the cell service will be zero signal. After toggling airplane mode, everything goes back to normal.
Yours is IN2025 right? Are you on 10.5.4? I had some wifi issues but not sure if it was the phone or ISP problem. I updated to 10.5.5, haven't had a connectivity problem since. The update log specifically points to addressing connectivity problems

Yep, IN2025, but in 10.5.5. What is funny is that it has not happened once all day. It happened so many times the past few days before, that I was able to tell it was usually after putting it down for a period of time (maybe going I to a deeper sleep?). At this point, I'm hoping it will not come back, but I also know nothing changed to have fixed it either.
I wonder if it is related to the wifi calling bug, where not everyone sees it. I noticed the people who aren't getting wifi calling seem to be connected to APs that allow TKIP. I have Deco M9 Plus "mesh" APs, which are generally great, but don't offer much in the way of advanced configuration options... like not being able to select AES over TKIP.
I guess I'm still having issues. Almost immediately after I posted that reply, I noticed my cellular signal was showing really low. It didn't seem to resolve on its own, so I shut wifi off (wifi seemed fine this time). As soon as I shut wifi off, I got LTE+ mobile data, and the signal strength jumped up. I have only recently actually started to trust the signal strength indicator, after the fiasco with Apple marking them up a bit to make it seem like the signal was stronger.
It should be noted this is a partner tower outside my house (which is usually a strong signal) and not the home cell spot. Not sure why I'm not connected to the latter, as I haven't left the house today (which is usually when I pick that up).
Are you by any chance with Charter/Spectrum ISP? My aging netgear router crashed a few times as I was flashing and rooting but I just kept going so couldn't really tell what was going on. I am with Google Fi and have wifi calling enabled but have not had any issues. I do not have the mobile/wifi linking. I did see on 1+ forum that someone had an issue with his router crashing but I believe he had mobile and wifi connection linking enabled.
