This may be better suited for the development forum. I am stock rooted 6.2.2.
Since the update, on my university wpa2 enterprise peap network I have had consistent disconnects every few minutes. My network admin suggested changing something in wpa_supplicant.conf, however I have no idea where that is located on the kindle. Has anyone else seen this problem? I did not notice it before 6.2.2, but it may have been there. It reconnnects almost instantly but kills any streaming apps.
Use wpa2 personal here, rooted 6.2.2, no issues.

Personal works fine for me as well. It is enterprise with multiple access points, I think it is hopping for no good reason now.
They may have changed the roam sensitivity, or enabled opportunistic key caching or something.
The bigger problem seems to be that the KF doesn't roam smoothly from one AP to another. I haven't had a chance to examine why, but my first guess would be that it does a complete dhcp release / renew on every roam.
I notice it a lot because I have my APs spaced for 5Ghz, so the 2.4s run at like 10mw and I roam every 20-30 feet. If it roamed nicely, it wouldn't really matter how often it roams.
Seems to be more frequent with high bandwidth apps, such as splashtop remote desktop. Vince for example only has trouble every once in a while, splashtop reconnected every 2 minutes or so. I don't believe the app is at fault here. My whole wiring goes out and reconnects. Sometimes it is just while browsing the web, stationary in a classroom.
I had the same problem and was running CM7. I realized that it always disconnected with I was using the Facebook app. I have since uninstalled that app and access FB via my browser. I haven't had a single disconnect in the last couple of weeks and I was having multiple disconnects per day.
I'm having problems connecting to the corperate wifi with my Nexus 10, I've used an android tablet berfore on it, TF101 connected without any problems, I've seen issues reported with the Nexus 7 and Wifi, has anyone else had and issues connecting to WPA/EAP with Certifcate authentication.
The device is crrectly registered as it can connect to another SSID which uses the same mac database
Working fine for me, however I have been disconnected twice in the last 2 days,

Bump.
Any fix to this issue? We use WPA/EAS and I get "not in range". Some people got it to work and some didnt. there's an open bug being tracked on Google (Issue 34212) but no workable solution on the N10.
Having problems with optimium wifi. I have to sign in everytime, while on my phone/laptop its not needed.
I downloaded the wifi register app from optimium, but it can't sign in with that. Any solution?

My connection stays strong (max bars) when for example playing a youtube video, but after while the video endlessly buffers (or freezes) until, either I jump in and out of multitasking screen or restart the WiFi connection. It's as if it can't reinitialize the stream for some reason. I have the same problem downloading apps and other media, i.e. good signal, stable connection, but just seems to time out continuously. It's driving me mental, without reliable WiFi the device is next to useless. I'm hoping it's a software issue that will be addressed soon, but if not I suppose it's RMA time.

I had the same issue with YouTube last night. It took me a while to get the connection back at one point. I rebooted the device and the router and I eventually got my connection back. I would tend to think it is a combination of Android and the router that will eventually be worked out with an Android software update.
The goofy title says it all. I want to leave my Nexus 7 in my truck all the time, turned on, and have it automatically hook up to my GS4 through Bluetooth whenever its close enough to connect. So far I have the mount and have balanced out the charger so it barely charges more than it uses. I have increased my battery by only about 5% in three days. I realize I may need more power if I do much more than leave the screen on all the time and I can adjust for that.
I would like to be able to run Waze and Escort Live on my Gen1 N7 that doesn't have its own internet connection. I leave the Bluetooth enabled on my GS4 all the time and when I get in my truck it automatically connects to the Ford Sync so that part is good. What I would also like is for the N7 to connect to GS4 and get an internet connection without any intervention by me. I would rather not use WiFi tethering as it doubt my phone could handle that all day long.
Is this possible?
Really? Nobody does this?
I tried Easy tether from the Play Store today with my N10 but haven't tried it yet with my N7. It seems rather slow, and I am not sure yet if it connects automatically.
I have a Note 3 and an S4. I also have Panasonic and Nikon cameras with built-in WiFi. The issue is that the WiFi features of the cameras work by setting up a WiFi network in the camera and then connecting to it via WiFi on the phone. But, the Sammy's have a feature that looks for a live internet connection and drops back to mobile data if it doesn't find it. Since the camera doesn't provide internet (duh) the phones immediately disconnect and drop back to mobile data.
I know how to shut down that feature on the S4, but that takes a lot of steps and is a PITA to do several times during the day while out and about. On the Note 3, I haven't found a way to shut it off at all.
Ideally, we would be able to shut that feature off on specific connections ONLY - does anyone know of an app or something that would allow that? Or - a shortcut (widget?) that would give a toggle to that feature?
Have you tried turning off "Auto Network Switch" in the advanced settings under Wi-Fi? II have a galaxy camera which does something similar but I haven't tried connecting to it yet.

I have had my new Galaxy Note 3 for about 3 weeks now, and have had an issue with certain apps not connecting to the internet over wifi. All of the google apps (youtube, play store, hangouts, gmail, etc) are not able to connect to the internet over any wifi hotspot, or if they do, they're painfully slow.
I have changed MTU settings on my home router, DNS settings, wifi auto switch is off on the phone.
Here's the kicker. If I enable airplane mode first, then turn wifi on, everything works great. I suspect this to somehow be related to the SIM card? Really should have nothing to do with wifi, but who knows...
I should add that I've owned a couple other android phones that have had this issue, but it seemed to have just "worked itself out" after a day or so. (Droid 4, Stratosphere II)
Have you tried a 30/30/30 hard reset on the router yet?
Does a laptop connected via Wi-Fi also have similar issues?

I have hard reset and factory reset the router a few times, even went so far as to buy a brand new router and use it. No difference.
I get 26/8 speeds on two different laptops, and one desktop, all with ping times down to about 18ms (as shown on speedtest.net)
spoke with a helpful rep at verizon today, who supposedly called samsung regarding this fix while I was on hold. My replacement should be here tomorrow. This issue is exactly the same as when older android phones would not connect to google (signal indicators would be white instead of blue). It seems like something to do with ssl traffic.
Anyhow, will post back after i've played with the replacement for a bit.

The next most common thing that it would be is the channel that your router is set to. You want to use a frequency that has little interference and there is an app called WiFi Analyzer to help figure it out for your surroundings.
The reason that the laptops might work ok is because the channel can be set within Windows and are most likely set to a different random number between 1-11 than your phone is.
I have found open channels and used those, which made no difference. I believe this may be a google issue as evidenced here (granted these guys are talking about the nexus 5, the issue is very much the same)
https://productforums.google.com/forum/#!topic/nexus/SN03aclu7B8[1-25-false]
I received my replacement today, no dice. I also bought a new router today, no dice. I've tried every channel 1-12, no dice.
The only thing that works is to enable airplane mode, then turn wifi on. I then see full speeds on play store, youtube, gmail, and hangouts. Interestingly enough, the facebook app is affected by this, as well as all push notifications.
It should be noted that the replacement note 3 exhibits the exact same behavior. This leads me to believe there is a modem issue causing the phone to switch back and forth between LTE and wifi, or something along those lines (if the cell radio is off, wifi works great)

That is truly odd. I suppose it could be believable that an ISP throttled traffic to specific blocks (net neutrality anyone?), but I don't know why that would cause an interface change on the handset.
There are some apps which are network interface aware - e.g. as an example carriers will use split DNS and inbound IP firewalling so only people on their own network can resolve the IPs of MMS (APN) servers or *send* data to them. That prevents them from being DDOS'ed and I suppose other attacks from anything but their own network - which they have well instrumented. But that means that the MMS apps can not use whatever IP interface happens to be up - either for DNS service or for IP routing - so they need to be able to bring up a specific IP interface, use DNS that is bound through that interface, and route through that interface as well.
I was going through the apps on my phone the other night with a package browser (Package Explorer (Ribo), btw) and I was stunned at how many apps have "CHANGE_NETWORK_STATE" privileges.
What I'm wondering is if you have an app installed that has gone nuts and is toggling on/off your cell I/F. Something like that would be consistent with your observations.
Is there anything relevant happening in your device logcat when this is going on?

There are no apps installed other than the stock verizon/samsung apps. I have reset to factory in preparation for sending this unit back to vz, however it appears i'll be keeping it since the replacement didn't work any better.
Nothing interesting from logcat. Just a lot of IRListener messages, and DalvikVM occasionally clearing ram.
I can see why you would be pulling your hair out.
And the fact that you observe the same behavior with two different units (completely different hardware) and two different routers means one of two things:
- the problem is the handset/software
- the problem is not the handset/software.
Not trying to be funny there. What I mean by the above is that for you to pull two devices out of Samsung's production line at random (unless you happened to get two devices from a single batch of defective units), then the problem couldn't possibly be a low-probability defect thing: either it happens on a very large fraction of all N3 handsets, or the problem actually has nothing to do with the handset at all.
e.g. suppose Sammy shipped handsets where 1 out of 100 had the problem you observe. For you to end up with two of them in a row, the odds of that happening would be 1 in 10,000. If affected half of all handsets, then your odds would be more reasonable - 1 out of 4.
But it sure seems like if it affected half of all owners... or even 10% of all owners, people would be piling in in droves to complain.
I haven't noticed it on my N3, but I have other devices so I'm not sure how much I have used it for e.g. Youtube streaming. I do leave both WiFi and the cell on, and haven't noticed what is happening to you, but I am on MJ7 instead of MJE, and my WiFi is older (802.11g), so maybe if it is a bug it that wouldn't even show up with my setup even if it were the N3's fault.
(BTW, that offers a suggestion - because the N3 is so new it has 802.11ac capabilities - and I suppose your new router does too - if you turn off some capabilities, does the problem disappear? For instance turn off 802.11ac or 802.11n or 5Ghz band usage on the router, does that change anything?)
The other alternatives? Some kind of burst RF noise in your local environment? You earlier said
are not able to connect to the internet over any wifi hotspot, or if they do, they're painfully slow.

were the "any wifi hotspot" APs that were all relatively close to a single location, or were they widely dispersed (miles apart)? If they were miles apart, then the problem isn't ISM-band interference. Even if it were, interference from non 802.11 devices (bluetooth devices, baby monitors, microwaves, some wireless cameras, etc) isn't going to show up using a scanning app. Relatively sophisticated equipment would be needed to make that determination. Or a search and destroy mission.
I will say that I had a similar problem a few weeks back (using completely different gear) - I was tethering to a different Android phone (USB tether), and Web browsing on the client device (N7 tab) was fine except the Google Play store app - data would only come dribbling out of it. I couldn't even complete a single app listing, much less begin an app download. At the time I just chalked it up to a temporary problem with Google's Play store. But now it makes me wonder if it isn't something more subtle - as you noted, Google servers seem to be a commonality you are observing. Maybe some ridiculous bug involving Google's single credential efforts?
Well, now I'm rambling and I really haven't given you a suggestion. Maybe something I said will jog you in a different direction and you'll figure it out. If it really is something generic to the current Note 3, it seems like Google would want to know about it. I wonder if it is even possible to get telephone support from Google - they don't really have a reputation as being a consumer-oriented business.
good luck

Thank you for all of your help. I am sort of an amateur RF "enthusiast" myself. This happens in more than one location, literally every wifi location i've connected to.
I do believe on past handsets a new sim card sorted this out for some reason, however the vz rep that I spoke with activated a new one that I had gotten with the note 3, but not activated at the time, since my droid 4's sim card was "current enough".
I am lead to believe that this is a modem firmware issue, due to the fact that when the cell radio is off (doesn't matter if mobile data is on or off) the wifi works great. I am running MJE, and would be willing to try and downgrade to the previous radio to see if it makes a difference, but I don't know if that's even possible without causing some damage.
edit: I just realized that the replacement phone is running MJ7...so not sure it would matter.
Resolved
Ok guys, I figured this out, sort of.
I went into an angry router swapping/resetting frenzy when I figured out that the replacement acted the same.
My original setup consisted of: (I have a lot of wired devices in my house)
Comcast Gateway (set up as a normal cable modem, wifi/firewall/dhcp disabled) ----> Linksys WRT54G w/ DD-WRT (wifi off, using for firewall/routing) -----> Zonet N router (no dhcp, using as a switch, wifi off) --------> Linksys BEFW11S4 (used as a switch) ------> Netgear WNR1000V2 (used as a switch and second wifi access point occasionally)
During this frenzy, I eliminated the Zonet unit, and the BEFW11s4. My network now looks like this:
Comcast Gateway ----> Netgear WNR1000V2 (router/firewall/dhcp/wifi access point) -----> WRT54G (as a switch)
This seems to have solved my problem. I noticed while troubleshooting that if I disconnected the segment between the Zonet and the BEFW11S4, my phone would work perfectly fine. I believe that taking the BEFW11S4 out of the picture solved my problem, even though my data was not riding on that segment of the network.
Still, I am perplexed as to why the airplane mode trick fixed the issue.
LOL. I have a pile of Cisco routers if you want to buy them - and I'll throw in some token ring gear and another BEFW11S4 for free.
But seriously - you did the right thing by (experimentally) simplifying; the more complex an environment is, the more opportunities there are for bug expression.
Glad everything worked out - and I await your PM inquiring about my Cisco pile
I never wanted to upgrade from my WRT54G V1! What an awesome, rock solid router! However, need faster wireless speeds nowadays.
I was trying to keep that as my firewall, since the dd-wrt firewall is so much more robust than that of the netgear, also the netgear does not support nat loopback (something I really would like to have)
