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)
We recently signed up for TWC cable at home and have purchased our own Netgear C6300 modem/router. Since then, I have had a very noticeable delay in certain apps. For Google Play store, there is always an exact 15 second delay from the time I press install to when the app actually starts downloading. For YouTube, the thumbnails take about 10-15 seconds to load. For Netflix, the app takes about 10-15 seconds just to connect to my account and display thumbnails. These are the only apps affected, which seems strange. This only happens when connected to the wifi network at home from my Note 3. We have the 200Mbs internet plan and I can confirm we are getting 235Mbs when hardwired to the router and I'm getting 230Mbs on my Note 3 through wifi at the same time I am seeing this delay. So I don't see the internet speed being the problem. If I disconnect from the wifi and run on Verizon 4G LTE, there is no delay at all. When using a different wifi network with my Note 3 in different locations (work, friends house, etc) there is no delay. When using my ASUS tablet and my home wifi network, there is no delay within any of these apps. This only happens with the new Netgear C6300 modem/router and my Note 3. The other strange thing is that once this delay has passed, I have no issue with download speeds or any buffering during playback. It all just seems to be that initial connection. I even went as far as doing a hard reset on my Note 3 no see if that solved the issue, but nope. I am currently running Android 5.0 and the Netgear 6300 is running firmware V2.01.19. Has anyone else experienced this? Have any ideas as far as solutions? Help is much appreciated.
Hi. I'm currently experiencing a weird issue with my phone and wondered if I was alone.
So basically, over some wifi, some stuff behaves in a weird way. For example, Ebay, Twitter and LPMobile (local french news app) can't download images. Also, Clash Royale can't update and i have issues connecting games to Google Play Games. This bug only occurs on my home network tho. Everything works just fine on Mobile Data and some other wifi connections (School, Work...) I believe the problem is somewhat linked to software since i had this issue on my older phone (Honor 7x). I believe it is linked to the Packet flooding Issue back in January of this year. However, I tried installing many different versions of Google Play Services on my device and nothing changed.
Does anyone experience this issue?
My home Router is a Linksys EA7500 Max-Stream, if this can help.
Thank you!
It appears I am having similar issue when I am on wifi. Facebook, Instagram will not load pictures and new posts.
Have you resolved your issue?

No, I haven't resolved it, tho from what I tried, it seems to be linked to my router. What's your router?

From what you have described this seems to be an issue with your WiFi connection at home and not the phone. I would reset the router and see if that resolved your issue.
I have a similar issue. I own both a 6 and 6t - the 6 no issues gets on wifi just fine but the 6t? Not so much. I will connect up all day long to 2.4Ghz wireless and get on the internet but if I put it on 5Ghz (which all my stuff uses) it connects, get an ip but will go no where on the internet. It's like it has no DNS or something. Frustrating as hell. I opened a support ticket with OnePlus and they told me to send it back. (PS I tired all the fixes, router reboot, forget network, I even tried a factory data reset...nothing same behavior).
Wifi dropping issue
Same issue with my 6t. Frist oneplus devide and disappointed. It's been weeks i havent used my device.. because wifi doesont works..
It's anyone using Private DNS with cloudflare? That gave me issues with my wifi at work until I disabled it. It didn't give me problems anywhere else though.
my wifi works great; most likely, those that are having wifi problems have issues with their router/modem/isp;
usually, its not the phone where the wifi problem is..

Hello,
I just purchased this Samsung Galaxy Tab A 10.1 (2019) SM-T510 tablet a few days ago and I've had strange issues with 5GHz Wi-Fi from the start.
The problem is that when I'm connected to my 5GHz wireless network and open particular apps (that were not already running or in the background), the apps have no connectivity at all and after waiting several minutes might still not have connectivity or run at a very low network speed (0-3Mbps). The apps I have experienced these issues with so far are Discord, MX Player/VLC Player (when trying to run files from local network), Firefox browser and Play Store (when downloading or updating apps).
Chrome, YouTube and Speedtest run fine whenever I'm connected to the network and start them, but Speedtest sometimes gives a download speed of 2-6 Mbps and other times 80+Mbps or more. Upload speed is always 170Mbps or more. Server does not matter. Chrome rarely shows a "website not available" screen for like 0,5 seconds before succesfully connecting to a website.
However, if I launch for example Discord in Pop-up view and then run Speedtest in the background, suddenly Discord gets full connectivity as soon as I start the speed test even though normally it would take minutes or not get connectivity at all.
The Wi-Fi settings in android show that the connection speed to the router is around 433 Mbps despite the connection working very slowly even within local network.
The issues persist even when I'm next to the router and have disconnected every other device from the Wi-Fi.
My Galaxy S7 and Nexus 7 are also connected to the same 5GHz network and do not have any connection issues with any apps and S7 always gets around 250Mbps down and Nexus 7 150Mbps down on speedtest.
However, If I'm connected to the same network on 2.4GHz, everything just...completely works. Discord, Video Players and browsers have full connectivity and speed as soon as I start them. No issues at all. Speedtest gets 40-50Mbps Download and Upload speed all the time without speed drops at all. This at least makes the device less annoying to use, but I would still much prefer to use the faster 5GHz network.
So far I've tried the following things to no effect:
-Restarting tablet and router
-Forget and readd the network in settings
-Reset all network and connectivity settings in android
-Played with Wifi Fixer app from Play Store
-802.11ac, 802.11a and 802.11n only modes in router instead of 802.11a/n/ac mixed
-Different Wi-Fi channels and channel widths in router
-Assigned a static IP
Planning on doing a factory reset on both the tablet and router later, but any help or ideas would be appreciated. Don't want to return this thing just yet.
Couple of years later, but I have the exact same issue. Did you ever find a solution?
Hi everyone,
I've got a Samsung M30s a month ago, and I never had issues until now.
Google Play Store and Youtube started working very very slowly maybe a week ago, and now they literally do not load anything whenever I am connected to the Wifi.
Both the apps work fine on mobile data, and Youtube works fine when I open it on the Google Chrome app.
I've tried every troubleshooting I found:
-Clearing cache and data from both apps and Google Play Services;
-Resetting the phone;
-Changing the WiFi DNS to Google's parameters (8.8.8.8 and 8.8.4.4);
-Logging in and out of my Google account numerous time, and relogging directly from the Play Store,
-Turning off all data savers option;
-Turning off all battery saving options;
-Disabling IPv4 or IPv6 on the WiFi.
About my wifi: I am using a router that does not belong to me, but it is an hotspot of my home provider (Vodafone) that i can use for free since I am their client on another WiFi at my parents house.
I tried connecting both to the wifi with my log in details directly or using my computer hotspot as a middle point.
I cannot currently go to my parents house to see if the issue persist using a personal wifi connection (as we are on a strict lockdown here in Italy).
The phone is not rooted nor it has the bootloader unblocked, I like modding and have experience with a lot of Samsung devices but I like the Samsung One interface and I don't want to void the warranty so soon.
My current software version is PPR1180610011M307FNXXU2ASL2.
The phone model is SM-M307FN (European version with the Exynos chip).
I am writing here because everything I tried literally hasn't worked and I really don't know what else to do.
Has anybody else experienced this issue?
Try on wifi from another Internet provider
I do not think it is a matter of phone itself
But: how does Youtube work on a laptop connected to same wifi ?

That's my question too. For what's worth i tried connecting to a phone hotspot (so internet passing through mobile data) and things still don't work.
Youtube works fine on all laptops i know connected to the wifi.
Also worth nothing: when I change DNS to 8.8.4.4. And 8.8.8.8, the situation goes back to normal for a few minutes and then it slows down again.

Yes to a certain degree. I tried a couple of a vpn with different location (namely USA and other parts of Europe), and the apps did work faster but the issue appeared after a scrolling down the page for a couple of times. I contacted Samsung Support and they told me it is a known issue for a good number of people and that Google is working on it (here's the link to the support Google forum:https://support.google.com/googleplay/thread/40380785?hl=en ).
I guess there'ss nothing to do but to wait.

Have never come across such a weird and specific issue, hope they fix it soon
i have a similar issue with google play store.....also i noticed one thing is that even though i have turned on auto updates & am connected to the wifi the entire time(literally) the apps never update on their own....at one point when i checked the apps i had over 30+ apps to update(some of them were system apps)......& yes youtube is lagging for me as well...
