So I just got my Note 2 this past Friday to replace my original Note. It was fantastic until yesterday.
Was playing with the cards on Google Now and the screen went black. Nothing worked until I pulled the battery and restarted. Most everything was fine after that except wifi. It keeps toggling itself on and off roughly once or twice second. It's set to stay on always so its not related to that. I can sit there and actually watch the on/off switch slide back and forth, it will do this roughly 100 times over 5 minutes and then shut off the entire phone.
Very frustrating for a new phone. any thoughts before I go exchange this?
try factory resetting it
done it, twice, still happening
Are you using the 5g wireless connection (if your router supports it)? I've had nothing but problems on recent Android versions connecting to that. It will disconnect and reconnect several times a minute. It started with my Galaxy nexus, continued with my S3, and now my Note 2.
If I connect to the standard wireless (The 2.4GHz band), everything is fine. I don't doubt it's probably my router (Netgear WNDR3400), but I hope this helps.

So I just purchased the tablet brand new about 2 weeks ago. Love it for the most part!
Over the past couple of days though, the wifi has really started to act up, and it's passing me off.. About every half hour or so, sometimes longer, sometimes shorter, the wifi will just stop working for a while. The bars will still be there, as will the little "download" and "upload" arrows lighting up as though data is still being sent and received. However, the wifi just isn't working. Pages won't load, speed test . net app won't work, nothing requiring wifi.
I usually have to go into wifi settings to disconnect and reconnect for it to start working again.
I haven't done anything different to my wifi router, and my other wifi connected devices don't seem to be having any trouble staying properly connected, so it doesn't seem like it'd be an interference issue.
Can anyone provide me with some help?
Has anyone else experienced frequent disconnects between the watch and the phone?
It was happening with my modded Note 3, which had a custom kernel so I was thinking it may be that. But now (for 2 weeks) I've been on a stock Note 4, and it keeps happening. Every once in a while, once a day or maybe once every two days, the phone and watch disconnect.
Android Wear says "connecting" but never does unless I click on Disconnect and then click on Connect, at which point it connects immediately.
I had "Find My Phone" installed, which would notify me when I got disconnected, so I thought it may be that. Uninstalled it a few days ago. Still happens. It's not a huge deal, but it's annoying and I don't see why it should happen.
Any idea?
Noticed the same with my 360 and Nexus 5. Both on stock latest versions.
Issue with mine is that the Moto360 constantly says Disconnected when trying to connect to my Note4. I click connect, it says connected and then quickly changes to Disconnected.
Been trying to figure it out for 3 days now.
I think I realized that the issue is in reconnecting.
I still don't know why sometimes it disconnects, but disconnecting itself wouldn't be an issue if then it proceeds to reconnect on its own.
But I realized that when I'm at home, I leave my phone by the computer and walk around. If I walk outside of the bluetooth range, then it disconnects. That's fine. But then it should reconnect when I come back into range, and it never does. It says "Connecting" and never reconnects unless I do it manually as I said in the OP.
So I guess the question becomes: why does it get stuck on "connecting" when it's in range and should be connected? Is this a Samsung issue or a Moto360 issue?
I have seen the same issue with my Moto 360 and an original Moto X. It normally reconnects but then once in a while it just won't. The easiest solution I have found is to turn bluetooth off and then on again on my Moto X. That always brings it back, a reboot of the 360 does not.
Well as I said in the OP, if I go into Android Wear, click Disconnect and then click Connect, it works. But there is absolutely no reason why it shouldn't auto-connect. If it disconnects, and I don't notice, the rest of the day I go without notifications until I realize the watch has disconnected. That's not how this should work.

Hi, i have the same problem, my watch always disconect to my phone (moto x), and then the bluetooth system never start again. When I enter in setup ---- bluetooth---- the bluetooth switch doesn t turn on again until phone reboot.
this is so annoying. and it seems like there's a few people experiencing the same thing but nobody seems to have hit a solution. I have yet to come up with one. if I do, i'll post on here.
Same happens with mine. It just prompts me with a "connect" screen on my phone once in a while. After connecting 2-3 times, it won't appear until next time I turn off Bluetooth.
I get this problem about 2 times per day...running with a Note 2 running 4.4.2 stock but rooted....
Last couple weeks I've had an issue will my Internet connection gets painfully slow over wifi. Today it would give me decent results on a speed test, but would take forever to start running test. Chrome, Facebook, etc, would be really slow to load anything. Similar thing happened last week, except that time speed test came back really slow.
Both times a restart fixed the problem.
Any idea what could be causing this? Before these two times, I never had any issues and never rebooted the phone except if the battery died. I was up to 15 days without any issues and no restarts. Now I've restarted twice in the last 8 days to fix a problem.
I'm following the post closely.
I have similar issues and at first I thought it could be my wifi modem. Restarted that and it seemed to work for a couple days then the same issue. Major slow down. I tested other devices that I have connected to my wifi, none of which have duplicated the major slow down of the wifi. I have done the update and I'll post in a week or so if this has fixed the issue.
I know it wasnt a router issue because my friend has a note 4 and didn't have any issues while I did.
I did a factory reset this morning, will see if it happens again.
I'm also curious about this. Is your wifi AC enabled?
Same here, slow slow slow. My nexus 7 works fine so it isn't wifi.

Did that help?
I'm going to take mine to the At&t store this morning. Facebook just sits there and does nothing, Instagram is the same can't receive email either and that's after doing a factory reset.
I took it in and they are now sending me to the device support center. The rep couldn't get it to hook up with there wifi.
Thanks for the update. Mine isn't quite that bad. It'll just slow down to about 5mb/s while the other devices on the network are fine

Have you tried to turn off WiFi power savings off. You do that from the dialer, *#0011#, go to wifi settings and turn it off. It's known to samsung phones to cause issues with power savings on.

Turned it off. Will see if that does anything.
Hasn't happened in the last week.

Do a speed test it'll surprise you.

Not seeing much of a difference in a speed test. I'm at the outer edge of my wife network, and I'm seeing 10 down /5 up. If I go right underneath my access point, I'll get 50/20.
I take it back, I got 10/5 under the router, while a wired connection got 40/10.
Gonna restart the access point and see what I get.
An iPhone 6 just did 15/1.5
Another test for me and I got 8/6
Restarted the phone and got 20/4.
What is causing this?
Same issue for me as well. It's only the wifi on my phone and it just started last week. I even did a hard reset to fix it and no luck. It's laggy as hell now and I just leave it on LTE so I don't have to wait so long. Any updates?
My issue is worse than it ever was. Instead of happening every 6-7 days without a restart, it happens after 1 day now. It's not so much that WiFi is slow, it's that it takes forever to start downloading and for Web pages to load up. 30-40 seconds before a page will begin to load.
I have a replacement phone coming from att today.
I'm about to throw this stupid thing against the wall. Since I bought this thing a couple months ago I've noticed that sometimes when I am watching youtube a box will pop up telling me that I've connected to T1 (the name of my wifi network). It seemed odd because I was already connected but whatever. Then lately I've been using the HBOgo app to watch shows, and at some point during every episode the app will freeze and I will have to back out and then resume the episode. I assumed it was the HBO app, but I've started to realize that it is the tablet itself freezing and disabling wifi. I realized this today when I was trying to download some files. Nothing too large, 60-100mb, but the downloads were always failing before they could complete so I would have to start over. I start to download a file, the download should only take a couple minutes at the most, but before it completes, somewhere between 30% to 95% downloaded, the whole tablet freezes up and becomes completely unresponsive. Then the wifi icon disappears from the top right, and the wifi button next to location, bluetooth, etc, goes from green to gray, then after a few seconds it goes back to green and a box pops up telling me that I am connected to my wifi network again. I start the download again and the exact same thing happens. I've also noticed that the tablet gets quite hot around the camera.
It does the same thing when connected to my TP Link Archer C7 (just using N, not AC) and a netgear router I had lying around. I doubt it's the network as the router has no way to forcibly disable wifi on my tablet. When I said that the wifi button goes from green to gray, it's as if I had tapped it to manually disable wifi, even though I did no such thing.
Also, it does seem like if I turn the screen off and let it sit for a while to cool down, it will work until it heats up again. Once it starts to feel hot though the wifi will start disabling itself and downloads start failing again.
I'm only about 10 feet away from the router with direct line of site.
So is it just overheating? Defective and time to send it in under warranty?
Everything is stock.

looks like the most recent OTA update breaks wifi, read that thread.... i got lucky as i usually just blindly accept OTA's when prompted... but i checked here and found that it was causing problems
I have a Samsung Tablet (android 7.0) four CCAs, all on good 5ghz wifi. Ever since the tablet was upgraded to 7.0, it's had an issue where, about half the time, once I select a device to cast to from Spotify/Pandora (either one), it disconnects the WiFi on the tablet. It will physically turn the wifi off, and it will come back on after about 20 seconds. After then it will work for a bit.
I have a LG G5 that has never had this issue. It also is running 7.0.
Could someone shed some light on what is happening when I attempt to cast? Why could it disconnect my tablet WiFi? The wifi comes from a RT-N66U, of which I've tried both old and new firmwares, but it made no difference. I've also done two factory resets on the tablet and turned off battery optimization on Spotify, pandora, and the Home app. Not sure what else to do. Finally, I've also done factory resets on all CCAs. Any input is appreciated. Thanks.
