I've notice a slight issue with my Tab. Sometimes, when it's been left sleeping for a while it 'forgets' to go back to wifi and stays on 3G connectivity, even though I'm sitting right next to the wlan router. If I check the wifi settings, the network is listed as 'out of range'. If I turn off wifi and then back on again, it connects without any trouble.
Has anyone else noticed this behaviour?
This is most certainly a router issue. The simplest fix is to reserve ip up for the tab and use fixed up settings.
I do this with all my LAN devices anyway because it adds a little security, as well as better interconnectivity.
But really you should investigate the router.
Somehow I doubt that. I'm using DD-WRT running on the classic LinkSys WRT54G, a combo that is widely famed for it reliability. I also have the router set up to serve a fixed IP to the Galaxy Tab, determined by the MAC address of the Tabs wireless interface.
I'm also running quite a few other wifi devices with the router, including three other android devices (G1, milestone, nook), and none of them show the same behavior.
I see... how many of your other devices use a dual band revision n radio? In my experience this can be a headache, even for custom firmware.
None, as far as I know. I'm not entirely sure about my wifes Motorola Milestone, but I'm pretty sure the G1 and the nook use bog standard 802.11g. I think you're right that this might be the problem. Any ideas how to improve that? It's not really a problem, just a slight blemish on the otherwise awesome experience.
This is well known android behavior making wi-fi sleep to preserver battery.
There are some mods to keep it on when sleeping.

Yes, and there's nothing wrong with that. I certainly don't want wifi on all the time, I just want it to reconnect when it wakes up.
Ill look into your router tomorrow, but atm I'd say there wont be much you can do other than force g only on the router. This will stop the tab from sending crc/ plcp overhead on both bands. Crazy as it sounds, the tabs radio is actually interfering with itself in this scenario.
I just replaced my HTC HD2 with the Samsung Galaxy Tab and have the exact same problem. The HD easily picked up my work and home WiFi when I moved between them, but the Tab 'forgets' to reconnect after standby.
I'm having this problem too. Every morning I need to turn off the wifi, then immediately turn it back on, before it will reconnect. This is with an Asus WL520GC running DD-WRT.
Yes, seems to be a router/device compatibility issue.
My tab works fine in my uni network (and it has quite a few dark spots), all of my friend's networks but it intermittingly fails to reconnect to my home wlan. I have a sky router (sagem actually).

I have seen this on various routers before and encountered it again last night.
There is a discussion on the cause here:
http://forum.xda-developers.com/showthread.php?t=839367&highlight=connect+wifi&page=3
It is due to the lease expiring from the access point and the device requesting the old IP with first sending a discovery message.
One work around - not the best - is to reboot the router. Then the Tab seems able to connect. Also I think if you connect ofter to the router you might not see this as the device will ask for a new lease.
Another - from the above referenced post - is to create a DHCP reservation for the Tab. This will ensure it gets the same IP address every time. I made this change to my router - so we will see.
Hope this helps.
Samsung Galaxy tab won't connect to WEP wireless
I am trying to get my Galaxy tab to connect to my HTC HD2 that is set up as a wi-fi hotspot.
My galaxy tab will connect to all WPA/WP2 networks but not the WEP. Please help.
mine does the same on a SMC Gateway (SMC8014WN) aswell as a D-Link Router (DIR-665)
I am going nuts here because of the same problem. Tab worked flawlessly for the last 4 months, found any router and had no wifi problems until recently. I have a D-Link DGL-4500 gaming router, and my dsl modem router also has a wifi connection. I suspect from the new firmware. Mine is a Euro model. I dont know why I upgraded from JK5 to JMG stock firmware, and wifi issues started. D-link's logs reports that it receives a deauth from the device and the connection ends... and never revives. Sometimes it happens 3-4 times in an hour, sometimes it stays connected for hours. I tried everything, static IP, delete dhcp list, etc. I have reset the device twice to factory defaults. Even then it disconnected the first minute I turned it on and set the wifi. So it should be a firmware issue. I realize that the wifi signal is also weaker now compared to the previous firmware. Congrats SAMSUNG! The Tab is consuming my data plan even when I am home. And I wonder how wifi only Tab is going to handle this problem. DOES ANYONE KNOW IF WE CAN DOWNGRADE FROM JMG?? Help is appreciated.
my tab does the same thing (so does my x10). But when I open my browser, or anything that needs wifi, it reconnects automatically, however the browser usually needs to be refreshed (retry).

exactly the same behaviour. Every morning, I'm connected to my router but nothing works. Turn-OFF->ON and it works again
I should have noticed Roto's entering line. See: http://forum.xda-developers.com/showthread.php?t=939360.
Since JMG has wifi isuues, I jumped onto JMI !
I have issues on Wi-Fi with my one where with my Samsung glide no problems . I have a Belkin router wireless N and it normally works fine but with the one I get occasional drops and reconnects. Anyone else have this issue. I am on stock rogers. My Wi-Fi has security enabled as well.

Did you turn on Power Saver and Sleep Mode? Click the Power Saver mode in the Power menu in Settings. You can select what Power Saver controls. Untick Data Connection, and if you want, turn off Sleep Mode as well.
I have noticed some issued. I have the developer edition and upgraded from a nexus 4. There seems to be issues with the One releasing wifi and reconnecting to data or vice versa.
In some cases, i know i am clearly out of range for a wifi network, such as the top floor of my office, yet it picks it up and connects without data since i assume i am out of range. For now i just manually control it as its pretty rare, but fir sure not something i have ever experienced before.

Agreed this is what I am seeing.I have disabled power saving and the other option to turn off data when sleeping and yet periodically the wifi just drops as I am viewing some wifi video streaming. It is weird I switch off the WiFi and use data and all is fine. I do not know if it is an incompatibility with my router. That's why I posted here to see if anyone else is seeing similar issues.
Also is there a way to set a manual Ip? was wondering if that may help as have heard issues of other phones having issues with DHCP via wifi.

I ordered a new AC router and will see if that works better and if I still get wifi drops. I am hoping it is my old cheap router giving me issues.

Well I got the ASUS RT-AC66U and now the Wireless 2.4GHZ works great but the phone will not connect at 5Ghz, so much for AC that only operates at that frequency. I heard other people are having this issue as well from my searches on this forum and the web. Kind of sucks that my router has the latest firmware and still has this issue with this phone. I did notice that there was a beta firmware on Asus's site but I am iffy on trying a Beta Firmware on my Router when all other devices are working great and so is the phone on the 2.4ghz. Great range with this router as well. Sucks that I can not use the 5Gz on the phone though. Tried on 2 other Devices that support 5Gz and it is working great on them. I gave 2 different names for the 2.4Ghz and the 5Ghz to tell them apart, but no go on this phone.

here's my take on the whole wifi thing with htc one. either the wifi chip is too picky or it's too new for the older routers. i couldn't get a wifi to stay connected using my old D-Link DIR-655 router from years ago. All other devices had no problems except this phone so that's a bummer. I then picked up the Asus RT-AC66U and immediately flashed the latest beta firmware. Performance and range is flawless on the 2.4GHz band for this router. 5GHz works as well if i'm close but it just doesn't have the range of the 2.4GHz for this phone so I've been sticking with 2.4GHz.
I actually wanted the just announced RT-AC68U but couldn't wait any longer as there's no eta on the release for it.

I used to have a Belkin Wifi-N router cost me about 40$ on sale and it used to work with my old Samsung but could not connect and stay connected on my One (Single was not to strong on top floor of house as well). It kept dropping WIFI after a few minutes on One and was really annoying. The RT-AC66U works great at the 2.4Ghz and I am tempted to try the Beta Firmware that you are using but I hear it slightly drops the range on the 2.4Ghz and all my other devices (WD-TVlive) are working great streaming 1080P from 3 floors up (Routers in Basement). Question for you, since you flashed the Beta firmware and can connect at 5Ghz are you hitting the 400Mb speed when you connect at close range. If you click on your connected network on phone it shows you the connection speed.

unfortunately with the beta firmware on 5GHz band, the fastest i am able to connect with this phone is around 87Mbps and it still feels slow compared to 2.4GHz. mind you this is me checking the speed by standing right next to the router with my phone. on 2.4GHz the fastest speed i can get is 72Mbps but the range is great. i hope asus is able to release newer firmware that will help increase the speed and range of this router at 5GHz but it's probably not possible. i still think it's the AC chipset/driver in this phone that's preventing the wireless from achieving maximum speed. in comparison, my dell latitude notebook is able to connect at 450Mbps at 5GHz with on wireless N. THat's with the intel wifi chipset which has always been imo the best in compatibility and performance. i look forward to the day when i can rock a smartphone with intel all in one chipset.
I am also connected at 72mb and at 2.4ghz it connects great. I am going to leave it like this. I find the range on the Asus router is amazing. It sure beats all other routers.
Anyone else having issues?
I mean why can't I just turn a new phone on followed by turning on wifi and connecting to my known network without issues. I'm finding myself googling the f* out of wifi connection problems related to the Note 5.
Am I alone here or are others just as frustrated with wifi connections as I.
Verizon Note 5 64gb
Beats me. My wifi is working fine. I added my network, haven't touched it since. Netgear r8000 router, connected on the 5ghz band.
No issues with my WiFi on my T-Mobile Note 5.
You might want to check out WiFi manager.
That App would probably help with your issues.

I had WiFi issues on the first setup ..would find the network and connect and disconnect automatically . since I got the phone 1 week automatically go. . there have been 2 updates here in Singapore. . now all the bugs have been fixed including the WiFi issue
None of my devices has ever had dropping problems with the WiFi (iPhone, iPad, S6 Edge+, notebook and a wifi extender). But since I bought the S2, it is randomly dropping connection, with no pattern.
Which model did you buy?
SM-T719
It's the latest 8" with qualcomm
Yes I'm having the same issue in the T713 model but not in the T813 model, both are th Qualcomm model
Im having the same issue with mine. I called samsung support and they were no help.

Same issue with SM-T813, found a temporary fix.
Just replaced my SM-T810 with a SM-T813, and ran in same wifi drop issue. My girlfriend and her SM-T813 ran in the same issue too. It happen randomly from 3-4 times per hour to one time in 2 hours. I foud it only occurs on 2.4ghz network connected in N. It happen to me on 3 differents routers, DIR-868L REV B 2.04, DIR-868L Advanded Tomato, DIR-628, and Asus RT-AC68U stock with latest firmware. If i configure the 2.4ghz band to G only, no issue, also, the 5ghz band got no issues at all. Hope this help your issues while waiting for a fix from Samsung.
Thanks for the tip. I can confirm that 5ghz wifi works perfectly. Hopefully samsung will fix soon.

Valid information, ndompierre!!
I´m situated in Germany and bought a S2 8.0 (SM-T710, Android 5.0.2) last week.
One of my use cases is watching movies which are stored on my NAS. With my "old" Nexus 7 (2013) everything worked like a charm.
But with the S2 I ran into the issue that the movies stucked once in a while.
At first I thought it had something to do with the apps I am using, BSPlayer and MX Player Pro (which work fine with the Nexus).
I even downloaded VLC Player but the same behaviour occured.
Then I downloaded the movie locally to my Tab and deactivated WiFi. Bingo..played without any hiccup. Proof enough that everything is fine with the apps.
So I googled a bit and came across this WiFi issue others also have. After I followed your proposal and changed the 2.4GHz band in my router from option "802.11n+b+g" to "802.11b+g" everything works fine again. No dropout during the whole streamed movie.
So I hope, too, that Samsung will come up with a WiFi fix soon.
Interesting. I've noticed that since updating to MM, my T810 seems to frequently switch to my other wifi networks on me. My preferred SSID is 2.4GHz N mode. I never catch it happening when I'm using the tablet, but after going to sleep and waking it up it literally seems always to be on the "wrong" network if I've previously switched it to the "right" one (not sure if it hops off the other 2.4GHz ones as well). I'll stick wiht 5GHz for the time being!
Saw Spotify dropping out a few times this weekend while connected to a wifi Hotspot. Haven't had a chance to test it at home yet. T817W model running Marshmallow.

I bought the T719 LTE 8.0 inch Version last week and also hab wifi connection problems, but only when in airplane mode. My Router is am fritzbox 7490 at 5ghz. Currently without any reason the wifi connection is stable. When in LTE mode the wifi was always stable.
I have the same problem too. (T719 LTE model) I was wondering would the radio mode consume battery faster instead of airplane mode?
P.S. I still have problem but i am on airplane mode. Have not tried yet radio mode
disconnecting wifi
I have the t819 bought it last week constantly dropping wifi had the s3 tablet before never happened also have ipad and does not happen. Sent samsung an email but still waiting for reply
My T813 does this, but only on battery when optimization is on. When it's on the charger, or I turn power optimization off, it stays connected pretty solidly. I suspect a fault in the power management.
It is kind of annoying, as I have some clients that have to be restarted every time the network drops.

How do you turn optimization off? Battery optimization can be turned off on my tablet, but it has to be done app by app (one at a time)
Hi
I received my 3T yesterday. I am having issues with WIFI
WiFi network drops frequently and the mobile data is used for some time and then WIFI is connected again. See attached .. This happens even when moving between rooms of my house
I think this happens when the mobile wifi changes from 5GHZ to 2.4GHZ when I move away from router
I have updated to OxygenOS 3.5.4 as soon as I received the mobile
The signal strength of the 3T is also very low
I have a 2 year old moto X 2014 and the moto beats the 3T at every place in my house
The signal strength and the wifi speed both are better in moto X
I have checked at various places
I have wiped the cache. Tried changing 2.5GHz to 5GHz
Changed Channels.. Tried all the things that I could find on the internet
But still problems
So is this a hardware problem and should I ask for a replacement? Or is this some Software bug which can be resolved
My router is ASUS RTN66U and a lot of other devices work seamlessly on that router and hence pls dont suggest to change the router
Awaiting replies
Regards
Ajjaykummar
I think this is a bug related to 3.5.4. On 3.5.3 my WiFi worked a lot better, but LTE Advanced is faster on 3.5.4. You can try a custom rom or downgrading, there's also a leaked OxygenOS 4 rom out.
Do you have wifi issues now when u have 3.5.4
I don't want to install new Roms. As I may have to return it in case this is a faulty piece
I'm having the exact same problem. I stream a lot. Very annoying when music video or gaming gets disconnect so often. My Galaxy Note 4, & s6 works fine.

yes, it started on 3.5.4.
here is a screencap of the issue
You can see in the screen cap that the mobile is connected to ASUS5 (5GHZ)
Then as I move away from the router the signal weakens and then the wifi disconnects .. and then it connects to ASUS (2.4GHZ)
Earlier it was connecting to ASUS but with a exclamation mark (without internet).. I waited for 15 minutes but it did not connect
Then I would connect if I switch off and on the wifi toggle
After that I did a factory reset and now you can see the screencap
It connects after a minor delay.. So is this alright
My other mobile - Moto X 2014 simply switches instantly from 5GHz to 2.4GHz and vice versa.. not even half of second is taken on moto x
Give the device a static IP use 2.4 network as it's more of a long range band. I tend to use the 5 band for stationary stuff. My WiFi works fine but all my home devices have a static IP.
This are the things that I did
1) Factory reset
2)Use Legacy DHCP client (under Developer options)
3)Disable Smart Wifi switcher (Advanced Wifi setting)
4)Static IP
This seems to solve the disconnection issue .. I still feel the wifi signal is weak compared to my other devices
Hope this helps someone facing the problem

I had the same Problem on OOS 3.5.3/3.5.4/4.0 at the OnePlus 3T.
I tried every Solution on the internet and nothing worked for me.
But after i looked into my Router-Setup i saw the DHCP Section where i selected 'Renew DHCP every Day'
>>> Screenshot what i mean - imgur.com/KakQX3i.png <<<
After that it works perfect. No connection-issues anymore.
mine is already one day..
I thought it was resolved... but again I noticed slow wifi speeds
thinking of replacement
haven't had the phone long enough to experience disconnects but wifi is definitely slow...
I have a 200mbps connection, getting 160mbps on desktop with LAN cable, 110mbps on my OPO, only 50mbps on my OP3T....
all tested through speedtest with the same server location.
OP3T is chinese version flashed with oxygenos 4.0.1
edit: later tested again with OP3T getting up to 90mbps but still 20 less than the OPO
I have same issus like lajay. The Galaxy S7 from my wife works perfekt in the same Network!
