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 !
Hello ive had my note for 3 days now im on criskelo v11.
Wifi at home connects and when i go iut it switches to 3G automatically.
However when im back home my GM does not reconnect to wifi automatically (ofc i leave wifi on all the time). Is this a bug somewhere or is this feature simply not available on android devices? I just switched from iphone to android
thanks all.
By the way i have an app called Wifi manager maybe this is interfering?
It should connect automaticlau mine does i was usinh criskelo till yesterday
Do not use any kind of managers.. Use native features.. And update your router firmware

msedek is correct. Use the stock setting built into the rom. Your wifi will kick on shortly after getting within the range of your router.
Hi all. i have a problem with my note. on some instances if i try downloading large files(for games or navigon maps, or just browsing on some sites, etc) after 10 15 seconds the wifi adapter shuts down/resets and the connection is lost. the adapter restarts and connects to the wifi in 2 3 seconds but is very frustrating to try downloading something many times before succeeding. anyone else has this problem? i searched the forum but didnt find anyone else with this problem. any ideas as to what is causing this problem?

Re: note wifi disconnecting
Hmm. Try changing the router wifi settings to transmit only b/g and retest.
Had the same issue, please tell us what version and kernel rom you are using?
->I had only when using CM, on stock GB and the XXLSC roms, I did not encounter this problem (also with cm 10.1 I seem to have a stable connection again)
**I do want to note, that it can't be possible to have a worse connection when on CM vs TW, but I have experienced it this way. So I can onlyh draw my conclusions from that...(I don't have any developer knowledge whatsoever)
Re: note wifi disconnecting
I would start by un plugging the router and plug it back in.

Try this:
Dial *#0011#*
Press the menu button on service mode screen
Select wifi
Turn "wifi power save mode" off
It seems like this is only working on samsung roms. I'm on CM10.1 and I have to dial *#*#0011#*#* to access the service mode.
Also there is no wifi entry in the menu.
Re: note wifi disconnecting
just downloaded a 700 +mb file with no problem. i set the router to b and g only. seems it was the frickin router. tx a lot to all 4 ur support.

CHanging to b/g works
Hi,
I have router DIR 855 and had the same issue with my note. Wifi kept disconnecting whereas all the other devices at home stay connected. So it was clear that Note was the one that had the issue. Changing the 2,4ghz to b/g setting helped but I would like a stable connection on my 5 ghz band and that one keeps disconnecting. Any idea how to fix that? I am using NAS and the speed is much better when using 5ghz instead of the old crappy 2,4ghz.

For me too 5GHz is not stable on note... Why not use the router on Auto and then use the settings on NAS to use only 5GHz
Please explain

Hi,
Can you please elaborate on how to do that?
My router has two different bands and it cannot switch between the two. What do you mean by NAS setting?
Depends if your router can run simultaneous dual band.
Wicked wakelocks and WiFi issues
Just yesterday I started having wicked WiFi issues, where both 5GHz and 2.4GHz networks would connect, then immediately disconnect, then connect again a few seconds later for it to just do the same thing, over and over. It keeps sending reports everytime it does it. I haven't factory reset though, but I'm going to have to.
Also, I keep getting insane wakelocks. Android OS is the worst, causing 7h+ of wakelocks in a 10h day. Google Play Services is pretty bad too, around 6h+ in that same 10h day.
Anyone else having major issues like this with their Note5? I have the N920W8 model, which I can't really find any info about anywhere
Im having similar wifi issues. Initially trying to connect to my 5ghz N home network (wpa2 psk) connect attempt, drop, connect attempt drop rinse and repeat. After a while it connects and stays connected, however, connecting to any web pages is painfully slow (like a super slow dns lookup), and i frequently get failed web page loading errors or failed to download apps from teh app store. Wifi calling is useless in this state. The same thing happens on an open hotspot network at work (2.4ghz) and the corporate (5ghz n) network. The note will ususally eventually drop wireless and force me back onto LTE. I looked at my data counter after just 3 days, and had used 27gigs of LTE, which is more data than I've used on tmobiles network since last year. Had some spotty wireless issues with teh note 4 rev 3 5.1.1 as well prior, but only had that phone for about 10 days before swapping for teh note 5. Prior to that I had the nexus 6 and no wireless issues on the same networks.
J'ai le même problème avec le 5g damn!!!
Luckily i have a dual dualband router, I set up the alternate AP 2.4ghz N wpa2 psk and the phone appears to be working fine at the moment on that network.
I ended up factory resetting and it appears working for now. A static IP address (DHCP reserved in the router) seemed to help.
Another issue I have though is when disconnecting from WiFi and connecting to mobile data, it seems to have DNS resolution issues until I turn data off and then back on. Not sure if it's the phone or the carrier (Wind Mobile) but it's pretty consistent
Not seeing these issues on my W8.

I'm just having dreadfully slow WiFi on my att model, but it doesn't drop connection
Dial *#0011# and click "wifi settings" from the menu at the top right corner. Turn off power saving mode and restart the phone, see if that does the trick.
If not, google search "note 3 wifi issues" and/or "note 4 wifi issues"and look for answers there. In all likelihood the problems that are being experienced with Wi-Fi on the note 5 are similar to the Wi-Fi issues that the predecessors experience when they launched.

It's Lollipop. It's a known bug in the software since Nov 2014 and Google hasn't addressed it. I too had issues with my WiFi when I first purchased it. But I found the work around. The bug is in the security software. The WpA2-PSK with TKIPS or AES which is a catch all, reeks havoc on our WiFi chips. It doesn't allow the phone to have proper DNS addresses resulting in severely slow internet or dropped connections.
Solution: Change your security standard to WPA/WPA2-PSK without AES or TKIPS.

Is that a phone setting or a router setting?
Hey guys,
I've got an Australian Samsung note 5 that has wifi problems. It started not working all of a sudden so i decided to go along with it but after a while i felt the need to try and make it work again. So i went into recovery mode and factory resetted (thinking that it would help) but then on the boot up after i came to the setup screen and found out that i was screwed. The samsung setup screen doesnt let you go past the setup screen without any wifi. Please help, i wanted to post a thread but im new to this community so i am restricted.
Thanks
p.s wifi networks can be detected but only when the phone is held right next to the router.
I fixed same problem of wifi, its a setting in phone, but you need to root phone, its system setting in system folder.
Any updates on this? Im running one 920g completely stock and another 920g with hybrid n7 port v9. Both have this same 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)
