Wifi keeps disconnecting - Galaxy Tab S Q&A, Help & Troubleshooting

Hello, I recently updated my t-700 to Lollipop and since then my wifi network got worst and worst.. (the problem was present also with KitKat).
Every 1-5 minutes the wifi networks disconnects and reconnects after 10 seconds.
I've the very same problem with my galaxy alpha and this problem only happens with my university's WiFi (eduroam, enterprise settings). This is a huge problem for me since I live in campus accommodations.
I think the problem is the 5 Ghz band, because with my previous tablet, a nexus 7 2013, I was having the same problem but there was an option to disable the 5 Ghz band and use only the 2.4 Ghz.
This is not possible with samsung devices.
My tablet is not rooted or modified in any way.
Any suggestion to fix that problem?
Edit: I've no power on routers or network settings

I'm having the same problem with my Galaxy Tab S 10.5. Mine is also not rooted. It was working just fine since october when i bought, but just now in may wifi keeps turning off by itself. Anyone has an idea how to fix it?

wifi network detection issues

I recently bought new note 10.1 2014 edition wifi only version. Out of the box it had troubles in detecting my home wifi network. I managed to fix by enabling and disabling wps connection settings from my ZYXEL wifi router. But the problem appeared again in a month with just one reset of the router. My galaxy S2 and S3 have no trouble finding my network so I don't understand why the tablet can't. Both the phones actually more networks than the tablet actually so it's not limited just for my own router. I really hate Samsung for this. I believe the issue is not about hardwarehere.
S2 is running on neatrom latest version. S3 is running on original firmware 4.1 from Samsung and is not rooted yet.
I have been running into similar wifi problems without a real solution. I've noticed it had helped a little too connect to a 2.4ghz network versus 5ghz. But that cuts out the new wireless ac band that this tablet wad suppose to work with.

After your suggestion I digged into the settings of the router. I could not find the option you mentioned but managed to get it working by changing to 802.11b+g+n to 802.11b+g. I am sure this was not a problem before but helped for now.
Anyone else with similar troubles..I wonder if only mine is buggy piece...
i just got the note 10.1 2014 edition wifi only version and i am having problems with the wifi i have a rooted phone which i use the hotspot and my wives phone is connected to the hotspot and my laptop i have no issues with it but just as soon as i connect my table the 4g signal cuts in and out all the time any ideas on what i problem could be
This is a problem with the Note 3 too... Samsung seem to screwed the wifi drivers badly. I found going to wifi, hitting settings again brought up an advanced menu and unticking "scanning always available" and "auto network switch" fixes it a bit...
Thanks for the information I will give it a try
Hi. Recently set up with a new wifi hub and phone, laptop and tablet (Note 10.1) all connected fine. Even more recently the signal gave up in certain parts of the house so a lot of settings were changed, including network name. Phone and laptop found them fine and have been working ok but tablet can't find the network at all. No way of downloading apps onto tablet and diagnosing the problem but save changing the settings again and risking the signal going back to rubbish in the top of the house, is there anything I can do to figure out the problem?

I was having issues with my WIFI also. It wouldn't connect on 2.4 GHz but would on 5 GHz. The performance wasn't great and I would get the connection isn't stable message a lot. I tried a bunch of things on my router and finally just did a factory reset on the router. I can now connect of both 2.4 GHz and 5 GHz. My connection speed has also improved dramatically. I didn't think it was a router issue since the Note 3 WIFI issues are pretty well known to be a problem. In my case, doing a factory reset on the router helped my problem a lot. For reference it is an ASUS RT-AC66R
I used the app WIFI Analyzer from the play store to monitor the signal strengths. Since doing the factory reset on the router, I only see the connection is unstable message very rarely.

I had same issues I thought phone was junk but it was my router. So I upgraded and set my Wi-Fi channel manually and not I am without Wi-Fi issues

You can turn off the option in the wifi settings that lets the phone auto disconnect from wifi if it thinks the wifi signal is weak or unstable. I sit 10 feet from my wifi router and it used to go back to the cell signal randomly. I disabled the auto switch option and no issue since. My wifi at home is very strong so I think its a bugged setting or something.
"Your network connection is unstable, so we in our smart thoughts have decided to disable it. Kiss my Gritts ". Ho Hummmmm
click dont show this option again
Wifi
If you are sure your WiFi is good, then go to WiFi settings,
1) Switch OFF Auto network switch
2) Keep Wi-Fi on during sleep: Always

Man, wish I had known about this... My Nexus 5 and 7 (and office iPhone 5S) all have excellent Wifi connection at my home.
I bought Note 3 to use the Wi-Fi calling feature and this caused me to missed multiple phone calls. Apparently, when the Note 3 is on Wi-Fi calling, it sorts of "disable" or reduce the cellular radio signal - zero bar shown on my Note 3 - all calls and SMS go through Wi-Fi. When the Wi-fi drop, it takes sometimes for the Note to establish cellular connection and that's when I missed the call.
Not to mention I am browsing happily or streaming Netflix and BAM.. wi-fi dropped and everything stopped.
If the Kit Kat upgrade fixes this issue AND not bring anymore problem (as evident from numerous threads), I would have upgraded to Kit Kat already.
Dammit, over the course of browsing for an hour, the wi-fi disconnect over 5 times.
What the hell!?

Nexus 5X can't find any wifi network

So I bought a Nexus 5X 2 days ago. When I first started the phone it was running Android 6.0.0 and it didn't have issues. But a update for 6.0.1 showed up and I downloaded it. And then the issues came. It cannot find any wifi network... The problem isn't from my network, because every other device finds my home network and all the neighbors network, but the 5X doesn't find any... I tried factory reset, network reset, cache reset, nothing helped. I even tried Android N beta and for a moment it fixed the issue, but this morning the wifi problem occurred again. I sign out from the N beta and through Mobile network it managed to download the last stable version(that's what google is calling it) - 6.0.1 and the problem was still there.. after some restarts of the phone and some factory resets, i thought the problem was gone, because it managed to find every wifi network in the area, but after i used the phone for 25-30 minutes, the wifi problem occurred again and ever since... So, is this a common issue with the phone, or the android 6.0.1, or is my phone a defected one? Should I go to the store and ask for a replacement? Or will the next phone do the same thing ?

Hi something similar happened to my 5X (6.0.1). It was able to find wifi network but I was not able to use internet even-though internet was working for other devices. I have restarted phone but my phone stuck in to WIFI Obtaining IP address...
I have restarted my router and problem resolved. Happened two times. Might be some bug in software.
I'm currently facing this very same issue, no WIFI networks are showing up. I've already flashed latest N preview with same results, funny thing is that this morning was working just fine. But I had to reboot the phone and now it won't detect any WIFI Network at all.
I'm starting to think I have a failed unit, but since I'm outside the "US" I can't send it back for warranty repair. So I'll just keep it and keep restarting until it's fixed again. This is really frustrating, never happened to me with any device I owned before.

Is it every wifi or just your wifi?
If it is just your wifi, try factory resetting your router after recording the settings, or try removing some entries that my be using NVRAM.
I've seen cases where the router runs out of NVRAM to record the DHCP entries and that causes connection issues. It doesn't show up for other devicdes because their entries are already stored in NVRAM. It is just the incremental new device you add that triggers the problem, so you naturally think the problem is with the new device since all your other devices work with the router.
my solution for wifi not found/working
i´ve upgraded from the nexus 5 to 5x.
i had a really weird issue with my wifi.
only found my wifi when i was not in airplanemode. so i read 1000 of articles about the wifi of the n5x.
just the standard blabla. so i did my own research
while my n5 and my n7 + 2 laptops had never issues my new 5x didnt find my wifi. i really thought it was an hw-issue. but it wasnt.
i am using a fritzbox router. newest update, made a reboot, rebooted phone. nothing happened.
then i checked my wifi channels, set it to manually and instantly found my wifi. i really never expected that the channel got such a big influence. may be the latest update brought a bug for the wifi channels or the hw is just not capable of some channels, dunno. but this is what helped me and it was nowhere mentioned in any forum.
tl;dr
try to change your wifi channel of the router.
edit: btw i found the 5ghz while the 2,4ghz wifi didnt work. but i wanted the 2,4ghz wifi to work because of the short range of my 5ghz wifi.
atm i am on channel 8 and i got no problems with the 2,4ghz wifi network

I don't know about Europe, but usually in the US we only use channels 1,6,11 to prevent overlap.
This is because there is overlap in the channels so you can't really use the in between channels due to too much interference. If you are the only wifi transmission in your area it is fine to use any channel, but if there are others and they are using standard channels for no overlap/interference and you are using in-between channels, your signals are probably going to interfere with each other.
When everyone is using the set channels, then they can negotiate properly and everything works better. With overlapping frequency bands, the negotiation doesn't work well because your signal sometimes looks like noise to the other device.

Hi, thanks for your help but unfortunately it's every wifi... it just hangs on "Searching for Wi-Fi Network..." and stays there...
I already talked with LG and they asked me to send the unit for repair, but I'm no in the US anymore (I was for a short time of period and that's when I bought this phone). So that would not be an option, right now I'm only using 4G and trying to measure it, lol
Just another question, do you guys think I could use a WIFI external dongle through USB OTG? Could that be possible on the Nexus 5X?
Thanks for your help! :good::good:

Hi, thanks for the suggestion but the problem I'm facing it's with every wifi network around, not only mine.
I guess unit is defective, but could a simple reboot trigger this kind of behavior? This is strange, never happened on any device I've owned before. :crying:

Anyone else having WiFi randomly disconnect and reconnect?

I just got this phone yesterday and so far I just cannot get it to stay connected to my network. No other devices are having this problem. It basically just seems to constantly connect and disconnect from the wifi and also seems to constantly search for other connections as well. I've tried factory reset, cache clearing(which never works as it just red triangle error's me), reset the router, tried to change settings in phone itself but nothing seems to fix it and it's making it impossible to use at home. Anyone have any suggestions?
Same thing here. I went in and turned off all the wifi in battery power saving exclusions. Ain't been home long enough to try though.
I'm having this same issue! My prior daily (S9+) didn't have this issue, and my Pixel 2XL doesn't have this issue. I could be right next to the router and it still does this. Doesn't seem to matter if I'm at home, work, parents house, or a cafe, it still randomly loses connection. Same with my Gear S3. Just randomly loses connection. It's pretty annoying, and I hope they offer a software fix. Yes, I factory reset the phone and it still occurs.
I noticed this only with the 5 GHz band... I will contact LG about it today...
Yeah, I'm having the same issue. My router broadcasts both 2.4 GHz and 5 GHz on the same SSID. Last I'd heard, Android wouldn't connect to 5 GHz in that circumstance, and my G7 appears to continue that trend.
But it still disconnects from the network all the time.
Sadly I have the same issue. I have different SSID for 2.4 and 5Ghz band, and as devil_tear says it's fails only with the 5ghz band. I did a factory reset but issue stills there.
Did you found a fix for this issue?
Had the same problem. Solved by enabling wifi on the battery saving power exclusions in the battery menu.

Thanks a lot for this tip.
Had the same problem, was burning through my 4G data at a rate much faster than on my Google Pixel.
So far, adding wifi to the power saving exclusion has seemed to fix the issue. Thank you!
PS: Does any else find the wifi signal on this phone is weak?

Great suggestion
Tried the suggestion here for adding WiFi to exclusion. WiFi on 5ghz still disconnects and reconnects every few seconds. Only way to keep it connected is putting it on 2.4ghz.
Tried the suggestion with reboots, factory reset, adding WiFi to exclusion and then connecting to the network. My g7 will just not work with it.

Have seen this also, in my case it happens when I am a bit far from the router, it may be the router not having a strong stable connection so the phone see it doesn't have internet. In the points I experience that I have a 5Ghz connection of 0-2Mb but I have maybe 2 bars of connection. Share your opinions to try to understand the problems.

For me I would say it happens more if I have 2-3 bars but nonetheless it happens even 3ft away from the router eventually. what's odd is my note 5 stays connected, my computer, and other phone stay connected on the 5ghz band. All these devices are in the same location so I'm pretty dumbfounded especially considering this is a newer phone than the note 5 lol. I hope it can be fixed with an ota update

I have the same issues. I sent back the first phone for a replacement thinking it was the issue. When the second phone arrived it was working perfectly and then it happened again.
I noticed this happened after I took whatever software update was offered. I went as far to switch providers with different equipment (fibe to cable) but same result.
Made specific 2.4ghz SSID for LG G7 and no issues.
I've never seen this happen. And my laptop and LG are using the same 5 ghz signal.
I think I remember the G6 doing this though

Just came back from my dad's house and I know it's a short test, however he has an Archer a7 connected after his dedicated provided box. I wonder if that can fix the issue?
I have the same issue.
it connects to 2.4Ghz networks fine but the range is very limited when I move to another room wifi reception decreases a lot. However my wife`s S9+ and my oneplus 6 works fine.
Main problem is when I connect to 5Ghz network it starts disconnecting and reception is even worse than 2.4Ghz. S9 and Oneplus connection is still fine at 5Ghz
I tried to change the 5ghz channels on the router but no luck and I exclude the WIFI from battery saving apps still didn`t work.
I have to use 2.4Ghz and the reception is not as good as other phones
Wifi seems stable for me, except wifi calling. That would crash at connection or even mid-call sometimes. I'd have to reboot to make or receive another call. Some sort of server error. Turned off wifi calling and no issues yet. Didn't notice Ed it anyway since 4g is really strong here.
After the newest update on my phone, taken today Oct 4th, 2018/my random WiFi disconnects haven't been happening at all on 5ghz. Also, the signal is about 3 bars larger now in the same location it used to be dropping out constantly. Hopefully it stays this way.

I was coming in to report something similar. I've got the US T-Mo version and just got the G710TM10K update yesterday.
WiFi stability has massively improved. Disconnects are almost completely nonexistent now. I haven't noticed that the signal bar is behaving any differently, but that doesn't mean a whole lot. The update was fairly large (over 400 MB), so I could see new firmware playing a role.
Could anyone still on G710TM10G post their data from Software Info to check if the baseband has been updated? Here's mine from 10K:
Android Version: 8.0.0

Problems connecting with 5 GHz wifi since few months

Hello.
For some time my Note7 does not connect directly to my wifi in the 5GHz band.
When I turn it on it takes forever for my wifi to appear in the list. Even when I get home, it can take up to 30 minutes.
I reinstalled HydraROM and also tried old backups. In the beginning it worked but the problem came back.
With a App my wifi does not appear, but i can see others in 5GHz.
It works on all other devices.
Does anyone have a solution or idea why that is?
