Galaxy Note 2 Wifi issue

This is pretty strange so I thought I'd check here with people.
I got my new Sprint Note 2 today. When I was at home it connected to my wifi network and worked fine. When I got to work I connected it to our wifi network and the internet won't work. If I turn off wifi internet comes back.
Here's the kicker, I have my old iPhone right next to it connected to the work wifi network and it is connected fine to the internet. This is definitely going through wifi as I no longer have a data plan on that phone.
I checked with our IT admin who said that there is no need to "accept" a device on our wifi network. He also rebooted the network for good measure. After both phones lost the network (from the reboot) and reconnected the same thing happened. No internet from my Note but internet works fine on the iPhone. Restarting my Note doesn't fix the problem.
Any ideas? Thanks.

I have the same problem. Need help too.

Is the wi-fi sleep mode on?

Very odd. I've had no such problem at home,work or university

My network admin created a second wifi network to connect to (I guess our router supported it) and when I connected to the new one I got internet.
If it helps others try and solve the issue he tried pinging the IP address that my phone was using and said that he could only send information but not get anything back.

Try changing your wifi channel config in the router.

Hi, I've got the International version N7100 and experiencing weird wifi problem. I have tried to reset my wifi router and use static IP but it doesn't solve the problem. Btw, the problem is whenever I connect my Note 2 to wifi it would lose connection after a while then messes my router and connection of my PC to router as well. Never had this issue until I brought the Note 2 home a week ago. I had to restart my router and turn off my wifi on Note 2 for everything else to work. My iPad, iPhone and PC are all doing fine when Note 2's wifi is off.

I used to have terrible problems with my Virgin Superhub which all went away when I changed the security settings to WEP hexidecimal from WPA2-PSK (AES). Laptops and phones would have intermittent connections all the time which a reboot or channel change would sort out but only temporarily. Give it a whirl.

I've been experiencing the same problem. It's especially annoying when I try to download big size apps on Google Play ( > 1 gb) because it will stop any moment and i will have to re-download it over and over again. It never happens when I connect to school wifi but it just happens when I connect to my wifi at home. Weird. Nothing is wrong with my wifi at all because my other computer is always connected 24/7 without any problem.

I have a similar problem on Omega Ron v5.0 with latest Andrei kernel. The phone gets stuck sometimes in getting IP address part or have disconnects. It's annoying.

Afraid not.
I did that after other efforts failed but still have to go through same issue every now and then. This is not a permanent problem but something that occurs at least once a day for me.

Also having Wifi issues with GN2 from Sprint
I got the GN2 on it's release date (this past Thursday) through Sprint. Got it home got set up, connected...everything worked beautifully.
After a couple of hours, downloading apps etc. I noticed it had stalled. Turned off WiFI and used the network to finish. Turned back on WiFi and Voila, action again, but a few hours later it stalled.
I first made sure all of my settings were in agreement. No sleep mode or anything like that was enabled. No power saver either.
Couple hours goes by, WiFi connectivity stalls (even though it shows a full signal) I contacted TWC and made sure it wasn't the modem/router. I changed the wifi channel, tinked with the bandwidth... everything worked...an hour later it stalled. Called Sprint they said I had a dud, took it back, exchanged it, got the new one... SAME ISSUES. YEsterday I connected to my Church network HOPING it was an issue at home, but not so. After an hour on the network it stalled.
Contacted Samsung today and they have had no complaints according to them so i said I'm happy to be the first... If anyone finds a fix please let me know.

Do you have any solution yet? I have the same issues with 2 different networks. I already contacted Samsung, but they only say I should do a reset of my device and read the setup instuctions for wifi. I'm still in contact with Samsung and hardly try to get a solution.
Stay tuned, I'll post any news I can get.

I'd prefer it to work with the stronger encryption of WPA2 rather than WEP.

OP: it will be great if you could add a poll to the thread as that way we can see whats the percentage of users are experiencing this issue,
Thanks

I had this issue with my S3, but never with the Note 2. What i did in that instance was reinstall the OS and that seemed to have fixed the issue. Hope this helps!

Same issue here. Connect wifi and I'm able to hold connection for as little as minutes at times. Turn back on 4G and I'm fine. If I re enable wifi straight after it works intermittently. This is true of both my home and office wifi. So I'm lead to believe it's the phone.

Hi,
Almost the same thing here. everytime I go out of my home and comeback the wifi network seems to work but no internet access. I have to stop and restart wifi then it works.
very strange issue. ok I have a work around but I'm going to open a ticket to Samsung.

Same issue - connects for about 30 seconds
I've tried on different routers. Other devices (iphone, ipad, S3, etc.) all work fine. Sees the wifi network. connects, then disconnects and TURNS OFF WIFI. I can't figure out how to go to service mode to see if this is a timer issue. I've tried on both G and N networks. using a verizon fios, actionteck router (and netgear). Also, will not remember the password credentials. tried router reboot and fidling, etc. Driving me nuts. any suggestions ???

[Q] Suddenly can't see my 2.4GHz wifi.

Hey all
I have a T-800 with IronRom on it. Everything was working fine for almost 2 months now. Starting yesterday, my tab is unable to find my 2.4GHz WiFi, but is still able to find/connect to my 5GHz WiFi or other 2.4GHz networks (public hotspots).
Other devices see the 2.4GHz network fine, and can connect to it. I've just rebooter the router and payed closed attention to what happened. Once the router is online, i can briefly see the 2.4GHz network, i tried to connect to it and my tablet asks for the wpa2 key. When i entered it (it's pretty long) i clicked connect, but the network was already listed "out of reach" by then.
Some more info:
I have rebooted all related devices
Tablet CAN connect to 5GHz network
Tablet CAN'T connect to 2.4GHz network (out of reach)
Other devices (laptop, phones) CAN connect to the 2.4GHz network
Tablet CAN connect to other 2.4GHz network
I have tried a Wifi Analyzer app, that also can't see the 2.4GHz network.
What could cause this or how could i diagnose/fix this issue? Any help greatly appreciated!
Thanks a bunch in advance!

Perhaps some program you've installed recently has made changes to the system or settings that's prohibiting connection?
You seemed to have established there is nothing wrong with your network, and even the device can use both bands...
I would backup, reset the device and see if its still an issue.

Thanks for your reply! I have performed a reset and the problem persists. I have contacted Samsung support and they say it's a hardware issue and i should send it in.
The repairs are outsourced to Dynafix (can't post URL because I'm a new user). Any idea on how they handle rooted tablets with a custom OS? Should i tell them upfront?

You should get it as far back to stock as you can... ie - odin a stock rom.
If its indeed a hardware issue then it shouldn't matter but don't give them that reason.

I managed to fix the problem with the suggestion of a friend. My 2.4GHz connection's channel setting on the router was set to automatic. I assigned it a fixed channel and it immediately popped back into my available networks. Weird problem, but I'm glad i didn't send it in for repairs because they would've charged me for it.

Had the same problem and it was rom related. I changed the rom and coud enable auto channel again in my router...

Mesh WiFi issues after latest update

My wife has the S8 and I have the S8+. After the latest update (July 9-10'ish) both of our phones are having problems with our Mesh WiFi, but not our non-Mesh WiFi. We don't have issues with the connectivity to the actual WiFi, that always stays connected, but every few minutes, we'll get an exclamation point next to the WiFi signal meter, and our Internet connectivity drops. When I check WiFi connections during this time, it shows "Internet may not be available". Then, after 1-3 minutes or so, it's working fine again. While this is happening, none of our other devices have any problems with Internet connectivity.
T-Mobile had me boot into Safe Mode, and the problem didn't happen at all in safe mode. So, I did a master rest, and with just factory apps installed, it was happening again. T-Mobile asked me to wipe the cache partition. While trying to boot to that menu, my phone went into a boot loop, then after trying several different button combinations, it just turned off and wouldn't power back on again. So, T-Mobile sent me a replacement. Since receiving the replacement, I have not installed the update, and I have not had the problem on my phone at all. But, there's still my wifes phone. T-Mobile tells me I'm the only one having this problem, so they don't know what the solution is.
Our Mesh WiFI system is fairly new, so I kept the old WiFI active as a fall back option. There are no problems when connecting to that SSID, so I'm thinking the update has caused some issues when jumping between access points on the mesh system. I was also thinking maybe it's a double NAT issue, since my modem doesn't have a true bridge mode option. (My modem hands my mesh WiFi router a 192.168.1.xxx IP, but my devices that connect to the mesh WiFi get a 192.168.0.xxx IP) I tried putting the Mesh WiFi in the DMZ and making sure it gets the public IP. That didn't work. The WiFi manufacturer had me open ports 500 & 4500 to the WiFi router. That didn't work.
Does anyone have any other ideas for me? At the point, T-Mobile is telling me that it's my WiFI because it doesn't happen when connected to the non-mesh WiFi. But, it didn't start happening until the last update, and it's not happening on my replacement phone. We rely very heavily on WiFi calling, so this has been problematic. Obviously I can connect my wife's phone to the old system, but we don't get full coverage in our house from it, which is why we went to a mesh system.
I welcome and appreciate all suggestions.
Thank you

I have the same problem with my non-mesh Google Wifi router occasionally. it's annoying.

I'm having the same exact problem with my S8+ and my netgear orbi, all was good until about a month ago, and I've tried pretty much everything, and the exclamation point still comes every few minutes. I can't wait to get rid of this phone honestly. And I've had EVERY Samsung phone to date, and this one has given me the most problems by far. I am on my 5th S8+. HURRY NOTE 8!

Running Luma mesh network... Have the same issue on my S8+ after the update...

Thank you! I just changed that setting. I really hope that works!

Other fix is enabling guest network on your router. It worked for me with Netgear Orbi.

I have an orbi and the above fix didn't quite fix my troubles. After enabling guest mode, then what? Use guest mode? Or does just the act of enabling guest mode change something? Thanks in advance.

Wi-Fi Verbose Logging
Yep! This is a problem the carries and Samsung have chosen to ignore so far. I have the exact same issue with two S8's in my household. Everything, all devices, LG, Apple, HTC, Google, Amazon, PC's, etc., including the S8's worked on our mesh wifi network until the two S8's took on the latest update. After that point neither S8 device would consistently work properly on the mesh network. While all other devices, including a Note 5 and Samsung Smart TV, among a plethora of other devices, continued to work flawlessly. It is definitely tied to the latest update on the S8 devices. I reset the wifi, the phones, etc., including factory resets but that did not solve the problem. Verizon sent 2 replacement phones and we have not allowed the latest update to load on the phones and the replacement phones are working perfectly! The latest software version that screws up mesh wifi connectivity is: NRD90M.G950USQU1AQG4. Beware. So far, neither Verizon or Samsung will acknowledge the issue. Only after hours of trouble shooting and persistence on my part about this issue being a well documented situation in on-line forums did they respond by saying they found one case similar to mine but they did not see this as a wide spread issue. Well, for anyone with a mesh wifi network, this is a big issue and irritating as heck! Come on Samsung! Own up to the issue, support your customers, and fix the problem. The evidence that there is a problem at this point is pretty convincing. All one has to do is go on-line and search the issue and bam, there it is. All somebody at Samsung has to do is take an S8 load the latest update and try it on a mesh wifi network. Really try it that is... It work at first but as soon as the mesh network moves the device to a channel or frequency that is less congested, the device will lose connectivity. Sometimes it is sporadic but eventually it becomes a more persistent problem to the point of uselessness. Either put out a patch or push out the wifi portion prior update for us to revert back to. Don't call us liars and ignore the issue. Hard to achieve customer loyalty and retention with behavior like that. I've already had to muddle through the Note 7 fiasco with the 3 recalls and final discontinuing of the device itself. Samsung, don't leave me hanging again.
UPDATE:
Turning on the Wi-Fi verbose logging did not solve my issue. It seemed to work at first. However, after a few minutes it said it was no longer connected to the web when trying to load some very common url's. However, this time there is no "!" next to the Wi-Fi signal on the S8. It now just stops working. Wish I hadn't let it update on the replacement phone. Again working just fine before the NRD90M.G950USQU1AQG4 update.
Help....anyone!?

After enabling guest-network, forget the main SSID and connect to guest-network. If you "allow guest to see each other..." you will be able to see other devices, like printer, Sonos, Roku, etc.
I tried the fix above and did not work for me either. Going back to login in in guest-network.

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.

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
Android Security Patch Level: September 1, 2018
Baseband Version: MPSS.AT.4.0.c2.9-00045-SDM845_GEN_PACK-1.160685.1.163435.1
Kernel Version: 4.9.65
Build Number: OPR1.170623.032
Configuration Version: 2.350001

WiFi issues: can't connect to any network anymore [T800]

In the last 6 months or so I have been experiencing frequent wifi issues, regardless of the custom ROM I'm using. Usually some time after a new installation I am unable to connect to the networks I normally use (my home network and the one at work which uses a proxy server). No matter what I do (clear cache, factory reset, change ROM...) the problem persists. In settings a number of random messages are given: secured, disabled, authentication problem, etc. Every now and then I can get a connection (never at work though) but it doesn't last long. Any help for troubleshooting this would be appreciated. I hope it isn't hardware failure since I'm still enjoyng this tablet after all these years!

Mine started having wifi issues off and on a couple of weeks ago. The wifi started to not turn back on after waking it up, at first just in manually turning it off and then back on seemed to work. Last Friday it just wouldn't stay on at all. I would go to the wifi in settings, it sometimes would get stuck saying turning on. I finally did a factory reset on it, it at first seemed to fix the problem, even spent a couple of hours trying to get everything set back up. Then the problem returned, it just keeps turning the wifi off, if i can even get it to turn on at all. I was going to try and use my phone as a hotspot through Bluetooth (not sure if i can or jot, never tried before), but even the Bluetooth won't stay on. So Sunday, after spending way to many hours fighting with it, i went out and got a new tablet.

Have you tried using the Samsung Kies app to flash the latest stock rom, Dont use Odin or other non Samsung approved flashing software.
I have had my T800 for over 4 years and had no real problem with the wifi connection, But i have heard that there can be compatibility problems with some wifi routers, Also try changing the channel number on your router, Auto channel was giving me poor connection on my PC, I ran the inSSIDer wifi app and it said to manually change my wifi channel to channel 1 the clearest channel as other wifi and bluetooth and wifi dongle even you smart gas/electric can cause interference., auto was picking channel 13 for some reason and it fixed my problem.

Thanks, but since it's the router at my workplace there's not much I can do on that side. Question is, are there any specific steps I can take to verify if it's software-related or if the wifi module is just gone?

Wifi and Bluetooth both use the 2.4ghz frequency, So they can interferer with each other and can cause constant disconnect`s, I have seen this many time, Use 5.0ghz on your T800 if you can, Or disable Bluetooth.
Does your wifi work OK on other brands of router?, Or is it just the one you are using at work.

It's kind of tricky to answer: let's say the times this issue appeared it always stareted at work, but then also at home I couldn't keep a stable connection. Once the problem starts, I get no connection at work at all and very difficult connection at home (meaning it does connect intermittently).

UPDATE. After other attempts and a complete restore of stock firmware, I have both wifi and bluetooth not working, constantly "turning on...." but never activating.
