AW: Galaxy Note 2 Wifi issue

One and only working method for me is using the old wifi 4.1.1 folder.

Nothing else has worked until now.

I also tried everything including reboot, static configuration, turn off and on wifi, turn off mobile data or/and Bluetooth, changing whatever on the router, changing DHCP server, but the only thing worked is Turn on and off airplane mode.

Also recent update - after I did the trick with airplane mode it is now connects without any problems! I just came from work and had wifi there. And phone automatically connects to home wifi!

For me this is just great solution ever. Hope it will help to someone else too.

switch to "11 b/g mixed mode"

i tried all methods that everyone shared here, but nothing works. and then i try to change my wifi router setting.

before the network mode is "11 b/g/n mixed mode", and my galaxy note 2 won't connect,

but after i changed the network mode to "11 b/g mixed mode", the connection is working.....

maybe you guys can try my method.
[Galaxy Note II Q&A, Help & Troubleshooting] FloatingFatMan:
But in b/g mode, you lose a LOT of speed. Have you tried changing channels on your router?
[Galaxy Note II Q&A, Help & Troubleshooting] nick_will:
yes, i knew it, but what can i do? if i switched again to b/g/n, i could not connect to the internet.

i already tried changing frequency/channel from 2412 MHz until 2472 MHz (channel 1 to 13), but all are nort working for me....

so now, i just stick with b/g mode, wait until samsung releases new firmware for fix it.

I've had the wifi issue ever since the OTA 4.1.2 update in January.

So it's definitely NOT a hardware problem. I only wish Samsung

will adress it in the upcoming 4.2 update, but so far only silence.

After trying to connect to a wifi network 15-20 times, it usually

finally connects. But like so many others here, I experience

severe fluctuations in network speed. For 2 months now.

This SUCK BIG TIME, Samsung! Release a fix NOW!!!
[Galaxy Note II Q&A, Help & Troubleshooting] DARKKRAKEN:
I had an issue with the internet connection freezing and then coming back even though i had a full wifi signal, after lots of messing flashing lots of different firmwares, i happened too notice that the phone and my server were fighting over the same IP address, sorted that and everything is great now.
[Galaxy Note II Q&A, Help & Troubleshooting] heartagramm:
I too, have this connection problem to WiFi, and it appears everywhere. I've got a Cisco EPC3825 router at home, and my SGS1, SGS2 and SGGio have obtained connection to it flawlessly, every single time. Now I cracked my SGS2 screen and sold it, and bought Note 2 LTE version (GT-N7105) as a replacement phone. Stock 4.1.2, with stock kernel (I assume). Cannot connect to WiFi. Did some researching with the settings and found out that when I disabled mobile data connection completely, and then turn the WiFi on, it might get connected to the WiFi, no problem. Sometimes it still won't. After turning mobile data connection on, and then try connecting into WiFi, it will say "Obtaining IP address" and after that "Netwok disabled due to poor connection". So that was the first step of solving this out.

After that, I flashed a custom ROM and tested that. Same thing, didn't help (it was WanamLite, which is Samsung base I believe (I need FM radio)). After having problems, I decided to go and replace the phone (I bought the phone on tuesday). The seller tested the phone, and it connected flawlessly to an OPEN WiFi, and I told that it might connect fine sometimes and sometimes it won't. Then I noticed that there were some password protected WiFi networks also, and told him to try and connect in one of them, if they knew the password. He tried connecting to a password protected WiFi and the problem occurred. So they decided to give me a new phone. After that I went home, and tested the WiFi in here, and same problem.

Today I found the fix. I put static IP to the WiFi config, and it will connect just fine when the IP is foretold for the Note 2. So the problem is "fixed" for my own network, but it won't help much, as I would have to find out other WiFi networks IP before I could connect to them (like at school etc.). So it is a partial "fix".

Using the *#197328640# and turning manually WiFi power save mode off doesn't help at all for me.

My phone is SGN2 N7105 (GT-N7105XXDLL5), with kernel 3.0.31-679347, JZO54K.N7105XXDMB2.

I'm hoping that the phone doesn't need to be sent for servicing, as it's obviously a software bug for Note 2. I had 4.1.2 on my SGS2 i9100 too, and it never had this problem.

EDIT: I managed to connect into WiFi when assigning a static IP in settings, but I can't download anything. :) So that's it for the "fix". Waiting for some official, as I wouldn't wanna lose my warranty. I believe N7105 cannot be flashed completely stock after root, it will always say custom rom count as 1, right?

My router was constantly kicking my Note 2 to 1 Mbps link speeds 5 feet from a Netgear WNR3500L v1. I stuffed Tomato on there, played w/ transmit power, used the "scan" option to find no one on channels 2, 3, or 4 (I picked 3). I'm now seeing stable 39 Mbps link speeds from 25 feet away! Here's the new speedtest.net app results:

I'm sure most of you have 1337 routers, maybe even 5 Ghz band capable, but here's the youtube I used to do it:

http://www.youtube.com/watch?v=VTZiHMyCr6Y

Keep in mind I'm in an apt w/ 20 AP's fighting for attention!

FYI, the 1st 2 runs are typically slow, but after that I see sub 60 ms pings and 25 Mbps download speeds.
[Galaxy Note II Q&A, Help & Troubleshooting] spystranger:
I'm facing unique issue. On my Note 2 when I'm connected to home wifi few apps like Play store, Youtube and browser are not working on but Whatsapp, viber, skype are working fine. And all these work perfectly fine at work wifi.

Can anyone suggest me what I need to do?
[Galaxy Note II Q&A, Help & Troubleshooting] tobbis:
I am just wondering, if this is a generally problem of Android for the Note II or if it just a problem of a couple devices. I am also having problems with the connection of my N7100 (4.1.1 Stock). It is just working fine and in the next moment the connection speed drops to zero (connection is still available). Switching WLAN off and on is fixing the problem for the next hours until it happens again. It has nothing to do with my router (Apple Airport Extreme). My iPad mini and HTC One are working without trouble on the same system.
[Galaxy Note II Q&A, Help & Troubleshooting] Televinken:
My GT-N7100 has the problem you describe, ever since I updated it to 4.1.2. When it was on 4.1.1 the phenomenon never occurred once. The biggest problem for me though, is that wifi only works approx. one out of twenty times. Also came with the 4.1.2 update. Since so many people are experiencing these kind of problems with the 4.1.2, it's a GREAT SHAME of Samsung to just "cover up" & ignoring all of their frustrated customers. Myself I haven't had a proper working wifi since January, when the initial update was released. The "updated" update that was relesed in the beginning of March (?) didn't change anything. This is my very first Samsung smartphone, & due to their attitude towards us customers, it will probably also be my last one from them.... Well done, Samsung! You really know how to handle customer relations....
[Galaxy Note II Q&A, Help & Troubleshooting] shimarayn:
Forgot to post here after I sorted my problem permanently with very little effort.

I am not claiming any credt for this fix, I found it elsewhere on xda and seeing as there are still people here looking for answers here it is.

You will need the wifi folder from a 4.1.1 rom and some sort of root explorer.

Using a file explorer with access to root files go to: efc/wifi

Replace the entire folder with the 4.1.1 wifi folder

Done.

Also please be careful when editing files like this as it can go horribly wrong if you delete the wrong folder etc...
[Galaxy Note II Q&A, Help & Troubleshooting] Sacrin82:
Hi. Try to enable and then disable airplane mode while you are connecting to your network. In somehow it solved the problem for me. Hope it will help someone else.
[Galaxy Note II Q&A, Help & Troubleshooting] Televinken:
I noticed this somewhere here on XDA before, but unfortunately it didn't work for me.

Instead I think I will use the guide from here to revert back to 4.1.1. Thanx anyway!
[Galaxy Note II Q&A, Help & Troubleshooting] R1K05@N:
The Airplane mode toggle always worked when my wifi or data got wacky. Sometimes I see LTE isn't working so I toggle the Airplane mode then boom LTE. With wifi I would notice my YouTube vids loading slow. I would speedtest and see I'm capped @ 6Mb/s but toggle airplane then I get my isp rated speeds. It seems to do this after a long while without resetting data for me. For the rest of you having issues beyond resetting your connection, good luck.

same issue on both 4.1.1 and 4.1.2

New N7100, stock rom had wifi not working, updated OTA to 4.1.2, same issue.

Tried every possible hint, no way. It just connected one time, after the first upgrade.

Back on 4.1.1 stock, same issue.

Tried to work on the AP settings, found maybe a combination:

1) set the WiFi channel to 1 (Europe standard) from 11 (tried with 8, not working)

2) disabled the wifi power saving.

Trying rebooting now... if someone wnats to test it on 4.1.2, thanks
[Galaxy Note II Q&A, Help & Troubleshooting] ArmyOfJuan:
Nothing worked for me as well, had to be right next to the router for it to be stable.

I created a 5G "N" SSID network for laughs and for some reason that worked. Doesn't have the range of the 2.5G but I'm up in running at home anyway. My wife has a GN2 4.1.2 bone stock and no problems, mine if f'd in the a.

Looks like the power output for the WiFi got nerf'd, be nice if someone can hack a way to boost the gain.

Problem Solved....

hi all....

i think i know how to solve wifi issue on note 2 4.1.2

after tried many methods and no result, i am thinking to bring the phone to samsung service center, and because i already rooted, so i have to unrooted and flash the counter.

then i download triangle away apk (http://xdaforums.com/showthread.php?t=1494114, and installed it on my note 2.

open the application and follow the instruction until you have option "reset flash counter", it will reboot itself.

and after back to homescreen, i just noticed that the wifi works, i still don't believing....

i checked it on my other wifi router and try to connected.....Voila.....it CONNECTED!!!

ha..ha...i am very happy, i just solved the issue by accident....:laugh:

the solusition is only reset flash counter to 0.

so guys, try my method and please kindly reported here......

thanks button would be nice:good:

Edit:

I am sorry, my mistake.

After several rebooting, the wifi issue comes again.

hi..i don`t see any thread that saying use reset flash counter/triangle away method to fix this wifi issue.

I already tried it and work for me, so i think not wrong if you also try and report the result here.

Just hope that is the solution....

Edit:

Sorry my mistake, after several rebooting, the wifi issue problem come again.

So as shimarayn said that is not the answer.

Apologies if my comment came across differently to my intentions. I am only trying to help those who are experiencing issues with their devices. Regarding my previous post, I am only trying to resolve the issue on a permnent basis. If the fix you mentioned works then by all means I encourage its usage. However every time you flash a new rom the issue in question will re-appear due to the fact that your counter will change..

Well guys, after updating to the new FW, released only today, wifi seems to be back in working order.

I've connected five times in a row, and not once failing. No dropping of speeds either. Finally!!!!!!

So my phone's now on the 4.1.2 N7100XXDLK7 JZO54K.N7100XXDMC3 firmware. Phew....

Update:

Unfortunately, it seems that the bug of decreasing speed after some time on wifi, is still there.

But now you can at least disconnect from wifi, reconnect again, & that way regain the speed.

We just have to realise that Samsung once again did a miserable job, with this new "update"

For those wondering whether the N7100 4.1.1 WiFi files would work on N7105, the answer is yes. And the 4.1.2 based ROM will have WiFi back as it should be.

Same problem here, waiting and waiting update, but still nothing. For now I'm using older kernel (with Omega ROM), so I'm not having that low speed problem after phone wakeup, but thats not normal, that I have to flash older stuff because in Samsung they don't do they work.

Viber settings causes WiFi to slow down on device wake up

Like all other frustrated Note 2 Users with the latest stock firmware, who were having pathetic WiFi speeds, even I was desperately looking within the settings, tinkering various WiFi settings etc. The only saving grace was when I had to keep the device's WiFi from going to sleep mode but that had a drastic impact on my battery life. I had chosen the compromise of always doing a WiFi off and on to get decent speeds.

However, today I think I had managed to find the culprit program that stalls the WiFi. I had a closer look at the settings of all the background process that run in Android and I found that Viber had a setting in its Wi-Fi sleep policy that will force the Wifi to be always connected. When I selected the "Use Device's Settings" option in Viber, voila, it worked. Now when I wake my device and test the wifi speeds, it is blasting at full throttle and no more struggling as it used to do before.

I have a Note2 and a galaxy S2 that both were exhibiting the same problem and after I changed settings in Viber, both the devices behave the way they should and no I suffer no more slow WiFi uploads and downloads. I hope this helps other Note 2 users.

Please post your opinions and thoughts on this.

Now a :) Note 2 User

^ Now there's a surprise... It's a 3rd party app rather than anything Samsung have done. This will be rather amusing if it holds true for other people having the same problems. My WiFi works perfectly and always has done. I do not use Viber.
[Galaxy Note II Q&A, Help & Troubleshooting] Televinken:
It has nothing to do with Viber.

Never was installed on my phone.

Hopefully, Sammy will adress it in 4.2.2

I was having the same issue and when I turned off Camera Upload on Dropbox everything is now dandy.

I didn't hand to turnoff power savings on wifi settings.
[Galaxy Note II Q&A, Help & Troubleshooting] Televinken:
My Dropbox camera uploads have been turned off all the time......
[Galaxy Note II Q&A, Help & Troubleshooting] FloatingFatMan:
So what DO you have installed? Odds are, it's something 3rd party.
[Galaxy Note II Q&A, Help & Troubleshooting] Televinken:
The reason I don't believe so, is that I have wiped the phone & made a factory

reset. When everything was all fresh, first thing I did was testing the wifi speed.

The result was very same as before; wifi speed decreases when phone sleeps.

So if the issue is 3rd party app related, it must be a "Note 2 default included".

Capisce...? ;)
[Galaxy Note II Q&A, Help & Troubleshooting] ron2k_1:
Did you set up Dropbox at that time? It seems that it is one of the services you set up at the beginning?

I'd install Elixir, 1 of those apps hogging up alot of cpu is the culprit. I think Elixir has a network monitor as well. You should check it or check any app that can tell you which apps are using most of your wifi bandwidth.
[Galaxy Note II Q&A, Help & Troubleshooting] Wajahat Khan:
I do think that it is a Samsung bug related to WiFi drivers as a third party app shouldn't be able to mess the WiFi. Ideally it should be able to cleanly override the default android settings but it is a clear case of buggy WiFi drivers.

I had also shared my findings with my other mates. One of them didn't had Viber on his Note 2 but was having the same problem. Turned out in his case it was the Facebook image upload app that was causing WiFi problems. He turned it off and the problem disappeared. So the bottom line is 3rd party apps cause conflict with the WiFi sleep policy and stalls the WiFi adapter. So Samsung should address this issue in the next update.

I am following this thread from long time,I was also facing same problem since upgrade to 4.1.2,So I flash stock firmware of many different region for short out wifi speed issue but no luck,finally I thought to give a chance to authorized service centre in U.A.E (Before giving I installed latest U.A.E Firmware) After 48 hours they return my Mobile with Note "No Problem Found",My Mobile was Factory Reseted & there was a same firmware version on that which I installed before giving to service center,ONLY DIFFERENT I FOUND WAS VIDIO CLIP SAMSUNG ORIGINAL "WONDERS_OF_NATURE" & SAMSUNG SAMPLE PHOTOS WHICH I WAS NOT GETTING WHEN I FLASH WITH ODIN,Now last 15 days I am using my mobile & not a single time I face wifi getting disconnected or reduce speed,I don't know what they did but one thing is sure my wifi problem is short out.
[Galaxy Note II Q&A, Help & Troubleshooting] Televinken:
Thanx for your information, laddies! It kind of confirmes that the issue is FW related, just as I thought/knew.

As I reported before, everything was Hunky Dory before upgrading to 4.1.2, and then the wifi issues began.

We will just have to have faith in Sammy adressing this crap in the upcoming 4.2.2. Otherwise I don't know

if I'll ever consider chosing a Sammy phone again. This is not the only shortcoming either. Remember that

Sammy showed the screen recording function in the GN2 marketing. Well, that function is still missing too.

:mad:
[Galaxy Note II Q&A, Help & Troubleshooting] ron2k_1:
I think they were showing the SNote recording feature. That is still there.
[Galaxy Note II Q&A, Help & Troubleshooting] Televinken:
I don't think so. On the release event/presentation, they clearly showed off a screen recording function. You were

supposed to be able to create an instruction video, for example. It's been discussed in several cell forums, & I'm

pretty sure that it had nothing to do with S Note. The general impression was that the function was supposed to

be implemented with a FW update "soon". That was half a year ago. I could be wrong. It has ocurred before...

[Galaxy Note II Q&A, Help & Troubleshooting] Wajahat Khan:
For me and 3 of my mates, WiFi issues were resolved by tinkering Viber settings, for another it was his Facebook image upload app. What about others? I am curious to know more about other users feedback on which 3rd party apps resolve their slow WiFi issues
[Galaxy Note II Q&A, Help & Troubleshooting] Atsco:
Same here, after 4.1.2 update WiFi speed ridicules, after phone wakes up from sleep. If I restart it, everything working fine to the next time phone goes to sleep. Tried everything, and same result, that you have. After factory reset first thing, that I did, was speed test, and result same. And tried it many, many times before had to learn flash ROM-s, kernels etc. Tried to disable Dropbox and many other pre-installed software's, no effect at all. And I don't use Viber. But after flashed old stock kernel (N7100XXDLJ2 ) Wi-Fi working fine. And all custom kernels working fine to. And with all ROM-s, that are not using Samsung kernel I didn't had that problem. So that's a fact, that this is Samsung kernel problem. So now everything working fine, but that's not normal, that I forced to flash old or custom kernel with new ROM! And I don't get it, why they don't fix this problem at Samsung!? Do they know about that at all? So many users turn they Wi-Fi off after every session, or have battery savers software's, example Tasker etc, that's turns Wi-Fi automatically off every time, when screen is off, so because that Wi-Fi starts every time in the beginning of the new session again, and because that they don't know nothing about that problem... I really hope, that after next update I don't have to flash old kernel again.

Only good thing is, that because of this problem I had to learn how flash custom stuff, and it's a all new world for me. There so many great Roms (using now Omega, and this Rom is amazing!) and other great stuff out there and it's great bonus for a every Android user :)
