[Galaxy Note II Q&A, Help & Troubleshooting] kevingt01:
I know it's been months since you posted this, but did you ever find a solution. I'm experiencing the same problem and evidence in DD-WRT for my Note 2. At the end of this thread people talk about replacing wifi antenna and bending springs up a little to better the contact. I've done both with no improvement. One thing I do notice is that right after my phone connects, DD-WRT reports normal signal strength for about 2 seconds, then it drops off. During the same time of strong signal strength, my phone says the link speed is about 50Mpbs, then drops down to 1Mbps. Seems strange. I have an awesome lumia 520 backup go phone to hold me over for a few weeks if I end up having to send my n2 in to samsung. :)
[Galaxy Note II Q&A, Help & Troubleshooting] muchtall:
Yes: Hardware replacement. Sad, I know. Many here will claim that their special mix of voodoo will solve your problem, but I can almost guarantee you that your only real solution will be a replaced mainboard.

Your symptoms sound identical to mine. Most likely the WiFi chipset transmitter has failed. If you still have your GN2 under warranty, get that sucker back to stock (w/ counter reset) and get it back to Samsung under warranty replacement ASAP. Since having my mainboard replaced, I haven't had any issues (well, with WiFi anyhow). Once my 2 years is up with Sprint, I'll be replacing my Note 2 with anything but a Samsung product. I've been burned by their poor product reliability far too many times. I even recommended the Galaxy S3 to my wife and my father in law, and I've been regretting it ever since.

Good luck! Let me know how it works out for you.

Solved

Yesterday I got an OTA update to Android 4.3 and the problem is gone!

Went to work today and got back home (where I have a TP-LINK TL-WR1043ND router) and I still got full speed!

The whole device feels faster, and actually is faster. A slow app (nu.nl) runs much better now :)

This is amazing I have the same exact problem... I thought it was my ISP or that my router was dying.
[Galaxy Note II Q&A, Help & Troubleshooting] Jonasklam:
I have bad WiFi range on my Note 2. Actually so much that WiFi is basically unusable.

Let me make an example... My MacBook sees more networks than it can display on the sreen (between 20-30 networks) my note can find 2 and they have a strength of zero bars. :/

This is really frustrating, it also means that my tether range is super terrible.

It did have this problem when i first got it.. is my Note faulty, do i need to return it?

international note 2 here.. *knocking on wood* but my wifi connection is flawless.
[Galaxy Note II Q&A, Help & Troubleshooting] sayajoris:
I haven't had much disconnection since I last posted my issue here. I only put more distance between my wireless modem and my wifi router (about 2 meters apart, before it was less than a meter). I cant say for sure this is what made it better but since then I've had much fewer disconnects. Funny thing though I never had this issue with the old setup before I bought the Note 2.
[Galaxy Note II Q&A, Help & Troubleshooting] b4d5h0t:
I had wifi problems on my note and note2 wifi dropping out bad range etc.

I HAVE CHANGED MY ROUTER SECURITY SETTINGS FROM WPA2 TO WEP AND MY WIFI NOW WORKS PERFECTLY.

its worth it I now really enjoy using my note2 where as before it just aggravated me with the connection constantly dropping and being slow.
[Galaxy Note II Q&A, Help & Troubleshooting] FloatingFatMan:
Yeah, but you now have effectively turned your security off, seeing as it takes about as much time to break into WEP as it does to say you can break into WEP... :p
[Galaxy Note II Q&A, Help & Troubleshooting] nanotube:
I have the exact same problem! Well I am fine at my house but I got this problem when I went to my cousin house. I calles att tech support and they told me to try the *#0011# to keep wifi enabled at all time..... too bad it didnt work at all.

A side story...I tried the online chat with att before I called them. This web dude sent me a link to "how to setup wifi" on their website! Really, att?!?! :banghead:
[Galaxy Note II Q&A, Help & Troubleshooting] androidizen:
Ye I've had this issue as well, some devices prefer one or the other WPA2-PSK should be the most compatible for modern wifi devices. Also always worth moving your Channel ID away from default, less cross transmission with other routers on default channel 11 or 6.
[Galaxy Note II Q&A, Help & Troubleshooting] parrot5:
Run a survey app to check it. With everyone trying to be "smart", it turned out that the default channel is the least congested at my place.

@ Sayajoris and PastorDroid

I had the same issue like you guys. Get home, connect to my wifi, internet will be good for few minutes and then internet stall at around 200-300 kbits per second (ouch! very painful bandwidth speed). And I will register pretty much much no internet or very low bandwidth on any other device connected to the same network my Note 2 was connected to. As soon as I turn off wifi on my Note 2, all systems come back on and no issues whatsoever.

So I knew the issue was with my Note 2. I did this and since then no issues.

1. Delete your Dropbox account (Settings>Accounts>Dropbox Account>Delete)

2. Go to Settings>Applications Mananger>All

3. Delete Cache, Data and Uninstall Updates from both Dropbox apps (I don't know why there are two, but my phone shows two apps)

I haven't had any issues whatsoever, and my battery life has increased as Elixir 2 was telling me that Dropbox was using around 32-35% of CPU when wifi was turned on. I emailed Dropbox but they haven't answered.

Hope it helps you too. I know it sucks as you cannot use your dropbox but at least everything else will...

Maybe it was your pictures that they were uploading to Dropbox (g+ instant upload like feature), be sure to check account settings.
[Galaxy Note II Q&A, Help & Troubleshooting] ron2k_1:
That's the strange thing! I don't have any photos in my Dropbox. So why would Dropbox cripple my wifi. It's not that only my Note 2 got affected while connected to my wifi, but all devices got affected as long as the Note 2 remained with wifi on...

I don't know, for now I'll just won't use my dropbox app until the dev gets back to me with some feedback.

[Galaxy Note II Q&A, Help & Troubleshooting] SMARTPHONEPC:
I actually heard from someone working with an update with multi-view that it also includes Wi-Fi improvements (he says he works for Samsung but is testing out the update for AT&T not T-Mobile) which suggests Wi-Fi issues..which would be a Note2 deal breaker for me so Wi-Fi needs to work well on my 75/35 FIOS.

I remember when I first got my EVO I was having Wi-Fi issues until someone in XDA pointed out that I should go into Settings->Wireless&Networks->Wi-Fi Settings & next was like a hidden option as I had to hit Menu->Advanced->Wi-Fi sleep policy->Never

Let us know if setting the W-Fi sleep policy to "Never" helps..?
[Galaxy Note II Q&A, Help & Troubleshooting] nanotube:
I have tried it when calling att tech support. You can dial *#0011# and set the wifi "on" all the time. Unfortunately this didnt work for me. The rep just told me to exchange for another one.... not sure if that could fix the problem.

i just received my GN2 and it is awesome! I can't seem to keep a wifi connection though. even at home, directly in view of my router with my other android phone which automatically connencts, i do the following:

i turn on wifi on GN2.

i select the correct SSID

i punch in password.

it logs on and it tells me it can't access the internet through that AP?

am i missing something in the setup or configuration?

[Galaxy Note II Q&A, Help & Troubleshooting] heavyharmonies:
It appears to me that the GN2 has a crappy wifi radio compared to the GN1.

Sitting here with the GN-7000 and GN-7100 side by side, running the speedtest.net app on both devices, both to the same server, I'm consistently getting 80-100% higher throughput in both directions on the old GN1 than my shiny new GN2. The ping times are lower on the GN2, but the throughput is WAY slower.

Built-in throttling?

[Galaxy Note II Q&A, Help & Troubleshooting] meenaharish:
If your Wifi connection speed is fluctuating or reduced then also you get continuous disconnections. Frequent Disconnection happens if you browse with Low Speed. You need to upgrade / Top up your plan to moderately stable high speed connection. My wifi internet connection was reduced to Low speed browsing since i have exceeded the fare usage limit. Then onwards the internet connection was very much unstable. Now my wifi internet connection is very stable and working well after upgrading. Check your internet speed or service provide before you try with any other methods.

Hey everyone, was having a similar issue. In my travels through multiple bootloaders, roms, and rooting - something worked. A little bit.

I disabled Knox, and that seems to have improved the situation, but still not fully resolved. Drops once in a while. So far, it's better than what it used to be. Using CM13.0-20160907-unofficial-n7100 rom right now. Hopefully that helps someone else out there!

I had a problem with my brand new note 2 and wifi I would not connect for more than 30 seconds and it was driving me crazy. I tried just about everything and nothing work. Called Samsung who said I should do a factory reset and that actually work. Although it was quite a nuisance to reinstall. I have not had a problem sense.

This is extremely aggravating. ATT Note 2 model here. Not only do I appear to be having WiFi issues, but I appear to have connectivity issues in areas outside of WiFi that I previously had no issues with my old iPhone 4. Aren't these things supposed to revert to 3G when LTE is no longer available? So frustrating to have such a beautiful device in hand have continuous internet issues, when that's what I primarily use it for. Gonna try the factory reset and report back.

It tried me crazy too. I even intended to return GN2 because of Wifi problem. But when I used AT&T smart Wifi, it solved the problem. AT&T smart wifi may over ride the device Wifi, regardless you turn on or off the device wifi.

Use AT&T Smart Wi-Fi set to My Spots, if your carrier is AT&T.

Hmm, this is weird. I haven't had a problem with my WiFi, my brothers, or my mum's but we have a connection at work that works fine on my HTC One X and everyone else's smartphones but not on my Galaxy Note 2. It just won't connect. Doesn't refuse, doesn't give an error, it looks like it's going to connect but it just then goes back to not connected.

Funnily enough I had this same issue with my original Galaxy Tab 7" with the same WiFi connection. I put that down to having custom firmware on it and never really bothered to try and remedy it but my Note 2 is straight out of the box and should work but doesn't.

Bit lothed to do a factory reset if it's not gong to resolve it but it looks like it might be my only option.

More connectivity issues with Note II and wifi router

I have a N7100 and I am also having wifi connectivity issues. I have tried to follow advice in the thread (apart from a reset) but I am still having the same problems.

I have a broadband wifi router which I also use an iPad, win Xp laptop, HTC Wildfire S and Motorola defy through, all of which have been fine (using WEP encryption)

Unfortunately the note II seems to connect but then doesn't access the Internet. The phone's wifi page shows connection. It connects then receives and IP address but then the alert comes up that there is no Internet access. I also use fing which says that there is no wifi network.

I've downloaded the apps wifi manager and wifi analyser to try and get to the bottom of it but they both say I have good signal strength and are connected. Wifi analyser showed there was a bit of crossover from another AP router next door so I changed the channel to give clear air between us. I then reconnected all the devices and they all work -apart from my new Note.

Firstly is there anything you can think I can do to fix it. Secondly where are the logs situated which might let me diagnose it a bit better . I should add that sometimes it just works and can browse and download as normal, but most of the time it doesn't.

Please help if you can. Thanks

Was having the same issue with my ATT Galaxy Note 2. I did as some have said and connected using the ATT WIFI Hotspot APP and it is working flawlessly. I feel that that is trumping the Samsung default WIFI connector thus closing out of it if the password is not inputted in the ATT WIFI connector.

LMK if that works!

Still have the same problems. Already made a reset of the note2 and the router.

Bought a new router...same Problems.

Any other device is working fine.

I wrote an email to samsung customer support. They said it is a hardware error. But it is realy hard to believe. I guess it is a kernel problem.

Maybe it gets fixed with the 4.1.2 update.

copy down phone mac address, connected lan address

go to router, reserve that lan address with the phone's mac address

then enjoy your wifi.
[Galaxy Note II Q&A, Help & Troubleshooting] Jonasklam:
DId not work for me either..

My wifi problem is that the range on my phone is simply terrible.

My phone finds between 1-3 networks with zero signal strength, while my computer finds 20+ networks all with 2-5 bars of signal strength.

It feels like a hardware problem, because when I use tethering I also have to be within a few meters of the phone to even find it. And just a meter can make a dramatic change in signal strength. Anybody tried something similar?

I might try the factory reset.

the rest of the settings remained the same.

now i downloaded approx 1GB of apps from play store with a medium speed of 5 MB/s.

wi fi dropping issue on Note 2 i317

I'd like to share my wi fi dropping issue on my Note 2.

Mine is Galaxy Note 2 i317 with Jelly Bean 4.1.1. I did have wi fi dropping similar issue. I took two smart phones to Target, one is ICS 4.0.3 and the Note 2 is 4.1.1.

The 4.0.3 never has any issues with wi fi connection. But the Note 2 keeps on dropping the connection. I ran an application wifi analyzer to check the available networks. It turns out that Target has so many routers that are using the same ssid, i.e. "Target Guest Wi-Fi". There are channel 1, 6, 11, 2 Ghz channels, etc, as well as many 5GHzs. I did an alias for every available connection. Then I pick one of the stronger signal strength 5G and connected to it.

After that no connection was dropped.

The point is that you should try to connect to the strongest signal SSID so that the Note 2 won't keep on dropping the weak connection.

I have no idea why the ICS 4.0.3 can handle better than the 4.1.1 Jelly Bean as far as wifi is concerned.

But I do notice that on ICS it only shows 2.4 GHz channels. The Jelly Bean shows both.
