[Q] Bad WiFi software? - Galaxy Note II Q&A, Help & Troubleshooting

For a few weeks we have 2 N7100's.
With both phones there are problems with WiFi.
Sometimes it won't connect, but worse, it won't disconnect.
WiFi keeps telling that it's connected to our AP even when we're out of town.
This way we won't get on 3G.
The only solution is to throttle the WiFi.
One phone is rooted.
One phone is un-rooted.
Both had WiFi-static, but I've removed that on the un-rooted phone.
This didn't help either.
Is this something in the software?

I've never had any problems with it on my Note 2. The first week i was stock and unrooted. Then rooted with ARHD and now i'm using ParanoidAndroid, still without any issues. Can connect to any network just fine, with password and without and disconnects fine too.
Did you try and do a reflash? factory reset? reset router? Perhaps some app is messing around with it.

Must be an issue caused by the modem/router, my wifi works flawless and is super fast mate.

The problem is on different AP's (locations, brands, settings) and both Notes had this problem from the beginning.
I'm wondering if it could be caused by having multiple SSID's in the settings of which some are working with static settings.

Try resetting the device.
i tried resetting to factory settings but nothing changed.
Have you tried reseting the router?
Are you having any Wifi issues with other devices? [if you have others]
Is everything stock or rooted? If rooted what are you running Rom and Kernelwise?
Try taking it to a friends or open wifi (like starbux) and see if you have the same issue. If so, get another phone (again).
You could try resetting your router.

I would reset your router just in case.
Your phone is stock right?
I don't think my issue is directly related, but my wifi won't auto reconnect out of the blue. Was working a few days ago, but now it just says scanning until I turn it off then back on and it will auto connect then. It's like it freezes in scanning. I wiped and retried sense and my CM6 ROMS and the issue persisted. Retried all that after flashing all new radios n wimax stuff, still no go. Now that I've done all that. My 3G data won't work. Forcing it into roam mode on vzw with 1x I don't get data either with data roaming enabled. Only data I get now is over wifi which still doesn't reconnect. F M L

I would suggest calling Sprint and they will probably replace the phone.
Sounds like a hardware issue.
not to be the forum police but you should ask these type of questions in the Q&A section not development in the future.
I would suggest either talking to sprint to get a replacement or downloading an app like wifi analyzer to see if you are getting a strong signal and it is having issues or if it just isnt connecting etc. over all you are probably going to have to get it exchanged.

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.
PD

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 ???

Weird wifi problem

Hey...I really have a strange wifi issue that I nor anyone else I have asked can figure it out. My galaxy note 2 connects to our wifi router with no issues. Works fine. BUT...occasionally it loses connection to the internet. It stays connected to the router...but not internet connection. After I turn it off on my phone and turn back on...its back on and fine.
B U T...that isn't all. WHEN it loses internet connection...it turns it off for EVERY other wireless device in the house. Laptops...cellphones, etc. Every other device will not be able to connect until I turn my wifi off on my phone and turn back on...or at least leave off. It never happens anywhere else...just at my house.
What is going on? I haven't a clue how to fix that nor what can be done...or why it is even doing this.

Yes. just did again. I'm just keeping my wifi off on my phone for now. I have a tech coming out to replace the wifi router since its theirs.
I have had similar issues ever since i flashed a 4.3 rom, wifi never works properly, did the param-4.3 odin flash too.
are you stock or on a 4.3 touchwiz rom?
Ok. I have replaced the wireless router...or I should say Charter did. They replaced it with the same model though...brand new. It still has the problem. I am on 4.2 btw and rooted...but no custom rom. Any other ideas.
You running a dual band router? Try only going on 2.4ghz band.
There are also some WiFi power savings settings you can turn off that should help also.
I had that same issue when i first got my phone in Oct fresh out of the box on 4.1. I did those changes and everything has been fine since

[Q] Wifi is connected but no traffic, WTF?

I thought at first my router was having issues, but that is not the case. I have confirmed zero router issues by using 3 laptops and 2 other phones (Samsung units) to connect to anything I want.
If I connect using my M8 (Verizon), it connects with no issue but I have no real internet connection. The signal strength is -40 so that is not the issue.
I have tried multiple restarts, multiple networks, and multiple SSID's. I even tried forcing it to 2.4 or 5 Ghz and nothing at all seems to work.
Is this a known issue? I am coming from a long line of Samsung stuff so I am not up to speed on the quirks with HTC stuff. Your assistance is appreciated!

Stock, custom ROM, etc?
This is a stock ROM with weaksauce root and nothing else.
Ok, so I just connected to the wifi at my office and it appears to be working just fine, but it took about 15 minutes form my phone to recognize that the network even existed.
I am pretty sure this phone is just a piece of crap. About 2 hours after my last post it started doing the same thing (at work). I just got home and did a 100% fresh reset of both my router and my phone to eliminate any possible configuration issues and it shows that it is connected on the phone, but the router is not seeing that it is connected... how the hell does that work?

Since you've determined its a piece of crap, sell it and get yourself a iPhone. Why bother trying to get it to work.
When you connect to your router what details does it give in the phone WiFi settings for that connection?
Also which router do you use?

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:
