Note 2. Wifi connection problem. - Galaxy Note II Q&A, Help & Troubleshooting

My wifi was working very well. One day suddenly it went off. Initially I thought it was a connection problem, but eventually I discovered that the wifi toggle switch refused to start. It was stuck.
In a bid to correct it I even did a factory reset. But wifi issue remained.
Did everything mentioned in various YouTube videos. But in vain.
Then I installed Cynogenmod but same wifi issue. So went back to 4.3 stock android.
Not satisfied, I flashed kitkat 4.4 . Most of time wifi connection remains. But when I turn it off and then again on. It does not connect.
The only way I can resolve d issue is by switching off the phone, removing the battery 4 a minute and restart. Wifi works until I keep it on. Once I turn it off and turn on back again, it does not connect.
(My router and Internet connection are fine)
Removing battery every time 2 start wifi is nuisance.
Pl advice.

[Q] Wifi switching itself off randomly :(

Hi,
Yesterday I started having a strange problem with my Desire.
I was browsing the internet at home using wifi and all if a sudden it switched off the wifi.
I turned it back on again and it worked fine again for around 10 minutes when it did it again. I switched wifi back on again, this time around 3 minutes later it switched itself off again.
I have never had this problem before and haven't installed any new programs on the day it started. In wifi settings the sleep mode is set to never.
I rebooted and tried again, but out still happens. I have rebooted my wireless router, again no joy.
In desperation I factory reset, but it still won't keep wifi on for more than a few minutes.
I have a T-mobile uk desire which is stock and un rooted with stock radio too.
I sim unlocked it in march and have a vodafone sim in it
My wireless router its a sky one and is running on channel 13 as no one else locally uses that channel.
Has anyone got any ideas?
Cheers in advance

Still having this issue
If anyone can help or suggest things to try I would be grateful as I am at a loss now....

Wifi Forgets to Search for my Networks

Hi there,
My wifi is set up to use my home wirless network and works well when connected. The problem I am having is that when I have left the house for some considerable time and come back home, it doesn't seem to search and connect to the wifi again. I have to do it manually.
Had same issue but it is working now. Didn't do nothing to fix.
But my wife's wildfire is having the problem still.

I had the same problem after installing swiFTP.
The only temporary fix and to get a link to the WiFi was to restart the phone.
After removing swiFTP things went back to normal.

[Q] Bad WiFi software?

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.

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

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.
John.
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.
