[Q] WiFi Randomly Turning On - Verizon Samsung Galaxy S III

I have noticed that my Verizon SGS3 will randomly turn WiFi on. It will be off completely and just turn itself on then make a connection with whatever WiFi spot I have previously connected to.
Was wondering if anyone else is having an issue like this?

Chances are you won't get a response on this issue, since there are about a dozen other threads about it. I think it has something to do with a conneciton optimizer, however, Verizon didn't give users the ability to disable it.

[Q] Connection Problems

For the past couple weeks I have been having major connection problems with 3G & WiFi. It would just stop working, even though the bars would be there and show that it is working, but nothing would load. Normally have to turn off Wifi or data for a couple minutes and then turn it back on, or reboot, but even then it does not last that long.
I found on these forums and other places that people seem to have been having the same issue and was caused by the recent update from SuperSU and something it was giving permissions to called mksh. So I denied it permissions, continued to have problem, I went back to the older version, still the saem, I removed the program, and started using just normal Superuser, and the problem still continues.
I was for sure this was the problem, but the program is gone now. I know it can't really be the mksh by itself because it's part of the android OS. For awhile I thought it might have been my SIM card but quickly realised that well WiFi is a problem as well, not just 3G data.
Any one have ideas about this? It's getting really annoying and almost not usable.
BUMP, anyone, this is getting quite annoying. I have searched and done everything possible.
Still needing help.
I don't like bumping this all the time.
I have done all the searching I can, no one has similar problems, no one has any ideas?
Still looking for some answers.
I guess I am the only one.
service issue
toggle airplane mode and if it works call your provider it sounds like a issue with your service

What do you mean by toggle Airplane mode, when having the problem, turn it on, then turn it off, to see if service works again?
Yes that works, that is what I do most of the time, actually most of the time I have airplane mode on, and then have only wifi enabled.
Either way, how does troubles with WiFi as well as 3G connections mean a problem with my service provider? They don't provide WiFi
Anyone..

[Q] T-Mobile Tether, data keeps failing randomly

Hey,
I have a Nexus 5 that is set up to basically act as a router using wireless tethering. I live in an area where I constantly have full-blast LTE that is usually above 30Mbps. For about a month, everything's been great until this last week. Now, every few hours my data connection gets killed completely after anywhere from a few minutes to a few hours after tethering has been running. Data stops working on all tethered devices as well as the Nexus 5. Entering airplane mode and then resetting the WiFi tether fixes the symptoms, and if that fails, restarting fixes it.
I've disabled wireless_tether_dun (sp?), switched to IPv4 and I sometimes use a VPN that passes through all network traffic through the VPN. Even with VPN disabled, the data drop keeps happening.
I know there are so many things that can be going on, but has anyone else noticed this recently? I'm wondering if it is a hardware issue, a signal issue, or perhaps T-Mobile has changed something on their side of things that is killing my somewhat obvious abuse of their network.

I am having the exact same issue -my post- in a completely different place, only I have been assured it is completely fine to use my phone on the network in this way. Did you ever find a solution to this?

[Q] Wifi issue ! (Lollipop 5.1)

Hi All,
I got the Lollipop 5.1 OTA 2 days ago and installed it - everything went smooth and the phone working fine...
But I noticed that if I reboot my router (or turn it off / on again) the Wifi don't reconnect unless I turn on the screen (the second I turn on the screen the wifi connect normally).
I didn't have this issue with Lollipop 5.0.1
P.S.
I know that this is happening because I have a led on my router telling me if any of my Wifi devices is connected or not. And to make sure I also entered the router settings to see if my phone is connected or not.
Anyone noticed that issue with the new lollipop 5.1 ?
Cheers,
I think that your problem is not switching off the router. The problem is when your phone goes to suspension (screen off) and then it drops the wifi off.
My Nexus 5 with 5.1 is doing the same

I've got some similar behaviour here, both when updated from 5.0, and with a fresh install from the factory images. When I arrive at a place with known WiFi, the phone only connects once I turned on the screen. After that, it stays connected until I move out of range and back again.
It's probably a matter of responsiveness/battery life. The more it polls for networks, the more battery it uses. It should connect, even with the screen off, within a few minutes.
That being said, I have my wifi set to always stay connected, and I've seen it not connected when I turned the screen on, then connect a couple seconds later. So, there's that. Curious how often it does that.

That's what I suspected. Sometimes, the waiting game works, but I've had my N5 lying on my desk – where it usually gets full WiFi bars – for about 40 minutes the other day, still it did not connect until I turned the screen on.
Edit: Just now, my phone disconnected from WiFi when the screen turned off, which leads me to believe that this is all caused by the WiFi sleep policy. Could it be that Google messed up something there?

My "research" has led me to believe this is the case.
Anything in terms of a workaround?
I came across those settings in the developer options (see screenshot), especially the "Always allow WiFi Roam Scans" looked promising. Been playing with them, but so far no luck.
Hi All,
exactly the same issues as yours guys are happening since I received the OTA 5.1 and installed it !
I Guess something messed up with this new update in regard of the wifi... as you mentioned.
If you come across a workaround or a confirmation from "Google" please share.
Cheers,
(With almost everyone nowadays having data ..it is difficult to notice such a behavior due to the fast wifi/data switching)
I have seen this happen as well. My battery graph will even show a missing area for WiFi indicating it turned itself on and off twice within a few hours and then stayed on after that.
Google just now released LMY47I, has anyone had a chance to see if that version fixes our problem? Once I'm off work (in about 8 hours), I'll give it a whirl and report back.
Tasker will help you

Could you please elaborate on that? I'm familiar with Tasker, but I can't think of a way of dealing with this, since I'm not sure what actually happens with the WiFi. The settings appear untouched.

I'm sorry, but my phone is now in the service center , and press that I do not remember specifically . The idea is that when you disable wifi, a time interval is forced to connect to a particular network . Look presence on the internet , here is full of instructions.

Almost all of the changes on these different builds are SIM related for specific carriers.
LMY47I was only released to LGD821 devices with SIM cards from Indian and Australian carriers
Same problem here. I am slowly losing faith in Google. Get the frickin basics going guys!!!
Back to my 5.0.1 build.
I've gone back to 5.0.1, too. Pity, except for this I was pretty happy with 5.1. Maybe 5.1.1 will actually be usable.
Do you think it can be related to Issue 163350? code.google.com/p/android/issues/detail?id=163350
I have just reported that, but I'm still trying to understand if it just happens to me or what.

I think the solution is "use vibrate mode on". Get your device to vibrate mod and test it.
I am waiting for your feedback.

Wifi keeps disconnecting?

Hey, guys I just got my Pixel 2.
I connected it wifi but it keeps losing it. Only if I reset my router it will keep the connection for a while, but somehow when
I get to work or in the morning the same issue appears again. It connects but when I go to an app which requires wifi it drops.
I tried to change the channel but didn't work as well.
Restarting the phone won't help either. I also don't want to factory reset it since I want to keep all my data etc. I don't want to go all that bs.
Maybe I should have stuck with a new iPhone after all. Sorry for that comment, but I'm really frustrated
I don't want to give it back or some ****, I just want to fix it easily so I can move on. I hope I get some advice here.

this can help:
phone ::: Go to setting > wifi > advance > If there is Freq option then change it to 2.4Ghz
router (in case no option on phone) ::: go to Wifi setting of your router and disable 5Ghz. I can help more If I know model of your wifi router
:good:
I'm having the same exact problem as OP. I thought for a second I wrote the post. Would love to see if there's a solution. I don't see the option to change frequency in wifi settings. And this issue for me occurs on different WiFi networks.. so it's not just one router. Ugh!
Exactly the same issue here, which is what has lead me to this thread. It often happens that my phone switches to mobile data suddenly while working absolutely fine on Wi-Fi. I have tried almost every basic solution but condition remains the same. Also during that time it stop showing me my (saved) Wi-Fi in the Wi-Fi network available, while at the same time my same Wi-Fi is connected to all the other devices in my house. This needs a fix.
still no fix

ya my problem is still there. This phone is utter dog ****, to be honest. Still waiting for an update, but now I know..never buy a pixel again
Is Bluetooth on? This is what is causing my WiFi to be very unstable......

Wifi on but not connected most of the time?

So i know this is a widespread problem because im on my 3rd pixel 3 and i have exactly the same problem on every one.
When im at home wifi is on but half the time it isnt connected, but as soon as i poke about on the wifi settings it connects. Its like its in some kind of sleep mode or something. I end up using all my mobile data whilst indoors a few meters away from the router! Ive had a pixel 3 since it came out and just cant seem to fix this problem.
Please tell me its a well known problem and some one has worked out a fix
I have not had that problem, but you may be able to reduce the mobile data usage by turning off "Switch to mobile data automatically" in Settings, Wi-Fi preferences.

This is no a known issue and if you're on your 3rd pixel i don't think had anything to do with the phone. It's most likely an issue on your router side. Have you tried resetting it?
Are you by chance using WiFi which is configured as hidden network? This is typically done by checking the checkbook next to "do not broadcast SSID" checkbox.
If you are connecting to such network, there is a setting you have to check while setting up that WiFi connection. It is hidden in normal dialog and so it is easy to miss. This was the root cause for similar issue I have seen on my Android devices including Pixel.
Im not using a hidden network. The weirdest thing is whenever i notice its not using wifi as soon as i pull down on the screen at the top it will connect. like its been caught out lmao. was using the phone just now, an alert comes up to tell me ive used 2gb of data. so i pull down on top of screen and theres an x on the wifi icon, its on but theres an x (probably means not connected to anything) then a second later it connects. i dont click on anything it just connects whenever i pull the top bar down to check. its been happily eating my data while on sat in doors but as soon as i check that status it connects! its damn crazy!
This is exactly what it does every time without fail whenever i notice there is no wifi.
Fix your router bro

The x on the wifi icon means you are connected to the router, but the router is not connected to the internet. Like everyone else, I think you have a router problem. Rebooting the router may help, but it may be time to replace the router.
Where are you located? It could be that your internet is unable to ping google servers. I have that issue whenever I clean flash, but I am in China so that is why.
This is not a widespread issue and as almost everyone has said, you have a router issue. It's possible that your router "sleeps" when nothing is trying to use it but that's just a guess. My suggestion, get a new router.
