Installed any apps or taken any updates lately? Is data working otherwise on your phone, like pulling up websites on it?

[Q] Wi-Fi randomly stops working (but I can still see it connected in the bar)

So my WiFi randomly stops working (while connected to the WiFi network and everything), and then, without me doing anything, a few hours into the day, it suddenly starts pulling email and working just fine.... then randomly -without me doing anything, stops working. Any idea what's going on with my phone?
Same problem here. Already had 2 atrixs and same problem with booth

This phone is an effing fail.
Remind me to never buy a non-Nexus phone (damn you Google for not including 720p recording in the Nexus S)
Many people don't realize that an old/bad modem will do exactly what you describe. I've had 2 in past years. The atrix issue will drop the icon. Check your modem.

It also happens at home when my laptop is working perfectly fine, but my phone, not so much. Hotspot is right next to both.
That does suck. Wish I could help. My atrix wifi flakes out but not horrible. A few seconds and it reconnects.

Wifi connection problems after using onavo data monitor app

Last week when the Onavo data monitor app appeared prominently placed on the market home screen I gave it a try.
Unfortunately it created a very annoying bug on my phone running JVU and Semaphore 2.5:
whenever my phone looses it's wifi connection for any reason it will not recognize and connect to available wifi anymore even if placed directly near the router with full signal strength!
The only way to get it connected again is switching wifi off and then on again...
I already uninstalled the app and did a factory reset but nothing changed. Probably it messed up some system files that don't get touched during factory reset.
As I'm in vacation now and don't have my data cable with me to flash a fresh firmware, is there any way to resolve this issue in other means?

Nobody here with any idea how to resolve this? It's really annoying as even battery consumption goes up very much when the phone looses wifi and auto connects to 3g.

I have no idea about your problem. I also have just installed Onavo on JVU firmware for a couple days, but everything is still ok....
So, I'm thinking the cause is from your router!! Why don't you try another wifi network?
Good luck!! ^^

Thanks for your answer! It doesn't depend on my router. As I said I'm in vacation right now and therefor using many different available hotspots, it happens on all of them... :-(

Any issues with battery drain and onavo? Cause it was sucking mine dry!! I thought it was semaphore's fault (i'm on icssgs 4.2) until i figure it out and uninstalled it. Now it is Almost as prior installing onavo. I have a feeling that it left some garbage behind though.
It definitely left some garbage behind and this thread is about to find out how to get rid of it.
Battery drain was and unfortunately still is very high on my device thanks to the non desired 3g connection instead of wifi...
Sent from my GT-I9000 using Tapatalk
Try to flash a new kernel again. It may help you updating some files that control wifi.
I used onavo for couple of days, battery drains. Its functions already in ICS roms, Less but good.

Thank you so much! That did the trick. The onavo garbage seems to be gone for good now.

You are welcome,
Could you please tell us about the battery usage. Do you noticed some changes in battery life?

Wi-Fi Lost!

Out of the blue I've lost my Wi-Fi capability on my S4.
I've restarted & turned off the phone to no avail. My phone shows up on my router's control panel as active as well as a couple of apps I have.
I've also forgot the connection & reentered all necessary info. Mobile connectivity is fine but as soon as I switch Wi-Fi back on, no tweets, FB notifications, etc.
Suggestions, ideas? TX

Are you on stock rom? Do other devices work on your wifi

I don't want you to root either. It sounds like to me that it's a hardware issue with your phone.
Well, even though my router gave all indications that it was picking up the phone I tried a hunch. Rebooted the router & Wi-Fi is back!

Help with connection issues and 4g

Hey guys I've been having horrible 4g and connection issue for a while on all roms even stock. YouTube is horrible and most things won't load or they take forever. My wife's s4 and daughters note 2 are fine and when they have strong 4g I get 3g. Any ideas.

I have an SM-N900V as well. I was having fits with 4G and wifi. My phone is rooted via vroot. I thought that might be the issue. I did a factory reset and did not restore my apps. I found the phone is still rooted but my connections issues were gone. I started recovering my apps via new installations. I haven't recovered them all btw. I had a ****load I didn't need. I do need an ad blocker and the only one that really worked was ad vanish pro. AVP caused the wifi and 4G problems. I can load it but as soon as I start it and load an affected app, down goes the wifi. I hope this helps and leads to further experiments. We need an ad killer that doesn't screw up the connections. AVP worked fine on my S3 until 4.3 was pushed out.

Random reboots after recent system update

Is any one else having issues with random reboots after the recent system update? This has happened 4 times now all under different random scenarios.

Are you using any themes, they can cause issues sometimes.

He probably disabled a bunch of apps and forgot to enable them when he updated his phone.
Sent from my SM-G935T using Tapatalk
Did you update OTA or ODIN?
It was ota and no I didnt disable any apps. I have noticed it seems to be happening when my bluetooth is on. Oh and I dont use themes just nova.
Sent from my SM-G935T using Tapatalk
Now that I think about it I wonder if it was that night mode that nova just added. Never remember the issues before that and it was turned on right around the same time as that system update. I turned that off to see if it happens again.
Sent from my SM-G935T using Tapatalk
Turns out nova beta and or night mode was the issue. Went back to stable version and removed night mode options. No more reboots and my bluetooth works like a champ now.
Sent from my SM-G935T using Tapatalk
So you think it's night mode. I'll t that. Had 4 reboots yesterday connected to BT listening to iheart. Today i was using Google maps in the car and not only did it freeze up it reset while i was driving.
