[Q] WiFi reconnect problems - Galaxy S III Q&A, Help & Troubleshooting

Hello guys! I have a really annoying problem with my S3. I use tasker to turn on/off wifi with cell near feature. The problem is that when I get home, the wifi turns on but it won't connects until I unlock the screen. As soon I unlock the screen it connects. This problem I had it with all the roms past 4.0.3 and I really don't want to come back to 4.0.3 only for this issue. I have UltimaROM v8.1.1 Ifrit on it, and I tried with the stock XXELLA kernel, with the Phenomenal kernel and others I can't remember all now.
The setting "Keep Wi-Fi on during sleep" is set to always.
I made the "*#0011#" thing and put the WiFi Power Save Mode to off and don't make any difference. BTW after restart this changes back to ON.
There must be a solution for this. Thank guys for any piece of advice!

ICS Passion Wifi/Google Connectivity Issues

Hi, I'm currently using ICS Passion v10.6. I do not have a data plan, but am always connected to wifi at my house (router is usually about 3 feet from my phone).
Often my phone will lose google connectivity (wifi and signal bars will go gray), and often, usually when i leave my phone untouched for a while and then check it, i will notice that wifi had been lost and it does not reconnect until i turn the screen back on. I have the wifi sleep policy set to never sleep (keep wifi on: always), and the battery info says that the wifi is constantly on.
I was wondering if a different modem would help or if it is a bug in the rom itself or the kernel? My wifi and google connections would constantly be on 24/7 when I was running bionix v1.3.1. I've tried flashing the KB1 modem which bionix uses, but i get the same result.
Thanks for any help
Hey Devils,
I've had some of the same issues, aslo using 10.6. If I leave my phone alone for a bit it seems to stop getting notifications from data. The best example of this is I use Trillian IM and I can be chatting on it. Finish. And put it aside for awhile and not get any notifications and then when I hit the power button all of a sudden I've got 30 IMs waiting for me.
I have tried several different Vibrant ICS modems from this thread but they all caused big issues for me. some caused massive power drain but all of them caused my lock screen be unresponsive when I hit the power button and I'd have to wait for the screen to blink out and hit the power button again to be able to get access. The same would happen when I get a phone call, sometimes the screen just would not respond when it lit up for an incoming call. I think it was because it would start searching for data connectivity (so it seems related to the problem which makes me think it's not modem related)
In the end, I went back to the KB5 modem and my screen issues seem to have resolved. I may try Passion 11 soon and I'll post results if it helps, but right now I'm not ready to do another change on my phone.
-update- I just checked and saw that v12 is out now and has both a kernel update and an update to wifi. I'll probably try that tonight.
-update- I think this might be being caused by "Deep Sleep" causing the phone to shut down it's data antennas to turn of to save battery. I've installed "NStools" on my phone and set it to set the min CPU freq. to 200mhz to see if that will prevent deep sleep. I'm not certain this tool will work 100% on this build, but we'll see I guess.
I'm also running the Vibrant without data, using wifi to do things with the internet.
Since flashing ICS I haven't had any wifi issues on the two networks that I've used. Seems odd that you are now having them. Have you tried a different hotspot?
I have had issues sending text messages. I can place and receive calls, receive texts but can't send any. Have you had any of these issues? I'm curious if it has to do with the lack of data plan.

[Q] Data doesn't work, airplane mode is the only fix... any ideas?

I posted a question about this last week thinking it was a wifi problem, but it turns out it happens when I'm on data too, so it's an overall data problem... I'm just using wifi most of the time so that was the only place I had noticed it.
Occasionally my phone will stop being able to send/receive data. I'll turn it on and try to load a web page, for example, and it will just hang. Turning wifi on/off doesn't fix it, and turning data on/off doesn't seem to fix it either. The only solution I've found is going into airplane mode for a second. The frequency varies.. it seems to happen between 1-5 times a day, so it's pretty inconvenient.
I've read around a bit and it sounds like it's caused by the phone trying to get a 4G connection but it isn't able to or something, so it just hangs there and never lets the 3g/wifi connections get used (due to priority of connections or something). I almost always have wifi and don't care that much about data speeds, so if disabling 4g altogether would fix the problem I'm game (although I'd prefer another solution...). I tried the *#*#4636#*#* code to change it to GSM only (I read somewhere that that'll disable 4g), but it instantly reverts back to what it originally was, so that doesn't seem like it'll work. Is there another way to disable 4g?
I've got the stock ROM running Entropy's latest DD kernel.
I've had this same exact issue while running Miui and the Siyah kernel. What I've narrowed it down to is likely to be some sort of power save mode that kicks in when the phone goes into deep sleep mode. I haven't had the issue since I've ran the Kernel cleaning scripts and reflashed the latest Siyah kernel, but it reappears occasionally. On certain releases of Siyah, I've ran SetCPU at a minimum of 200Mhz to keep the phone from going into deep sleep just so it wouldn't turn off the cell radio.
Also, as a side note, I've had this happen when my phone loses signal. After so much searching, it will turn off the entire cell radio and display "Emergency Calls Only" until Airplane mode is toggled.
I had this same problem even back with my Captivate. Hoping ICS won't have the same issue. I'm running CM7 and Siyah kernel.
I am having the same problem Data wont work until i turn airplane mode on and off
I am having the same problem Data wont work until i turn airplane mode on and off.
Have you found a resolution?

[Q] WiFi Disconnects Regularly

Hi,
I just bought a Sony Tablet S, amazing device. The only problem I'm having is that when the tablet is idle, or the screen shuts down, the WiFi gets disconnected and it doesn't reconnect untill I open the WiFi panel in the settings app.
Now before you guys jump to conclusions, yes, I changed the WiFi disconnect policy to "Never (uses more battery power)". That hasn't helped at all.
Any ideas? Is this just with Sony S or a generic Honeycomb thing? Tablet hasn't been rooted as yet.
Try Advanced Wifi Lock Free. It works well with my tablet.
This issue seems to be a bug in Tablet S. I hope they'll fix it in the ICS release
Yes, already discuss here...
You need to install a must have application...
Advanced Wifi Lock
https://market.android.com/details?...DEsIm9wb3RlY2guYWR2YW5jZWR3aWZpbG9ja2ZyZWUiXQ..
Worked
Thanks for the app recommendation. It's working...so far .
I bought my Tablet S 2 days ago.
Though I have heard of this issue before, my new tablet does not have this problem, maybe Sony has fixed the bug.
p.s. I changed the wifi disconnect setting to Never.
I started using wifi advanced lock a couple weeks ago and it works great! Much better than making sure the screen stays on during all your downloading
...Although I've noticed a massive change in battery life. Typically I was always getting 7-8 hours of screen on (gaming) time out of it, with up to an additional 24 hours of time with it on standby.
Now I got about 13 hours standby and 4.5 hours screen on time with wifi constantly on.
All I'm saying is to have a widget for turning on/off wifi quickly, and leave it off when it's not in use. I didn't think that wifi made THAT much of a difference..but apparently it does lol (and that was still without autosync on either)
I uninstalled that and use spare parts instead. Advanced wifi lock was horrid with my battery grrr
I think is normal, because if you put your tablet in standby is because you're not using them so why you need wifi on?
When you turn on again the wifi will reconnect auto again
WPS Wifi Lock
I had the same issue when connecting at my house, If you have a WPS enabled routter, connect to you access point using WPS. At keeps the signal locked.

WI-FI problem

Hi everyone.. ive done numerous searches and it seems like most wifi issues are based on kernel matching.
if i go into my settings to turn on wifi. it shows that it turns on. with my old rom 1.1 predatorunity it would show turning on for like 5min then error now im running 1.6 and it shows ON. which is good news but then i go into it and it shows no networks. so i turn it off and actually go into wifi and turn it on from the wifi network and on the black screen backdrop just shows "turning on Wi-Fi..." and thats it.
how can i find out which kernel would work properly with my rom? (sorry noob question)
thanks

Issue with WiFi turning off. Anyone else has this issue?

Hi Guys,
I am facing a problem with the WiFi staying on on my brand new xz1.
In the Wifi preferences, under Advanced preferences, if i select "Never" for the option "Keep WiFi on during sleep", i have noticed that the Wifi turns off when the phone goes in sleep mode.
But the problem is that it does not turn back on. It stays off until i turn it back on.
Does anyone else also experience this or is my understanding off somewhere?
Thanks,
Prasad
No one else is experiencing this?
What could I be doing wrong or maybe i have set this wrong?
Any help guys?
Nope. I even noticed that since the latest update for my Z5 that wifi kinda doesn't work even tho it shows as connected after the phone has entered sleep. My XZ1 does the same. I'm assuming it's some new android power saving? My As soon as I unlock everything works fine again but if I'm downloading torrents or streaming movies to my tv i need to keep the phone plugged in so it doesn't sleep

If you select never it means: never keep wifi on during sleep = turn wifi off during sleep.
Select "always" if you want to have wifi always on.

The problem is your comprehension on the setting. Understand the setting and the options it is very clear once you understand the meaning of the setting.
You have set the phone to deny WiFi when screen off. Full stop
I experienced an issue on the first day where it would connect and then quickly disconnect while connecting to a public network. Haven't faced the issue since then again under the same circumstances.

Yes quite right.
I have set the phone tondeny wifi onky when the phone sleeps.
Does it bot mean then that when thw phone wakes up from sleep, the wifi should also turn back on?
That is how it works on other android devices.
But with xz1 once the device goes to sleep, wifi shuts down which is good.
But when i wake the device, wifi stays off. It does not turn back on.
Thanks for reading.

I see.
Not noticed anything like this.
However I have the same setting applied (WiFi off during sleep.)
So I'll test this later and report back.

It works for me dude. WiFi signal reconnects as expected when screen is turned back on after a sleep.
All I can say is Sony's OTA updates since even my z3 have always caused issues. Try a factory reset.
Thanks for testing it out and glad to know there is no issue.
Will do a reset soon enough and report back though it might take a while as i am travelling.

Try turning off data. There is a setting that keeps the lte active for faster network switches. I have same issue. Don't notice it when data is off.
I am suffering the same Wi-Fi issue. It is only since the recent update this has occurred. I've contacted Sony to no avail. It's driving me mad.
Same here (FW:47.1.A.12.145) WIFI router is with atheros chipset.
When phone is going to "sleep" wifi is switching off (even if it is set to not do so).
It seems that flushing cache partition is fixing it for some time.
