Help Weird issue with WiFi (disconnects suddenly)

Hey guys,

I bought an Ace about 2 months ago and about 4 weeks ago I started to suffer a weird issue on the WIFI randomly, it use to happen once every 2 days or so.

The issue basically is that I lose wifi connection, its like it suddenly disconnects from my home router and doesn't reconnect automatically.
I mean, ie, I leave my phone on a table or something like that, then I grab it, and after I press the home button for using it I notice that the Wifi icon on the status bar is not there anymore, while the Wifi option is set to ON.

To revert this, I have to go to settings -> wireless and networks -> wifi settings and just after that I see it start scanning for networks again and it connects to my home wifi again succesfully.

It is really weird, since my router is really close to where I leave the phone and I have never really faced any wifi issues on my linksys router with other devices such as my laptop and my previous blackberry or my girl's BB.

The really annoying part on this is that the majority of the times that it happens, it does it while I'm sleeping! :mad:
So when I wake up I found the wifi icon is not there and that my battery was drained like 40/50% (i think because of trying to connect/founding other wifis/whatever it started doing). So I have to go to wifi settings again to the phone to reconnect, or better yet, turn wifi off and turn it on.

And today I experienced it again, but in front of my eyes. I was laying on my bed writing a text message and noticed how the wifi icon suddenly disappeared... and again, had to go to wifi settings so the phone would scan again and connect.

Does anyone know what it could be ? I have the wifi sleep policy turned off since I experienced a random power off 5 days after I bought the device and I read it was recommended to have it set on "never". Besides I don't think this could be related to this since today I experienced the issue for the first time while I was indeed using it.

I have the stock rom, GB 2.3.4. I tried udpating the firmware but KIES says I already have the latest one (G5830LUBKPA).

Any comments would be really appreciated!

Thanks!
 
The ace's wifi is a real buggy thing, specially for non rooted phones, random disconnects, connected but no internet, not connecting to a particular router etc etc.
There are huge loads of problems with this wifi.
Go through this thread i am giving below, we discussed some solutions some time back, some methods worked for some people, some unfortunate ones did not get any working solution at all, look into it and see what works for you.

Good luck
 
Thanks man. I read that topic but those guys were experiencing another issue in which they couldn't turn Wifi on. I have never faced that issue yet. I'm on a different page with this one :(

Btw, I have my phone rooted.


edit: Do you think I should type *#*#526#*#* to re-install wifi drivers ? I don't want to mess the wifi completely :/
 
You can try 526 without any worry, it will only reboot your existing wifi drivers.:)
Or just reboot and see if that helps :p

You should switch to a custom rom if you are a heavy wifi users, no custom rom user has ever complained of wifi trouble, whereas this forum is full of non rooted users complaining of bad wifi.

Ok. Thanks man, I just did the 526 thing. Let's see what happens from now on.

Btw, if I ever want to switch to CM7.2 (I'm too lazy for that), is this guide the exact good way to do it ?
Upgrade the Samsung Galaxy Ace GT-S5830 to Android 2.3.7 Gingerbread via CyanogenMod 7
Click to expand...

The guide is good, just add one more step between step 10 & 11
Go to Mounts and Storage, format data, cache and system.

Steps 7 to 14 (including my addition) are standard for installing any rom in ace.
Just the gapps package is only required to be flashed with basic CM roms because they don't have any google apps in it, rest all custom roms(modified CM roms also) comes with google apps pre-installed, so flashing that is not required.
 
Thanks man, so no need to install the Gapps when flashing CM7.2 ?

Btw, last night I had the same issue with the Wifi. I woke up and the wifi icon wasn't there and my battery was drained again.

I'm getting really annoyed by this thing :(

the CM that you download from cyanogenmod's website does not have google apps, so you will need to flash them separately, but if you get a custom rom based on CM made by some developer then most probably the gapps would have already been added by him, if not he would tell you to flash them separately.

Why do you even leave the wifi on during night, wifi is such a battery eater, i never leave it on until unless i absolutely need it.
 
I leave it because I always left it on my BB. Its kind of annoying to be disabling the wifi everytime, when i leave home, when i go to sleep, etc. I just leave it while I'm at home, even if I sleep. If this continues I will have to turn it off while sleeping too :mad:


So I need the Gapps then! Do you know if the link on that article is the latest Gapps out there ?

Thanks!
 
Thanks man, really appreciate your help.

I'm starting to see with good eyes the installation of CM7.2 on my Ace since I'm kind of annoyed of all the bugs my phone currently has.

May I ask you the last 2 questions ?

1) After I do the procedure and start the new OS, do I have to reboot it again and root it and then flash again the CWM5 ? Or all of these persists after flashing the rom ?

2) I need to configure manually the APN settings of my vendor in order to have packet data, right ?

1. No, it will be rooted and with CWM5 you installed still running.
2. Depends on your carrier, if it works without it then good, else call up your carrier and ask for the APN settings.

If you are going ahead with this, make sure to have a CWM backup of your current rom in case you need to take the phone for service someday, you can use Odin to flash stock rom and restore your backup over it. You cannot restore stock rom backup on CM directly, they have different file systems.
 
Thanks again man!

I didn't understand your last statement. I already have a backup image that I did with CWM5.

In case anything fails with CM7.2, or in case I just don't like it, can I just reboot my device and restore my backup using the CWM recovery ?

You can't restore a stock rom's backup from a CM rom, the stock rom is in a rfs file system whereas the CM is an ext file system, the CWM can convert rfs to ext so that you can easily flash CM from stock, but it cannot convert ext to rfs, you either use some software to convert your file system to rfs and then restore that backup, or flash a stock rom using Odin and then restore your backup. Odin flashes converts the system to rfs.
I use Odin, i haven't tried manual conversion yet.
 
Oops, what a letdown is that!

So in case I don't like Cm7 and want to go back I need to get a stock rom for the Ace. Install the Odin, connect the phone in download mode and flash that stock rom. After that, I will be able to get my backed image back using CWM, right ?

Thanks again!!!!

yup, u got it!
 
Cool. Thanks again man :)

I really want to flash to Cm7.2. There's a new stable nightly from august 5th that I already downloaded (CyanogenMod Downloads).
But I'm kind of scared to find more bugs that I currently have on my stock. Or maybe I don't like. Which will make me do to the Odin thing (too lazy for that) in order to have my backup image back.

Do you have CM7.2 installed on your Ace ? Do you know if it uses to perform better than stock roms ? What do you recommend me ?
 
Odin takes a maximum of 5 minutes, 10 seconds to root it, 10 to install CWM and another 1minute to restore your backup. Maximum 7 minutes to get back, its just getting all the files that takes time.

I am using the Apocalypse rom since last 1 month, it is a custom rom based on the official CM nightly released on 8th july.
Its a brilliant rom, great performance, very smooth and a good battery life.
CM roms are popular because of their performance and customization options, stock roms are popular only for battery life. This rom's battery life is really good, specially with the new firekernel, quite close to stock.
And this rom has been tweaked for performance and smoothness.

In my opinion, CM is way better than stock. A little compromise on battery for all its extra features and no annoying bugs like on stock is a really good deal. I first flashed CM in november, i haven't gone back to stock yet, and i don't plan to either. :D

You can go with the new nightly also, i heard its giving really good performance, however i am not sure as the people using it haven't given much reviews yet.
You can take a look at Apocalypse if you like, here's the link.
[ROM] CM7-APOCALYPSE-FINAL [09.07.12] [FireKernel OC] - Page 157 - xda-developers
this the final version, previous ones were built on unofficial nightly, so if you want reviews on this, you might want to read the last 20-30 pages.

P.S This is for S5830 only, if you have any other model like S5830i/m/c/t/l you better tell not try any of this, specially the 'i' model.
 
Thanks for all the help man!

I have a S5830L. But don't worry about it. The L and B versions are just like the 5830.

The conflictive versions are the I, C and M :)


I think I will go ahead and flash it. I don't know which rom to put really. If the latest offical nightly build or that apocalypse rom you mentinoed. I always heard good reviews from it, so I'm sure it is the safest bet in my situation, but I don't quite like the ICS theme it has :/

What is that Torch option that the images always show ? It is always shown at the status bar like a lamp. Can I turn that off ?
 
Good to know you have been reading, it will always keep u safe.:)

what torch??

ics layouts are flashed separately in apocalypse , if u dnt like ics layouts and theme then dont flash it, they dont come preinstalled in the rom. Just flash the rom and u r done!
 
Thanks man. I have flashed to the latest offical CM7 nightly,.


Everything fine and really smooth so far!

The only pros, the internal memory is way down. I had 118MB free with the stock rom, and with this one (with all my apps restored with TB) I only have 82MB left. Is this normal ??

On a another note, the program monitor (task manager) is gone in this rom. So I cannot actually end any running process like Music.

What do you recommend me for this issue ?

Thanks again man!!

Also, I wanted to free some space up by deleting the data/log and noticed that this folder is not there (??)

And the *#9900# thingy to move dump files doesn't work either. I dial that and nothing happens :(

I'm on 79MB left now after upgrading 3 apps. Is this normal mate ?

That depends on your apps mate, move them to sd card, whichever the system lets you move, move it.

CM don't have taskmanager, its a ram heavy app serving no purpose at all. You can close apps from settings>applications>manage apps>running apps
Still if you want one, there is a ported version for CM available on xda. A lot of apps(system apps) working in your stock rom will not work in CM, they have a different framework, so this taskmanager app has been ported specially for CM users.

You can also get a task killer from the market, not the one which automatically kills apps in the background, but one through which you can close a background app upon your selection only, cause task killers are harmful for android, so they should only be used as app closing devices upon user requirement only.

yeah, i don't have it either, guess its not there in CM.:D
9900 doesn't works, they might have already included these in the system to save memory consumption. Well you will loose internal memory, this phone has a very low memory.
There are a few methods to clear some space like keep your internet cache clear, move apps 2 sd, clear dalvik cache from recovery(once a few weeks only) etc. But these are also temporary solutions only.

Since you are rooted, you can look into the permanent solutions too, moving apps to sd-ext partition. It involves creating a small partition on your sd card and then using it as an extension of the internal memory, so in all you get a bigger memory, use apps or scripts to move apps there. I am using Amarullz script, i have a 600mb internal memory now. Running over a 100 apps and still have 200mb free.
