Lightbulb WiFi issues disconnects etc (fixed for me)

I have had the phone 16 days now. First week was okay but this last week my WiFi has just been loosing connection like mad. All the time I had to toggle it to get it going after sleep. And even then it would loose connection multiple time pr minute.

I found this post on XDA: xda-developers - View Single Post - SG3 Know Faults Thread

Basically what user 'Muskstick' suggests is going into service mode (*#0011#), hit menu button, select wifi and disable the power save mode.

It's been working normally ever since :-)

Default cant find wifi settings in service mode

Hi, basically as the title says i cant find any setting related to power savings for the wifi. I typed in *#0011# but not a single option said wifi even if i chose in the menu to go back and go to the main menu. Can you tell me exactly wgat was it that you did in order to get it to work? I as well am having the intermittent wifi problems. Thanks in advance

I dialed *#0011# pressed menu button (first picture) then selected WIFI and got to the next screen (second picture). I pressed the button so it says "Off". Hit back until I was back in the homescreen. WIFI has worked to my satisfaction ever since.

I am on the initial firmware 'xxxxxLE8 if that makes a difference.

I switched off and restarted my phone and found the wifi problems had come back, when i checked i found this setting had reset itself back to 'on'.

So if you restart your phone for any reason you'll need to go back and switch this 'off'.

Default Day 7 - Still no issue with WiFi :-)

[QUOTE=flyer2308;4549988]I switched off and restarted my phone and found the wifi problems had come back, when i checked i found this setting had reset itself back to 'on'.

[old statement]Strange, I have booted my phone atleast 4 times since I turned off 'Power save' and I haven''t had a single issue with wifi.[old statement]
EDIT: Not true - my settings are gone after reboot also (don't know why it wasn't before).

I'm currently having the exact same problem. Also, whenever I connect to a new WiFi network, I have to do the same again. It's frustrating, especially considering I'm out and about and connecting to different hotspots regularly. I have now had 3 S3's, none of the previous two had this problem. (First was chipped when I opened the box, second kept vibrating constantly then crashing and either rebooting or turning itself off.)

Thumbs up Thank you!

Congratulations and thank you, solved my problem, really works, but every time you remove the battery from the device it is necessary to redo the procedure.

What a screwed up from Samsung!

Question [Bell Canada] wifi disconnect problem

I am new to Android, having just bought my wife a Samsung Galaxy SIII on Bell (Canada). It has Android 4.0 on it.

We have had it for a couple days now, and notice when we are at home it will sometimes drop the wifi network. Even when the wifi screen shows the network with a strong signal, it won't reconnect unless we turn off wifi and turn it back on.

I haven't been able to diagnose when/why it disconnects. I do not think it is any one particular app, or any period of time in use or not in use.

It is not an issue with the modem, router, or network in general as all our other connected devices do not seem to have an issue.

Anyone have any thoughts on this? Help would be appreciated as I learn this new problem. We have both Windows and Mac in our house, so Android is new and we are looking forward to using it!

so what is the point of the wifi power-saving mode if it doesn't save battery and all it does is make the wifi signal weaker?

I'm pretty sure it turns off wifi when you shut the screen off and uses mobile data to sync everything.

Some updated information. I turned off mobile data a day or two ago, leaving it wifi only.

On our home wifi, it will drop it every now and then. Never while in use, but after a period of time, when I go to use it, I notice wifi is gone. In the notification area, the wifi button at the top is highlighted bright green as if connected. If push that button, it goes dull green, indicating wifi turned off. However pushing it again, it will not turn back on. I have to go to Settings, and turn wifi on there. When I do, it turns on, and automatically connects to my home wifi network.

I have 30 days to return it in case it's a dud.

Anyone have any suggestions on this wifi dropping issue?

Here's one thread that found a fix for a few people...

WiFi issues disconnects etc (fixed for me)

I don't have an S3 yet but on DroidX the wifi will essentially disconnect when it hasn't been used for a while and then reconnect when I bring the phone out of sleep mode, which takes 30 seconds to a minute to reconnect. When my power control widget shows a muted green it is normally when something is in the process of turning on but is not fully powered up and connected yet (like wifi or blue tooth). Once the radio is on and connected the power widget indicator turns a brighter green. Maybe your wifi is going into power save mode and when you bring the phone out of sleep mode the wifi has not finished powering up and reconnecting to the router yet. Again, I don't have and S3 yet (still waiting for mine to arrive) so this could all be nonsense.

There was also another thread where someone said assigning a static IP to the phone helped.

Aerosigns tip worked for me, but I had to re-enter the fix every time the phone rebooted, I just got an OTA upgrade and was hopeful this bug would be fixed, but nope! Its still there! damned annoying!

Hi,

I'm new to this forum and new to the Galaxy S3 LTE version for about a week now but not new to smartphones. I'm in Canada and on the Rogers LTE network.

Having the exact same issues as Arkangil above so our phones are similar in behaviour. Basically my phone will connect successfully to my wifi network at home but will disconnect/reconnect frequently and sometimes fails to reconnect (with error failing authentication even though it hasn't changed) and have to force a reconnect by disabling WIFI and re-enablilng it.

I have determined that wifi works fine as long as the phone is plugged into a power source, however when running from battery is when I see the problem. I have disabled the general power save and enabled the feature to keep wifi always enabled.

I also already tried to use the procedure noted above in this thread to take phone into service mode and disable wifi power saving at the lower levels, however that procedure fails completely on my phone with the error message "UNKNOWN APPLICATION". Makes me wonder if it only works on a rooted phone or whether the LTE version of this phone differs much more than the international version of it.

I'm hesitant to take the phone back as everything else on the phone works well and generally really like this phone and features it provides.

Thanks.

Hi,
I have the international version S3 and the wifi was working fine for 2 weeks then it suddenly stopped. It stays connected to the router but no internet. I tried connecting other devices to the router and they all work fine.
I tried the *#0011# trick and it didnt work for me
So i accessed the router settings and found something called DYNAMIC ROUTING which was switched off. So I turned it on et voila...wifi works again
Hope this helps you

I posted something in another S3 wifi thread, but thought I'd post here too.

My husband and I just received our 32GB s3's this weekend. My wifi has no issues. His is doing the same things as described above. We did follow the steps for the *#0011# and that works temporarily but is not a permanent fix.

Because my s3 is working fine, we know it's NOT the router.

Has anyone come up with any other ideas? We'll be calling Verizon tonight.

I'm also having wifi problems, First off, when I turn off power saving mode it turns back on after I turn the phone off or restart it, is there a way to keep it off?

Now our household has two networks, both coming from the same router, one is what we connect all the household devices to so they can talk to each other, and the other is the one we give to guest. My father manages them and the settings but I assume the home one has some upped security.

When I'm connected to home I keep dropping and reconnecting maybe 10-15 times a day/night. Which is annoying. But when I'm on the guest one I can go weeks and not have a single problem. Just can't talk to my computer over wifi. So does anyone have suggestions? I assume it has to be a settings issue and nothing with the phone?

Thanks

Default Wifi connection problem!

Hello,
i now have a wifi problem,
Ive had the phone 3 days, the first two days the wifi was great, but today it is just not working.
All other laptops and pcs and phones work fine with wifi just this s3 is not.

The first two days when i turned wifi on - it connected automatically (after the initial connection asking for the password) and every thing was fine, but today when i turn wifi on no auto connection to the hub and no connection at all.
When i click wifi- the list of local wifi connection points come available, so i click on mine (which is repeated twice - one has "wps available" under it) and it says connecting for a few seconds and then it just returns to scanning, it will not connect and it will just keep scanning over and over and over again till wifi is turned off, Also under my wifi point name it says "Saved".

I press forgot network (on both of my repeated networks) and they just reappear.

Any help would be great

Thankyou!

Bump to get more input to the this thread.

I tried using the *#0011# method when my wifi was repeatedly disconnecting and it did keep me connected to the router, but it also drained my battery, going from ~40% to 15% over the course of 5 hours without any activity by me on the phone. It seemed that the orange download arrow under wifi was constantly lit, so I'm not sure how the power save mode made it constantly transmit data (I don't even know what it was downloading). This would be more of a concern to me than having to re-toggle the power save mode with every restart, although that would be annoying too.

Has anyone else who turned off power save mode noticed a significant (like my 25% drain over 5 hours without any activity) power drain?

The first two days when i turned wifi on - it connected automatically (after the initial connection asking for the password) and every thing was fine, but today when i turn wifi on no auto connection to the hub and no connection at all.
When i click wifi- the list of local wifi connection points come available, so i click on mine (which is repeated twice - one has "wps available" under it) and it says connecting for a few seconds and then it just returns to scanning, it will not connect and it will just keep scanning over and over and over again till wifi is turned off, Also under my wifi point name it says "Saved".

I press forgot network (on both of my repeated networks) and they just reappear.

Any help would be great

Thankyou!
Merged your post over here so that you may consider the tip in this thread.

A few other good things to know (wish my neighbors did, LoL!) -

- don't use the default network name that came with your router, be creative (and keep it short, no spaces)

- do try Wifi Analyzer, free in the Store, to see if your wifi network is on the same channel as everyone elses - because that may work, but it's not the right way

Both of the above can be set in your router.

And in the event of phone once working and then not for no reason - try a router reset. Many ills have been cured with that one simple trick.

Welcome to the forums!

Default Wifi constantly con/disconnecting

I've had my S3 for 4 days now. I didn't have this issue the first 2 days, but the last 2 I have. My home wifi is constantly dropping the signal, disconnecting, scanning and then reconnecting...over and over, as little as every 30 seconds it seems. I have other devices (the computer im using right now) that do not lose the wifi signal and do not have this issue. Any suggestions?

I really don't know whats going on and I could be way off here but im wondering if its not some kind of compatibility with the settings on the router, I would guess the wifi radio in phone is different than the laptop and that's why the laptop isn't having the issue(?)...The only reason I think that is im coming from a Droid X and I had a similar issue with that phone on my home wifi (no issues on other wifi's, like work - just at home). I think my DX couldn't even find the signal at times though, even if I was right next to the router. Anyways, I don't know enough about router settings, and maybe im way off in that thought...any suggestions on where to start?

Appreciate it!

This is a common know issue with android devices. Try wifi fixer from the Google play store. That worked for me.

Came across this thread when doing some digging so I'll add my 10p.

UK (Orange) International S3 here - can connect and use WiFi OK but there are 2 slightly irritating issues.

1 - the phone will sometimes drop WiFi and takes a while to reconnect when you switch it on (resulting in the lockscreen being unresponsive and then going black instead of letting you in to use the phone)

2 - the phone sometimes takes a LONG time to scan for WiFi networks - not a problem once the ones you use most are 'remembered' but not ideal.

In both cases I'm pretty sure the issue is the WiFi going into powersave mode - which is annoying as the option to keep the WiFi alive, even when the phone is on standby, is selected.

I'm going to try a Wifi Fixer/Keep-Alive tool to see if that helps any - but clearly a better fix is required ASAP from Samsung.

When my phone sleeps for a duration of time, upon wakeup my Wi-Fi shows it is still connected but zero data can be transfered. E-mail/playstore/browers can not connect. I have to turn wifi off and on again for it to re-establish. This causes my email pushes not to come through. I've played with some router settings, but have not forced the phone onto 2.4 or 5ghz. WMM is enabled as well. I have now just enabled the wifi sleep trick in the service menu, and I had the keep wifi on during sleep already on in the regular menu. Now my screen won't time out after the service menu trick. I called for a handset replacement and got the speech about clearing cookies and wipe phone data. Sigh... So I have to remember to turn this on every reboot and make sure to turn my screen off each time. Regret is sinking in, as I told my self never again after a Behold II. T-mobile please get a good HTC phone, I think the S3 is going back!

Default Possible fix

Possible Fix

My unit is presenting the connected wifi after sleep, with no data actually working. I have a dual radio 2.4ghz and 5ghz router. I split the SSID's for the bands so each is unique. The problem has yet to occur again. Note I only have entered one of the SSIDs at a time, but neither have presented an issue. Just another idea for you all to try.

This is exactly the issue I am experiencing with my VZW GS3 connected to my home Apple Airport Extreme. None of my previous phones (iOS and Android) had this problem, but the S3 is having it intermittently. After not using my phone for a while, I'll turn the screen on and have no data connection. However, it still shows it is connected to my WIFI, but no data will go through. If I go into WIFI settings and try to re-connect, it will not do it. Simply turning off WIFI and turning it back on corrects the problem immediately (it will re-connect to my WIFI automatically after doing this). I mostly notice this after checking my phone first thing in the morning after waking up. If I don't have my phone plugged into the wall charger, my phone will lose a lot more battery because it is on the 4G network instead of WIFI (even though it shows I'm still on WIFI).

So far, it hasn't been a major issue for me, but definitely one that needs to be addressed.

Are there any special steps that are required to enable service mode?

I have just been typing #0011# and then hitting the green call button. It tries, says "unable to process request" and boots me back to the main screen. Am I missing something?

T-Mobile Samsung Galaxy S3

[edit] Figured it out. Apparently that wasn't "#0011#" and was *#0011#, as in "type * first"[/edit]

Thx JayC -- this is the impression I've had as well. I had the same wi-fi issue with my DX, but my BB from several years ago and a Palm Pixi+ did not (well, not nearly as often anyway). I was a little surprised/disappointed that the S3 would also have this problem, but if it's something with Android itself it might explain it. Just surprised it hasn't been rectified by now. Otherwise the phone works pretty well in other respects where I had issues with the DX.

Also, sometimes when my wi-fi stops working the 4G doesn't kick in, either. I usually have to reboot the phone. This is bad for me because I receive emergency email alerts from my work 24/7, which is why I notice it. I'll try the wifi fixer and see if that helps. (I do not have Power Save mode turned on).

Try the SSID split I posted, let me know your results. So far it has been good here.

*#0011# thingy must be done after every reboot. That's what I figured after a reboot of my phone.
