Well, I'm thinking that may have worked. After changing to split SSID's, the WIFI has not disconnected (I'm connecting to the 5ghz one). Thanks for the tip!

I'm about ready to say the *#0011# trick worked for me, now I'm just concerned that it's draining the battery faster.

Could be my imagination... but could also not.

Its a long story but on my Galaxy S2 I had two Wi-Fi apps - WiFi Tracker and WeFi, and when I got my S3 I installed them there as well. I had slight problems connecting to my home Wi-Fi till I tried uninstalling them and.......my S3 connects perfectly all the time! I guess sometimes "less is more"?

Lolz thought it would just be me! I guess maybe having 3 apps competing to do the same thing confuses the phone?

Hello, I had the same issue where my GS3 kept disconnecting and reconnecting to my wifi. I did the *#0011# thing and it worked. I had to turn off my phone last night as my battery was dying and I didn't have my charger with me. When I came home and charged my phone, I noticed that it was happening again so I again did the *#0011# thing and it fixed it, however now my screen won't auto turn off/lock. I have to manually lock my screen. My settings are set to auto timeout after 30 seconds but its still not doing that. Has anyone else had this issue?

I just did it - screen will not time out. I set it for 15 seconds - it just stays on - I had to manually turn it off.

Default Wifi problem solved

I've also had issues with my Galaxy S III. It kept coming up with 'authentication error' when I tried to connect to my home wifi.

It was encrypted with a 64 bit key WEP, and it would connect fine with the encryption turned off. I have changed it to a 256bit TKIP WPA-PSK key and it works fine.

The rest of the above didn't work.

I had the same problem with 3 Galaxy S3 32GB phones. Took them in to 2 Sprint locations and their techs were unable to connect them to their own in-store wifi routers.

Tried every trick posted to date:
- Advanced Wifi: Shut off notifications
- More Settings > Disabled Kies services
- Service Mode *#0011# > Wifi > Shut off Wifi Power Save Mode
- Tried every DCHP and Static IP connection possible (would occasionally connect with static IP but never hold it).

The only clue was that at SOME open public locations, the wifi connectivity was fine.

The fix was replace an 8-year old router. The Galaxy S3 hates WEP or the old WPA1 standard...and for good reason, as these are completely insecure protocols.

While there are many fancy new routers available, I selected a refurb'ed Netgear WNDR3400 for $40 online. Im using WPA2-PSK AES wireless security, can connect 2 Galaxy S3 phones (1 stock/unmodified, 1 optimized/debloated) and can connect both either DCHP or Static IP. In this configuration, the S3 does not need the wifi powersave mode disabled to remain connected.

Mine seems to have issues with a Cisco AP running LEAP 802.1x authentication. Granted I have to run a special configurator to get LEAP configured, but I still have random disconnects.

I wonder why they don't give you LEAP as an option when you set up WiFi. The OS obviously supports it.

Default Still not working

Hi All,
My Galaxy S III still will not hold wifi in any location in Vancouver CA. I know it is either the hardware or software since iPhones, laptops, etc. are working in all of the wifi zones I've tried. We have tried all of the fixes people have suggested here to no avail.

In my case, the phone is an AT&T and holds wifi when in the states but will not hold wifi when in Vancouver. Samsung chat tech says a fix is on the way but that's been two weeks now. Anyone having the same problem or have any advice.

Love the phone otherwise but will probably exchange it for iPhone if no resolution quickly.

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 :-)

The day after I made this post I brought my phone back to Verizon and they replaced my phone. I have had no issues and its been several weeks. I made no changes to my wifi settings or hardware. Also since I havent done the *#0011# thing, my battery life is much better.

Default Did firmware XLH1 fix it?

I got the XLH1 OTA update and this trick hasn't been needed since :-)

Has anyone else had the same experience?

And I haven't needed the *#0011# trick since that update. Everything work as expected. Normally I notice the problems a few minutes after reboot but they seems to be fixed now :-)

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.
Mine usually stops once a week or so so I may try this power saver trick.
The quck fix I've been using is rebooting my router. It is only temporary.
Type my ip into your browser, copy it and paste ip # in add bar.Takes you to your router page. Go to setup wizard and click next until it reboots.
Kind of a pain but takes less than a minute. Works for my LG and girlfriends Samsung.

One downside I noticed (at least with my phone anyway) is that the fix also disables the display timeout so my screen stays on all the time(?)

I have the latest verizon update and the problem persists.
I've simply decided to leave my wifi on during sleep, this fixed the intermittent issue. No real drop in battery power either.
If battery is a real issue, get the mugen power 4600mah battery!

Hi guys.
I had to sign up after discovering this topic by googling,
and I have the same issue.
Obviously it's not any country/operator specific problem only in North America,
I'm from Europe, Finland ..
I just bought Galaxy S3, 3 days ago.. and eversince I've had this same problem
when I run my galaxy as an wifi hotspot for my laptop..
It disconnects every now and then, very irritating.
None of the tricks described earlier works for me.
I'm starting to think it's Android OS problem, not Galaxy..
Got android 4.0.4 on the mobile,which it updated the other day.

Tmo S3, turned the wifi powersaving off and it also will not turn off my display automatically with time out settings. Restarted the phone and it appears the power saving has been turned off and the display dims after the set amount of time.

I've always lost this setting after any reboot. I've been plagued by this lost WiFi connection problem only over the last few weeks.

I've just now rebooted after confirming the ServiceMode setting was fixed to Off and confirmed similar setting from within the Advanced Wi-Fi menu (set to "Always").

After the reboot, the Advanced Wi-Fi menu reports "Always" but the ServiceMode has reverted to ON.

So there is a conflict between the reports and I have to say that the Advanced Wi-Fi menu is incorrect and the setting is indeed not permanent as desired.

Sorry about this, I should have corrected it a long time ago. I loose my setting after reboot also. I am not why it didn't happen in the beginning.

Anyway as stated in a later post in this thread - my isssues dissapered with one of the later patches. I don't mess woth this setting anymore...

Just change the encryption of the wireless security`s router to automatic (TKIP + AES) in WPA2-PSK version and it will connect with no error.

I don't even have encryption at all!.... only mac address filtering.....

If I leave mine set to Advanced Wi-Fi menu reports "Always", I have no problems.. don't really notice any hit on battery either.

However I do tell mine not to alert me everytime there is a wifi signal around.

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 :-)

You have to do this after every reboot as well. It defaults back to on after a reboot.

Default WiFi issue - S3 does not allow any data

Hi,

I have a 2 weeks old S3, international edition.

After a week it stops transferring data on the WiFi network, the only way that worked was reboot to factory settings.
Now it happens again, WiFi claims "connected" but no data flow.

Any ideas?

Thanks
Jacob

Have you ever tried to connect to a wifi access point which is now out of range? I did that a few weeks ago and found that the unavailable point was at the top of the list and it was ignoring my home modem.

Default Galaxy S3 WIFI Drops FIXED!

Thank you very much for your post. I google'd the same issue and came across your fix. I went into the service mode and disabled the "WIFI Power Save Mode". Thanks go out to 'Muskstick' as well for the original post!

Do you still have to do it every time you reboot?
I haven't tried it since I've gone from android version 4.04 to 4.11.

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]
This is not working for me. It just acts like a dead phone number. Says it cannot be completed as dialed. Im not sure what i am doing wrong.
