AT&T actually gave you credits for data even your phone was from Craigslist?!!

If it was Rogers, they wouldn't even cared.. lmao...

Samsung should make the WiFi issue public... This is NOT AN ISOLATED ISSUE.... It is much more widespread, not just on the ATT/Rogers/Bell/Telus Galaxy S3 i747(m) variants...

The WiFi problem persists on the International i9300 version as well....

....
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Firestar292:
More than that, they would probably laugh in your face for even asking.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] gunnyman:
I didn't even ask. The rep offered.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] godfirst:
You have to remember gunny we were having wifi issues in the beginning with the one x as well.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] gunnyman:
I never did. Matter of fact I'm back on the one x. Dropped the sgs 3.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] godfirst:
Wow, really. I still have both. I was having wifi issues with mine when I first got it, but with cleanRom and one of those ota my phone hasn't look back since.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mms6:
So the weak WiFi problem is a software issue?

This is actually rare for me to experience WiFi issues out of the box... (The other one being weak WiFi on my PS Vita, but not as weak as the GS3)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] godfirst:
My wifi signal is strong on the GS3, I just have the same issue I was experiencing with the HOX, which is wifi disconnect and reconnects.

I recently purchased my s3 10 days ago from best buy. Do you guys think I should return it and go for the one x? I'm really debating this. Only questioning the battery life on the one x...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] godfirst:
I have both, the battery life is excellent on the one x, especially if you root. I still prefer my sgs3 because of the raw power and multitasking, but the screen on the one x is beautiful.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mms6:
To be honest, the battery life on my Rogers GS3 i747m is not the best.. ESPECIALLY during standby.. It seems to suck a good amount of juice on standby on 3G, and especially LTE, it sucks even faster... Turning off 3 and LTE and stay on 2G GSM/Edge seems to be much better...

Battery life is still not up to par with my Rogers Samsung Wave S8500, or even with my Samsung Galaxy S Captivate.....

I haven't tried the One X... It has been a long time since I used a HTC phone (circa HTC TyTN) I can't comment on HTC smartphones...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ubiquitousrob:
Having weak signal issues here as well. My laptop i am typing this on has 4 bars and my s3 has 1 or none and keeps on dropping due to the low signal. I didnt notice this happening until the most recent ATT update.

Not sure if i just didnt notice it before and it was happening before the update or the update caused it but i really think it was the update because slow speeds caused me to notice the signal problems and i had no issues with slow speed before the update.

build number is IMM76d.i747UCALG1

Also just checked my wifi status and it is only connecting to 802.11b, no G...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ubiquitousrob:
checked my router and apparently it is a N router so the fact that it will only connect to B could be a lot of the issue. In order to get more than 1 bar of signal i need to be right next to the router...i also have a work router that uses G and i am seeing very low signal on that as well compared to my other devices.

I saw someone mention that turning off some QOS options on the router could fix the issue...going to log into my router and see if i can work it out.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] cosnomate:
same here

just got an sgs3 and I discovered the same problem, very weak wifi signal on the i747m. I don't use a sim card.

my testing/workaround is to connect my iphone to my wifi router (same router I tried to use with sgs3)... turn on hotspot on my iphone... put sgs3 next to my iphone... and connect it to the iphone's hotspot

definitely a samsung or ics bug :(

will follow up with samsung/bestbuy
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] drakeymcmb:
I dojt have this problem at all if anything it has better signal then anyone I had before
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Kapn.K:
Not seeing it.

i747(ATT). Great wifi and data. I was worried that the data would display H+, 3G, then H. I'm running ultimatum rom. I did a speed test and then my buddy did the same on his modded note which showed 4g. I got almost double on download. Wifi seems fine in my spread out house, as well. I think I'm not getting hung up on bars and stuff.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] sayce:
I'm also with Rogers with the S3 and I've had no problems with wifi so far. Good speeds no matter where I'm connected. Same with signal strength, nothing lower than usual and my data transfer speeds on LTE are still quicker than most people.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] insomniachou:
indeed, my galaxy has the same issue. At first I assume that it's a random defect in my single device so I replaced it in AT&T store. However the brand new one shares the same problem. While it connected to my router, it worked fine at first. But minutes later, it disconnected and connected again in seconds. I think it's a software issue, and hope it could be solved through updating.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bob129:
Not on AT&T or anything, i'm from Australia and on Telstra, but I have the exact same issue as you guys and have struggled to find any forum posts about it! (might just be most people don't go into the service menu to check what network they are actually connected to) but,

I'm on Telstra and having issues too. It's a work phone, and a colleague with the exact same phone, same firmware, etc is right next to me, and we both have different results when you go to the wifi data in the service log (*#0011#)

When I go to wifi, I have "N/A" listed next to CR: and Network, where as he has ¾ and 802.11a next to his. Also, my Link speed is 40mbps and his is 54mbps.

At home using my personal wifi, and with my gf's phone (S3 on Optus) I check the same things, for some reason my phone is on the b network (802.11b) and hers is on g (802.11g). My link speed is a measley 2mbps and hers is 54mbps, despite being connected to the exact same router, and both phones directly next to each other. Also, it seems her wifi actually stays connected when her phone goes to sleep, but mine d/c and has to reconnect each time I put the screen on.

Definitely some kind of software bug, or is it more of an issue with the actual wifi device inside the handset?

I've been browsing heaps of forums trying to find an answer and a remedy to this, but still no luck.

I've tried turning the Wifi Power Save Mode On/Off but it doesnt seem to affect any of the above issues.

It's also worth noting that at work I can't connect to the 2.4ghz band anymore...it just hangs saying "connecting..." and then "scanning" and back to "connecting", but I seem to be able to connect to the 5ghz ok.

At home I only have 2.4ghz, and it connects about 75% of the time..still hangs occasionally.

Any help/ideas would be appreciated.

Interesting thread. I have AT&T I747 and it has absolutely no problems with wi-fi. Very good signal strength in same room with router and as good as all other devices in other rooms. This is with Linksys b/g router and WAP2. Unless there are production quality issues with the phone, I'd have to wonder if there are aren't settings issues involved. I'd check for open channels with Wi-Fi Analyzer if data transfer is slow.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bob129:
Yeah I'm much the same. in the same room as the router it runs on G,even though the router is capable of N,and if I move more than a couple of metres from the router it switches to B and the link speed drops to a very slow 1-2Mbps.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bob129:
OK, this is weird, I've configured my router to only produce wireless N network, which works fine when I'm a metre or two from the router, but if I go to the other end of the house, the link speed drops from 36Mbps to 5Mbps or even as low as 2Mbps, and when I check the wifi connection thru the service utility (*#0011#) it tells me I'm connected to my N network with 802.11b....how is that possible?? Is it just a default somewhere that if the speed drops the phone just assumes it's on the slower network? And why does the speed drop? My gf's phone, which is also an S3, in the exact same room is on a link speed of 65Mbps, and hers confirms it's on the N network...

There definitely seems to be some kind of wireless reception issue of some kind...I just hope it's a bug in the software and not a hardware issue.

Any thoughts?

American wifi issue at&t

I to suffer from the same wifi issues stated above and have even contacted samsung support and they stated its a at&t thing when i told them that I have read it that multiple phones are having the same issue even not on at&t they kinda pushed my issue under the rug and told me that I have 30 days to exchange the item but seeing as I bought it from best buy mobile and those guys keep telling me to wait for an OTA update from at&t i missed my 30 day window. luckly i have phone insurance through best buy but I have to wait for them to get the replacement phones in before i can even get one and also unroot my device. but in short the guys at samsung played dumb and acted like they had never heard of the wifi issue I even told him over the phone how to enter service mode and turn wifi power save mode off, the guy didnt even know what pound codes were....., anyway I rommed the device and it still has the same issue to me that only kinda proves its something fautly with a select few phones and is very frustrating that when i choose a rom i have to make sure it has service mode on it or my wifi doesnt work. so if anyone knows of any roms with working service mode id like to know about them and if they are ics or jelly bean you can message me or reply in this thread or my other thread in the Q&A section. thanks guys id like to get a list going so people with this issue are more heard from and have ways of romming there phone while keeping service mode to fix the wifi issue maybe even get a member of cynagen to notice and open up service mode in cynagen mod 10(fav rom since it has jelly bean)

Having same 802.11b problem

I've been having the same 802.11b problem on my SGS1, and have been desperately looking for a solution for a LONG time.

Would really appreciate anyone having some ideas.. here's a thread I started some time ago with more specific details (with as yet no solution)

Hi guys,

I've had somewhat of a result with this issue. My phone was still within the 30 day replacement warranty, so iI took it back and they replaced it. the original faulted phone has gone off to Samsung for approximately 12 weeks for fault finding. not sure if I'll ever find out what they find as the issue, but there has atleast been some sort of admittance of a fault, by them replacing it.

the new phone has also helped prove there was an actual fault, as since I've been using the new phone there has been no Wi-Fi issues whatsoever, using the exact same networks, routers, etc. the only difference is the phone (hardware) and i haven't had any issues since.

Definitely take your phones back and demand a replacement. Hopefully after a few of these phones make it back to Samsung they will implement some sort of replacement warranty for Wi-Fi affected phones!

cheers

I'm getting the same poor wifi performance from this phone. I'm on Bell and it was a Telus phone originally that is unlocked. I'm assuming that this shouldn't matter.

My router is down the hall and it's an airport extreme. My ipad 3 is at full strength however my SG3 never goes beyond two bars.

Not good.

Samsung Galaxy S3 low wifi signal strength

Same problem for me. Really low wifi strength even when I'm right next to the router. Happens on all routers, home, work, public. Tried the *#0011# and didn't fix it. I notice there have been a few software updates recently but none have improved the problem. Looks like I'll be taking it back to the shop...

Cheers,

Greg
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] helousn:
I had the same problems; great wifi then poor wifi and then no wifi.. set back phone/rom back to basic.. whole 9 yards. Eventually took advantage of ATT warranty - replacement phone. No problems since. Talking to the employees - Was not the first S3 in for that issue.

I truly believe since I was the first buyer on the first day of ATT I just got a lemon.. obviously poor quality control to meet the first wave of orders with the wireless chip set and or antenna connection. Save yourself from more frustration and just get a replacement phone that works!

5GHz reception is better than 2.4GHz

My i9300 has extremely weak reception with 2.4GHz networks. I'm sitting in my office where I USED to pick up dozens of networks, but now all I see are the 5GHz networks.

When I first got the phone, Wi-Fi reception was fine. It was constantly connected at my home and at the office. Some time between then and now the phone's Wi-Fi reception dropped off the map. I literally have to be within 5-10 feet of a wireless access point in order to receive any 2.4GHz signal at all. As I mentioned before, 5GHz networks are showing up OK (with weak signals, but that's better than no signal at all).

This is all very frustrating. I'm on the Verizon network. I didn't take notice of the exact date the problem started, but it was somewhere around the time the 4.0.4 update was pushed to my phone (Sept. 19th, perhaps before, perhaps after). I just wanted some reassurance that this is in fact a software issue before I order replacement parts that *might* fix the issue. The two parts I'm thinking of are only around $10 total, but I'd rather not bother.

Samsung Galaxy S3 WEAK WIFI ISSUE

Hi,

I have a Samsung Galaxy S3 smartphone (which I have updated with the latest over the air update from Samsung when the phone alerted me to an update).

I have it connected to my home WiFi and the signal strength is very weak compared to other devices which I have tested in the same location.

The other devices that I compared the WiFi signal strength against include the following:

- My old HTC Desire smartphone

- My laptop

- Another laptop

- Apple iphone 4

All of the above devices have no problems at all connecting to my home WiFi and they all have full 5 out of 5 bars in most of my house which confirms that there is no problem with my router.

My new Samsung Galaxy S3 has a very weak signal and sometimes it goes to zero bars of signal strength. I have tried disabling the "WiFi Power Save Mode" from the Service Mode by dialing *#0011# however this did not help at all.

At first, I thought I had a faulty Galaxy S3 so I bought another one and had the exact same problem with the second Galaxy S3.

I emailed Samsung about this issue and this is their reply:

Dear Cameron,

Thank you for contacting Samsung and I have pleasure in providing the following assistance.

Please be advised that our engineers are currently investigating the issue you have described. If they find it to be a genuine fault then a firmware update to fix the issue will be rolled out as soon as possible. Due to the nature of our investigations we are unable to advise on a timescale for any possible update.

If you require any further assistance, please contact Samsung again and we will be more than happy to help.

Kind regards,

David

Online Support Team

SAMSUNG Customer Support Centre

So everyone needs to contact Samsung so that they can issue an update to fix this stupid problem that makes the phone useless.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] berserkdude:
I don't know if my problem is the same but my GS3 had a good signal till yesterday, and then for no aparent reason in the same area I got nothing more than 1 bar or less (6 meters away from the router)

I tried removing sim card + battery

Turning it on with no sim card

Factory reset

Firmware Upgrade and Initialization over Kies (it basically donwloads and istalls the rom I guess)

and with all these antempts, I don't know if a patch would do any good. Looks like a hardware problem to me...

Anyone tried flashing a new rom with odin?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] eduardo_b:
I'm doubtful that hardware would suddenly become an issue. A setting change or driver/software change could do it. Do you have a lot of auto-updates on the phone?

My S3 has very good signal but sometimes it wakes up and none of the bars are white. If I click off and then back on they are fine. Not how it should be, but I'm going to live with it rather than spending a lot of effort trying to hunt down the issue. A minor annoyance compared to your issue.

I will note that some routers have very poor signal strength, particularly if they have internal antennas. Simply changing to a router with two antennas has made a huge difference. At least for me. I've found that 6 meters can be a lot if you aren't in the same room with a router that has inconsistent signal strength.

Not sure any of this will help. But maybe.

I had gmail, facebook and samsung account to autosync and uptdate.

I have with me a HTC Desire, a Nokia N81, an Ipad 2nd generation and they are good. The GS3 was good too since yesterday.

I even tried changing a lot of setting in the router itself as well as testing my other router. and it is quite the same result.... poor wifi unless I'm 50cm away from the router.

SGS3 aokp jb, ktoonsez kt747 kernel

I never had any problems with mine even when I was on stock o.s and ROM +kernel but I will say it has gotten a lot better since I went to ktoonsez kernel and aokp job by task 650 but here me out before you switch to his kernel, read what he has to say about the updated WiFi drivers in his kernel bcuz once you flassh it you have to re-install stock drivers if you ever choose to use another kernel! But if your into molding your sg3 I strongly suggest looking into this ROM http://xdaforums.com/showthread.php?t=1766684

Scroll down the page to find ktoonsez kernel with the updated WiFi driver they will help! But you have to be rooted and on an aosp or aokp ROM and art variant!

Also I can tell you that for a lot of you it is a software issue bcuz people on good custom ROMs and o.s don't have this problem with the sgs3!

For example the ROM I'm on just updated to jelly bean 4.1.2 and its pretty awesome for those of you who didn't know it was out..for those who do sorry...root your phone people! Unlock its true potential and enjoy the wonderfull world of ROMs its not that hard like it used to be in fact its a lot easier on the sgs3 than any other phone made

i rooted the phone the same day i got it, but i missed to check wifi strength with the onboard stock rom. after i noticed its wifi issue, i tried everything possible (stock roms, ASOP, AOKP, leaked JB, reflashed stock roms, re-rooted, different kernels, different modems, etc.,) but i was unsuccessful.

the device is at samsung for 10 days now and i am eager to know if they fix it or change the whole device. if they exchange the device, i would say this indicates that samsung has a serious hardware problem.

WiFi randomly stopped

So I have been reading the forum and did a search, but I didn't see my specific problem. I've had my phone since the beginning of August. I've never had any issues with it, then yesterday my wifi just stopped working. :crying: I turn it on and it scans for networks, but won't find mine, or any of my neighbors' either. I did a hard reset of the router and I did a soft reset from my router's website. Our computers, TV, and my wife's Captivate Glide are all connecting to the wifi perfectly fine. I tried the *#0011# and turned off wifi power save, but to no avail. And now, my screen will not automatically turn off, either. I've tried forgetting and manually adding my network. Any help anyone can give would be greatly appreciated. Thanks in advance!

EDIT: I got to work this morning, and it works just fine at work. Any ideas?
