Wifi range has been terrible on this phone. I tried messing with my router settings for a while and thought maybe some phones are better than others but i lose my wifi calling too easily so I installed a wifi analyzer app and compared to my moms galaxy S 4g and my laptop. My network and the half dozen networks around me show the the same relative strengths but minus 20 db on the defy. Near or far g or n open or secured its pretty consistent -20 in comparison for each network i can see. I can get full bars of the wifi icon on defy but only with line of sight to the router.
Is this a known defect? If i return this phone is there a good chance that i'll get another one with bad wifi? I don't think there's too many defys left in the store.
Im running stock rom still so i don't think its a software problem.
I used my Galaxy S3 a few weeks ago
It is the Rogers i747m Galaxy S3 LTE
The major issues I am having are:
Weak Wi-Fi: the Wi-Fi is weaker than my iPad 3... It disconnects and connects... Even in my living room, next door from my router, my signal is either 1 bar or 0 bar for Wi-Fi, and sometimes it disconnects... My iPad in the same living room gets around 2/3 or 3/3 bars
Weak Cellular Reception: the weak cell signal is also an issue... It is not as weak as dropping my calls, but it is weak and slows down my data speeds...I am using in the wide open in Scarborough in Toronto, there are no high rise buildings.. On 2G, I get full bars... On 3G, I get a bar less than full. On 3.5G (HSPA+), I get 2 bars to half bars. And on 4G LTE, I get 2 bars or even worse no bars and it switches back to 3G or 3.5G HSPA+...
Never had these Wi-Fi and cellular signal issues with my Samsung Captivate and Samsung Wave S8500.....
Anyone can tell my if my phone is defective?
Or is this the phone hardware issue and it widespread with the North American LTE variant of the Galaxy S3?
Thanks.
Good Question, one of which I like to know myself. I'm in the west end (Brampton (for now lol) ), it seems like the signal strength varies even in the same city with only a 3 min drive apart and no tall building in sight lol. I'm talking 1248 kbps to 31743 kbps download.
Not sure about the cellular signal but the WiFi connecting and disconnecting is a known issue(by us, not sure if Samsung) and is being worked on. http://forum.xda-developers.com/showthread.php?t=1790187
Following the instructions in the OP fixes it for me but when I reboot the device, problem is back.
I haven't had any WiFi issues. I don't use it a lot. But I was testing it out tonight and it hasn't disconnected on me at all. I'll keep testing it out
and let you know if I lose WiFi connection. I do recall when I had the S2 i9100, I was losing WiFi connection quite a bit. I wonder if this is a random Samsung device issue? Or could it be an issue with the type of router you have?

If you have this issue, you'll notice right away as it'll connect and disconnect you every 5 seconds or so. I've only noticed it with one WAP and that's one at work, at home and elsewhere it works fine.
I am getting weak Wi-Fi signals around 0-2 bars.. And it disconnects sometimes at random but not as often as 5 seconds though...
Also, the question with the Wi-Fi issue being mass spread might be the International Tegra 3 version
The North American GS3 used the Qualcomm 89xx with has integrated Wi-Fi.. Possibly the North American model use a different antenna design...
I barely talk on my phone but the bars are about the same levels as my iphone 3gs before it was. My wifi I use it in 5ghz, and across my apartment, through 2 walls, im getting near wired speeds.
No issues with wifi here. I at least that I've noticed seems about the same compared to my iPhone and transformer tablet..
for me I am using it on wireless N on the 2.4 ghz band
I have yet to try on a 5 ghz band wireless N
My WiFi feels like it can go 1mb/second..
I do sometimes get roaming messages when I'm at home which confuses the heel out of me
Sent from my SGH-I747M using xda premium
I just accessed the *#0011# and turned the Wi-Fi Power Save to OFF and my S3 Power Save is also OFF
Wi-Fi signal is still VERY WEAK 1-2 bars and sometimes no bars... Did a Speedtest and got around 3Mbits/sec downlink and around 0.2Mbits/sec uplink...
On my laptop, I am getting 19Mbits/sec down and around 8Mbits/sec up.....
I checked the service menu's Wi-fi Information page on my S3 via dialing *#0011# -> MENU softkey -> WiFi
In the Wi-Fi Information, it shows my phone is connected to my router using 802.11b ONLY
What the heck??? ICS Software glitch???
You are getting 1MB/sec down ??!?
Damn how do you do it??
It seems like the North American GS3 with the Qualcomm LTE chip suffers the same Wi-Fi as the International version

But you must have a good Wi-Fi unit.. I will go to the store and exchange my White S3 i737m tomorrow and see if the Wi-Fi problem still persists..
Before you exchange your phone, could it be your router? Did you test your phone out with a different router or in someone else's house? I have no issues with mine. Like I said in my previous post, I had issues with WiFi on my S2. So I'm thinking it's a random Samsung issue with certain routers.
I have 3 different routers at home
1. Standard D-Link Dual-band N router which I bought last year
2. D-Link Xtreme N
3. Linksys Wireless N
| have tried on my Xtreme N and my Linksys on both 2.4ghz and 5.0ghz and the phone just has really low Wi-Fi signal either 0-2 bars of signal and it disconnects and reconnects at random...
The only way for me to get a good signal it basically using my phone 10cm from the router...
I tried the phone at a friend's house, in which case he has a Belkin Wireless N router. Also I tried it on University of Toronto St. George campus' WiFi... Both scenarios results in the same, low WiFi connection signal it seems to fluctuate randomly, Low down/uplink speeds and disconnection and reconnects at random...)
From the phone's service menu for WiFi, it show the phone is only connected to 802.11b (It will NEVER connect to g or n no matter what router I tried to connect to)
Non of these WiFi issues happen to my Samsung Captivate... When I use my Captivate, even when I am in the basement (my router is in the 2nd floor), my Captivate is getting around 50-75% WiFi signal strength on 802.11n
It seems like I did not have time today to exchange my phone due to some University essay due... Will probably exchange it on the weekend.
Will definitely report back on my exchanged model on XDA...

Its just damn good lol
Coming from Rogers Galaxy S II LTE, the LTE connection is weaker on the GSIII. Even when comparing it to the iPad3 at the same location at the same time, iPad connects fine on LTE and the GSIII at times is on 4G.
I did my exchange yesterday..
My WiFi disconnection seemed to have stopped. But the weak signal issue is still present..
I could not pick up public WiFi spots in my University... This is a ludicrous issue... Even in my house, I could barely pick up my own WiFi (if I am literally in the same room or a room next to the router).. My GS3 cannot even pickup any of my neighbors' WiFi. On my iPhone, Docomo Sharp SH-06D and my Samsung Captivate, I could pick up WiFi from neighbors across the street......
Well at least my new unit do not randomly disconnect and reconnect the WiFi now... But the weak signal link is still a MAJOR issue...
Hopefully Samsung will acknowledge the WiFi issue soon....
I have the exact same wifi issues as you. I've called Samsung and their support tech concurred with me that my phone is defective. I verified it with AT&T also when I took the phone to an AT&T corporate store and sat down with a salesperson there with an SGS 3. Connecting to the in store wifi the salesperson had full bars. I had barely one, and it kept reconnecting. I have to wait another couple of weeks before I can do a warranty exchange with At&t because I didn't buy my phone from a corporate store, I got it off of craigs list, and AT&T warranty services won't step in and help until the phone has been on sale for 31 days. So I'm having to wait until then. Meanwhile My data plan started on the 16th of July and I got a warning that I've used 65% of my 4g data up already. I'm sure I'm going to go over and they issued me a 10 dollar credit to take care of that.
It's inconvenient yeah, but at least I'll be taken care of.
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....

More than that, they would probably laugh in your face for even asking.
hello everybody , i bought 2 second hand lu6200 phones here in vietnam but their wifi coverage is awful , i can connect to wifi networks with an old phone and the
lu6200 just doesn't pick up the network, i installed an app to measure the db's and in the lu6200 it gets always atleast less 6 to 10 db's ,
first i thought that it was something wrong with the hardware but i switched phones in the store and have the same problem .-( ,
now i just don't know what to do , it's weird that a phone like this one has such a bad wifi coverage .... , i have tested a lot of roms also and
wifi always hard to connect with weak signals.... anyone knows something about this?????
thanks.

changed phones 3 times and they all had lousy wifi
I previously owned htc explorer and I used wifi and all three bars in the wifi were filled. I now own Lg g pro and sitting on the same spot wifi is hardly connected while on the laptop full signal strength is shown. On the pro wifi is hardly connected and only the dot in the wifi is highlighted and my wifi is randomly disconnected due to poor connection on g pro. is there any way to work this around and get stronger signal strength like my previous htc explorer. Does it depend on the rom. I am using rooted stock kitkat and have g pro at&t e980. I heard somewhere that "Its WiFi perception limits can be lowered at kernel level but this will cost some battery life." over here

how can we do this?
Hello everyone,
I wonder if anyone has experienced the following problems and if they have resolved them. My Lg G4 is having some serious problems with my 5ghz WiFi network at home. The 2.5 ghz works reasonably well but the speed of my 5 Ghz is more than twice the 2.5. So here is what happens, I am in the room of the router, excellent connection and all of a sudden during browsing facebook/random internet search about c++ programming/linux command the the internet cuts out. There is no internet on my phone what so ever, going to any page yields the same result. I pulled out my laptop and tested the connection on the 5 ghz and 90 megs per second.
If I turn the wifi off and turn it back on the phone reconnects and regains internetability (or the traffic starts going again).
I have tried resetting my phone, getting a replacement, changing router settings - I did everything from removing the key, leaving it unprotected to changing channels to doing firmware updates to no avail.
Has anyone had this issue and solved it?
Wireless on this device is seriously broken in every aspect. I've been battling the 5ghz issue for months now. They (VZW) know its an issue, LG knows it an issue. They credited me for two months but now say they wont do any more and I have to buy a new device out of my pocket. Even went as far as to tell me the G4 doesn't support 5ghz band and that they were sorry that I don't understand how WiFi works. They also refuse to warranty because its a software bug and any additional G4's will have the same issue. So its an issue, but its not an issue...according to them....Totally over it, and their lack of support.
Sorry, I don't have a solution for you, but I can confirm the G4 has 5ghz issues. The LG G2 also does, but much worse.
I have my G4 connected to 5ghz only (802.11ac) at home, and I experience this issue about once a week. (I'm sure it would be more if I used my phone at home more). The traffic all of the sudden just stops. Toggling wifi on/off or just waiting a long time solves it. My two other devices on 5ghz have zero issues. I can live with it because, so far, it has never interrupted important stuff like wifi calls.
Same result here on the 9th device stupid VZW has sent me and the 5ghz still dont work. I still cannot understand how it is that these people sell a broken device and can get away from the lemon laws. It is like a bank all we do is we take in the money and the broken product we sold to you is something you have to deal with.
