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

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...

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.
For some reason my area inexplicably became a dead zone about a month ago and now I have to rely on wifi calling. Only problem is this phone seems to have a weak wifi radio. My ipod touch and my laptop always have more bars. I get about 1 or 2 bars in my office and it drops calls at that point.
I read somewhere that different kernels can help with this issue. Does anyone have any suggestions?
Also interested
You HAVE to have cell service to make calls on wifi. If it can't at least register with the network it won't work.
What case are you using, my case weakens my WiFi signal

I go case free. And wifi calling works perfect when I am in the same room as the router. Go to another room and I constantly get call drop notifications.

i agree wifi is weak. at school i have a hard time connecting to their wifi. in settings it shows strength as very good but when i try to connect it takes along time and then doesnt connect after all because it says the signal is weak.
That's odd. I can't recall ever having an issue with wifi...
Is it supposedly a problem on all variants?
Sent from my SGH-T999 using xda app-developers app
Yes i've noticed that the WiFi reception is a bit weak with this device....I noticed it because I rely heavily on it in my house for WiFi calling, and I compared it with previous devices I've used with WiFi calling in the past.
I'm just sayin!

+1 for me noticing really weak WiFi.

Are you guys sure it isn't the router? Or perhaps it just reads/reports signal stregnth different than your older phones. (As in, the signal is just as strong, but your old phone reported that signal as 4bars, while the gs3 reports it as 3)
I'm not saying everyone is wrong, I know you're probably right on for your situation, I'm just trying to toss out things you may not have considered.
Right now I'm in my garage, about 15 yards away from my router with 2 walls (one brick) between, and I'm showing full signal. I can double that distance, add more walls and sitting in my car I still pull a signal. Yes it is far weaker but still useable.

Just a quick question. When wifi calling is on, the signal bar for your cell reception should be blank correct?

I just got a Sprint Samsung Galaxy S3 (had HTC Evo 3D before). I always used to use WiFi in my office with the Evo 3D since it was faster. Now I have a super fast LTE connection in the office -- isn't it better to use that (Sprint = unlimited data) and leave the WiFi off there?

LTE might not be as reliable as WiFi (it will depend on location and the building) plus LTE is a bigger battery drain then WiFi.

jamcar is right. I would have said battery drain first then reliability.

and kennyglass123 strikes again..
Because you're limited to lTE areas, and wifi would be consnistent and less battery drain. I don't have lte in my area yet, but i can pull 35mb down on my 5ghz band, so i'm not complaining.
Hmmm what about the fact that not everyone has unlimited data:banghead:

People keep saying LTE uses more battery than Wifi, but that is the opposite of my experience. Those of you posting that should post some proof of those claims.

This is the Sprint section, so all of us have unlimited data.
Well as the title pretty much says it, I am wondering if anyone is in the Phoenix, AZ area and what their speeds are on 3G. I'm asking because when I do manage to get 3G service, I have a whopping 5-15kbps average, with tops of 150kbps at like 3am when, I suppose, there is hardly anyone utilizing the network.
If anyone is in the area I'd love to hear your experience with Sprint and 3G. The way things are here, I'm pretty much just waiting for my contract to expire.
Happy I moved back to Chicago from phoenix omg to damn hot. I'm surprised your phone can take the heat. Well when I lived there sprint 3g was horrible I lived on north 28 drive down the street from a bus station and the mall.
In Chicago lte is blazing fast and I haven't seen 3g in months on my phone.

Trust me you are glad you moved out, apart form the heat Sprint's data connection sucks. Dial up is at least more reliable than the 3G service we have pretty much throughout the county. We've been promised 4G and LTE for about four years now...
I was between Phoenix and Surprise last week on a trip. Man, I thought our data speeds in central Wisconsin were bad. There were some times I couldn't get any data as it bounced from one bar of sprint to roaming. Awful. Feel bad for you. If I lived there, I probably would leave sprint.

If it wasn't for unlimited data and a hopeful spirit for improvement I'd have left quiet a while ago. I've been even connecting to 1x recently, I had almost forgotten it still existed.

So, not having run a speedtest on my laptop in a while, I actually thought my roommate was lying to me when he said we should be getting faster internet. Apparently he's not. Question being, with the speeds people are pulling on LTE, why can't I pull the same speeds from my wifi on my laptop as my GN2? My laptop is getting 50mbps down, while my Note tops out around 25mbps although yesterday I pulled a couple over 30mbps which has never happened before. Can anyone explain why I'm topping out like that when so much more is capable?
It can be a number of factors, buildings , wind , weather, static interference, anything could be a factor. It won't always be consistent.

Those factors have nothing to do with wifi or why my phone wont go over 25mbps when it can go way higher than that.
It could be the type of wifi antenna that we have on the phone. Max speed is achieved using MIMO streams which required multiple wifi antennas. I suspect that GN2 wifi have only one antenna, one stream up or down.

Just seems odd that it maxes out at that speed on wifi yet with LTe its capable of double that. Does anyone else get more than 25mbps on their wifi?
Mobile app might not use as much data. Not as much time to optimize the connection and really fly.
The pc site may be allowed more bandwidth to get a speedy connection with.
My two cents.
Hastily spouted for your befuddlement
LTE and wifi are not using the same antenna. MINO is the basic for wifi (N) to achieve higher speed. If you go out and by wireless adaptor. Usually there 2 type of Wifi (N) offer 150N and 300N. The 150N has only one attenna, and the 300N usually has at least 2 or more.
So... still curious, what are others getting on their home wifi?
What is your link speed. My usually at home SD shows 39 or 52 mbit but I have seen 72 too. I dont have internet service fast enough to see if phone is the bottleneck.

When I look at the network in the task manager on windows I believe its actually like 130? Im at work now, have to check when I get home? Is that the correct way to find out?
computer - 32
phone - 27
At home I have 40/20MB and on my phone I get 38/19 at work I have 100/100MB and on my phone I get 85/80MB.

So my link speed right now is actually 144 mbps, though during busy times it might go down to 130. It definitely seems like we are supposed to have better internet because I remember a couple months ago it was only 72. Anyways, what exactly am I doing wrong? Shouldn't I be getting even better than 50mbps on my laptop, at least? Also, my router came from Comcast, do I need to upgrade it to get the full effect or are my laptop and phone somehow limited? At home I'm getting better than 50 on my laptop so shouldn't I be getting 35 or 40 then, no problem, on my Note? It would be aggravating if Comcast was charging me for faster internet but not telling me I needed a new modem to take advantage of it. Actually, more like stupid than aggravating.

Yes you will always loose some throughput over wireless unless you have a beast of a router but plugged in with the hardwire should give you full speed. I would test by hard wiring to the router with your laptop and running a speed test then hard wire to the modem and do a speed test. If both router and modem are the same. Then its a wireless issue.

Well, I'm obviously not going to hardwire my laptop or Note. Would simply spending 50 bucks on a router from best buy, also avoiding a rental fee from comcast, improve my optimal speeds for my laptop and N2?

That's just to trouble shoot if it is your router or modem that is bad so you don't buy a new one when that was not the problem.

Well it's just the normal router that comcast gave us but I believe this was actually the second time we've updated so couldn't it be possible our comcast issued router is outdated? I've never been able to get better on any public wifi. I've just always had this creeping feeling that my account is just old enough to be on a weird plan where I am throttled overall no matter where I'm at opposed to other people. I've just never been able to duplicate the speeds on any phone that other people in my same exact area have. Like I'm handicapped for some reason., I mean, I basically get the same speeds on my N2 that I got on my Sensation, if not lower sometimes, and that just makes no damn sense whatsover. Don't we have a kikass radio over the Sensation?

I'm seeing similar to what you're seeing. I just had Verizon replace my router with a new Actiontec MI424WR which has gigabit & 802.11n. I have FiOS 50/25.
On a laptop running Windows 7 with an Intel 6300n wireless adapter one room away from the router I get 48-55 down. Sitting next to the laptop with the GN2 running ParanoidAndroid 3.15 with the LTE updated modem I get no more than 20 down. If I hold the phone 12 inches from the router in the other room, my Speedtest result hits as high as 33 down. If I take the laptop into the room and run the test next to the router, I consistently see 58 down.
Edit: Prior to getting my router replaced, I had the old Actiontec with 802.11g and if I recall, the laptop & GN2 both got around 12-15 down. Never better. Replacing the router made a huge difference but the laptop saw a high max down.
