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.
Rate this thread to express how you think the Samsung Galaxy S10+'s Wifi performs. A higher rating indicates that it has excellent range, throughput, and signal strength. Like when you're taking a dump in the bedroom upstairs, do your videos have to buffer or do they come through without interruption?
Then, drop a comment if you have anything to add!
I've noticed a huge upgrade in wifi strength , coming from a Note 9 . So am happy with that regard.
Hi,
Is anyone facing Upload Mode-CP Crash issue on Samsung Galaxy S10 Plus. Can't believe 2nd unit out of the box is having same issue. I have a dual SIM Exynos SM-G975F variant brought in Oman. 1st unit had this issue, even the 2nd replaced unit has the same issue. Phone freezes with a message Modem Crash!! & goes into Upload Mode. This happens at least 4 to 5 times a day.
Any suggestions.
Thanks,
I switched to S10+ from Mate 20 Pro. Connectivity it is way way better than S10+ and all my previous samsungs ( Note1-4, S2,4,7,8) . All wi fi, gps, 4g, signal in the mountains, etc etc in Huawei is not simply better. Is way way better
But I love more S10+ for everything else : soft, video, speakers, display, etc etc
I have both a note 2 and a note 5 here, as well as an Asus tablet, all of which are able to see and connect to hotspots located in businesses down the street from my home. They also show varying numbers of other neighborhood wifi networks. The S10+ however sees exactly 3 networks. Mine, and my next door neighbors 2.4 and 5 g ssids. That's it.
That said, the connection to my home network holds strong throughout my place, despite it dropping a bar or two in certain areas. Usually see upwards of 800Mbps indicated, and have no issue maxing my 350Mbps wan.
Not bad, but if I'm out and am in the presence of a weak signal, I might not even know it exists. This may actually work to my benefit though, because weak wifi signals really suck.

Maybe I am late to comment here. I have Note 9 for around 7 months and 2 weeks back switched to Galaxy S10+. A major drawback I am seeing with my device (running latest update) is Wifi signal strength which is not as good as Note 9. I used to get very strong reception in the areas around the house (I still have Note 9 and compared them both), but S10+ shows no signal for wifi in those areas. I have a dual band 5Gx and 2.4GHz networks and the strength is better for both bands on Note 9. Not saying it is a big issue, but the signal quality is not as good as Note 9. Does anyone switched from Snapdragon Note 9 experience the same difference?
The worst wifi and Lte signal i have ever encountred....coming from note 9 i thought am upgrading but now i miss my note 9
This phone has very bad WIFI range, + stupid Samsung software which kills low signal networks from even showing in list, you need use 3d party app to connect to them like WIFI analyzer..
Anyone having WiFi issues with the Note 10+, my phone is constantly disconnecting. I have a Unifi mesh network setup and it will disconnect on every roam it also does it when i don't roam to a different AP i can bet sitting in one spot with full signal and it will just disconnect. All my other wifi devices do not have this issue . Is there something im missing that could cause this
thanks
Do you happen to have bluetooth earbuds?
work good for me
unifi AP
It S my Config
I am noticing wifi issues as well. It seems to never stay connected, and also takes a long time to reconnect. It is frustrating and tiring
Which Note? I have no problem with mine (US Snapdragon), been watching TV for extended amount of time.

I have the Verizon note 10 plus 512 gb
I've used pixel phones for the past 4 years and both my Pixel 1XL and 3XL both do not kick over to Wifi calling until the signal was horrid (-120db +) on standby. I frequent lots of areas where the signal is sub par, but usable (-110 to -120db). The major issue with this logic is that you start a call on the network (in my case VZW) and shortly after the call connects to the person on the other end it kicks onto Wifi Calling. This is NOT a smooth transition. There is a 1-2 second 'blip' that causes the audio to cut out and I have to repeat myself... which is incredibility frustrating. I could turn off wifi calling, but then go into places like a basement and loose the call every time. The iPhone on the other hand if it has 1-3 bars and good wifi it switches to wifi and stays parked on wifi until you leave the wifi coverage area or the wireless coverage improves. What determines the signal level that the phones switch to wifi calling? Is it Android or the carrier? Does this differ my phone manufacturer? I'm looking to switch from Verizon to ATT, and ATT doesn't offer an updated LTE Microcell which means I would rely on wifi calling in my basement. I don't want to have the same wifi calling experience I have seen on VZW with a Pixel. Does Oneplus, LG, or Samsung do this better? Is there a root hack I could use to fix the problem?
I've only used it a couple of times as T-Mo isn't good where I'm at. I mean exactly where I'm at. I'm like in a dead zone in my apartment/complex. I get 1-2 bars max, but I can go about 20 yards, and get full bars. Wi-Fi was hit and miss as much as a bad cell signal for me. I tried to use it as "always on", but it didn't matter. I gave up, and ended up getting one of T-Mo's personal CellSpots, so now I get full bars in my place, and never have to use Wi-Fi calling. But to answer your question for me, yes, it sucks to use Wi-Fi calling.
WiFi calling is highly sensitive to your internet connection quality and jitter and also your router. I have had multiple configurations since WiFi calling has come into play. Your wireless router plays the biggest part from what I've noticed and their is so many different ones out there now. Best thing to do first is if you have a computer with a lan cable. Plug it directly into your modem and do a jitter test like this one https://www.fusionconnect.com/speed-test-plus/
Then make a note of what your results are. Now plug everything else back and set it up like your normally would have it and then do the same test over wireless through your router and compare the results to the first test. If they are quite a bit worst than the first results then your router is screwing it up. Most likely it's a premium feature (gimmick) that the router has that is screwing up stuff. I've only had TMobile with WiFi calling but my brother was on Verizon WiFi calling for a bit before switching over to TMobile and once I had a good configuration dialed in with a good internet connection and a good router set up he had no problems except for if he walked out of WiFi range sometimes. We don't have the best LTE signal at the house so the switchover wouldn't always be the smoothest.
Best combo I've tried so far is an Ubiquiti Edgerouter X and then using an Ubiquiti Unifi WiFi access point to give out WiFi. The Edgerouter X has a better type of QoS than most home routers nowadays and it can help WiFi calling issues a lot.
Now I have never experienced this issue you describe with it cutting out upon connection but it does sound like a typical switchover issue where it is switching from wifi calling to LTE or vice versa. Unfortunately that depends on the carrier and how they implement it on their network but I would definitely advise experimenting with your home internet set up if you ever have enough time as that could definitely be a factor as well
I have yet to see WI-FI calling work reliably - ( Engineer w/ 20+ yrs) Another technology pushed to production way too early.
