Hello everyone,
I'm stuck with a problem with the wifi reception/connection of my Samsung Galaxy S III (i9305) and I would really, really appreciate it if someone could help me fix it.
The problem is: The wifi doesn't work, unless I stand very close or next to the router (in a range of about 3-4 meters).
I have checked the Wifi Analyzer app, and it seems that the wifi is only functional when the signal is between -60 and -40 dBm. When the signal is between -60 dBm and -100 dBm nothing will load (websites, playstore, apps which require internet etc.).
These are the things I have tried:
- I have changed the wifi antenna of the phone with a fully functional one (the little thingy with the long cable)
- I have tried installing different ROMS (Stock ROM, Cyanogenmod and another one)
- I have turned the wifi power saving off (With the *#0011# code)
- I have reconnected to the router 9001 times (forget network and reconnecting)
- Factory resetted it 120382 times
None have solved the problem
I am 99.9999% Percent sure that the problem isn't with the router, since I have 2 other Galaxy S3 devices and they have no problems when going further than 4 meters from the router.
PLZ help me :crying::crying::crying:

I am happy htc hero user for 2 days. Tmobile (uk) branded. My problems started from the very begining. My phone was able to see my router and even connect with full signal strength but connection was inactive - couldnt do anything, browser giving error like no network connection available. I did my search and found kernel might have some issues with wpa psk coding. Tried all the settings on router (even with open network) - nothing helped. Updated to MoDaCo 3.1 rom and radio updated to newest available (downgraded using goldcard to root). Now i got wireless, can connect but its kinda slow (slower than 3g/hsdpa) and signal is very weak. I cant get signal at all downstairs where htc touch hd and nokia e71 both show ab 50% ?! even if i go to bathroom signal strength drops to 30% while htc touch hd and nokia e71 got ab 70%.
Router is netgear dg834g v5 - virgin.
Any suggestions please. I really like the device and this is only but major drawback.
It has been reported a lot that the Hero does not like some wireless routers. Various suggestions include that they won't connet to those using n rather than b or g. they will say they are connected but whenever you try to download you get an error message. I have 3 routers - 2 work fine and 1 (the newest and most expensive) doesn't.

I agree on this one. The signal is better one some routers. I have a great signal all the time when connected to my Linksys WRT54G (old but good one). At work, where we got Cisco SB Wireless-N Gigabit VPN Routers the signal drops quite often...
Can anybody confirm, that wifi (wlan) roaming, between different access points on the same SSID network and different channels, is working?
I have at home 2 access point (one is on channel 1 and another is on channel 6) and my SGS2 wouldn't switch from one AP to another when I walk in the house. My son has SGS1 and wifi roaming works for him. Before I had Nokia N95 and I had no problems with wifi roaming. The same thing, when I'm at work. We have 3 AP's (all three Cisco) in the house and switching between them doesn't work. In order to switch between AP's I toggle WiFi off then back on again.
I went from KE2 to KE7, now I'm on Litening ROM 1.5, but it's all the same.
I tried everything, I can think off (set AP/router to b/g/n, only b, only g, only n, set different channels, set different security,...tried also flashing different modems on the phone...) but for me wifi roaming is not working...
Any ideas?
Anybody?
Nobody? Realy?
That's realy strange...
Nobody?
I really can't believe.... almost 90 views and no answer...
I'm I the only one with this problem?
While you are moving round your house do you lose connection, i think that your phone will be connected to the strongest signal.
mine loses signal when i leave home and auto picks up an usecured signal down the road.
I don't quite understand, what you mean...
When I walk in my house from basement to the top floor, my SGS2 is always connected to the router in the basement. When I come to the 2nd floor, where I have another Access point, it should switch to that AP, but it wouldn't. Instead, it's still connected to the router in the basement, which (in the Wifi Analyzer) shows -90 db (and the AP on the 2nd floor shows -30). When I switch off Wifi on my SGS2 and then back on, then it will connect to the AP in the 2nd floor. But then, when I walk back, down to the basement, it stays connected to the AP on the 2nd floor, even when I stand next to the router in the basement and Wifi Analyzer shows -28 db on the router.
I can confirm that wifi roaming is not working (at least for me). The phone stays connected to the same old AP all the time even with really poor signal quality.
Unless it loses the connection it doesn't connect to the best AP available.
Tried it on several ROMs (multiple stock roms and now I am on Cognition 1.20), same behaviour every time.
Exactly the same with my SGS2.
I also tried several ROM's, from original KE7 to latest KG3, now I'm on Lite'ning 3.2, and it doesn't work...
That's really strange...
Exact same issue here. Tried three different stock ROMs and a couple of modified ROMs and no change.
I'm even running Cyanogenmod now and the problem persists! How does that work? Does Cyanogen use the Samsung source-code for the Wifi driver?
It's really pissing me off. I basically cant use Wifi on the end of the house I use it most in without cycling the Wifi on/off switch as I pass a different AP on my way into the house to get there!
The most strangest thing is, that nothing can be found on the web about this issue (only one on code.google.com)...
And also here, on XDA, millions of posts, but nothing about wifi roaming...
Are people not using more then one AP/router?

Yes, I am sure most people use one AP/router - that is why you are not seeing too many responses. The source code is from the samsung source drop, the drivers were written by broadcom. We at teamhacksung have not modified them for CM7, so the behavior would be the same across all ROMs that are using the drivers unmodified.
So, that means, we are stuck with this, until Samsung fix it?
I still can't believe, that the best phone on the world (at the moment... ) has such a flaw...
What about trying driver for Wifi from SGS1? On SGS1 wifi roaming works beautiful (my son has one and he is laughing at me all the time ).
Is there much difference between SGS1 and SGS2 in the wifi handling?
Wow - this is an annoying issue to have. Yup, i have 2 routers too, and it really sux to be in an 'overlapping' zone and see the SGS2 connect to the router that is further away.
Is there nothing that can be done about this?

I'm very pis..... angry, when I'm in my room/office, and see, that my phone is connected to the AP, which is in my son's room, two floors above me... and I'm sitting 1m away from router...
Yesterday I tried in my office with 3 AP's with my friend's SGS2 with original stock ROM KE2 (he didn't change nothing on the phone).
Result:....... the same as with my SGS2.... wifi roaming not working....
Any news about wifi roaming?
How annoying!
I'm having similar problems at work.
At home connectivity's fine with just 1 AP. Here at work there are about 10 Cisco APs. Every now and then I have to turn WiFi off and on again and I use the original stock rom.
I have exactly the same problem, it always connects to the same AP, not the one with the better signal... very annoying! How difficult is it to fix that?

Which channel does this AP have?
hello, as the topic suggest my galaxy s 2 's WiFi is PRETTY weak.. i hv goggled and found many suffer from this problem, but i couldn't find any solution. i was hoping someone over here could guide me to some script or update to fix this..
i noticed this problem when i step out of my room bars go down to 2.. and if i go little further with galaxy s 2 then no signal, my iphone 3gs and laptop catches signal fine at distance..i have tired routers at different location's, for example my friends house, in university, so problem definitely is in galaxys2.. it may it requires some other kernel or modded stock kernal.. i dont know..
btw i was on stock ROM same problem existed there, now i am Cyanogen Mod 7.1(2.3.7) and its here too..
please let me know what more could i add that might help you guys here figure out a solution.
thanks
Well, the wifi is not the strongest ever seen but i can use it outside my house (for about 10-15 meters away) without problems
Inside the house i have full/almost full signal in every room (on every rom tbh)
So yes, it's not strong but at my eyes, looks like yours is even weak than normal
mine also has a weaker signal than my other devices. However, I ran speedtest on all of them and the galaxy s2 has the same download and upload speed as the others. This is in spite of having zero or one out of three bars. I read in another forum that the wifi signal indicator of the galaxy s2 just shows a more accurate signal strength and the others just increase the indicators to make you believe that it has a strong signal. :-D
Maybe your router wifi transmitter is weak. Also you could try a different wifi channel on your router.
Same issues here
I just got GSII from sprint and i still have my other 2 EVOs and i loose wifi signal when i go downstairs or other rooms while my EVOs get nearly full bars and speed.I never remember having any wifi issues with my EVOs.I also have the same no or weak wifi issues at work while no other phones at work have such wifi signal problem.any suggestions...?
One thing I tried which helped a little was download 'WiFi Alanlytics' from the market and select your SSID and it will advice which is the 'Best' channel strength for your router.
Ant
poor signal
Hi i have same problem with poor signal.Any solution for this !? Try connect with 5 different router same stuff....flash with many different roms and no results any ideas ?

I agree completely, but another thing you should keep in mind is which modem is the best for you, i went though and tested 20 modems and ended up with LP6 which give me good range, speed, and battery, i suggest you test different modem types
Use THIS app to check, is highly accurate
another thing worth mentioning is that i recall once reading that all kernels will not be compatible with all modem types, I use Siyah kernel, GT i9100T, and BULP6 modem
hope that helps

*Modem/Radio/Baseband is all the same thing and can be seen by going to Settings - About Phone - Baseband. It's basically a driver which receives and sends Mobile Network signals as well as handling switching between GPRS, 3G, HSDPA etc....... (but not WiFi connection, that and switchover between Mobile Network and WiFi is handled by the kernel).
Whilst you are absolutely correct in saying modem has nothing to do wifi whatsoever, why revive a two month old thread ?
I know this question has been asked a lot of times, but I just want to know if this is a hardware problem that will always be here, or if this is a software bug.
My WiFi signal strength is full if I'm directly next to my router. For every step I take, I loose 1 stripe. So if I'm 5-6 meters awy from ym router, I don't have a signal at all. This is not my router, I've tested it with 2 other routers and a number of AP on campus - all the same problem.
I have the latest CM 11 spyder nightly build, I tried to disbale 5GHz (without any luck). My "Avoid poor connections" is obviously disabled. I deleted everything in data/misc/WiFi and also tried running wifical.sh without any improvements.
Does anyone know why this happens? Is there and fix/patch for this?
I am also having this same problem.
Find a fix yet?
Solved
Hi,
I found a way to fix it, days ago I changed the loud speaker of my xt916 , and after this my signal of wireless don't pass one bar, so I open him again and forced the two contacts beside the speaker to take a higher and lean better in the antenna's contact. After this my wirelles take the 3-4 bars as well.
Sorry about the English, i'm learning.
Hi,
I hope you can give me some advice on this strange problem.
I have a Asus MeMO Pad 8 (2014) (8 inch), ME181C tablet running KitKat 4.4.2
This tablet will only connect to a wifi router if the tablet is actually physically touching the router. When connected like this I have internet connectivity but if I move more that 48 inches from the router then I lose internet connectivity but the wifi remains connected, but is prone to disconnecting. Once disconnected it will not reconnect unless I touch the router with the tablet. I have access to 4 different routers and the situation is the same with all of then except that with one I can move 48 inches away but other a matter of 12 inches is enough to lose connectivity and ultimately the wifi connection drops.
The tablet can see all the surrounding networks and the signal strengths.
The wifi was working normally when I first got it a few months ago and the problem started after I did an over the air update. I have performed a factory reset twice to no effect. I rooted the tablet so that I could modify the system files and have followed many guides but to no avail. I had hoped that there was a setting somewhere that controlled how weak a wifi signal could be before it was ignored by the system as it seemed that the "avoided poor wifi AP" feature might be responsible but was not able to find anything..
Needless the say the wifi is almost useless and currently use Bluetooth access points, (ecodriod on a Raspberry Pi), to connect to the internet.
Grateful for any help advice on the issue, Thanks
I got same problem with my SS Galaxy S3 Korean LTE today. This morning I can use it ... then when I used it in the afternoon, I cant connect to internet anymore if I stay where closed to the router, with the signal very strong.
I think there was setting issue on your phone's wifi
Go to settings then wifi the go to wifi advanced settings there was an option (avoid poor connection) untick that
I think this will help you
