I've had two Galaxy S II phones now, and I've had the same problem with both devices. The phone's wifi is great -- when it works. Although I noticed that the death grip lowers the wifi signal bar, I can still browse the internet and download apps just fine.
The problem is that, at times, the phone will show wifi connectivity and yet, I can't browse the internet or access the App Store. I'll have to shut off the wifi multiple times and even this doesn't work 100% of the time. Shutting off the phone and turning it back on works 100% of the time.
Since this has happened to two phones, I'm beginning to question whether I have an issue with the wireless router because I have not come across this as a prevalent issue. At the same time, my laptop and a family member's iphone doesn't have the same issue.
Anyone else having this problem? Or have suggestion for fixing the problem?
Thanks
Here is me showing the problem on video:
My roommate and I both have the Galaxy SII and he constantly has problems connecting to our wifi. The only difference in our phones is his is rooted and mine is not. I plan on rooting my one of these days but would like to fix the other issues I am having first.
Mine isn't rooted, but it still has the connectivity problem.
EDIT:
I may have found the the solution. Probably unique to my situation, but what I did was disable WPS on my router. It's a medialink router and I thought I had disabled it (per instruction) but it was on. Perhaps that was the issue. So far, no problem.
EDIT:
Nope, the wifi has dropped again. By dropped, I don't mean it drops in the middle of browsing. It seems to drop after I've stopped using the phone for a while. I've already checked to see that the phone is to never turn off the wifi when the display is off/sleep.
Arghhh
same exact problem.
wifi on moto surfboard sbg6580
did the static ip fix continue to work?
Any phone is the same.

Don't have any issue with wi-fi , mine is rooted on stock rom
i have no issues with wifi on my sgs2, i have wifi on 24/7, and on wifi proabably 50% of the time. it connects and disconnects when supposed to, picks up on cell data and drops when its supposed to..
fwiw, my GF has an iphone 4, she had problems connecting to the HOME wifi, but no where else, i updated the firmware on the router, same problem, i swapped out the router for a spare a friend had, and setup a second access point on the same network, just called it the same SSID but put a "2" after it.
her connectivity problems went away, immediatly she noticed a difference and has never complained of a drop since...
try different encryption methods, if you're using wep, try wpa, try a few different things.
also try a firmware update, you might lose your settings during a firmware update, but there is usually a backup/restore option you can use. backup your settings before flash, then restore after. if you have access, for at least testing purposes, hook up another router and use it to connect to and see if the same problems persist.
No problems at all connecting to a WHR-G54S running Tomato.
The Moto Surfboards are known to be flaky.
I had the same problem. after getting another one I found out that if I didn't download so many apps at one time the problem mostly stopped and after running a couple weeks, I haven't had the problem with connection since. I'm not sure it will help, but I did a factory data reset and reinstalled the apps one our two at a time (it's frustrating, I know).

Anyone know why WiFi would work some places and not others? For example it won't work at my house. Just keeps saying scanning, connecting, disconnecting. I have gotten it to work in one bldg I work in. Not any other place. Is there a way to clear it out and start fresh? I have been able to.connect in the past with this phone and my wireless router at home. This all started 3 days ago. Im running complete stock. I have rebooted computer, router and phone, to no avail.

No clue. Mine unfortunately seems to work everywhere but my house. I have to keep wifi switched off when I get home because it causes the internet to stop working for every device in the house. Pretty inconvenient. Anyway I decided to buy a new router to see if that fixes it. Should be here tomorrow.
Well the new router fixed my wifi problem. I bought this Medialink - Wireless N Router ( amazon.com/gp/product/B0044YU60M/ref=ox_sc_act_title_2?ie=UTF8&m=A1DCPNQKKEISZB ) Sorry, forum wont let me post links yet. Set it up in a few minutes and instantly had wifi on my rezound.
Hi,
got my SGS3 today and started playing with it. I started downloading my apps and during this the wifi dropped connection 3 times. It connected again within seconds, but this is not good.
The distance from my router was around 3 meter. My SGS1 never dropped connection.......
Any idea's?
I also have problems with wifi:
It connects normally but after tens of seconds the connection is dead. Android says still it's connected, but it simply doesn't work.. I have no sim installed atm because I have only an oldskool sim and not a micro sim. Tomorrow I will get a microsim at the vf shop and test again..
I had issues like those aswell today using my Adam but only with wireless. Weird ?
Probably your router problem? I'm sure reviewers would have identified that issue as well. Can't wait to get mine though, hopefully mine don't have the same problem
Htc hero, sgs 2 and three notebooks are working fine. Tried different router configs.. Nothing helped. Today i receive a 2nd sgs 3, so I will put it on the test..

I have a similar issue, the status bar shows wifi is fine (the arrows are blinking) but no actual data on the phone. Checked on my tf201 on the same network and its working fine.
This has happened twice now and only restarting the phone fixes the issue.
I have downloaded over 2 Gb with my SG S3 over Wifi at home and at work. No issues, and it´s super fast, even beating my XOOM.
I have a Dlink 625 at home and at work we have a Cisco something.
However had a different problem where the phone just restarts when dialing a number, and then it boot looped on the logo for about 5 times before starting up. scary .

This is the same problem I was talking about, but rebooting does not work for me..
Mine seemed to behave a little like this to start with also - I changed the Wifi Frequency Band (Settings-WiFi-Advanced) to 2.4ghz only and its been rock solid since.

Yes, it is in b+g+n mixed mode and is saying 2.4ghz. As a matter of fact I'm not able to chose another frequency (maybe because of the b and g). I can try to put it in b/g or g only mode.
I also read about that NFC's RF signals can interrupt the Wifi signal, so I will try also to disable the NFC option.
I tried another galaxy s 3 with the same settings.. that one works well on my wifi network.. I think the wifi module is not working properly..
Do you have by coincidence a draytek router. I have the SGS3, and my sister has the SGS2. We both experience problems with wifi also here. I have several draytek routers, all giving problems.
It seems to become a bit more stable if you set the Channel width to just 20 MHz, in stead of 20/40MHz. And use WPA2 only, not a mix of WPA and WPA2.
These two changes made the connection a bit more stable for me, but i'm not 100% convinced yet.
mine doesnt hv any issue with wifi, but for my cell signal, it changes between 3g <> h <> h+ alll the time, anyone too?

I posted a solution for this in the known issues thread but I thought I'd repost here in case you missed it.
I was having similar problems but found that if I disabled the Wifi Power Save Mode I was back to blazingly fast speeds and no dropped connections.
I had to go into Service Mode (dialling *#0011#) and hitting Menu => Wifi and turning off the option for power save mode.
Give it a try. It fixed a couple of other guys problems as well.
Am giving this a go will report back.
That worked but battery drainer . Have put it back on and set wifi to off when screen off. That has helped loads.
Worked for me too, and trip really is unnecessarily complicated and hidden to get something that should be working out the box.
I have searched all over and I don't find an answer, if I'm missing a thread please just point me in the right direction.
My home wifi has been working with my Note just fine since I got the phone (cue ominous music) up until yesterday. Last night, it started asking me for a password (which was weird, because it hadn't since I first got the phone and set the connection up), and I put the password in, but it kept saying "authorization error." I am really frustrated, I rebooted the phone, the router, removed the home wifi connection (the "forget" button) and reinput it -- I even booted into "safe" mode to make sure it wasn't some app -- no joy. It's a very simple linksys router, WPA/WPA2 security, all the other tablets/computers/phones in the house work just fine (tablets/other phone Android, laptops Windows.) And my Note was working just fine until last night -- no recent software install or update, it was seemingly just random. It's a stock Verizon Note, I haven't even bothered to root since it does everything I want.
Here's the kicker: I connect to OTHER public networks just fine. I connected to my work and McDonald's wifi this morning, no problems.
What could be wrong? I really need to be able to use my wifi at home, I don't see anything in Google or on the boards about this. I am hoping my search-fu is weak and someone knows what is up with this.
restore defaults on your router, then setup a new password.
Hope this Helps....

I have been experiencing this problem for the past 4 days. I have owned my Note II since December 25, 2012 and it has been working on any WIFI AP ive tried. 4 days ago in the middle of the day, my phone started giving out "authorization error" and would not let me log in to my home WIFI. I have 4 computers, 3 smartphones and other devices all working perfectly in my home WIFI. My problem even occurred when connecting to open, unsecured WIFI AP also. Nothing seemed to work. I called Verizon and did all the steps leading up to factory reset. With no luck on any tricks or tips from them I called Samsung. They walked me through the same processes and everything, so I decided to do a factory reset. This did not fix anything. I still get "authorization error" and "wrong password" on any WIFI i try to connect to.
I found out yesterday if I stand within 5 feet of my WIFI router I can connect and browse the internet for a few minutes until it kicks me off and does the same old "authorization error". If I sign in to my WIFI within the 5 feet and walk away, it disconnects and again, gives me the error messages.
I called Verizon back and they are sending me a replacement phone.
TL;DR:
Try accessing your WIFI when you are right next to it.
If problems still persist, call your carrier.
I hope your phone isnt as busted as mine.
Argh, that's bad. At least my phone connected to open networks so I knew the hardware was ok -- I wiped the router and set it up again (per the suggestion in this thread) and I'm good for now. (Embarrassed I didn't think of that myself) Hope you have better luck with your replacement phone!

Ok............ wow you have me 100% nervous now. I've been experiencing this issue ever since I unlocked, rooted and ROM'd my Note 2 back in the middle of December, and I experience the problem with only my Wireless-N SSID on my router. I can connect to the Wireless-G band just fine but the N one gives me this error no matter whether it's open or not. I seriously hope this isn't an issue of broken hardware..............
I figured this was worth mentioning. I have 3 Note 2's in my household, 2 of them are running Beans Build 5 and Perseus kernel overclocked and the other phone is totally stock.
All 3 phones have the exact same issue of connecting to the 802.11 N band on my router. They connect to the G band just fine. I think this rules out any worries about it being a lemon issue. Most definitely is a Samsung software issue that's been happening to multiple models going back a few years. Here's a google search of this issue using non-phone specific parameters. Notice how ALL phone specific forums point to a Samsung device.
I have a bad feeling that this is not something that will be getting resolved any time soon.
Edit:
The plot thickens. I have performed some tests on my router to see if I could get my phone to connect. Well here's my results:
5Ghz band = Wireless-N Only = Authentication error occurred
5Ghz band = Wireless-A/N Mixed = Connects instantly
2.4Ghz band = Wireless-N Only = Authentication error occurred
2.4Ghz band = Wireless-G Only = Connects instantly
The problem is clear. It's Wireless-N. I can connect just fine at Wireless-A speeds (54mbps max signal) and everything up to Wireless-G, independent of frequency, but as soon as I try to force Wireless-N onto my phone, it craps out and fails to authenticate. This happens regardless of whether I have the network encrypted or not.
And based upon my google search I have linked to in this post, I doubt this is something we can expect to be fixed anytime soon. Oh yeah and for the record, when I have my router set to Wireless-N only mode, I was able to connect instantly without error on my crappy old HTC Thunderbolt running a hacked together AOSP 4.0.3 ROM.
Yep............... GG Samsung
wireless n has been a unreliable joke since it was released...my favorite routers are the linksys wrt-54gl running linux dd-wrt firmware. one of the most affordable rock solid routers built. its only g band but most people do not need anything faster for home use. heck most of us cant afford the t1 type connection speed to utilize n band anyway.
Exact same problem as well...I'll have to try the Wireless N-only vs. Auto to see if that fixes it...
EDIT: Both wireless mode settings of 'N-only' and 'Auto' caused the problem. I had to set it to 'Legacy' in order to get the connection to stick without authentification errors. Have an ASUS RT-N66U router...
EDIT 2: Did the same thing on my Cisco E3000 and it worked as well.
Really looks like a Sansung wifi bug on the Note 2....

It's not Samsung. There have been issues with myriad devices and wireless N pretty much the whole time it's been around. Android OS or the the N standard-- I personally know people with other manufacturers hardware and the exact same issues. If it's an OS problem, you would think it would be fixed by now, but who knows, like was mentioned above, very few people need the bandwidth that wireless n can theoreticly provide.
Good Luck,
Jason

It's definitely something specific with Samsung and the N2 since my cousin's G3 connects to the same router on 5GHz WirelessN/Auto with no issues at all. I think they have a bug to fix...
Can someone else perform a check with their Note 2 on a Wireless N only setting? It seems this is a bug that really need to be fixed.

Has anyone else experienced wifi issues with their 920 where it's connected to the wifi, but there is no internet connection? It has been working fine since I got it back in November, then yesterday I noticed that when I was trying to open skype it just said connecting... forever. I tried IE and got nowhere, same with the people hub updating.
I eventually decided to reset the phone, and of course it then got stuck on the spinning cogs, so had to go through the whole mess of flashing the phone with the original EE firmware which did luckily bring it back to life. Then when it was running again, still the same wifi problem!!!
I eventually managed to get internet through the wifi again (for now) by switching the security from WPA2/PSK to Mixed WPA & WPA2, and then I switched it back to WPA2/PSK and it's kept on working now. But why did this happen in the first place as all my other devices (wife's iphone 4 and 5, surface tablet, latpop) were still getting internet through the connection no problem?

This sometimes happen to the L920, a reboot will fix the problem....L920 have still a lot of bug... so if you do not want to kill you phone, stay away from BAYGON
On what channel is your Wifi operating? I have seen People Report Troubles when their Access Point was set to operate on channel 12 or 13. Those are not available in all countries so that might be the reason.
Other than that I have no idea what the issue might be.
Reboots didn't help.
After a lot more investigation, firmware upgrades, tweaking of pretty much every WiFi setting under the sun, it looks like the issue was being caused by the two netgear WiFi bridges I've got attached to my sky boxes - every so often they randomly seem to interrupt WiFi connections from other devices - my wife's iPhone started having issues and when I necked the ip details, it had the netgear bridge ip as its gateway. Resetting both bridges seems to have solved the problems so will have to be my first port of call for any future issues!
