Hi All,
I have a very odd issue.
My phone can connect to my wifi router no issues. When it first connects it will browse and receive services from the internet no issues. However, after maybe 1-2 minutes all internet service requests die, the phone is still connected to the router as the wifi signal is there and strong.
I have tried changing the security on the router, updating the kernel / rom and i still encounter the same issue. I'm convinced this is a small bug.
If anyone has come across this please let me know how you dealt with it.
Thanks in advance
are you on stock ROM/kernel? Does it happen after you turn your screen off and back on?
Had same problem, router issue something about firewall, had to manually enter phone's Mac address into router

On a stock kernel using warrior rom. But i have tried different combos but with no success.
Have now lowered security level on router after reading some posts, now just doing tests.

I've reserved the address on the router that includes the MAC
Seems as though security setting above WEP e.g. WPA-PSK/WPA2-PSK/WPA-PSK [TKIP] + WPA2-PSK [AES] causes the issue.
Anybody know of a fix for this?

Hi guys, in this days i have noticed a problem with my gsII.
Sometimes I have the gsII connected to my router but internet connection doesn't work.
I'll try to explain better what i mean... I start wifi on my gsII and use internet connection without problem. Then I set the phone in standby mode leaving wifi on. When after a while i want to use internet connection, it doesn't work. The telephone is still connected to my router but i can't use internet on the phone.
The only way to make internet connection work is to disable wifi e then reactivate it.
This is really frustrating....
I've got the telephone from three months but only now I'm noticing this problem because first I used to disable the wifi and activate it only when i need it.
Am I the only to have this problem? Is there a solution?
Thanks to everyone in advance... any help would be appreciated
A video is more than thousands of words, so this is an "example video" of the bug:
http://www.youtube.com/watch?v=4um-AqLk1jw
Test it with a different router, i.e. Cisco E4200.
It would a good idea but i have to buy a new router or go to some friend's house for 2-3 hours. I'll keep this idea in my mind thanks
I have this problem, mines a bt home hub v3. Don't think its the router I blame the phone. I have to restart phone to make it connect with ability to use internet

I do not know what " standby mode" is? I have the same phone and have no problems with wifi. The phone goes to sleep when I do not use it and awakes when I use it.
It seems that your phones wifi is sleeping and not waking up. I always turn it off when not using it anyway. Not the full answer but it works for me.

I don't use wifi very often, but I do notice this problem with 3G data. Modem problem? I'm using kh3.

I believe I know and had the problem you describe.
For me the Wifi would work perfectly at first and then after the phone had been left for a while I would try to use it and get 'no connection' type errors. Sometimes it would even stop working even if I just waited too long with the phone still on in my hand.
I found that if I either disabled router wifi security or set it to WEP the problem disappeared. The issue occurred on 2.3.3. My router is a DLink one fyi. I have yet to test 2.3.4 which came out yesterday in Sweden. Ill let u know.

Ehm...For standby mode I mean that I lock the phone, I only shut down the display....understand what I mean?
If you turn wifi off when you don't use it, you'll never see this bug. Try to leave wifi on for some hours if you want to understand if also your gsII has this bug.

I tried changing the channel also. I have heard others getting this to work. Didn't work for me. You can use Wifi Analyser app on phone to find a clear channel and see how u go changing your router perhaps?
I tried re flashing also using factory restore. No fix for me.
Also noticed that u can sometimes get phone to work by toggling Network Data on/off. Not really fun either.
The wifi channels and security settings I am talking about are settings in the router not the phone. What wifi security are you using in your router?
Sent from my GT-I9100 using XDA App
I am not a believer the router is at fault in any case. I would entertain an incompatibility but nothing more.
Original router and security settings work fine for...wait for it...an iphone 3gs and a Motorola Defy (yes the phone which seems to have issues with doing everything else!)
Either way an incompatibility is not acceptable either if that's what it is

I know this, and in fact i have to switch off and on wifi connection when this happens.
Now i'm trying to use channel 5 with the router ( but yesterday I've tested channel 6 and 13 without any result)
I hate this bug because beacause it happens only when he wants! I'm quite sure that assistance wouldn't solve the problem. A friend of mine has changed three gsII and said that every gsII that he has changed had this bug!
Ps: Another question.... How often do you have this bug?
Once a week? Once a day? Three times a day?

Is NOT the phone.
i have the same problem reported in the 1st post.
i have been turning wifi off and then on again for a quick fix until now but i think the solution might be to drop the security on the router from WPA to WEP. Haven't tried it yet tho, because it doesn't bother me that much.
I had an ipad previously (before i had the SGS2) and it had exactly the same behaviour. I looked up the problem then and found a FAQ from the ISP that mentioned a compatibility problem between ipad and that router, so their suggestion was to set the router to WEP only.

Easily more than 3 times a day but then I use the phone a lot.
Problem had never occurred when I used only 3G. That was my workaround when I got fed up with it before I dropped the wifi security.

For me it happens always after the phone comes back from stand by with wifi on.
steps to reproduce:
1-turn wifi on, and check it's connected and working
2-press power button to turn off screen
3-turn phone back on, try to access a new web page, it doesn't work
I noticed that while it's in stand by i will still receive email notifications so it probably only looses the connection when i turn it on again.
Also, if there was some program working (say, a download) when i went into standby it will probably still be transferring when it comes out of stand by, it's just the new connections that fail.
I have a samsung galaxy tab 10.1..
I am having trouble getting the wifi working on it.
my tablet shows that it is connected to my wifi connection , but i am not able to use the internet. The wifi icon also appears grey rather than blue as it should..
Please help me out.
Thanks in advance.

I'm getting often wi-fi drop outs throughout the day and the only way to fix it is by restarting the router?!
Restarting the phone doesn't work
Turning off/on the wi-fi doesn't work
Switching bands doesn't work
yet it still allows connection to BTFON/BT OPENZONE? But won't connect to my broadband.
It's kind of annoying, because on the status bar it shows that it's still on wifi but going into settings and turning it off/on then shows it's not working. As it won't connect to the internet obviously.
Anybody else getting this? Any fixes?!
Thanks.
I have an issue where it just briefly drops the connection and reconneca, sometimes it is connected but can't access internet unless I cycle wifi.
I am on the Optus, Australia S3.
I have tried it on both my access points, it can't sustain a Skype call-keeps choking up-I am hoping a new kernel or custom ROM may help-tried Omega, but had barely any phone signal.
I have sleep set to never, have tried 2.4GHz only....a bit annoying, but Ireckon it should be sorted soon. It is the only issue I have.

Try changing the security type of your router. It's often better to pub less encrypted seucurity. For instance try removing security completely for a few min and see if the problem carrys one. Then it means the problem is from the security of your router and then change the type of security to something different than it was before and should fix it. good luck

Hmmm i just changed it from WPA2 only too WPA & WPA2.. seems to be working at the moment.
I'll report back later.
Is it a bug that it doesn't support WPA2 or something?

Oh No it's not a bug! Some times different routers are not well at making a steady connections with certain devices through high encryptions. As you remarked the problem is not an issue incase of connecting to BTOpenzone and yes pretty much. This problem can often be solved without the need of even purchasing a new router. Simply head over to your router's setting page (should be something like 192.168.xxxxxx) then see if it's possible to upgrade your router's firmware.
See this link, maybe it will give you an idea of what I'm taking about

I'm assuming you're using a bt homehub of some sort?
I'm using a bt homehub 3 and I've been getting constant drop outs when downloading files over wifi.
I tried a lot of different fixes and was clsoe to throwing the phone out of the window lol
What seems to have solved the drop outs for me is using wpa instead of wpa2.
Try a factory reset?
I'm also on a BT Homehub and i haven't had a single problem, i did a factory reset as soon as i got the phone to prevent any issues.
I can't seem to connect to my router at home. I'm able to connect to another router closer by,but not mine.I've tried changing encryption type from open to wep, to wap. But no luck. Every time it attempts to connect it says authentication problem.

Try looking at your router logs when the error happens to see why it's not authenticating. Try rebooting your router.
BTW wep and wap are not recommended for authentication...that **** can be cracked by a 12 year old. Use WPA2 personal.

So what youre gonna want to do is open your logs, clear them, try to connect on your phone, then look at your logs to see if the router even sees the attempt. It should show any errors as well.
What does your phone do when you try to connect?
edit: couple more questions...can anything else connect to your router? Also, your router is also a firewall. When you log in you might try and disabling the firewall feature altogether and try connecting.
I'm gonna try the logs now, and yes 3 computers are connected wirelessly. Also the phone says connecting...then says authenticating problem. I know my password is correct for sure. I'll check the logs now

Thats strange. Your router *should* be logging auth issues.
Have you tried forgetting your wifi network on the phone and reconnecting as new? And yourer showing password to make double sure its correct? If it is, the auth issue is probably a security mismatch. Router set for WAP, youre trying to connect with WPA2, etc. Double check your router how auth is set up.

Can your phone connect to other routers/AP's using the same encryption? Or do you know? Possible your keys are corrupt.

Have you updated the firmware in your router? If so, check to see if there is any new firmware. Also what is the bit length of your passphrase? 8 or more characters. I would also have your encryption set to WPA 2 with AES not TKIP. Also try setting the channels from auto to a fixed channel, start with 1 and go from there.

I got my HTC One today and I have exactly the same router and I have exactly the same problem. Old LG 2X would connect like lightning. Tried different encryption, reset router multiple times, nothing.
Sorry if it is an old thread. sorry for bump.
I also had this "Authentication Problem" issue on my HTC Pico a few days ago.So,I also tried restarting my router, changing password and stuff like that. but it didn't worked.
out of curiosity I then switched my phone into airplane mode and waited few seconds and then back to normal. to my surprise, my phone automatically got connected to the wifi without any hassle. and hence problem solved.
It seems like my phone sometimes isn't able to obtain an IP address over wifi. I can see in my router that is has been authenticated. The only way to solve this is a reboot.
I know it's not my router that's causing the problem, because I also had this problem at my parents house.
It started happening after I updated to .402.
Does anyone else have this problem?
