It's happening to me no matter what. Just sitting at the home screen or flipping through the home pages. Always there for me. I very much want ASUS to fix this soon.

I was wondering if anyone else have the same issue, I tried on my galaxys ,galaxy s2 and even on my galaxy tab 10.1 wifi could connect but there is no data transfer, I have tried this on several routers in my office but the result is same, is this a bug on android or hardware problem?

I have tried static IP, change many things but no chance, I even tried on different kernels but...

** my friends with blackberry and Iphone can connect to the same router and have internet :confused:
[Galaxy S II General] psp888:
most likely your office has blocked access through mobile devices
[Galaxy S II General] taha_e:
But as I say in the first post blackberry and iphone can connect :confused:
[Galaxy S II General] jamesa9911:
Yes I have the same prob, goes steady for ten mins, then just stops receiving a network connection, but my desire is fine. My honeycomb tablet does the same thing, but just turning wifi on and off fixes it. This appears to need a full reboot then works perfect again for a while. I've only had this phone two hours and have noticed it so surely others have.
[Galaxy S II General] eswar6280:
I too faced the similar problem in the beginning dude...later some where in the forum one user stated to reduce the security level of modem or router from WPA/WPA2 to WEP/AES...then it works flawless...i don't know whether it is a problem with android or hardware...but most of the router or modem is secured with higher level of security which could not be accessed by our SGS2..i hope this would be fixed by software update..
[Galaxy S II General] JJEgan:
Its is most likely router specific problem as its not a general problem and the majority have no problem with the highest security level .

It seems to be a problem with just some devices as indicated by this thread: http://xdaforums.com/showthread.php?t=1194635. For a high end smartphone worth £500, temperamental wifi is a problem i shouldn't have to put up with. My router has no problem with any other devices so it's clearly a fault with the phone.

[Galaxy S II General] temp9300:
That tweaker site is for GPRS/3g connection, this thread is about WIFI connection, so it won't help.

I have wifi problems as well. It connects just fine when i first configured the network but it won't work back from standby, although it still looks connected it won't transfer any data. Today i noticed an extra detail, it would seem that an app that was connected was still working but anything else i started fresh (like openinng the browser to access a page) wouldn't work.

I also noticed it loosing connection once after using it continuously for around 15 minutes.

Still haven't tried changing the security settings on the router, but, i previously had an ipad2 (for a short time, then sold it because it's just an expensive toy) and it would display the same behaviour.

Before that, i had a Nexus S with the same router and it always worked flawlessly! No settings were changed in the router.

I'm going to try lowering the security to wpa or wep and test it later.

If it works it might be a problem with the router but it's also a problem with the device (phone/ipad).

EDIT: one more thing, when i first got the SGS2 it had an older rom (vodafone KE7 i think) and it worked flawlessly until i updated it to a newer version the next day. I can't be to sure this was the culprit because i didn't use it that much the day before and it was a fresh install so maybe the issue didn't have time to show up.
[Galaxy S II General] taha_e:
one of my friends has a captivate sgs he also has the same problem, seems to be an android bug, or maybe samsung, another issue on this phone is about the bluetooth , it can not discover my headset bluetooth (sony DR-BT50) I have tried galaxy s , galaxy s2 and galaxy tab 10.1 but none of them can discover the headphone :confused: seems my galaxy life is messed up
[Galaxy S II General] zainqaiser:
Well i had similar issues with my vibrant and even on my nexus one....i think it is android bug....but if u r using cm7 or miui...u can easily get rid of it...by going to wifi settings>>>>advanced settings>>>regulatory domain>>>>change it to 14 channels....

but my sgs2 doesnt have this prob so far....i used those settings on nexus one and vibrant....and it worked....

Hope this helps..:)
[Galaxy S II General] eswar6280:
Hey don mess up man ...check whether that Bluetooth headset support Bluetooth v3.0 ...since our device is equipped with latest version of Bluetooth v3.0...
[Galaxy S II General] eswar6280:
I din state anything like it is a general problem...and moreover i tried with my Cisco wifi and with belkin router i could not able establish connection with my sgs2 where as my iphone4 connects without any issues dude ...so i concluded that it could be a minor bug and can be resolved by software update ...
[Galaxy S II General] steviewonders:
Surely it would be backwards compatible.
[Galaxy S II General] taha_e:
It should be meaningless if bluetooth 3 not support BT2.x many devices still using BT2.X, anyhow my laptop is bt2 but I can connect to my sgs or sgs2
[Galaxy S II General] varunkumars:
My Glalaxy s 2 has the same problem. It was fine till i was on KF7 but things changed with KG6 now.
[Galaxy S II General] fred_up:
My SGSII connects fine to every WiFi I've tried to join (open and ones that I know the password for). That is at least 3 different models of D-Link routers, a few Belkin and others that I can't recall.

I don't count a connection until I can actually view the internet and live stream the radio and I have been on it for more than an hour (I was proving to an ipad & ipad2 users that there was nothing wrong with a WiFi router and it was their toys that kept on dropping the connection).

I am was using the E7 and now F3 stock ROMs.

I did have a problem for about half a day. It would say connected to the WiFi but I couldn't get to the internet. I had to switch off the WiFi and connect via data connection and then try again with the WiFi - sometimes it would work sometimes it didn't. The only thing I installed prior to the problem was the Twitter app (from the market). Once I uninstalled that app and rebooted the phone everything was working fine. I can't say for definite that it was the cause of the problem.

To the OP: since you are connected to the work's WiFi, could the problem with not seeing the internet be due to the Work using a proxy server. That is what my work has.
[Galaxy S II General] jamesa9911:
Well I have a router that was supplied by imagine.ie, its a Motorola router and they with-hold the password to change settings on the router, have you heard the like????

Anyway trying that twitter suggestion, maybe the sync function was causing intermitttent wifi problems

Edit: Scrap them not giving out passwords http://www.imagine.ie/wimax_hub_setup.html
[Galaxy S II General] taha_e:
After a few hours survey I could connect my phone to the wifi, but Im not sure if this method works for you, anyhow I will explain here check it on your phone and report back

-Downaload the application "wifi static" from the market and install

-turn your wifi on and then run the application

-in the application choose add configuration,a window will popup saying have found a wifi connection will ask you to set for this connection or no just accept

-exit the application and turn off wifi

-turn on wifi and try to connect to internet,if you can connect then you are done if you can not go to below

-go to wifi static and choose the configuration which is already set and change the DNS I changed DNS1 to 8.8.8.8 and DNS2 8.8.4.4

-reboot (maybe not neccessary but recommended to do)

-turn on wifi and connect to internet and check if you still can not then...

-wait for me for further study
[Galaxy S II General] notabenem:
Static IP is a workaround

I had a very similar (if not the same) issue at home. Any other device could connect, but mine SGS 2.

So I downloaded Overlook FING https://market.android.com/details?id=com.overlook.android.fing&feature=search_result

and made it run.

It immediately stroke me that while the ip was: 192.168.0.104/24

and the DNS was: 192.168.0.1 the default gateway was set to: 192.168.1.1 (i.e. this was bad, wasn't on the same network)

I have triple checked every router/cable modem in the path. None was configured to run on 192.1.1.0 subnet. What I did not do was sniff the actual DHCP packets. Maybe it was because of a static route (see more in the links under Reason #1 below).

Anyway, without knowing the real reason, I solved this by setting the home router to 192.168.1.1 instead of 192.168.1.0.

Now on to the reasons of no data transfer.

1. Bad IP/GW/Static routes. Check with OverlookFING as above. Also see this thread: http://xdaforums.com/showthread.php?t=635489

and this (not really an) issue here: http://code.google.com/p/android/issues/detail?id=10315

2. Power management. Older wifi access points do not work well with clients that employ power management on the WIFI. For this reason I had to regularly disable PM on my notebook's wifi driver. For an unrooted android this is probably not possible to do directly in the driver, but I discovered a setting in the API that allows the WIFI to work without PM. I am using it currently as a widget. Does not do miracles, but helps most of the time.

3. Something else...
[Galaxy S II General] varunkumars:
I tried all settings but i works for a while a goes away while phones connect to wifi. My wifi shows connected too but can't open pages.
[Galaxy S II General] jamesa9911:
Hmmm I seem to be getting better results with using 8.8.8.8 as a secondary dns....And using 11 channels as regulatory domain(but dont know which is best), I'm changing all these via MIUI btw.

Edit: Or maybe not, problem has returned as normal. slightly off topic, but why am I seeing android os and android system take up 24 and 21% battery respectively, all other apps/cell standby/dsiplay have their own battery usage....

Note that anroid system points toward telocation, google backup, sync and vpn services as among the battery users("included packages")...
[Galaxy S II General] chaoscreater:
i'm having problems too, although i'm using a Milestone instead of SGS2. I only just got the Milestone yesterday and already having a lot of problems with it, not a great start to using my first Android phone if I'll be honest....

I rooted it and installed custom rom on it no problem. Wifi works fine on it too. However, I don't find any benefits in installing a custom rom other than its speed. It lacks some basic stuff that I need to get used to first as a new user of Android. I had to install gAPPS on it, and then the Android Marketplace .apk file just so I can get the simple Android Marketplace app on it.......and even then, I couldn't use it coz I need to create an account for it. I tried that, but it doesn't work, it just keeps saying server couldn't connect or something.

So I reverted back to stock, and now I have this stupid wifi problem.
[Galaxy S II General] shafraz:
Well, I have been looking for a way to disable PM for Wifi on the SGS2, but so far the only post I bumped into is yours. Can you please tell me how to do this? Whats the API?

Would you care to share your Widget? I'm sure it would be helpful for most of us? If not, do you know any product that would do the same? (Disable PM for Wifi for the session).
[Galaxy S II General] varunkumars:
Finally i resolved it i installed wifi static app from Market and selected(tick) Force apply and turned on the wifi. I saw note" DHCP starting" and it worked flawless. Hope it helps .
[Galaxy S II General] shafraz:
Good for you! Looks like the problem you were having was DHCP specific. Forget the app and try adding a static IP manually in the phone settings itself. Does it solve your problem? In that case, it should be a simple DHCP issue.

Other issue most users face (including myself) seems to be due to the Power Saving mode of Wifi. Some older routers cannot handle this / don't like this, and the connection drops every now and then and there is no data flow.

At home I use an older wireless router and I see my SGS2 connects with Power Saving active, and the connectivity is really bad. At office I have one of the newer routers which handles Power Savings without problem, and the Wifi speeds are just phenomenal.

So for rest of us who are facing the issue due to power saving mode (and may not know it's because of that), we should find a way to disable power saving on the SGS2 for such routers.
[Galaxy S II General] Psilocin:
Took me a while to figure this out. I don't have a router in my dorm, so I use the mifi on my laptop to tap into the internet. The connection breaks very easily, especially after waking up the computer from sleep and reconnecting back. Wifi on/off would work sometimes, but is pretty tempermental at best.

Fixed the problem by switching to WEP password encryption instead of WPA/WPA2. Still quickly disconnects/reconnects every once in a while, but usually only once every couple of hours.
[Galaxy S II General] Ammarooo:
i tried it too and did not work the wifi still connected and no data transfer and i tried to update to 2.3.5 and still the same and also the wifi is so stupid it cans see the adhoc networks i dont know what the hell with the wireless in the galaxy s 2
[Galaxy S II General] taha_e:
Ad-hoc and wifi problem are 2 different matters,

For some reason Google or phone companies dont like to add ad-hoc support to their smart phones but there are some wpa_supplicant files which will allow u to have a wifi connection with laptop or ... to share internet

the wifi matter is quiet different here its a failure in security checking while trying to connect seems that android still has a long way to go
[Galaxy S II General] shashankdombe:
Is there any support for the Adhoc network in future updates..

When we are connecting to wpa2 enterprise connection other than setting security type and all whether we have to se access points also...??

Thank for the Overlook FING. I missed this tool ;)
[Galaxy S II General] shashankdombe:
Can someone please explain the above things in little bit simple lines. My GS2 will connect but no internet access.. But colleagues Blackberry is working. I cant set up any static IP as its office network wpa2 enterprise. Then How can I change the IP settings? or whether changing lease time in router to 10 min will solve everything.?
[Galaxy S II General] netokee:
It seems that the SG2, at connection on some WiFi network, don't stetting up correctly the Gateway IP address received from some router.

At home you have one Gateway to go on the Internet: your router.

If your GS2 have a false Gateway, it isn't able to open a connection to the Internet. That the reason why your are able to see all other network component in your home network and nothing on the internet.

And why the lease set on 10mn could be a "half solution"...it would seem that arrived the end of the lease, the GS2 should update properly all IP SETTINGS, including the Gateway IP address. And this, all 10 minutes.

The default value is generally 1440 minutes ;)

Voilà

This happened to me today, I was most unimpressed.

Unable to download from market via wifi with proxy

Hi, I am a new user of SGS2 and I am facing the proxy setting problem as many people here have. In work I am able to connect via WiFi without problems and I can use everything - there is no proxy. In the student residence I use WiFi from my notebook (using Connectify program). From our network I know, I have to use the proxy setting - that is no problem to set it up in Advanced Settings of Wireless connections in my SGS2. After that the browser is OK and I can browse the internet. But no applications can use the proxy. SO, I had found a help on this forum and rooted my phone. After that I installed ProxyDroid. All right, some more applications can use the connection - even the AndroidMarket. BUT, there is a problem - I can open Market, find searched app and learn about it. Unforunatelly I am not able to download and install anything from the Market.

I really don't know, what to do with it. Downloading from the web browser is all right. I can see videos on YouTube in browser, etc.

So probably there is some problem in ProxyDroid, or something with download process..

I am absolut novice in android, so most likely the problem is very simple, but...

Thanks to anyone, who can help me :)

Solved... with ICS..

Hello guys,

I was facing this issue from long time and I couldn't figure out the solution till yesterday. I saw the official release of ROM for SGS2. which is XP8 android 4.0.3.

I flashed it and when I reconfigured wifi in office using the domain pasword it connected without a glitch and I got the internet access too.. I happy with the ICS. But still its a testing and unofficial build, not recommended for daily use..

Below is the link for ICS 4.0.3 GS2..

I have exactly the same problem. The funny thing is that I have a SGSI and a SGSII, both with ICS. The problem is only with SGSII, and it appears not only on networks with static IP (like my office), but also on many public wifi networks. Practically, the only place I have managed to have internet on the phone while connected with the wifi is my home and some other home networks of friends. All public networks and in my office, I get connected but no internet. I have tried all suggestions, many widgets and wifi managers but without any success...

[Nexus S Q&A, Help & Troubleshooting] :
Oh boy. I've done something ..interesting.. to my new nexus s. Could you guys help me?

Okay, So I've been running miui for about a month now, and today I decided I will try the oxygen rom, along with a new radio (K3B). I flashed the radio over miui and all was fine.

Next I wiped and installed oxygen. No service. I couldn't even view available networks. I had a play around with the service menu (*#*#4636#*#*) and changed regions etc, but no luck.

The next thing I did was to try and revert to stock, by following the unlockrs guide (http://theunlockr.com/2011/01/20/how-to-unroot-the-nexus-s/). This seemed strange to me, as it was only a nandroid backup. Now I'm on 'stock' with no cell radio and a small wifi only tablet.

So, my real question is, can I fastboot or ODIN back to complete stock (radio, system, recovery, etc) or are there any other fixes for this problem?

Thanks! I'm desperate :S
[Nexus S Q&A, Help & Troubleshooting] rentaric:
Which Nexus S you got? Which ROMs you flashed exactly? Which radio did you flash, never heared of KB3b?

I'd assume you have a i9020T (since you used the GRH78 nandroid backup)? Then you could use the ROM in my sig to flash back to stock.

However, I never flash any nandroid backup that isn't my own, especially if they are crossing release numbers, eg 2.3.5 to 2.3.3.
[Nexus S Q&A, Help & Troubleshooting] :
I have the i9020T, flahsed the XXKB3 Radio (see here: http://xdaforums.com/showthread.php?t=1116884).

I don't think flashing back to stock helps too much :(
[Nexus S Q&A, Help & Troubleshooting] rentaric:
Go here and get yourself a flashable full ROM for the i9020t, it will include a fitting radio (and a stock recovery). Remember to wipe everything before installing the ROM via cwm recovery. I'd also format stuff in "Mount and storage" (except sdcard for obvious reasons :D).
[Nexus S Q&A, Help & Troubleshooting] :
Tried that. No success. I also used ODIN to revert to stock again. No success. Tried all the radios available for i9020t, none of them work.

My IMEI is intact still, my baseband /should/ be working, I really don't see anything more I can do except assume its a hardware issue. I'll give samsung a call now and see what I can do. Thanks for your help.
[Nexus S Q&A, Help & Troubleshooting] rentaric:
Maybe your carrier banned your IMEI for w/e reason.
[Nexus S Q&A, Help & Troubleshooting] :
I've tried multiple sim cards, and even if my carrier did block me (why would they do that?) I would still be able to at least view other network operators (and mine) in the Mobile networks menu.
[Nexus S Q&A, Help & Troubleshooting] rentaric:
Well multiple sim cards NOT working in your device could mean your IMEI is banned. Carriers block IMEIs for several reasons, stolen phones, contract abuse, carrier crossing, unpaid bills, etc etc.

Contact them and ask. If they didn't block anything you're still one step closer to solving the problem, next step exchange the SIM card, final step would be to contact Samsung and have them check for faulty hardware.
[Nexus S Q&A, Help & Troubleshooting] :
I'm starting to think thats the case.. My original sim card is dead and won't work in other phones now.

What I really don't understand is why they would blacklist me. I've been with my carrier for two years, since they started up. I'm a prepaid customer, so no unpaid bills. My phone is brand new, purchased it at Best Buy in the US four weeks ago

Maybe they were mistaken? I'll call them later in the day.
[Nexus S Q&A, Help & Troubleshooting] :
Ugh. I talked to my service provider, they said they couldn't do anything and were very unsure. They handed me over to samsung, who were unbelievably unhelpful and told me to turn my phone off and on, and that they couldn't do anything more. Just sent an email to my service provider hoping I get someone more 'higher up' who can deal with it.
