SGS1/SGS2 Wifi connects but no Internet data transfer

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

most likely your office has blocked access through mobile devices

But as I say in the first post blackberry and iphone can connect

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.

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..

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://forum.xda-developers.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.

Never had an issue with wifi and wpa / wpa2 on multiple hot spots and home. Try a factor reset and flash . On kf3 xeu

http://tweakker.com/wizard/step1

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.

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 seems my galaxy life is messed up

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..

Surely it would be backwards compatible.

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

My Glalaxy s 2 has the same problem. It was fine till i was on KF7 but things changed with KG6 now.

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.

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

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

Loosing internet connection over wifi

hi folks,
this happens both my nexus 7 and galaxy nexus from time to time. While connected to my home wifi they will loose internet connection. They are still connected to my router as i can ping devices on the network. I have to disconnect and reconnect to get net access back again. Im using WPA2 Personal encryption on the routher with tkip/aes
Anyone else experience anything simillar? I have no issues on my work wifi.. it stays connected all the time
Cheers,
Mick

I'm curious about this too. Been having the same problem. I've tried two different routers even went back to stock. I use shout cast on winamp when I sleep. Wakes me up when the music stops.

Its frustrating as my 7 and Galaxy Nexus are solid as a rock on wifi at work.. both experience the issues at home. I'll try boosting the power output as suggested here tonight and see how it goes
Comment 31 by lamyjeanfrancois, Aug 16, 2012
Changing home router to a wrt-based asus rt-n66u and boosting the output power to the maximum US allowed value of 100mW fixed it for me. Other devices were working fine, even lowly archos 28 mini tablets. It seems that jb is misinterpreting signal strength.
I dont want to run a static IP.

Cheers,

Some testing last night, i upped the output power on my ddwrt router - that didnt stop the issue from happening. Then i went with a static IP. This seemed more stable but i still lost connectivety at one point, only for it to return on its own - before i would have had to connect/disconnect from the access point to restore internet. More testing tonight.. its very frustrating! I dont think its a hardware issue as its happening with both the Galaxy Nexus and Nexus 7. Anyone else having simillar issues?

Same here
I Experience the same, happens almost every hour or so.
All my other wi fi devices have no problems, just nexus 7

Hehehe it seems many of us having wifi range issue. I checked my wifi signal strength thru wifi analyzer app and it seems wifi is solid if only I always have more than -40dBm strength. Which means I needed to be always closer to the router, can't make it when I'm already at my room. Quite annoying but I guess I had to send it to service center.
Tapatalked from my Ace 2

Same problem here....
Weird thing is I have 2 routers connected to each other (dhcp off on second one), having same problem on both routers. I thought it was the internet connection as my HTC Desire does the same thing.
I also tested the nexus 7 wifi with my 3g Desire via hotspot.... and no issues at all for 3 hours+.
So i'm pretty sure its not a nexus issue, unless there are some compatability issues from my nexus to the router.
Ideas anyone?

using static IP at home seems to be stable.. cant understand what different though between work and home that it works fine in the office.. must be a config parameter on my access point at home

Stock Android does not support WiFi direct. It uses bluetooth to transfer. I would try the Superbeam app (You have to install it on both phones). Are your other phones working on the 5GHz WiFi band? If so, what channel is your router broadcasting at? Some people have issues with the Nexus 4 not connecting to bands 12 and 13 (if my memory is correct), but not all (My 211k Nexus is fine). Are you running stock? If not, what ROM and kernel are you running? Have you tried to disable WiFi optimization (Settings>WiFi>Menu button>Advanced>WiFi Optimization)?

I recently moved to another location and found out Nexus having hard time to connect to Google through Wifi(grey wifi bar appears often). Surfing internet is also dramatically slower than before. I do not know if it is Google I/O related issue (namely software issue) or router (namely hardware issue)?
All my PCs and another Samsung Android phone work fine with the new router. What's happening?

Nexus 4 Wifi Issues - connects to router but no internet

Just want to know who else on XDA has a similar problem to me on the Nexus 4.
Recently moved country and took my Nexus 4 with me, got a data plan, no problems there. I was also was given the stock router for my ISP (Movistar) when taking out my broadband contract and my Nexus 4 is the only device that won't connect to wifi.
So here's what happens:
1) Network can be seen on the Android 4.2.2 Wifi Settings
2) I can connect, either by WPS or by entering the password, and Nexus 4 shows connected with indicator
3) Indicator instead of being the standard blue is grey, which seems to be no internet connection. I can get some access but at very, very slow speeds (about 9kbps)
The Nexus 4 is the only device in my house with the issue, no problems on PCs, iPads, etc.
Google have acknowledged this is a bug and there is a fix which involves root, but I don't want to root at the moment. Google also say it'll be fixed in the next update, but they've said that and we've seen 4.2.1 and 4.2.2 come out in the meantime.
Google Support also sent me a rubbish response to my questions about when it'll be fixed, telling me what Wifi is and how to turn it on and off..
So just want to know, are you having the similar issues with certain routers on 4.2.2 (stock)? I know I'm not the only one but I couldn't find any other threads.
Thanks!

I started having this same issue man! care to show me whats the root needing fix?

There are a lot of fixes in the Android Development Section.

Typically this can be a DNS problem if your router is not correctly set up to relay DNS requests (windows/OSX tends to be a lil smarter about it if it can't get the appropriate response from the router).
You could try to set a DNS yourself such as google's public ( 8.8.4.4 and 8.8.8.8 ) in the advanced properties when you long press the SSID you're connected to and see if that allows for internet access. If it does, then maybe you just need to log into your router and correct the DNS info.

Thanks for the responses guys

Tried that I'm afraid :/ No luck. According to Google it is the fact "they have no drivers for that router" considering they will probably have a generic driver for the average user to connect whatever the router.
Sadly I've had to practically try everything to get it to work. Thanks so much for your response though!

Hi! It's an annoying issue, I'm currently tethering through Mac to get it to work. The root fix does work but drains battery life a lot more (instead of 0.5% per hour drain it's 5%). If you want to look I'll pass the link, but wouldn't recommend it.
Thanks!

See if you're able to do a traceroute from within android when connect to the router to see where it's failing.

Mine got fixed by changing the routers channel, weird cos' no other thing connected had a problem, not even my sister's nexus 4

Hi, tried this and have no problems. The only issue is it takes too long to complete, which is the 9kbps download issue I was having. I'll attach a screenshot of the traceroute if needed. Thanks for the reply, much appreciated!
And about changing routers, not possible at the moment. I've just moved abroad and have my old router somewhere too hard to find. Google are no help with this which is the problem, but if it persists in the next update I'll get a new router whatever the case.
It's strange since my iPad and all my other devices work with no problems!
Good luck, hope yours works now!

Yep it's a common problem I'm afraid which is obsolete in the eyes of Google and not a device defect...
Just to get an idea, what router models are you using? I'm on Movistar's stock router - ASL-2665 - common issue with this router. I've also heard big brand routers having similar problems, anyone got any problems with a particular router?

The Nexus is a great phone, just a few odd issues which hopefully will be fixed.
This issue is persistent but dependant on the router. For example, my extender works perfectly whilst the main router doesn't - let me know what your router model is and I'll check to see if this will be common for your router

Hi!
Taken a quick look and doesn't seem to be any problems with your router. What you can do is to purchase the device and test to see it works on WiFi.
If it works, you're good to go!
If not, try some troubleshooting, so change channels, IP address, or even just a reset of the router could work.
Still not working? You can try what I did and buy an extender, but that'll set you back a bit of money.
You could wait until this is fixed, which we don't know when yet, or if you can't fix it you have a return period on which you should get a refund from Google.
Let me know what you decide to do, personally I'd try it out since it's likely to work, but I would return if not. But the Nexus 4 is a great overall device for the price.
Hope this helps!

OP, have you checked to see if this is an issue with the wifi access point of your router, or actually a routing issue?
To do this, set up ftp services on your computer or phone and login from the other device and copy a file from one to the other. If the bandwidth is good, your problem isn't with wifi but rather a routing issue that can likely be addressed in its settings.

I'm about certain this is to do with the router itself and not a routing issue, this is a common nexus4-my router problem and various other models.
I've adjusted every setting possible in the router settings to no avail, and all of my other devices which include other android devices work perfectly.
Sadly it seems to lie with a Qualcomm driver from what I've seen, and hopefully Google can fix in the next update

If you don't bother to check if you have good throughput over your LAN, you'll never know whether this is a wifi issue or a routing issue.
Drivers talk to hardware, i.e. Your wifi chip. That is all local, and has nothing to do with the routing (Internet) part of your router. Without knowing where the actual issue lies, you're just guessing if a new wifi driver will help.

Sorry, you seem to have misunderstood me and you're obviously making the assumption that I haven't already checked for routing issues.
As I said, my Nexus 4 is the only device in my house with this problem, all others work perfectly. From what I've gathered from these issues, it lies within the drivers of the phone.
WiFi works perfectly on every other router I've used with my N4, it's only my home router with the problem. It's a Movistar default router and other users have the same problems with this router (the brand is fairly unknown).
And I'm definitely not guessing that it's a driver issue - I've had this problem for over a month, I've tried everything I can: changing router settings, resetting, etc. So I doubt this is a routing issue but more an issue with the device, and from what I've read on other forums, this could be down to a Qualcomm driver issue.
Thanks for your help anyway!

I am not assuming anything. Simple troubleshooting 101. You're not getting a decent Internet connection. Could be wifi or router. I merely offered a simple method for determining which one.
Don't know who you spoke with at Google, but first couple of support levels don't have the stones to try and solve these things. And while I have no doubt other folks with the same setup are also experiencing this issue and that Google has recorded this info, that doesn't mean that a workaround is impossible.

Wifi not working correctly

Hello people of XDA!
I had my note 3 runnning on CM11, suddenly it wouldnt connect to my router 5ghz network anymore but it did fine on the 2.4GHZ i tought it was a CM11 bug so i restored back to TW now i can connect to the network but my Download speed is really slow (about 1-2 mbps compared to my laptop wich speedtests at 50 Mbps running the same wifi)
The question is: is my note broken (again) or what should i do ?

Great now i cant even connect to the 5GHZ network, if somone kind would help me i would be thankfull!

(You havent changed any settings in your router lately ? )
You tried rebooting ?
If wifi isnt working at all one of your last chances might be a backup + wipe system/clean flash of current ROM.

Use wifi anyalyzer on the play store, and see what channels other routers are using, if they are on the same as yours and there is an empty spot somewhere, try changing your routers channel to a free one.
I have had many issues in the past due to this, damn neighbours! Haha
This may not even help, worth a try.

I have had many issues in the past due to this, damn neighbours! Haha
This may not even help, worth a try.

Well im the only 5ghz network here nearby according to Wifi analyzer, strangely i can connect to the 5GHZ via wifi analyzer but after i exit the app it disconnects... Weird...

Could be the location settings under Google settings, caused me problems with glitchy internet in the past. Switched it to gps only one time and after that to desired setting and it solved the issue for me.
Hope it helps.
