General :: WiFi Connected But No Data?
Jan 16, 2012
I have a Droid X running Gingerbread, and there is one particular WiFi spot that seems to hate me. It's a WiFi router owned by a friend of mine, WPA encrypted. I have the SSID and the password, I can connect to the router. And my network icon turns blue indicating that I have a connection to the Google services. But I can't browse the web, I cannot send/receive email and I cannot use any other app that uses data. Another friend with an iPhone has no problems. My iPod Touch has no problems, but the stuff I want to use is on the Droid.
Two additional kickers to this: My late and unlamented Blackberry had the same problem His router is the same brand (and I think model) as mine and I have zero problems with mine.

I am trying to conduct a bit of research before starting to develop an android application I am planning. I want the application to exhibit the following behavior:
If connected to WiFi, send and receive messages to remote server.Else If not connected to WiFi, do not send any messages. Display error message.
I am trying to create an ethical application so users will not be charged when they become disconnected from WiFi without them noticing. Any existing source/documentation on how to do this.

Is it possible to use the cellular 3G data network while connected to WiFi? I want to create connection through the 3G network while WiFi is also connected.

I have just upgraded to Android 2.1 on Orange(UK). When I connect to WiFi (home WEP and open), it says I am connected - shows IP address etc., but nothing actually works through the WiFi - can't sync Exchange email, can't download from market, won't even update location on Google Maps. If I switch WiFi off everything works fine over mobile network, but that is unsustainable due to data charges.

I've had my desire for around a month now & had no real problems with it, flashed it with a stock ROM initially & then rooted it a couple of days after the root was released. When I woke up this morning I was connected to my WiFi network but when I tried to load a webpage, nothing happens, it comes up with the stock 'Web page not available' page. I tried a couple of web pages but got the same response, I thought it might be my WiFi network but when I got to work, exactly the same thing happens. I can connect via GPRS when I disable the WiFi with no problem. I've been using Y5 Battery Saver for the past two weeks, not sure if that's relevant. Is this a standard error / known bug, how would I go about fixing this, not having WiFi is obviously a bit of pain!
OK, installed a Terminal emulator over 3G & ran a couple of commands, including dmesg. From the output of dmesg it looks like the WiFi connects but then something goes wrong, here's a brief transcript:
pfn: set ssid = ******
Link event
Link UP
Enter set packet filter
start to add pkt filter 101
wds: 0021 @ 01
qmi: wds: network stopped
rmnet_stop()
wds: 0022 @ ff
qmi: wds: DISCONNECTED
If this is any use, I'm happy to try other commands.

My HTC Desire (UK) has been find ever I had it, no issues whatsoever. Recently updated the Android software and ever since then I can only access the web/market etc when connected through wifi.
My signal bar simply shows bars whereas in the past it had either a G, 3G or H next to it, and I'm guessing this is linked into the problem.

I wanted to give Android a try after having an iPhone for about 4 years now (1st generation iPhone). I decided to go with a used "China" phone - Hero h300 because I didn't want to splurge and find out that Android wasn't for me. So far I do like it but I am running version 2.2.1 (Froyo) and am having an issue with the WiFi connection. I'll initially connect and after a random span of time it will start failing to load pages when browsing or the market will report that there was an error (or lost connection) even though the phone still shows a WiFi connection.
I do not have a data plan and am using WiFi for connection and have setup the phone to use the WiFi instead of Sim data connection. I use WPA/WPA2 PSK security for the wireless network. If I turn off WiFi and turn it back on (on the phone), it will reconnect and work for a while but the problem comes back. So while I "surf" the internet or Market, I have to constantly turn the WiFi on and off.
What can I check or try to resolve this issue? I actually had bought this phone because the iPhone's WiFi was going loopy (it would just scan and scan and scan and never find any networks - even if it was literally sitting next to the wireless router) - so it's kind of ironic that the main problem I have with this phone turns out to be it's WiFi

I just flashed to jelly bean 4.1.1 on my verizon GS3. I can't get wifi to stay connected. It continuously rotates between "Authenticating", and "Saved, Secured". Eventually it gives up and just says "Disconnected".

I live in India. I had purchased a new TP LINK wifi + modem router last week. The modem works great as I access internet using my PC ( ethernet connection broadband) . I tried connecting WIFI using my android, but even when connected I don't get internet on my device.
Here are some screenshots of my modem settings page ( when my android galaxy mini is "connected to wifi, (no internet though))
Status :See my android phone in list of wifi connected clients
And in that WAN tab, why that PVC0 status is down?
In LAN settings photo modem shows my device android connected to modem, but still no internet.

I am able to find and connect to my Wifi Network at home, but internet connection between my new Android Tablet and Wifi is slow. My apple devices connect to the same router and are able to browser fast, the android tablet also browses fast with other Wifi network. There is something between the combination on the tablet and my wifi router that is making the connection slow (the google homepage takes forever to load so does other sites).
Tablet runs Android JellyBeans 4.1 and Wifi is secured using WPA-PSK (tired AES, TKIP and even open connection)

I came back home and connected my Galaxy Ace to my home wifi, but this time, it wasn't transferring any data.. It would be connected, full signal, but no internet connection.. My browser, gmail, YouTube, PlayStore, nothing would load.. It'd keep saying Connection Error. Retry. My WiFi works properly on the computer and other devices, and my phone used to work perfectly too.

I perused the play store looking for an app that will notify me whenever I connect to a specific wifi network but didn't have any luck.
Why I'm looking for this functionality
- i'm on a wifi only plan with my carrier
- my work has a wifi network but it requires me to provide login credentials before it is useable, so I'll be connected to their wifi network but I often forget to login to make it useable.

I currently have a jailbroken iPhone 4 and am about to get a HTC One. I used MyWi to tether a WiFi signal while connected to my house's WiFi network to my laptop via USB. I want to be able to do this with Android as well.

I am looking for an app that automatically switches off the cellular radio when wifi is connected and switches it back on when wifi loses connection. I'm not talking about the APN data connection which already does that, I'm talking about the regular cell phone connection.
According to my lack of results searching through the forums, Market, and Google, such an app does not exist yet. Currently the best app I've found to do anything remotely like this is the Airplane Mode Wi-Fi app, which is a manual switch and a slightly cumbersome one at that, not nearly good enough for how often I go in and out of wifi.
The reason I ask for this is because I use Google Voice with SIP and a prepaid plan. I want to use SIP as much as possible to save my prepaid minutes for when I really need them. When wifi and cell are both connected with Sipdroid running and I receive a call, they both ring at the same time. To be sure I don't accidentally use prepaid, I usually reject the call and call back over SIP, which is slightly annoying for both me and the caller.

I would like to have the cell network type displayed while I am connected to WiFi in the status bar signal cluster. Currently, once you connect to WiFi, the LTE, H, E, etc, go away; I'd like them to stay.
I can move the WiFi icon over to make room for the type icon (LTE, H, E, etc) just by deleting "android:layout_marginRight="-6.0dip"" at the end of the "id/wifi_combo" line in res/layout/signal_cluster_view.xml in SystemUI.apk.
Where is the function that turns off that cell type icon when WiFi is connected in SystemUI.apk? I know the system can detect the type of network whilst WiFi is connected, it's just a matter for forcing that icon to stay displayed.
I am trying this on Cyanogenmod 11.

Is there a widget out there that displays the wifi network the phone is currently connected to?
I did a quick search and nothing came up. I would love something very minimalistic (Name only would be perfect)

Is there a hack to remove the message that pops up whenever my phone connects to my wifi network? I have the phone set to disconnect wifi when the screen goes off, so I always get the "Connected to wifi network xxxxxx" message when I wake my phone.
I know that there is a hack to remove the "Wifi Network Is Available" message but that is not what I am asking here.

I have a Galaxy S3 on the Bell Mobile network in Canada, and aside from the horrendous battery life, it's a pretty good phone. One thing I notice that's kinda annoying is the "Connected to Wi-Fi network [network name]" pop-up that comes up quite often. I've managed to snap a screenshot of it.
How to disable this? The only info I've found so far is on the Verizon pop-ups, and entering the *#6335623# code on the dial screen, but nothing comes up when I try that, and I'm not even sure that fix would work for this.

My HTC EVO 4G LTE is having a major problem. When connected to my home modem it will not connect to the internet at all. When I disconnect wifi in the settings the phone will crawl along at Sprint 3G speeds. Laptops, tvs, chromecast and Roku are all working properly from the same modem. I've reset the modem, restarted the phone numerous times, just updated the phone (was happening before and after the update) and still no luck. I've scoured the internet looking for answers but nothing so far.

I have an LG Optimus Elite and when I first set the phone up with WIFI, the bars were green and everything worked, but then I powered the phone off and the bars turned white and my WIFI status says that I'm connected but nothing (except the browser, Skype and sometimes Youtube) works--they all mostly say "authentication required" or "not connected." I have multiple laptops, have had two iPod Touch devices, and friends' devices work just fine on my internet, but this one won't--the time/date isn't even correct.
I've rebooted the phone about 4 times and each doing different things, like signing in to Youtube with Google account, syncing my Google account, and just trying different things with the WIFI (airplane mode, turning off sleep), and I've restarted my modem and router. I logged in at a restaurant and the time was correct, but I wasn't able to check more than that. I've been searching for a fix for a few days now and nothing has worked at home.
I don't have the phone plan connected so there's nothing that I can do with the 3G connection. It's just really frustrating because I bought two of these phones (one for myself, and one for my girlfriend) and only one phone works, even though we've checked to see if all our settings were exactly the same--which they are.
Edit: Each time I power the phone off the WIFI bars turn white and the internet doesn't work good (like I wrote above). For the amount of time that there is internet (after factory reset) the time is wrong. I forgot to mention this.
Edit 2: I cleared the Google Services Framework data and, after doing that, the WIFI works until I power the phone off and on again. I'll add more information as I try more things.

I have an Asus Slider Sl101. Around 3 days ago, our router had been changes as the previous one wasn't working properly. Our carrier is Charter and our router is Netgear. We hooked every device up to that new router and everything worked fine, including the tablet. But later on in the day,the Internet on there stopped working.
It shows that it's connected, but when I try to access the internet through the browser, it does not work. The blue line at the top of the browser starts up, moves forward a little, and stops entirely while the browser then says "Webpage Not Available". Apps that require Internet, such as Accuweather and my SAT apps, fail to work as well. Other devices that use our wifi include another computer and Nintendo DSi and 3DS. They all work fine. Our router shows that our android is connected to it, as well.
I've tried the static IP stuff, restarted the router, left the wifi off on the tablet for a few hours, and turned it off and off. I even factory resetted it and not even that worked.

I'm wondering if on an android device there's a way to force it to keep open a wifi connection that is not used for data, for example to a Seagate Goflex Satellite (WiFi HDD) or eye-fi (WiFi SDHC) while also being simultaneously connected to 3G for data. Obviously connecting to 2 wifi connections is out of the question.

Downloaded FoxFi, and love it. Great when I need to use my laptop. But...
Lately, I've noticed it has been having connection issues. I start the hotspot, my laptop "sees" it. And I can connect (shows "connected" in the wifi window next to "FoxFi" on laptop). But, at the top of the same wifi window, it also shows (under "Currently connected to:"), "No internet access" (or something - connected right now on different wifi network, so I can't get the exact wording). But I hope this is clear.
Why this weird contradiction? One part of the window says I'm connected, the other says I'm not.

I don't want my user to even try downloading something unless they have WiFi connected. However I can only seem to be able to tell if WiFi is enabled, but they could still have a 3G connection.
android.net.wifi.WifiManager m = (WifiManager) getSystemService(WIFI_SERVICE);
android.net.wifi.SupplicantState s = m.getConnectionInfo().getSupplicantState();
NetworkInfo.DetailedState state = WifiInfo.getDetailedStateOf(s);
if( state != NetworkInfo.DetailedState.CONNECTED ){
return false;
}
However the state is not what I would expect, even though WiFi is connected I am getting OBTAINING_IPADDR as the state.

I send files to FTP server in my application. Internet permission is set :
<uses-permission android:name="android.permission.INTERNET"/>
It works quite fine when connected with 3G/3G+. Sometimes, not very often, I get a "SocketException no route to host" or "unknown host" exception when trying to connect. When I'm connected with WIFI, it works sometimes and it's very fast, but the same error occurs very often, and when it has occurred I must restart my WiFi to be able to connect again, even with webbrowser. I use apache commons FTPClient this way:
ftpClient.connect(server, 21); ftpClient.login(user, password);
ftpClient.changeWorkingDirectory(directory); ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
BufferedInputStream buffIn = new BufferedInputStream(new FileInputStream(file));
ftpClient.enterLocalPassiveMode(); ftpClient.storeFile(file.getName(), buffIn); buffIn.close();
ftpClient.logout(); ftpClient.disconnect();
Errors look like this:
06-12 11:17:32.887: ERROR/DictoSyl(3146): No route to host 06-12 11:17:32.887:

It looks like having forgot something that makes connection down after several uses of my ftp program, but what? And why does this work quite well (but not always) with 3G/EDGE connection?
