I am working on a capstone project for school, what i need is to be able to take WiFi scans (no need to connect, only scan available network BSSID and signal Levels) quickly.
Currently, the Android API takes up to 5 seconds for a scan. Is there something i can do to improve my scan rate?

I have two android devices at home, a HTC One S and a Nexus 7(2012). The problem is that when I am using one or another occasionally the wi-fi will simply stop working. I'm still getting full signal in the notification bar, but either Chrome or whatever app that is using the wi-fi will stop retrieving data and eventually time-out or stay on buffering.
I have tried some things including changing the channel my wi-fi is set to from Auto to 6 and Mixed B/N/G mode to N only, but nothing seems to fix this problem except for one thing; turning the wi-fi off on one of these devices. The connections seem perfectly stable when I do this.
I also have a laptop in the house, my girlfriend comes over with her iphone, and I have an ipad from work that I occasionally bring home (I'm a teacher) and none of these devices ever have any issues, it's only the two android devices.
It's almost as it they are sharing the same wi-fi train track and only one can ride it at a time.
I am trying out this code for scanning wifi networks but getting null pointer exception not sure what problem I registered all permission in manifest.
IntentFilter i = new IntentFilter();
i.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
registerReceiver(new BroadcastReceiver(){
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Log.i(TAG, "opening wifimanager");
WifiManager mWifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
mWifiManager.getScanResults();
} } ,i);
mWifiManager.startScan();
wrong area for this but i have a alcatel one touch 960C (not even on this site) but i cant connect to wifi at ALL. its stuck on scanning and it flashs scanning sometimes. any way to access wifi files or some sort?
ive tried everything.

sysetem restoring
SDK (not sure if any wifi sdk's are out there)
i dont have data so i have no way but PC to access files.
how to flash nor do i now anything on roms or flashing roms.
I have a samsung galaxy n7000, the wifi & bluetooth aren't working nor scanning. i've tried factory reset but nothing. or a download link for jelly bean 4.1.2 XXLT5 to reflash it.
View 2 Replies View RelatedI'm trying to enable the active scanning mode on my HTC Desire but still got no luck. I've forced Android and wpa supplicant to go in to active mode. I've retraced this and the forcing works but when wpa supplicant tries to set the driver in active mode it always got set in passive mode and I can't force it in to active mode.
Any way to force an android device to scan active for wifi networks? It doesn't mind if It's on another device. I'm desperate to get it to work.
And I know it's not power efficient but that's not the goal. The only goal is to scan as fast as possible. Scanning in active mode should make this possible.
Is this even possible? Does an app have the ability to increase wifi signal and get 40-50% faster internet ?

Is it generally possible to have Wifi Tethering turned on (creating a Hotspot) and at the same time scanning for Wifi devices? I want several devices just discover (NOT connect) each other and log the signal strength. To do that all devices must be discoverable over Wifi and at the same time discover others.
I would just need that for some specific use case..
Recently I bought a wifi range extender (TP-Link tl-wa730re first version) and I configured it in order to extend (range extender mode) wifi signal of my router over some rooms of my house. In particular I use this extender to take the signal into a room in which I already get router signal, but it's too low to have a fast connection.
So in this room I have 2 signal (I used this app to analyze my conditions Play Store Link): the router one, with 20-30%, and the repeater one, with 70 %. I haven't any problem with my pc, but I have the same issue with my android devices (galaxy nexus, 2 nexus 7, htc sensation, xperia u): they randomly disconnect themselves for just a couple of seconds and then they switch between the 2 signals
Moreover about every 10 hours, I must reboot the extender, or every android device stops to get a working connection. For example, my gnex lost connection and continuously tries to connect to router, but it always fail.
If I move from this room to another one (especially if in this room router signal is stronger than before) my devices lost connection and I have to reboot phone or tab to get connection back...
My router has a WPA-PSK TKIP-AES password, dhcp enabled, automatic channel search enabled (the usual channel is always free), and wifi bg with a speed up to 125 mbps. My extender has no password configured, dhcp disabled, same channel of router and its extended wifi has been seen by every android as the same of router (only 1 signal is detected into settings).
I already tried to set a static IP from wifi settings on phones but nothing change..
My main device is an HTC One M8, but I also have a Nexus 7 2013, Nexus 7 2012, Galaxy Nexus, and a Moto X running on the same Wi-Fi network. They are all experiencing some slow activity on Wi-Fi. I also have 2 desktop PCs and a Laptop running on the same network and they are running fine, no noticeable lag.
On all of my Android devices, browsing the web via Chrome is almost as snappy (but still not the speeds I get on data) as it is on my computers. However when it comes to certain apps, there is a noticeable slowdown. Instagram has a lot of trouble loading images, Facebook, Twitter, Play Store downloads are stupid slow as well. And a bunch of push notifications from those apps, as well as GMail, won't come through or will come through hours after they should have.
But if I just switch Wi-Fi off on the devices that also have a data plan running (Moto X, One M8, GNex) everything comes through as fast as expected.
Could it be my router? I have a Linksys E800.
Best software for streaming audio/video from android to android, this question is 2 fold.
1 I would like to use my old POS zte racer android device with a restive screen and 3.2 mpxl camera as a video monitor in my babies room, over WiFi.
2 I would like to duct tape an old android device to the front of my RC monster truck and drive it through an apple store on fire. Over 3G or perhaps WiFi hotspot from my good phone, shared with the duct taped bumper droid.
What is a good app to connect two devices using wifi without a router? Just to share pics, vids, and files. I have a Bionic (4.1.2) and a Polaroid PMID705X (4.0.4, wifi only) tablet I'm wanting to do this with

Recently my finace and I both noticed that when our phones are on WiFi instead of 3G/4G we can't get apps to download, we also noticed this happening on the Xoom which is really a problem since we don't have any mobile service on that. Nothing changed in our WiFi configuration between when it was working properly and now. And all devices did it at the same time. what may be affecting the devices to cause this to happen.

View 1 Replies View RelatedI used to get my battery to last from 8am to about 10pm at night with it in the red zone. Recently though I have been working more from home and now have an airave and connect to the wifi network. Now all of a sudden when I go to bed I'm over half maybe even 3/4 of the battery is left.
My thinking is some of the battery drain may be caused by poor reception. For those of you with battery issues or issues on some days and not others, look at how much reception your getting in addition to use and radios and all that. Maybe the problem is sprints network.
Note 10.1 (N8020).
Allshare video playback from other devices over wifi just stopped working. It was totally fine and I have absolutely no idea what happened. It still plays music and shows photos and all the files stored on external devices. The only problem is that it won't play video. It plays video stored locally or on sd card just fine, but when I want to play anything from my note 2 (n7105) or my pc's allshare app, video player shows error message: "Cannot play video. This video cannot be played".
It plays the same files just fine, when I copy them to the device, so I think it might be the case of some transcoding error. It is not a case of network settings - I've checked on 4 different wifi networks and it's the same everywhere. My note 2 works just fine on any wifi and plays all video from tablet or pc. Here is what I tried so far, with no results:
1. Restoring to factory defaults,
2. Wiping cache and dalvik cache,
3. Flashing fresh stock rom,
4. Erasing all allshare apps and video player data

My network is with a password, and i entered it correctly, i checked twice before typing the pass...

I dont have any other wifi connections in my range so i cant check for another wifi connection.
I have the Galaxy S3 mini. I keep getting the notification to "Sign into Wi-Fi network"..Sometimes my phone is connected to wifi and other times it is on 4G.
I know this is a phone issue and not a network issue because it happens to me when I am at home and at work, I connect the the wireless router in both places.
I select it and it brings me to the web.how to stop getting this notification.
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 have installed android 2.3.7 rom on my karbonnA1 same as that of ZTE N721.. with some modification to ZTE RACER rom.. i was able to boot the rom ... but the issue is WIFI, Bluetooth, and network is not working? Do I have to modify the kernel.
View 5 Replies View RelatedI 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.
I'm wondering of there's some app that automatically connects to any open WiFi network.

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.
You can use the 3G network for surfing the Internet and at the same time the wifi network to move files only?

I have an android application using LocationManager get the cell network location and not the Wifi location? If I have turned off the Wifi antenna and do the following:LocationManager lm = (LocationManager) paramContext.getSystemService(Context.LOCATION_SERVICE);I am always returned the Wifi location and not the cell network location. I want it to return the cell location since I have moved fromthe Wifi location. I tried using a LocationListener but that doesn't seem to help.
