General :: How To Enable Active WiFi Scanning
Apr 18, 2012
I'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.

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?

there is a way to more selectively manage probing requests in android. I am always forgetting to turn off my wifi when I leave the office/home and don't really like the idea of my phone broadcasting so much info about me in the requests (esp when i don't need wifi). I have been looking for settings but didn't find one and was thinking about an app perhaps that maybe can turn wifi off based on location (though i guess that would need gps which would be another issue?). I would settle for something that turns off wifi once it is out of range of a certain point (like home or work) for a certain period of time, then i could just turn it on manually when I am say at a cofee shop or whatever (and maybe it could turn off again when that point gets out of range).

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..

Is there an app that lets me automatically turn on wifi when I try to connect to the Internet and after a while not using it to disable it? I really need that because I hate toggling wifi and sometimes my sister doesn't disable it and my battery is drained

I tried Update Driver , it is saying as uptodate... but still the problem exists , i cant connect wifi and also Hosted Network is showing No (while i run a command in cmd prompt)
and one more thing while i used mhotspot also no use it is saying as the group or resource is not in the correct state to perform. enable wifi to my HTC one S android mobile also....

I moved from Galaxy S4 to Galaxy Note 2.
Everytime I take a new phone, during initial setup it gives me to restore my settings from Google which when I enable I get all my saved wifi-access points.
This time however by mistake I didn't allow Google to restore that data in my Note 2 so now I haven't got any saved WiFi passwords.
I had backup of all user and system data from S4 via titanium backup and I tried to restore WiFi access points in Note2 which wont work (maybe compatibility or something, I don't know)
how can i re-enable or force a re-sync that Google to restore my WiFi access points to my mobile or what can i do to get all my saved WiFi profiles back.

I have a Motorola MZ604, wifi only, with Android 4.0.3 from Team EOS XOOM ICS 4.0.3 Wingray MZ604 NIGHTLIES, build 57.
I want to connect it to an Adhoc WiFi port from my mobile phone: Hotspot (Nokia N9), but the XOOM can not find it. But with my laptop, I can connect it very easy.
I listen about, and suggest to install the zip file: wpa_supplicant, at:
[URL]
Probably it works for older version of Android 3, but I tried once, and it did not work, and also I have to reinstall the Nightlies again.Any verified file and way to do it?

This is what I would like to do: => IF WiFi is enabled AND active, launch an intent (in fact it's a WebView that gets its content=>the instructions of my app on the web) => IF NOT, then I would launch another intent so that I don't show a WebView with "Web page not available ... The Web page at http://www.mywebsite.com might be temporarily down or it may have moved ..."
I tought initially to use
if(wifi.isWifiEnabled())
but that does not say if the Wifi connection is ACTIVE or not. It says only that the user has turned the switch on. The device may or may not be connected... Is this correct ?
Then I tried to use :........................

I am currently having an issue with most android devices in my work place where they are unable to authenticate with the exchange once connected over the wifi.
Breakdown:
We have 3 wifi networks.
1. General (Wifi authenticates over the domain)
2. Guest (Open wifi)
3. Mobile (Open wifi)
The below devices that we have tested give us an certification issue once they have connected to either the Guest or Mobile although they do work once connected to the General wifi or 3G/LTE.
Samsung Galaxy S4
Nexus Tabs
Samsung Tabs
All Apple devices work 100%
My Samsung S3 works 100%
Samsungs S4 Version:
Android version: 4.3

Does anyone know if there's an app to automatically change the WIFI state (on/off) based on whether the power is plugged in? I'd like to set mine up to turn on wifi whenever I'm plugged in to a power source.

How do I enable/disable GPS and Wifi providers? I check to see if they are enabled by using this code:
locationManager.isProviderEnabled("gps") locationManager.isProviderEnabled("network")
If both are false, I'd like to turn enable the GPS provider and/or the Network provider so that the above checks would return true. Is this possible? If so, what permissions does it require?

Is there a way to enable or disable tethering (USB or wifi) on an android phone programmatically? Perhaps an API in android SDK or NDK or any even non-UI command to do that.

Do you enable WiFi and then begin tethering or do you just open the tether app? The reason I ask is because I enabled WiFi and then opened the tethering app and my phone froze.

Wouldn't it be cool if I could tell my phone to switch wifi on and switch 3g reception off when it senses that I am at work or home based on my gps coordinates and then reverse that when I'm on the road i.e. not at those coordinates I set. Is there an app that does this?

Can it be done? Obviously Verizon and Motorola have disabled it because they want us to pay $20/month for the Verizon app. Yeah, sure Verizon. Anyways, if it requires a custom ROM to enable, then we're SOL until someone breaks the bootloader encryption or we have to use the free WiFi Tether for Root Users app which only supports Ad-hoc mode and WEP encryption, which basically is the same as no encryption really.
