android 2.2 emulator -- Fails to load Wi-Fi driver - android-emulator

I can't connect my emulator -- Target: Android 2.2 -- to connect to my home wifi that I know works ok. (Had also been able to do that a couple of months ago.) The emulator displays "(No Service)" on top right of start screen. LogCat shows:
10-26 05:53:16.531: INFO/WifiService(60): WifiService starting up with Wi-Fi disabled
...
10-26 05:57:44.963: ERROR/WifiService(60): Failed to load Wi-Fi driver.
Have tried running Dev Tools > Connectivity > Enable Wifi, but only see another "Failed to load Wi-Fi driver entry in LogCat.
But emulator -- Target: GoogleAPIs on Platform 2.1-update1 -- displays "Android" on top right, and seems to connect to the same home wifi fine. Eclipse and emulator run on my Windows XP laptop.
Appreciate any insights...

The emulator will do networking, but the wifi doesn't load a driver due to not being able to access the host hardware.
You need to test wifi code natively.

I also encounter such problem when trying to perform WiFi scanning from the emulator. However when i tried running the program on my physical device, no such problem encountered.

Internet is not connected in Android Emulator, when net is taken via mobile through hot spot

I am working in a native-script application, so I use Android Emulator for checking, I have mentioned below the version of Emulator.
The Internet is not connected in my emulator even signal of the WIFI also shows cross mark whenever I connect the internet connection from my mobile (Android Lenovo P2) through hot-spot.
The emphasized textInternet does connect in my Emulator whenever I connect internet via my ACT connection wifi through the router.
Emulator APK version: 26.
Emulator device: Nexus 5.
Note: My laptop connects the internet only problem in Emulator
Does anybody help me To do any setting has to be done in my Emulator to connect the internet when I connect through my mobile hot-spot?
This clearly indicates Android emulator doesn't recognize youe mobile network connected with your machine network configuration. I would recommend to try following actions to resolve this issue.
Open the AVD Manager and wipe the data of that emulator.
If you were working with wifi network and instantly switch with your mobile data may cause this problem. just try to restart the emulator and try.
Your Emulator may be pointed with older version of SDK, so you may want to uninstall Android Emulator and re-install it. Sometimes older SDK data causes the issue that you have encountered.
Reboot your machine then connect freshly with your mobile data started with emulator and check it out.
If above nothing works just uninstall AVD and re-install.
Look out this Reference link as well.
Please let me know the above solutions works for you! Cheers!!!
I have fixed the issue by adding this line in Androidmanifest.xml
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

How to prevent run app on windows emulator? I want to run app on real device that conected to my computer.
I am using windows 8 and Huawei with Android 4.2.2
::note
I have read these questions, But I didn't got the answer!
Why not work Ionic app testing on android real device?
Ionic run android does not run app on device
ionic run android - configurations not running app on device
As a complement to #OClyde answer, you could try :
adb kill-server
adb start-server
To have infos about these commands :
adb --help
Nb : Sometimes, for a reason i do not know, the connection between my phone and the computer break. Running this fixes it.
To make sure that your app is not installed to an emulator but to your device, take the following steps:
Open up your console and run adb devices. This should give you a list of all devices available (real devices as well as running emulators) to the Android Debug Bridge. If the adb command is not recognized check that you have installed the Android SDK correctly and that you've set all the necessary environment variables accordingly.
The adb devices command might give you output similar to this:
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
This indicates that the ADB wasn't ready before, so in this case just try to un- and replug your device and run adb devices again to see if the device is listed afterwards.
If your device is still not showing, check that USB Debugging is enabled on your device. Therefore you first have to enable developer settings, which you can do by tapping the build number (Settings => About Phone) 7 times (no, that's not a joke ;) ). After that, you'll have the developer options in your settings menu. Open these and check "USB Debugging"
If still your device isn't recognized by the ADB, change the USB connection mode. You can either do this in the developer options as well or tap the notification shown when the phone is connected to your PC. Try MTP as well as PTP, on of those should do the job.
After these steps, it should be nearly impossible that the device is still not recognized by your PC. As soon as there is a phone available, Ionic will install the app on the phone automatically instead of launching an emulator.

Android 2.1 Superpad Tablet: can't connect Eclipse ADB to Superpad USB port

I am developing an Android app for a class I'm taking. I've been using the emulator to date. I know what to see if it runs on the real HW.
My PC runs Windows 7. I downloaded the latest google/Android USb driver. I have enabled the USB Debugging feature on the tablet already. When I plug the tablet into the PC via USB, the PC doesn't seem to see the tablet at all.
What do I need to do to get these two devices to see one another.
thanks,
wk
HI, I'm using superpad 3, and just have adb connection over ethernet, all you need is type cmd: "connect your.pad.ip" and then Eclipse will see your device.

Android Emulator 'No Service'

I am new to both the android and android development so I'm not on familiar ground here.
When I start the emulator I have no service. Therefore I have no internet connection on the emulator.
I am running Windows 7 and I generally run the emulator via eclipse.
My host machine is connected to the internet via the Local Area Network. There is no proxy.
I have tried:
Disabling all network adapters except for the Local Area Network [link]
Running the emulator from cmd line with: emulator -avd -dns-server 8.8.8.8
Reinstalling the SDK Tools 9 and Platform Tools (rev 2).
Restarting the machine! :P
Is there a setup needed to specify to simulate a 3G connection? Or could this be a Windows 7 permissions issue? Or am I doomed like these folks: link link
Ah! found the solution.. I uninstalled the entire SDK and reinstalled it to C:/Android. I deleted the C:/Users/[your-name]/.android folder and recreated an avd. Voila.. Something in there worked!
[edit]
Actually it looks like you have to keep restarting the emulator until it connects. I will often get no service so I restart a bunch of times till it works.
I found that 'Airplane Mode' was enabled by default in the standalone android emulator - this may also be the cause in the sdk version. Turning this off (by holding down the red power button until the menu came up, and then toggling the airplane mode button/section) allowed the emulator to 'find service' and connect properly through the LAN.
