blocks|key|1077447|text|由于这似乎是一个流行的问题，我将继续添加一个更新的答案。SDK仍然不支持WiFi仿真，但是基因运动默认使用WiFi，所以您可以使用它来开发/测试具有特定WiFi功能的应用程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1077448|entityMap|0|LINK|mutability|MUTABLE|url|https://www.genymotion.com/^0|19|4|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Since this seems to be a popular question, I'll go ahead and add an updated answer. The SDK still doesn't support WiFi emulation, but <a href="https://www.genymotion.com/" rel="noreferrer">Genymotion</a> does WiFi by default, so you can use that to develop/test apps with specific WiFi functionality.

Currently, while you can use your computer's Internet connection in the emulator, it's not reliable to use it for simulating Wi-Fi. The <a href="http://developer.android.com/reference/android/net/wifi/WifiManager.html" rel="noreferrer"><code>WifiManager</code></a> gets confused when you switch/want to test your connectivity state.

Even in Android 1.5, there were some problems with it (<a href="http://code.google.com/p/android/issues/detail?id=2571" rel="noreferrer">Issue 2571 - android</a>), and while you can use your Internet for simulating HTTP connections and downloading data, finer control over Wi-Fi connectivity should better be done with a device.

Starting from revision 26.1.3, the Android emulator now supports connecting to WiFi on a Nougat image (API 25).

<blockquote>
 Added support for Wi-Fi in some system images (currently only API level 25). An access point called "AndroidWifi" is available and Android automatically connects to it.

You can check the version of your emulator by going into emulator settings (three dots) > Help > About. Also note that if an AVD was created before version 26.1.3 was released, you will have to recreate your AVD. I read somewhere that wiping data might also work, but I did not try that.

blocks|key|2602374|text|如果您没有真正的设备，我认为最好的方法是安装安卓-x86或在现场usb上使用它。android和android-x86之间没有区别。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2602375|而Androidx86支持wi。所以你可以安装你的应用程序，并运行它。|2602376|entityMap|0|LINK|mutability|MUTABLE|url|http://www.android-x86.org/^0|M|6|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

If you don't have a real device, I think the best way is installing <a href="http://www.android-x86.org/" rel="nofollow">android-x86</a> or use it on live usb. There is no diffrences between android and android-x86. 

And android-x86 support wi-fi. so you can install your app, and run it.

blocks|key|1077374|text|理论上，linux+(安卓的底层内核)有hwsim驱动程序，它模拟WiFi。它可以用来设置几个WiFi设备(一个访问点，另一个WiFi设备等等)，这将构成一个WiFi网络。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1077375|它对于在linux下测试WiFi程序很有用。可能，甚至在用户模式linux或其他与linux隔离的虚拟“盒子”下也是如此。|1077376|理论上，这个驱动程序可以用于在没有真正的WiFi设备(或者不想使用它)的安卓系统中进行测试，也可以在某种安卓模拟器中使用。也许，我们可以在android-x86中使用这个驱动程序，或者--用于测试--在Androidx86中运行在VirtualBox中。|1077377|entityMap|0|LINK|mutability|MUTABLE|url|http://linuxwireless.org/en/users/Drivers/mac80211_hwsim|1|http://en.wikipedia.org/wiki/User-mode_Linux^0|K|5|0|0|S|9|1|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@$A|S|B|T|1|U]]|C|$]]|$1|D|3|E|5|6|7|V|8|@]|9|@$A|W|B|X|1|Y]]|C|$]]|$1|F|3|G|5|6|7|Z|8|@]|9|@]|C|$]]|$1|H|3|-4|5|6|7|10|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]|P|$5|K|L|M|C|$N|Q]]]]

In theory, linux (the kernel underlying android) has <a href="http://linuxwireless.org/en/users/Drivers/mac80211_hwsim" rel="nofollow">mac80211_hwsim</a> driver, which simulates WiFi. It can be used to set up several WiFi devices (an acces point, and another WiFi device, and so on), which would make up a WiFi network.

It's useful for testing WiFi programs under linux. Possibly, even under <a href="http://en.wikipedia.org/wiki/User-mode_Linux" rel="nofollow">user-mode linux</a> or other isolated virtual "boxes" with linux. 

In theory, this driver could be used for tests in the android systems where you don't have a real WiFi device (or don't want to use it), and also in some kind of android emulators. Perhaps, one can manage to use this driver in android-x86, or--for testing--in android-x86 run in VirtualBox.

Probably no substitute for testing on a real device, but if you're looking for a good enough test case in the emulator give <a href="http://forum.xda-developers.com/xposed/modules/app-fake-wifi-connection-t2800416" rel="nofollow">Fake Wifi Connection</a> a try: 

It makes apps think they're on wifi no matter what the underlying connection is.

disclaimer: I wrote this stuff. 
It works by intercepting ConnectivityManager / WifiManager calls (uses <a href="http://repo.xposed.info/module/de.robv.android.xposed.installer" rel="nofollow">Xposed</a>). I've tried to cover most of them so it does a pretty good job, nevertheless it's always possible some is missing (if you find something let me know).

I would like to check from my app whether the device has WiFi connectivity, but in order to do that, I must first find a way to get "WiFi" in the emulator. Just going to Settings -> Wireless controls -> Wifi says Unable to start Wi-Fi, while <code>logcat</code> says:

<pre><code>E/WifiService( 566): Failed to load Wi-Fi driver.
D/SettingsWifiEnabler( 695): Received wifi state changed from Unknown to Enabling
D/SettingsWifiEnabler( 695): Received wifi state changed from Enabling to Unknown
</code></pre>

How can I simulate WiFi connectivity in the emulator?
