Re: [android-developers] Re: Does a device have Wi-Fi or not?

You could try turning it on with WifiManager.setWifiEnabled, and check
the return value. With appropriate UI it might not be so bad.

Another idea is to check for the presence of low-level WiFi related
files (such as /etc/wifi/wpa_supplicant.conf). This is clearly outside
the boundaries of what a "proper" app is supposed to do, but then
again, if the documented APIs are broken (yet again)...

Yet another idea is to maintain a list of devices that are known to
have WiFi and report is being absent, identifying them by fields found
in android.os.Build . Time consuming, but doable.
