此处是有一个安全的WiFi连接 - 我不知道的密码 - 但有一个设备 - Galaxy Nexus智能手机已经连接到该WiFi和我的Galaxy Tab平板电脑。 将GN设置为蓝牙调制解调器，为TETHER WIFI连接，对于GALAXY TAB，有任何更改为TETHER WIFI连接？
Here is the point there is a secured WiFi connection - which password I don't know - but there is an device - Galaxy Nexus smartphone which is already connected to that WiFi and my Galaxy Tab tablet. There is any change to set GN as Bluetooth modem, to tether WiFi connection, for Galaxy Tab?
Android 4.0+ officially supports bluetooth tethering in both directions (and allows bridging to whatever the internet connection is (wifi/usb/3G)).
You then can connect to the tethering profile:
settings => bluetooth => paired devices/GN => profiles/Internet Access
The GNexus fulfills all of that, however your P1000 cannot officially upgraded to Android 4.0 though, so you're out of luck or you have to install an aftermarket firmware (e.g. CyanogenMod9, which is based on Android 4.0.4)
