Android模拟器有时不能连接到互联网

我有Ubuntu Linux操作系统的10.04，我collegue使用SUSE。我们有Wi-Fi连接到互联网。我们使用Android模拟器有几个虚拟设备。我们有问题与虚拟设备的因特网连接。通常它工作得很好，但有时（约25％），虚拟设备没有显示出GSM信号，即使PC机连接没有互联网。有这种行为没有明确的原因。它会留下永远断开，所以如果它发生，我们将不得不重新启动虚拟设备，并希望下一次尝试都会好的。有时会发生于所有Android版本的虚拟设备，但它是在Android 2.x的比Android 1.x中更常见是否有人有相同的错误？

I have ubuntu Linux 10.04, my collegue uses suse. We have Wi-Fi connection to the Internet. We use Android emulator with several virtual devices. We have problem with the Internet connection of the virtual devices. Normally it works well but sometimes (about 25%) the virtual device shows no GSM signal and no Internet even if the PC is connected. There is no clear reason of that behaviour. It will stay disconnected forever so if it happens, we will have to restart the virtual device and hope that the next attempt will be OK. It happens sometimes to all Android version virtual device but it is more common on Android 2.x than Android 1.x. Does anybody have the same error?
