You can use the async methods of the NetworkStream and set a ManualResetEvent in the EndReceive method.

// ...
netStream.BeginRead(buffer, offset, callback, state);
// ...

inside the callback method

netStream.EndRead(ar);
netStreamManualResetEvent.Set();

then your code

while (notDone)
{
    WaitHandle.WaitAny(new WaitHandle[] { queue1.HasData, queue2.HasData, netStreamManualResetEvent} );
    // ...
    if (netStream.DataAvailable)
    {
        // make the buffer from the AsyncState in the callback method available here
        // process buffer
    }
}
