I'm having the same no internet upon start issue that many others are having with their i7. I had another problem today that was frustrating. I was using my SP3 during a class lecture and went to play a Youtube video. 15 seconds into the video my Internet dropped and wifi reported no Internet connection. I had to go find the wifi icon in the system tray and run troubleshooting to have it reset my connection. Took 2-3 minutes. Very frustrating and disruptive to the overall class flow. (Definitely just an SP3 issue as other devices in use weren't affected.)
