I used internet connections on my macbook pro laptop and i found that the internet recovery process fails on this laptop. When i recover my internet setting using Singtel or Starhub telecommunication service, it always fails and shows error codes like 3403F or 4403F. I used Mac OS X Lion Internet Restore process and this process, installer CD helps me. I don't know the meaning of this error code but need some valuable suggestions for avoid it. Thanks for nay help.
