We have an iPad 2 of which is working very well. When I am away in either Spain or Barbados or at my home in Epping I get no problem with Safari responding, but when I am at work I connect into my works WiFi system where I can pick up my company e-mails. The issue that I have is Safari sometimes does not respond and gives the message "Safari could not open the required site as the server is not responding" WiFi signal is no issue. What I have to do is turn off the iPad the re-turn on again and it works. Does anybody know if it is an operating system problem or could it just be the area I am in.
