I need to find a solution ti the issue of only having wired access in places. I understand I can get an Airport Express to basically create a "personal hotspot". Questions: 1). I know I need a PC (don't own Macs) to set it up. Once set up do I have to take my pc everywhere to reconfigure it at each location? Or is this just the initial setup? 2) Are there any specific setup instructions specifically for the iPad? I need to do this for my husband who is in Iraq and only has a netbook and iPad with him. The netbook doesn't have a built-in optical drive. Now I can also send him the external drive I have but his IT technical expertise is not the best ( this from a guy with 3 engineering degrees). This has always been my job so if I can set it up here, send it to him and all he has to do is plug it in and go it will save me from having to give instructions and trouble shooting via an international phone call. Any help, insights, and tips are greatly appreciated.
