I started having a problem with my sprint 3G aircard about two months ago getting into one specific website (Shutterfly.com) to view pictures of my grandchildren. I have no problems getting into this site using local WiFi networks, but cannot get in using my aircard. Any ideas on what I might do to fix this? I had no problems until a couple months ago. I don't think I changed any settings on my air card but due to my lack of in-depth knowledge of computer technology, anything is possible. Help, please!!
