After trying to do a wget to my host, I realize you are correct. I cannot do any wget's from my Edison. However, I just did some test wget's from two other Linux computers on my same home network OK, so I don't see how it can be my firewall.
Any other ideas? I do have my Edison configured for a static IP, but so was one of the other Linux computers I just tested OK.
Or should I take this issue over to the Makers/Edison forum now that I know it's not a Developer Zone issue?
