I have a laptop as a file server using Win 2008 Server connected via ethernet to a Cisco EA4500 router to provide internet and media access to all my devices including a Macbook Pro. Our ISP has a 2km WiFi hotspot we all access. There are bi-directional antennas everywhere. I'm sharing 150,000 files via the server via wireless using the internal WiFi card. The problem: Only the ppl near me can access the files on my server, and I can't figure out why. I have posted this on another forum and the response was... We don't deal with issues this basic. I have tried googling different phrases on this, but no bueno thus far.
