Hi. I don't think I've got anything blocked as far as a firewall goes. I've tried connecting to squarespace.com and ehow.com and it won't connect. Other sites work fine. I tried my neighbor's W-LAN and I couldn't connect either but he connected to squarespace on his macbook pro, so I think it's something with my computer and not my apartment's W-LAN connection. SPECS Mac OSX 10.5.8 Intel Core 2 Duo, 2.4 Ghz. 13" aluminum body, bought about a year ago Tried both Safari and Firefox browsers Any ideas as to what my problem is and how to fix it? Thanks.
