I took my personal Macbook to work to have my boss set it up so I could connect to the company's VPN and server. While at the office I connected to random unprotected wireless router. We tested it at the office and my computer connected just fine and I had access to the company server. Then I went home and tried to get on the VPN via my wireless router and I get this message: "You have been disconnected by your communication device. Check your settings and try again." My first inclination was something was wrong with the router settings. I checked the settings and all VPN/encrypted tunnels were ENABLED. I tried changing them to disable and back again, but that did nothing. Then I read a message board that said sometimes it will work if you a plugged into the router. I did that and to no avail. I brought my macbook back to work, connected through the same random unprotected router and , of course, it worked great. So Clearly, there must be a problem with my router/ISP? I am not very good with computers when it comes to networking. Does any one have any ideas as to what the problem could be? Thanks.
