I'm trying to share my internet connection from my Macbook to my PS3/Xbox, but for the life of me I can't get it to work. My wifi connection is from my university - I'm living in a dorm, so I have no access to the router or anything. I've tried a million different settings, and I've Googled and Googled so I'm not a newb. I go to Preferences / Sharing, and do the sharing thing - wifi to ethernet. I've tried using DCHP, DCHP with manual address, manual - nothing. The settings I have at the moment are: Mac: DCHP with manual address 10.0.0.10 and on my PS3: IP: 10.0.0.20 Subnet: 255.255.255.0 Gateway: 10.0.0.10 DNS1: 18.104.22.168 DNS2; 22.214.171.124 i keep getting DNS errors. I've tired using different DNS' - OpenDNS, the Mac's IP address - but nothing. I can't figure it out. I've tried everything I can find. Has anyone got any help at all? I'll be eternally grateful.
