Hello everyone, So I used to connect my iPod Touch and siblings' windows dell laptop to my macbook pro through internet sharing so that we could use internet wirelessly. this is primarily because we do not have a wireless router. but recently I noticed that I can not do this. The only thing I know of that is different about my mac is that I updated everything on the software updates and changed my desktop background recently. I have tried everything I know but am lost as to what could be the problem. I am currently on a Macbook Pro 2007 model with 10.5.6 Leopard. Has anyone else experienced this problem as well?
