I've done tons of research all over the internet looking for a way to do internet sharing, through a wireless connection (if it's even possible) from my PC at home to my Macbook Pro. I've come across plenty of tutorials on youtube and elsewhere describing how to do internet sharing the other way around, from a Macbook to a PC, but I'm trying the opposite. So the deal is, I have a roommate who owns his own PC, and is in charge of paying the monthly internet bill. He pays for that and I pay for the phone, and we split the cable. Anyways, due to a recent argument he's decided to log onto the router, change the passwords to get into it, and change the WPA password to the internet connection. So now I have no connection at home, unless he's not here (I secretly know the password to get onto his PC, that's what I'm using right now) and I'd really like to be able to somehow share the internet with my Macbook so that I can connect without him even knowing, through a wireless connection. I've figured out how to share the connection through an ethernet cable, but again, I'd like to find a way to connect while he's at home and not knowing, (unless he happens to go into control panel and see that the "Share connection with other computers" is checked, which I'm absolutely positive he won't. I've tried tons of tutorials and nothing's worked over wireless, I've heard it can be done but sometimes when I mess with the network connections I end up accidentally ruining the overall connection to the internet and then I can't even connect through the PC until I undo what I did. I know it has something to do with the DHCP and manually entering the ICP into the network connections on the Mac, but I'm not sure. So can anyone help me with a thread, video, tutorial or ANY type of explanation on how to share from my roommate's PC with Windows XP to my Macbook Pro? Even if me connecting to the internet is only possible while his computer is on (he leaves it on a lot) I'd absolutely love not worrying about coming into his room and connecting my laptop through an ethernet cable to get internet on my Macbook. PLEASE HELP!!!
