Time to put it on some memory stick and ask for help from others while you wait for your support to kick in.
Forget the network that doesn't work and try other hot spots.
I'm a college student with a dilemma: I have to upload an assignment (the library is closed) but I can't connect to the internet. Ethernet doesn't work either. I know that this is not a problem with the network because I live at school and it would be chaos if the Internet went down, and I'm able to post this question with my Kindle, which connects no problem. I have tried every fix I can find including: renewing dhcp license, deleting and reentering connection, and plugging into ethernet, and running diagnostics, which tells me my ISP has failed. None of my programs can connect. Firefox says "server not found" and safari just won't load anything. I'm getting desperate. Any suggestions? Thanks in advance. I use a MacBook Pro (13-inch Early 2011), Mac OS X (10.7.3)
