Hi, I have a year old white macbook. Everytime I wake the machine up from sleep and try to use the internet, I have to run Network Diagnostic first, otherwise it won't let me access the internet. The icon in the toolbar says that I have a connection, but when I go to system preferences, it says its connected, but that there is a self-assigned IP address. When I run network diagnostics, it asks for my WEP passkey (that it already knows and has been saved to my keychain) and then connects to the internet with no problem. Is there a way I could just keep my laptop connected to the internet even after waking up? Any help that anyone could provide would be greatly appreciated.
