Reconfiguring your network can cause issues with using campus websites
Whenever you come on campus, or connect to any network, your computer first asks for some basic information. This includes information about DNS (Domain Name Service), which allows your computer to know where csumb.edu is, or how to connect to google.com. Manually configuring your computer to ignore these commands can cause problems using campus websites.
If you are having problems when you come on campus using sites like MyCSUMB or CSUMB.EDU, it could be because you have overridden your network settings. This typically only happens on Mac OSX machines, since these settings apply to all network connections. To fix the problem, go to your System Settings, and click Network. Click the Advanced button, then the DNS tab. All the DNS servers on the left should be grey. If they are black, select them and click the minus button below.
