While most students like to gripe about how slow the Wi-Fi is, the computer/Internet situation on campus is actually pretty good. If you're working (or, ahem, watching "Buffy" on Netflix) and need a fast Internet connection, you have the option to plug in with an Ethernet cable, which usually speeds things up quite a bit. The network also extends pretty much everywhere on campus, so you can surf the net while outside, in your friend's dorm, or even on the roof of a building. If laptops aren't your jive, there are also really nice computers available in Usdan, Exley, Allbritton, and Olin.
What they're all complaining about, though, is the fact that the administration promised students better Wi-Fi, and although it's changed, the consensus is that it is not that much faster—if at all. That's a bummer, and it's also inconvenient that you have to re-sign in every time you close your computer or lock your iPhone—but all things considered, these are small problems. If you need a computer with Internet, you will be able to find one, even if the network is being funky.
