Hi Toni -- I was wondering about Wi Fi too, and in Post #419, sandi posted the link that shows the arena has Wi Fi. Hooray!
Hey guys! I'm a local so just giving the helpful tip that there's free public WiFi in the heart of the downtown area like where the Fairmont hotel is on Market/1st street. The WiFi doesn't cover the area right next to SAP Center though. You can see the coverage map here. http://www.sanjoseculture.org/index.aspx?nid=3689
