If you are unable to use the ETSUWiFi please forget or delete the network settings on your device and set it up again. Certain devices have cached an expired certificate preventing proper use. For help re-setting up ETSUWiFi on your device, see Wireless Setup Instructions. The Help Desk at 439-4648 can offer some limited assistance, but please try the online instructions first if possible. Windows 8 users will need to uncheck "Validate Server Certificate". See step #6 of the Windows 7 instructions to see the relevant setting.
