1. Your tablet runs Honeycomb and not ICS.
2. You have an HTC phone (or phones not supported by FoxFi in WiFi mode)
This version uses a web proxy solution tablet and connects over Bluetooth. Please install FoxFi on your phone and enable Bluetooth mode then connect from this app.
Warning: do not uninstall this app from your tablet before making sure sure Proxy Setting has been cleared and saved. Otherwise your tablet will not be able to go online again without a factory reset!
