Congratulations - you are on your way. Now Sergey's instructions on configuring WiFi should get you the rest of the way. Use DHCP and WPA or WPA2 if you can - that comes right up. No encryption is a bit harder...
Your no response at the terminal window was likely due to the reboot button bug in 0.7.5. Expect to have to recycle power to reboot until you move to more recent firmware.
