After jailbreaking, lost the wi-fi signal indicator on upper left hand

Actually jailbreaking is easy. Just went to the site let it install and voila installed cydia. Now my questions;

Where is the signal indicator and the rotating search of my Wi-Fi by the "IPAD" on the upper left hand corner?

Second, I installed openssh on IPAD and access it from my Buffalo (hacked with debian linux) changed password and why I cannot use simple commands like netstat, ps, top, du ifconfig, etc?

Thanks,
Tik

The issue cause by the Open SSH, you may install the Respring from Cydia and your wifi icon will come back.:)
