Hi all

I install the Ubuntu 9.04 my old Lenovo Y520 laptop, the wirless does not work.My Wireless card is Intel Pro/wireless 2100 card. But I can not enable it. My wired card is working well. Does anyone meet it before.

the ifconfig output is

I have another question. When my OS is 9.04, there is a icon about network connection on the panel at the top. After I upgraded to 9.10, that icon disappeared. How can I get that back?
