Problems with wireless

[OSUTIN]

Hey everyone, I just installed Ubuntu on my laptop (again after quite a while), and am experiencing difficulties with my wireless. My laptop is an HP G62 Notebook PC, and has a physical hardware button on the keyboard to turn wireless on and off. When off, it is orange, when on, it is white. When I first installed Ubuntu, it was orange, but I could turn it on. But it didn't pick up any wireless networks. Now, I am unable to turn it on, and the wireless option in the network menu has completely dissapeared. Before deciding to make an account, I tried a variety of things I found, but nothing seemed to work. At this point in time, any help would be appreciated. Thanks in advance! And just tell me whatever terminal commands you want me to use, in whatever order, but do note, as it has been a long time since I've used Ubuntu, I'm not entirely familiar with the terminal anymore (not that I was ever really familiar with it, in comparison to people who use Ubuntu regularly).

Bump. I know I'm ever so slightly vague, but please help. I'm noot a total noob/knob, like my original post may have made me out to be...

Please show the outputs of:

lspci -nnk | grep -iA2 net
lsmod

Try

sudo rfkill list

Press Enter and insert your password.

Submit the output.

BTW have you installed any network manager (nm-appled, wicd....)?

[OSUTIN]

Even with Sudo it returns nothing. And I don't have any network managers that I know of.

Install the package "b43-fwcutter"
