I have HP 530 laptop, I installed Ubuntu 12.10 OS. I am unable to see/enable wireless network. Please help me with this.
Your question does not specify if you have the wireless access and your internet is running fine with no network icon at top panel.
Well, if your network is at fault,
Open the terminal with CTRL+ALT+T .
You should get a similar result with wireless lan 'yes' for soft-blocked.
You can fix this by typing the following code in terminal and rebooting the laptop.
If the internet access is fine and the networking icon is missing, type the following lines into the terminal and the panel should be working fine.
