Can you post the outputs of lspci -nnk | grep -iA2 net from a terminal window. – mikewhatever Sep 21 '12 at 20:07
Some Intel wireless cards are know for ennoying blinking, but, as far as I know, 3945AGN, 4965AGN (and likely others) have a module optiion to disable the blinking. Just need to know which module is in use. – mikewhatever Sep 21 '12 at 22:25

If the wireless is just not "connected" you can, depending on lots of things, still see activity when it probes for available access points.

A simple solution is:

:~$ rfkill list  
0: hp-wifi: Wireless LAN  
    Soft blocked: no  
    Hard blocked: no  
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
:~$ rfkill block 1

To re-enable wireless:

:~$ rfkill unblock 1

I seriously doubt "my computer is slow" is related to wireless directly. More likely an under-powered graphics card pushing unity.

This is tested with an Intel Pro 5100 AGN.
