Turning on wifi freezes computer

If you boot with the wifi on, is it ok?

Can you give the output of:

sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list

Thanks

I can get to the login page, at which point I push fn-F3 to turn it off, but if I login, and put in the keyring password, it freezes.
Here is the output:
alan@alan-laptop:~$ sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list

Seeing as no one has responded, this makes me think that this is a unkown bug. Should I file one?

Makes sense.

Do you dual boot the system?

No i don't dual boot.
