So here's a quick poll:
Do you use Ubuntu on a laptop + wifi?
And, if you do, do you use
no encryption / WEP / WPA / WPA2
with ESSID broadcast / hidden?
Yes, Ubuntu on a Dell Inspiron, I use WPA, used to use WEP when my
desktop card didn't support WPA. I used to have the ESSID hidden when
I was using WEP but don't bother any more as it's WPA that's giving
all the security.
