Hello
On my laptop (with ubuntu 12.04), the wifi with my ZyXEL p-660hn-t1a routeur did not work.
I post this since I did not find anywhere on the net how to solve this (I even found a post saying that it was impossible to solve).
The solution for me (which was given to me by ZyXEL) was to settings of the routeur Network > Wireless LAN > AP> Advanced Setup and then put "802.11b only " for the 802.11 mode.
Hope it will help
