http://ubuntuforums.org – Hi, I have Desktop PC Dell Inspiron 530, Double boot with Windows Vista. Worked OK with DSL. Verizon technician could set up wireless on Windows Vista but Could Not on Ubuntu 11.04. Internet on Windows Vista works OK. I don't have internet on Ubuntu, cannot download any driver, unless there is a way around it. Printed on the USB Adapter box: USB wireless N-lite USB Adapter is N220 by ZyXEL. 802.11n compliant and backward compatible with 802.11b/g Network connections Setting on Ubuntu filled out, but no connection. What should I do to make it work? (Hardware)
