Error message: Invalid WEP Key
Cause An invalid WEP key was entered.

setting of the HP All-in-One.

was changed on the access point, open the Embedded Web Server for the HP All-in-One and
update the index setting to match the index setting of your access point. Once you've updated
the index setting on the HP All-in-One, re-run the Wireless Setup Wizard.
