|Does it work when connected via ethernet/cat-5? Presuming it allows either cat-5 or wifi connections, are you trying to use both ethernet and wifi at the same time! |
Canon etc. generally don't allow both at the same time; although I have managed it with some Canon inkjets - and XP in the past.
Did you follow Canon's setup procedure to the letter? Start with usb enabled, then enable networking etc? Canon at least are very picky and specific about order of installation of "all" driver.
Do you - and have you read - the manual re' proper Canon installation routine?
