I just got a new Canon MG 7550 all in one printer, set it up so it prints wireless, it worked fine on initial set up but when i shut down the laptop or printer it will not let you print wireless, a pop up box appears informing you printer not found, can anyone offer any help please, Canon customer support very poor still waiting on a reply a week later.
I have a Canon MG6450 which may be a bit different. In the information screen has 3 pages - normally set on Copy/ Scan/Cloud. On page 2 is the WLAN that can be on (blue light showing on left of top dashboard). Is the blue light on? Maybe it was inadvertently switched off ?
I have a Netgear router which shows (In "Netgear Genie") what devices are on the net - maybe your router has such a menu?
I have had this problem with Epson printers. It was caused by the router allocating a different IP address after the printer was switched off and back on again and the pc was looking for the old address which it could not find. Hence my suggestion of allocating a fixed address.
