restoring wireless connection to iMac/Canon9223
I've been successfully linked from my iMac to the Canon printer for several months. Suddenly, the c computer no longer "sees" the printer. When I try to restore the LAN from the printer, it tells me to "press and hold the WPS button at the access point". I cannot find any WPS button ... at the router, nor by Airport Extreme.
Ideas?
