I bought this MF 212w printer a week ago, this is the third time I use this printer. It just can't reestablish connection with router when I turn it on. Power off and on didn't help. and rebuild connection with router throught setting didn't work either.
I will be able to assist you.
Please try power cycling the router while th printer is off. To power cycle the router, unplug it from the wall for 30 seconds. Once the router is back on, please turn on the printer and verify if it is able to connect to the network.
