MB5320 - Wifi keeps disconnecting

I have had it with this printer.  It is brand new and it keeps losing the wifi connection.  Customer service helped me last time to set it up and was working properly but it has lost the connection again and it seems this is a huge problem no matter the model in Canon printer.  


I am really disappointed that I bought a brand new printer but can not print because the wifi keeps falling off and says:


Support Code : 300 The printer does not respond. Make sure that the printer is plugged in, powered-on, and properly connected to your computer.

Re: MB5320 - Wifi keeps disconnecting

Hi pucca94957,


Support code 300 is a Macintosh code that indicates a network communication problem, so let's start by checking the printer's connection to the wireless network.  Full instructions for printing the Network Configuration Page can be found HERE.


Much of the information will not be relevant, but the important things to look at are:

  1. Is the connection active or inactive?

  2. Does the SSID (network name) match the one the computer uses?

  3. What is the signal strength?

  4. What is the IPv4 IP address?

I look forward to your reply.
