Setting Up A Canon Printer on Wifi (specifically the Pixma MG5422)

I initially had no problems setting up the printer or even the other computers and devices in the household, or none to cause serious delays.  It did take me a while to figure out how to get the APP set up on my phone, but relatively painless.  

HOWEVER, when I moved the primary desktop,  having helped my son build a gaming computer over Christmas, it took TEN DAYS for me to get the printer back up on the network.  Here’s what it took.

A.  A call to customer service.  

   I really feel this is something that should be accomplished without calling in professionals, so I never do.  However, after having my mother in the hospital for 8 days, suffering the loss of a family friend, and being physically, emotionally, and spiritually exhausted, plus having the graphics card rebate due in two days, I managed to find the fortitude to pick up the phone.  

  West Virginia helped me with these facts, which are not stated on the Canon website.  

• in order to reseat your drivers, the drivers need to be downloaded from the Canon website, especially if you are like me and can’t find the installation disk.  
• in order to download said drivers, you HAVE to use Internet Explorer.  Having used Chrome for 10 days, I was very irritated that there is no warning on the website to this effect. 
• you HAVE to delete your prior printer from “printers/devices” before updating the driver for it to work well, again this is not on the website.  
• There is a way to get a printout of your wifi strength, and see whether the printer has found your IP address.   EVEN IF it says it is connecting to your WIFI, if it has forgotten your IP address, you still have problems.  The only way I found to translate that information was to get a computer close enough to the printer to hook it up by USB.  After that, you can go through the process of telling it you want to switch to LAN (which is another name for WiFi, which the average person does not know…why all the lingo to get a printer set up?  I have no idea.)
• Once the IP is submitted to the printer, it should feed over the network, BUT EACH device on the network has to have the driver update done in the same way (through IE, having deleted the old one first). Also, it is good to clear out the print jobs in the printer cue, and reboot the computer before downloading the new driver, otherwise, you have to start over. 

I hope these helps some other soul.  I was at my wits end, and though I was initially pleased with the printer, this was annoying.  As annoying as setting up my HP after it lost the settings.  I had to call customer support every time, and they only did it free up to a year.  With inadequate documention.  Listen, printer companies, if you want us to do it on our own, give good directions.
