Pixma TR8622a is suddenly offline after working just fine

[Racktree]

I have a brand-new Pixma TR8622a (my first Canon printer product).  I installed it successfully, printed several items from computer, phone, tablet, etc.  Two days later, the printer suddenly shows not connected.  I turned it off, unplugged it, plugged it back in, but still nothing.  The printer status shows that it has a good wifi connection; however, the Canon printer diagnostic tool (on my computer) says that there is no signal from the modem and recommends I move my modem closer.  For reference, my modem is less than ten feet from my computer/printer.  I am pretty good with electronics and this is making me very strongly consider returning this printer and going with a different brand.  Any help would be appreciated.  Thanks!

Mine is registered, but still cant get support for it. I guess I will be going with Brother printers since I have 2 Canon printers that are glorified paperweights right now.

Hi,

Since it tell you that it is connected, please perform the steps HERE to print the network settings. Is there a signal strength listed in row 3-2-1? 

Also, Please open a web browser on your computer, and in the address bar, please type the IP Address(Row 3-2-12) on the configuration page into the address bar. Next, tap Go or Enter to access the page. Are you able to see the printer's remote interface?

We look forward to your reply.
