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!

Yes, all of my network names appeared.  I tried a different wifi network, but it still doesn't work.  The IPv4 address showing on the printer is different than the IP address that is showing when I pull up the printer status...but yes, I will hop on and try the real time tech support.

I have had this same problem with 2 canon Pixma printers so far. I have tried the Wifi connection assistant, adding through windows. resetting the network settings. it simply WONT connect to the printer, I have a complete unopened box of ink that i cant use right now, because i cant connect to my printer. I only buy genuine ink (same store i bought the printer at) and still nothing. I tried both wireless and wired connections and still wont connect. and i cant even connect with my computer to see the settings.  I bought the product, i should not have to pay extra if the thing doesn't work to get it fixed.  This is the 2nd printer in 6 months that this has happened to. I guess i will be going with Brother Printers from now on.
