Deskjet 3755 cannot see network

[StrangeAttractr]

I bought this printer new and am trying to replace an existing HP printer that died.  I have gone through all set up recommendations and troubleshooting to no avail.  I even reset and reconfigured the router.  HP Smart eventually finds the printer, but also says "internet unavailable. Cannot auto-connect".  I've tried WPS to no avail. 

The printer's Wireless Network Test Results say its Wireless PASSes for On and Working, but says the Network Name/SSID Found FAIL.  NOTE:  this printer only access 2.4 Ghz wireless, which I have and it's running (and the name of that  network is unique.  I also changed my phone to that network and retried all the auto setup steps - no luck). 

I don't have a USB-A cable, so that hasn't been tried.  I hate to buy one just for a 5 minute setup process.  

I had a lot of struggles with setting up tree former printer, until i learned about the 2.4 Ghz restriction, but it has worked flawlessly for months since then.  Unfortunately, it hard crashed ( it will no longer even power up).

What the heck can i try now?

I did find a way around - with a laptop that had existing HP software.  When i changed that to the 2.4 Gh network, i was able to add the printer successfully.
