My new HP Deskjet 3755 won't connect to a new network Wirelessly

[Ardara]

I have one of these in my other home as well. Loved it, so bought a new second one in Canada two weeks ago. Hooked it up wirelessly to my Bell network,it worked fine from 4 iOS devices and a MacBook. Then we moved. New ISP (Rogers), new network name, new dual network modem, new password. Cannot get the printer to change its loyalties. Made sure modem and iOS devices were on the 2.4 GHz network. Have been googling and working on this all day, it is frustrating, I haven't cooked a meal or unpacked a box. I figured out how to print a network configuration page, it clearly shows the old network despite all my efforts I don't know how to change it. Tried turning off modem, turning off printer, restarting. I tried all 3 methods in the quick start guide, and from the AiO app. Hey we are over 60 so old geezers and yet we think not too stupid, and very persistent, but can someone give us a hint? Please? We're getting hungry. 😞

Page 57 tells you how to connect your printer to your new router.  Make sure you have your Printer USB cable ready.  Do not plug the cable in until told to do so by the software.

Thank you for the link to this.  The page 57 instructions didn't work for us but reading further we were able to print what we needed using the instructions on page 59, printing without a router. But this is a bit cumbersome for daily use as it seems a bit of a workaround. And then you have to reconnect to the router to use your device, well okay that isn't such a hardship. We are probably misunderstanding how this works. There was a technique we thought looked promising for printing wirelessly by cabling the router to the printer directly. We looked yesterday for the correct Cable but it was $24 in the shop and was 12 feet long,  so we didn't buy it. We will try to find a shorter Cable. But meanwhile my network configuration still shows the new printer thinks it is solidly connected to my old, non-existent router and Bell network. But thanks, at least we figured out a workaround for our urgent paperwork situation, based on the link you sent us. 🙂

You need a Printer USB cable like this.

Now you rerun the setup software and plug the USB cable in when told to do so.  Set up the wireless and the settings are transferred to the printer via USB cable.
