Does the apple adapter of the link below work to avoid a wifi router?
If you still have Lightening on you iPad, it seems to be the case, yes. If you have USB-C like me, any USB-C to Ethernet adapter should provide the same functionality.
Thank you. I have ipad with usb-c. I will buy one
FYI, I use this one which can do much more than Ethernet and works very well:

Anker 6-in-1 USB C Hub with 65W Power Delivery, 4K HDMI, 1Gbps Ethernet, USB Ports for MacBook Air, iPad Pro, XPS, and More. Looks great.
