Xen: Based on what you have described, something is going wrong with your Kobo.

All my Kobo ereaders remember the sort sequence across reboots if I use the library link at the bottom of the home screen. If I press the library tile in the home screen, the sort is change to "recent" and remembered from then on.

The "forced to login" is almost definitely because the internal database on the device was corrupt. This is used to store details of all the books on the device, the annotations, the shelves and lots of other things including the Kobo user. If you powered off and on and was prompted for a login, then the database was in a very bad way. Because of this, a new database was created and you were prompted to login. After that, it had to reprocess all the books on the device plus download a few books you purchased from Kobo.

Neither of the above should happen. I haven't had to do a login for months except when I deliberately did something to trigger it.

The database corruption is a concern. Some people seem to see them a lot, some never. Unfortunately, we don't know what causes it. The only way we do know is not safely ejecting the device from the PC when using something that accesses the database on the device. This includes calibre and the Kobo desktop app. We have seen a few reports here where people have continuously had corrupt databases. It turned out to be a faulty device and they were able to exchange it. And everything worked fine afterwards.

As I and the others have said, you don't need the WiFi for normal operation. This is unless you want to buy books from Kobo and sync the status. That is very handy if you are using multiple devices to read. But, it isn't mandatory. As others have said, they do the setup and turn WiFi off. But, if you want to avoid that, you can update the database to have a fake id and skip the setup. The device will still work, and WiFi will still work, but it won't sync books or anything with Kobo. A search of this forum will find the instructions for doing this.
