I'm still using an ancient Kobo Touch / N905B for my ebooks... It's mostly ok-ish, but had an super annoying problem that kept reappearing over the past couple of years:
After firmware updates, Wifi was rendered unusable. The system forgot all saved networks, and was not able to find or connect to new ones. Its "Edit Wi Fi networks" screen just hung for minutes, only to turn up empty.
The only workaround was to do a full manual reset (cache) (boot with the home button held down, which wipes everything and restores the original 2012 firmware), and then reinstalling a current version. Only after the next update, Wifi would be broken again.
I was about to give up on the device, but then tried something slightly different on a whim: Did the manual reset, but then skipped device registration, and did not turn on Wifi in that state, while running the old firmware. I then copied the latest version from the KoboStuff Firmware Archive to the device via USB, rebooted into that version, and only then tried connecting to my Wifi network.
The problem hasn't reappeared up to now, but I really have no useful explanation why that order of steps should make any difference... 🤷♂️
