> Try entering a long wifi-password via the 1-line lcd and 2 buttons on the printer, what a nightmare.

I used the WPS button method [0] to set up my Brother printers and it worked perfectly for me. Definitely much more pleasant than trying to key in a long password.

My router doesn’t have a WPS button, so I also had to use the two button interface. Not fun having to cycle through some 50 plus ASCII characters for the WiFi password. I’m pretty sure you can emulate the button press in openwrt with some package though. It was faster to just enter the password than to figure all that out.
