on my DIR-825-B1 I have to use an copy of Netscape navigator
on windows 10 to upload the firmware to work
I'm sure the page comes up in modern browsers but fails
I do also know on the DIR-878-A1 & DIR-1960-A1 you can't use linux
only really work under windows tho lots keep trying
I use Firefox in Private mode "no cache" on those models
I'll leave it to someone who has that specific model
