@linuxdev Hi, thanks for your reply. I read your comment in other page : your comment
In my case, I am using jepack5.0.2 which is higher than 4.3.1 so can I reflash and upgrade jetpack up to 5.1.2 with apt command? My jetson board is attached to other board so It is quite difficult to reflash it by pressing the power button located below the Jetson board.
BTW, even if it is possible to update wireless, for some reason I have to stick to jetpack5.0.2 as much as possisble so I will try reflashing method at last if other methods don’t work. Can you see any other suspicious things except l4t version in my post? Thanks.
