/etc/config/wireless getting overwritten on reboot

I’ll take your word for it. I tend to stay away fr UCI as I’m just so conditioned to directly edit the conf on my various Linux boxes. You may want to do the same; opkg update && opkg install nano is a Helluva lot easier for editing if you’re not intending to spend a lot of time in sysadmin/programming work.

A good SSH client app will let you just paste your above conf directly into the file as needed. See the References & Resources of
