Trying to install sysupgrade on Netgear RBS50 satellite

I'm a new user. Just installed openwrt on my RBR50 (main router) and RBS50 satellite. Set up the satellite in AP mode. So far - everything seems to be working. I wanted to make sure I could install upgrades so I ran opkg update on the RBR50 downloaded a long list of items. Found the Attended Sysupgrade package and got that installed on the main router. I haven't actually done an upgrade but it successfully downloaded 24.10.7. When I try to do the same thing on the satellite device it runs the opkg update but returns error messages. Several of them say, "Failed to send request: Operation not permitted". Messages also say, "Check your network settings and connectivity."

I changed the satellite wan6 settings for DHCP ipv6 to "relay mode" and that allowed the opkg update to run. I got a full list of available items. Selected the attendedsysupgrade-common version 9 and installed it. It shows as installed but it doesn't come up on the system menu like the main router.

Thanks in advance for any help you can provide.

Add default gw and DNS IPs next to device IP.

Probably a caching issue somewhere. Try ctrl-shift-r on the browser, and if that doesn't work, just bail and reboot the device itself.
