I did initially have to fix a DNS problem, but can now resolve and ping external domains by their name and 'date' returns the correct time and date.

On my main router (Watchguard T70) I now run 'apk add' instead of 'opkg install' and that runs fine, so do I need to upgrade the firmware? On the Zyxel WSM20's I am running either openwrt-ramips-mt7621-zyxel_wsm20-initramfs-kernel or openwrt-ramips-mt7621-zyxel_wsm20-squashfs-sysupgrade. Not sure which one since I installed it some time back,

If I try to open the individual packages in the browser on my laptop, I get a 404 not found error.

I am actually trying to get umdns installed in an attempt to resolve an mdns resolution problem with my UNO Q as it simply does not show up in mdns-scan or avahi-utils.

You will need to sysupgrade to 25.12.x or a contemporary snapshot, both of which will give you apk(-only).

Thank you. I found the relevant sysupgrade file for the device and have now installed it on both WiFi APs. The process was quite painless and I can now install apk packages. I then just ran 'apk update' and 'apk add umdns' which installed and automatically enabled umdns, Unfortunately this did not solve my mdns problem, which is another story and the subject of another thread, but the router firmware is now upgraded.
