The url in my /etc/opkg.conf is not available anymore, so I pulled up a browser and went back in the directory path until I found that http://archive.openwrt.org/snapshots/trunk/ar71xx/ exists just fine but now, it has three sub directories:
generic
mikrotik
nand
and I'm really unsure which path is the right one for my router, how can I find out?
But you have a really ancient firmware if you have not that generic in the path.
You have a 4/32 decice that will not run the current 18.06.1 well. Likely.
You should update to 17.01.x release from that arbitrary anicient trunk snapshot from 2016 or earlier.
The core OpenWrt starts to be too large for devices with only 32 MB RAM or only 4 MB flash.
17.01.x is practically the last modern release that can be recommended for those devices.
