Thank you for your support!
To install software I wanted to download the packagelist. This fails because of the accessibility of some addresses under which the lists are to be had.
If I enter the same addresses in the browser running on the computer connected to the OpenWRT router, I immediately get the downloads offered.
IPV6 is disabled in the interfaces of all devices.

The opkg update command failed with code 6.
Is your OpenWrt device acting as the primary router on your network, or does it serve some other purpose like a dumb AP?
Please copy the output of the following commands and post it here using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:
First guess: Based on your earlier messages, you have several routers. Maybe you have defined a static IP address for the new router, but you have forgotten to define DNS and gateway, which likely should be the main router of your network.
(The PC gets them via DHCP, but the router with the fixed/static IP does not get any info via DHCP and you needs to specify the DNS server address, usually your main router)
Under Interfaces>WAN>advanced settings "use default Gateway" is activated. The main router is specified as the gateway under Interfaces>WAN>General Settings, i.e. the same router that is used as DNS by the clients from which the download works.
Had the same using OpenWrt as dumb AP and solved as @Cableghost suggests. In my case I checked "Use default Gateway" and set "Use custom DNS servers" = my main router's IP in LAN interface.
Yes, it is like this.
Under Network>Interfaces>WAN>Edit, the address of the main router was set under "Use Custom DNS servers". After that, the software list could be downloaded.
