I have followed the instructions written by Will Haley here to wifi bridge a waveshare RS485 to RJ45 Ethernet Module via a raspberry pi 3. The script ran normally without any warnings or errors, and after reboot I’ve connected the waveshare ethernet cable to the pi, the link green led turned on the waveshare, but it hasn’t been assigned an IP, as far as I can tell via the router webpage and my nmap queries.

I know that the instructions are for a pi 4 rather than 3 but I don’t think that would be the reason why I cannot see the IP of the waveshare?

When I run ifconfig both eth0 and wlan0 display the same IPv4 and am not sure if this is normal?

Another thing that I have noticed is that sudo systemctl status dhcpcd.service
outputs the following error message

Aug 10 15:42:43 rpi-solax dhcpcd[614]: wlan0: DHCPv6 REPLY: No Addresses Available

I don’t use ipv6 addresses in my home network. Could this be the root cause of the issue and if so how can I fix it? Thanks in advance.
