Downgrading OpenWrt on WRT3200ACM
After I upgraded to OpenWrt 23.05.3, my Linksys WRT3200ACM WiFi router seems to interact poorly with my Dell E7470 laptop. It takes many tens of seconds for that laptop to acquire an IPv4 address via DHCP.
I decided to downgrade OpenWrt Linux on the router from 23.05.3 to 19.07.10. I believe it was running 19.07 before I started on my sysadmin journey of switching to a new server.
