This guide explains how to fix Wi‑Fi and GPU driver problems on CentOS 8 by booting an older kernel instead of the newest update. It walks you through listing all installed kernels with rpm, selecting a stable version that works with your hardware, and noting the exact package name for later use. The instructions show two ways to make GRUB default to that kernel – either using grubby to set the path directly or editing /etc/default/grub and regenerating the config with grub2‑mkconfig. Finally, you can test the change by rebooting, verify the menu preselects the chosen entry, and when ready revert to the newest kernel with another grubby command or restore GRUB_DEFAULT=0.
The article walks readers through turning on IPv6 support for Nginx, starting with checking whether the kernel allows binding to IPv6 addresses and enabling it if necessary. It then shows how to add explicit `listen [::]:80` (and optional SSL) directives inside a server block so that the web server can accept both IPv4 and IPv6 traffic. After performing a syntax test with `nginx -t`, the guide advises reloading the service safely, verifying connectivity with curl on the loopback address, and troubleshooting potential firewall or security module blocks. Finally, it lists common pitfalls such as duplicate listen lines, port conflicts from containers, and post‑upgrade IPv6 disables, ending by stressing that enabling IPv6 is a simple configuration tweak that ensures mobile and IPv6‑preferring visitors reach the site.
