When I plugged in my Raspberry Pi 5 for a new project last month, nothing happened on screen. No boot splash, no login prompt, just a green LED blinking in a pattern I had never seen before. That moment reminded me why Raspberry Pi green LED blink codes are worth memorizing. They turn a silent, … Read more
Setting up split-horizon DNS is how you make sure a laptop on your couch reaches your reverse proxy over the local network instead of bouncing out through your public IP. I run a homelab with about a dozen self-hosted services, and the moment I pointed my family’s phones and laptops at a real domain name … Read more
Last weekend I set up a site-to-site WireGuard tunnel between my house and my parents’ place so I could reach my home file server without poking holes in my router. It took me about an hour, most of which was figuring out two things: which subnet to give the tunnel, and why my traffic made … Read more
I remember the exact moment I hit this problem. I had spent an entire weekend setting up a Nextcloud server on my home network. Everything worked perfectly when I tested from my phone on cellular data. Then I walked back inside, connected to Wi-Fi, typed my domain name into the browser, and got nothing but … Read more
When I copy a 200 GB file across my home network and watch the progress bar crawl at 4 MB/s, the first question I ask is not “is my disk slow?” It is “is this a network problem, or is something else getting in the way?” That single question is the reason iperf3 exists. In … Read more
Handing your Wi-Fi password to a contractor, Airbnb guest, or that one relative who always needs the internet feels harmless. Then you remember they now have a direct line to your NAS, your security cameras, and every smart bulb on your home network. A properly configured guest Wi-Fi VLAN fixes that problem completely. In this … Read more

The error means your Linux system cannot detect any wireless network hardware, and in most cases the root cause is a missing or mismatched driver for your … Read more
Installing Broadcom Wi-Fi drivers on Ubuntu when you have no internet yet is a chicken-and-egg problem I have hit personally on older laptops and a 2013 MacBook Pro. Ubuntu will not include the proprietary firmware Broadcom needs by default, so a fresh install often lands you staring at a “no wireless adapter found” message with … Read more
Realtek RTL8125 Linux support is one of those headaches that looks simple from the outside and turns into a weekend project once you start digging. The 2.5GbE controller ships on countless motherboards and PCIe cards, but the in-tree kernel driver does not always play nicely with it. I have rebuilt this setup on Ubuntu 22.04, … Read more
If you’ve ever booted into Linux only to find your Windows drive suddenly unavailable, you already know why a reliable NTFS workflow matters. I run a dual-boot workstation, and for the past three years I’ve mounted NTFS partitions daily for everything from document edits to Steam libraries. This guide collects everything I’ve learned about how … Read more
