When “Pre-Installed OpenWrt” Isn’t Plug-and-Play

  Lessons Learned After Finally Configuring a Raspberry Pi CM4 Mini Router (Bought in 2022) Product Mini Router built with Raspberry Pi Compute Module 4 Dual Gigabit Ethernet NICs 4GB RAM / 32GB eMMC Pre-installed OpenWrt Compact form factor, fanless, low power Background: A Device That Waited Its Turn I bought this device back in 2022 . At the time, it looked like the perfect small router: Raspberry Pi Compute Module 4 Dual Ethernet ports OpenWrt already installed No SD card required thanks to eMMC But like many homelab projects, it ended up sitting on a shelf . Fast forward to today — with more networking experience, a clearer home network plan, and a real need for a flexible router — I finally decided to configure it properly. That’s when the real journey started. What I Expected (Even in 2025) Even knowing this wasn’t a consumer router, I still expected: Plug WAN into my upstream router Plug LAN into my laptop Access 192.168.1.1 Hav...

Adding Users to Existing Groups in Ubuntu (Oneiric Ocelot)

Hi have been working in Virtual Box, this days and need to add my user to the vboxusers group. I was going to do it graphically, and suddenly I notice that the application I use for doing this job it disappear. :( So I have to use the CLI If you know the group just do this Steps sudo usermod -a -G GROUP USER where -a means append. Add the user to the supplementary group(s). Use only with the -G option. If you want to read more about the usermod do man usermod If you don't know the group Steps groupmode 2 TIMES sudo usermod -a -G GROUP USER If you see the only difference is that you type groupmode and press tab 2 times and all the groups will be display. HOPE it works
