GL.iNet Comet Pro (GL-RM10) Review: The “Family IT” Remote KVM Fix
Published 29/01/2026
Description
If you’ve ever been the family IT department, you know the pain: Remote Desktop works… until it doesn’t. The PC isn’t booted yet, you get stuck in a separate RDP session, someone closes the lid, or they panic-click disconnect while you’re trying to fix something. In this video I’m reviewing the GL.iNet Comet Pro (GL-RM10), a remote KVM designed to give you true out-of-band style control: keyboard, video, and mouse access even before the OS loads (BIOS-level access), so you can troubleshoot like you’re physically in front of the machine.

Networking options for real life: Wi‑Fi 6 (dual band 2.4/5 GHz) vs gigabit Ethernet, and how I’d think about failover and placement. Setup + access methods (the practical bit) I go through first-time setup on the touchscreen, then how you actually connect to the device locally using glkvm.local (or by IP) in a browser (Chrome/Edge recommended). I also cover remote access options such as GL.iNet’s cloud workflow and the GLKVM app, plus where the “cloud convenience vs local-only control” tradeoff starts to matter. Full UI tour (so you can see everything before buying) I’ll walk panel-by-panel through the web configuration: video settings, connected devices, system/network settings, status indicators, accessories, virtual media, logs/help, firmware update, and reboot/logout flow. Security and “can I lock it down?” Because this is a device that can literally control a computer, I treat it like critical infrastructure. I cover: Hardening basics: change admin password and enable 2FA. Browser certificate warnings on local admin panels, and how the Comet Pro can use a real (or self-s
