Overview
Editorial opinionThe Brume 2 is a palm-sized wired router aimed at VPN gateways and small offices: one 2.5 GbE WAN port, one gigabit LAN port and no Wi-Fi. Pair it with a separate access point.
OpenWrt installs from GL.iNet's web interface. Note that recovering a broken install may require a serial console.

Installation difficulty
Editorial opinion- Installation difficulty
- Easy
- Usual method
- Upload the OpenWrt sysupgrade image in the GL.iNet web interface without keeping settings.
- Recovery difficulty
- Hard
- Recovery method
- According to the OpenWrt commit, the vendor U-Boot recovery does not accept images, so recovery requires a serial console.
Our rating of how hard a first installation and an unbrick are for someone comfortable with a web interface. Always follow the official device page for exact steps.
