Download Firmware Ubiquiti EdgeMAX EdgeRouter 2.0.9 Hotfix 4

Ubiquiti Networks has released a fourth hotfix for version 2.0.9 of the firmware for the EdgeMax EdgeRouter. The EdgeRouters are characterized by extensive setting options, but do require some network knowledge to get it running properly. Also, not all settings can be adjusted via the gui, so you have to go through the command line. The list of changes and improvements for this release is as follows:

Overview

The ER-X/ER-X-SFP/ER-10X/EP-R6 has more limited storage, and in some cases, an upgrade may fail due to not enough space. If this happens, remove the old backup image first (using delete system image CLI command, see here for more details) before doing an upgrade.
