I recently got a Netgear GS105Ev2 and GS108Ev3 managed switch and wanted to update their firmware. The GS108Ev3 updated easily through its web interface, but the GS105Ev2 required a different approach using TFTP. Here’s how to do it on Mac OS.
- Download the latest firmware from the Netgear support site
- Extract the downloaded .zip file
- Download the MacTFTP Client
- Connect your Mac and the GS105Ev2 switch directly to each other with a wired connection
- Remove all other network cables from the GS105Ev2 switch
- Power off and power on the GS105Ev2 switch
- Configure your Mac to use a static IP address of
192.168.0.1with netmask255.255.255.0 - Connect to the GS105Ev2 switch via web browser at
http://192.168.0.239with passwordpassword - Head to Maintenance → Firmware Upgrade and press “Enter Loader mode”
- Change the URL manually to
http://192.168.0.239/index.htm - Fire up the MacTFTP Client downloaded earlier
- Select “Send”, use
192.168.0.239as the address andpasswordas the password - Select the firmware file using the “File…” button and click “Start”
- Wait for a minute for the upload to complete, then for the switch to update and reboot
- Connect to
http://192.168.0.239— it will ask you to upload the-VB.binbootloader update file
