Netgear GS108Ev2 Firmware Upgrade and VLAN Tagging
I had quite a lot of fun the other week trying to upgrade a new Netgear GS108E switch followed by VLAN tagging a specific port so it could be part of the guest network VLAN.
First challenge was to upgrade the switch as it was on a really old version of the firmware… This part alone took 3 hours… so hopefully this will save someone the hassle I went through.
1) Download the latest firmware from Netgear for your switch
2) Make sure you’re on an ethernet cable that goes directly to the switch with no intermediate switches. Do not use wifi
3) Remove the incoming dhcp connection cable from the switch so it’s only your PC and the switch connected to one another
4) If you have more than one switch in your network setup, remove the ARP entry for the switch (Command Prompt -> arp -d (so probably arp -d 192.168.0.239)
5) Disable your PC firewall, antivirus and anti malware (in my case this was windows firewall, Avast and Malwarebytes)
6) Now run up Netgear ProSAFE Plus Utility and select the switch and proceed to upgrade the firmware by pointing it at the relevant firmware file
Next challenge was to VLAN tag the particular port in question but leave the rest of the ports untagged. This was another 2 hours of trial and error + a bit of help from a couple of pages found when googling the issue.
The magic combination was…
