GS108Ev2 incorrect password after restoring configuration
I have 3 Netgear GS108Ev2 switches. All 3 units have firmware 1.00.12, and I'm
using the Prosafe Utility v2.3.20
Recently I reconfigured the VLANs in my local netowrk, and after modifying the
settings on the switches, I decided to go back at least temporarily, so I
restored my saved configurations. They used to work fine, and I had already
restored at least one of them before.
However, after restoring the configurations this time, I can't log in to the
switches anymore. The old password doesn't work. The configurations had been
saved with Prosafe Utility v2.3.5, so I thought that might be the issue. I
uninstalled v2.3.20 and reinstalled 2.3.5, then I tried to restore the configs
again. Nothing helps: I can't login to the switches.
What can I do?
Suggestion added. It's here:
Thanks!

Hi inky,
Welcome to the community! :)
Kindly answer the questions below:
a. What was the firmware version of the 3 GS108Ev2 switches before you have upgraded it to firmware v1.00.12?
b. Have you tried to perform a factory reset the 3 GS108Ev2 switches before you have restored the configuration?
I look forward to your response.

Hello DaneA,
thanks for your reply.
a. What was the firmware version of the 3 GS108Ev2 switches before you have upgraded it to firmware v1.00.12?
I don't remember. The firmware upgrade was done long ago. I'm pretty sure that after upgrading I edited the settings, saved configuration, restored it, edited more, re-saved configuration, etc. several times. The lost password problem only emerged this time, several months later, after I'd updated the Prosafe utility - not the switch firmware. Maybe it's not even related to that.
b. Have you tried to perform a factory reset the 3 GS108Ev2 switches before you have restored the configuration?
Yes, all three of them. After resetting them, the hardcoded, default factory password is restored and the settings do get reset to defaults. Resetting to factory is the only way I can hope to restore the old configs, because otherwise I can't log in, so no way to restore settings. The lost password problem happens when I:
- factory reset the switch
- use the default factory password to log in so I can proceed to...
- restore the old configuration (Maintenance menu)
After I do this, the settings appear to be restored. Actually, I'm not quite sure, because I can't log in and examine the setting pages visually through the Prosafe utility interface, and therefore I can't edit anything. However, the previous behavior is apparently restored.
I'd at least need a way to read what those settings were, so I can reprogram them from scratch and hopefully edit them further to suit the needs of the growing network structure, and then save configuration again. The alternative is figuring out the whole LAN/VLAN setup through all the building and reprogram from scratch, with a lot of hit-and-miss experimentation.
Hi inky,
What I am thinking is that its possible that someone may have changed the password before the configuration was backed-up. Then, now that you have restored the back-up configuration file, you cannot login using the password that you usually know because someone has changed it. In relation to this, are you the only person who manages the network? If not, then kindly ask your colleagues if ever they have made password changes before.
Otherwise, the only procedure to do is to reconfigure everything from scratch which may take time.
