FVS336G How do I change the certificate presented from 192.168.1.1 (Default admin)
I have the FVS336G installed to load balance between two internet providers (small office)
The admin page is SSL secured with a self signed NetGear CA certificate - After I add this certificate into my trusted list in Windows the browser complains about it using an obsolete cipher suite. I am concerned at some point these browsers are going to shut down access to this NetGear Firewall
I tried installing a self signed root CA cert and signing the FVS336G generated request with it - but it must only be used with VPN as it did not change the certificate used by the admin page.
Is there a way to update this admin certificate?
Or maybe a way to disable SSL - I have no interest in remote managing the FVS336G.
Is there a way to SSH into the firewall and swap out a certificate file or something?

PS: I have the latest firmware installed.
Hi woodd,
The FVS336Gv1 does not have a console port whereas both the FVS336Gv2 and FVS336Gv3 does have a console port. However, there is still no option to update the admin certificate nor swap out the certificate file via a console connection.
As per the CLI reference manual, it says on page 6: "You cannot generate and upload a certificate through the CLI..." You may access the CLI reference manual here.

Hi woodd,
I have checked that you have already contacted Netgear Chat Support and you have an FVS336Gv1 which is already End-Of-Life (both FVS336Gv2 and FVS336Gv3 are not yet EOL).
I don't think there is way to update the admin certificate nor swap out the certificate file via SSH.
Welcome to the community! :smileyhappy:

Well then -
- let me ask the same question about the FVS336GV3 (or V2).
Can you change the certificate used for the Admin page on the FVS336GV3?
I would like to know that I will not be forced into some perpetual hardware upgrades due to the loss of being able to connect with a browser.
Better yet, if access could optionally be in the clear for LAN connections.

I have a similar problem; I cannot load the sign in page at all 192.168.1.1 returns with a blank page "This connection for this site is not secure" and "192.168.1.1 uses an unsupported protocol" then "ERR_SSL_VERSION_OR_CIPHER_MISMATCH" Tried every browers I can think of tried turning off cookies cash even three different computers and nothing!
Similar problem, almost 10 years later - considering much more than an updated valid certificate would be required?
Hello@josephinelcajon
Unfortunately Netgear has ended the life of router FVS336G serval years ago. There are no longer firmware updates for it to support new versions of browsers protocol. When your browser’s TLS and SSL settings don’t align with what the server expects, you’ll see that error. But if you wish to have access to it's user interface there is a way but would require you to change configurations on browser. I found one example that might help is from the link below:
