Hey there @vikrant82
You can opt out of the trial if you choose to. Simply send us a PM @FidoSolutions with the subject line "Fido Home Internet Firmware Trial", and we'll look into it
Sure thing @mads26! Welcome to the community.
We'll send you a PM shortly to help you get started with that.
Hey @mads26!
You should be able to disable it via "Wireless > basic settings" in the modem's settings.
Is this where you're going and it doesn't work? Is it blocked out or giving an error?
If so, then we can manually do it on our end. Please reach out to tech support and they can have it done!
Hey @athel10
Welcome to the Community
I'm not sure what you're referring to here, would it be possible to give us more info? Is that information you got through your VPN provider?
Also, are you using an additional router with the Hitron CGN3AMF Fido Wi-Fi Modem?
Let me know!
Hey @athel10,
VPNFilter primarily infects by taking advantage of known generic default credentials.
The default password used by the AMF is specific to our gateways and the Easy Connect flow then forces this password to become unique to the device so the AMF is not exposed to this vulnerability.
Hope this helps
