TNAS 4.2.17-2110301418-P1.18 shows Internet as Disconnected

Hello

My TNAS F4-210 is currently running TOS version 4.2.17-2110301418-P1.18.

The system information page shows the Internet to be reporting as being Disconnected, as per screenshot SystemInformation_20220112.png. Because of this, I'm unable to update my unit to the latest version of TOS, which the unit itself says is TOS 4.2.20.

Per screenshot NetworkInterface_20220112.png, the default gateway is configured as 192.168.0.1 which matches the IP address of my router. I haven't made any changes to the configuration of my router recently, therefore I don't believe anything has been amended that would have stopped the F4-210 from accessing the internet when it did previously.

Per the recent notification of malware attacks on these units, I have disabled Telnet and SSH access, even across my local network. I have also disabled UPnP discovery.

Is this a problem arising from the currently-installed version of the OS? If so, where can I go to download the files necessary to do a manual update to get me to 4.4.20?

Thanks In Anticipation

Hello, your TNAS shows that it cannot connect to the network because DNS is not configured in the network settings. Please set DNS to: 8.8.8.8 and try to re-enter the system.
You can also download the 4.2.20 update package from the official website, and manually update the system to the 4.2.20 version in Control Panel > Update and Restore.

I changed the DNS as directed, and then tried to run the Online Update but it reported that the online update failed and that I should check the network or use the manual update.

Can you give me a link to the location for the 4.2.20 update from the official website?
