Hi markv & StephenB

I too and suffering this problem.

In this post I will reach out to two Netgear support people ( B_L & dingjs1421 ) that have been VERY helpful in the past in escalating issues such as these.

My Technical Details

Following a technical details on what I am seen

Firmware

My RN314 is running 6.10.5 Hotfix 1.

Problem Timeline

The log shows via the UI the following;

Oct 30, 2021 10:47:45 PM	System: Antivirus scanner definition file update failed due to download failure. Check your Internet connection.
Oct 29, 2021 10:46:42 PM	System: Antivirus scanner definition file was updated to 62.26337.

So on Oct 29, 2021 AV updated as expected and started failing on each update attempt as noted in the first log entry on Oct 30, 2021. Each failure to update shows a log entry like Oct 30, 2021.

Prior to Oct 30, 2021 AV was updating successfully for many many months.
All times above are UTC+11 (Australia)

Problem Diagnosis Info

To look into this problem I ran via SSH freshclam -v to gather some details and not the following (long output from the command below) which markv also sees in his update.

This look to me an issue that NETGEAR should be aware and is able to to give advice!

I hope that B_L or dingjs1421 or someone from Netgear is monitoring this topic.
