Internet drop out and some log errors - anything to worry about?

The internet dropped out, I went into the router and these logs were at the same time:

Any info on what this means?
Thanks

    See....

    https://community.virginmedia.com/t5/Networking-and-WiFi/Hub-status-data-understanding-network-log-messages/td-p/4716616

    Then post up the rest of the data like this.....

    Navigate to these “data pages” and just copy/paste the normal “Formatted Text” (not images) 3 FULL sets of data onto here – 2 tables from the Downstream, 2 from the Upstream, & the Network Logs pages. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again). If character limits are “exceeded” - just do two posts
