Webpages not loading correctly or not at all - all devices on Network!

[BenjyBoo]

This past week I've noticed, as well as others in my household on their devices parts of webpages not loading. Websites not loading at all without pressing F5 to refresh, or pictures not appearing, even some of the thumbnails on Netflix on the tablet not showing.

All temporarily solved by refreshing. I have rebooted the Virgin Media superhub 5 (which is in modem mode) and the tp-link Archer router, looked as if all was ok, then started happening again the following day and continues to be an issue on wired and wifi devices on my network.

Speed test is good Ping 23, 840 down and 100 up, Jitter 2.90ms.

What could be the problem?

Welcome. It sounds like DNS, on the face of it. What resolver (local software) and server (upstream provider, if any) are you using? Try changing them, restart the device(s) and test again.

Thank you so much for the welcome Rainmaker. Bit over my head "resolver" and "upstream provider", but at a guess I'd say on our wired PC and Wifi laptops it happens on both Chrome and Edge. And our DNS would be the standard Virgin Media use. We have always used a Virgin Media router in Modem Mode as the they can't handle many devices and the range of the Wifi is poor. And my Router is a TP Link Archer AX7800.
