I’m on the 200mb package with virgin, have a relatively standard set up at home. Two laptops, two smart phones, a TV and a PS4. Recently I’ve noticed a considerable drop in upload speed, it’s generally under 1mbps. I’m working from home full time and constantly on video calls - I regularly lose connection during meetings. I’ve done the standard hard reset on the router - no improvements.
there have been no recent changes to my set up, feels like something on the virgin side or maybe the router is shot.
Is it consistently bad at all times of the day? If it is good at off peak times, then I'm afraid it is network congestion and likely not an issue in your house. I've had the same problems myself - 100Mbps down all the time, crawling to less than 1.0 Mbps up a peak times.
