I upgraded my broadband speed to 1 Gig in September 2022 and was provided with a new Hub 5. Using Ookla Speedtest on an ethernet connected device that has a 1 gig network interface, I get download speeds averaging between 250 and 350 Mbps and have never ever seen anything close to 1 Gig. I Spoke to a number of Virgin Media Technicians and each one of them say that they can see 1 Gig delivered to the hub and they have set some kind of monitoring that self fixes any issues. They seem to be pointing to possible issues on my internal devices.
Any experience with anything similar and advice appreciated.
Thank you for reaching back out, I was able to check your end and can see the SNR issue has cleared however I can see you haven't rebooted your Hub since, please unplug the Router from the power, leave 2 minutes then plug back in, once done please do another speed test Via SamKnowRealSpeed.com, this will show what is hitting the Router and will show if there are any further issues.
