Sudden drop in SamKnows RealSpeed to router

[betaspin]

https://samknows.com/realspeed/ tests to my Hub 5x usually show download speeds of 1140-1142 Mbps (I am on the Gig1 Full Fibre package). However, since yesterday evening the tests to the hub struggle to achieve more than 250-300 Mbps. I have rebooted the hub a couple of times, including power off/on, but the realspeed downloads to the hub remain slow. I have spoken to Virginmedia support who could not notice anything on their end. Fast.com speeds have dropped from the usual >1Gbps to about 500 Mbps, and https://www.thinkbroadband.com/speedtest is pitiful, 35 Mbps single thread and 230 Mbps multithreaded. Any suggestions on what might be wrong and how to proceed (and convince Virginmedia to have a proper look at this) would be much appreciated.

Post a screen shot of the result from Realspeed with "Run full test" enabled to demonstrate the issue.

Here it comes.

Having exactly the same issue! Although, I noticed my speeds started to drop about 2 weeks ago and I would loose approx. 100Mbps a day. My last RealSpeed test was 252 down.

In my case it happened suddenly yesterday evening. What made me run a realspeed test was that the next in a series of Netflix episodes I was watching started in very low resolution. Have you tried the thinkbroadband tests and are you getting very low download speeds there, as well?

[AidyM]

Just tried thinkbroadband - not good! (34.6Mbps single, 260Mbps) and even my upload was poor.

Clearly, we have very much the same problem.

Not surprisingly, the download speed from https://www.virginmedia.com/broadband/speed-test is also rather underwhelming... This is more than twice lower than the minimum guaranteed download speed of 565 Mbps shown on https://www.virginmedia.com/broadband/our-speeds-explained. I hope that one of the VM representatives here could look into this.

Have you manage to get this fixed?

No, in fact, it is getting worse, see below for the realspeed test this morning. As I find it unusual that a VM staff member has not looked into this problem so far, yesterday I took the liberty of sending a private message to one of them, providing links to both of our threads, but was reproached for doing so.
