Very slow uploads and downloads

Hi,

I have the 1gig package and since yesterday I’ve been barely getting above 50Mbps down and 1 Mbps up, often a lot less making it unusable. 

Hub is in modem mode and Speedtests were run directly on the router (net gear Orbi)

Prior to this download speeds were always 700Mbps and uploads 50 Mbps

Re: Very slow uploads and downloads

this is a set of recent error logs, but they are similar to this ever since we got this hub.

3.1 downstream power level is too high. You will need an engineer visit to put this right. Best to ring VM on or just after 8am or alternatively you can wait here for a Virgin staff member to pick it up, typically between 5-10 days, sometimes sooner, sometimes later depending on how busy they are.

Re: Very slow uploads and downloads

Thanks for this.

I happen to have a 6db attenuator, so I’ve put that in.

 

do these levels look better?

Re: Very slow uploads and downloads

Thanks for your help. 

a hub reset + the attenuator seems to have done the job for now, hopefully it will continue to behave 😀
