Speeds dropping frequently

Hi,

been having issues with my 250mb package recently. On rare occasions it will be working at full speeds but more often than not the speed will be alot lower, as of late frequently dropping to 10-20mbps.

Was wondering if the power levels might be an issue as i did the self install without an engineer.

Generally looks okay to me except that downstream channels 1-3 have gone Awol.

Maybe try a 30 second pinhole reset of the hub and try again. 

I'm not a Very Insightful Person (just a little bit, sometimes). I don't work for Virgin Media (but then nor do any of the offshore customer service agents).

The channel number and the Channel ID are, well, virtual numbers and in themselves don't mean anything. If you count how many downstream channels there are, you'll see the expected 31. 

So, in that respect it's fine

Hello Phasmatic, thanks for joining our help forums and welcome to the VM community.

Sorry to see you've been experiencing issues with your hub and service speeds, we'd love to help with this.

Could you please advise if the slow speed issue is on an ethernet connected device or over wireless?
Also, please visit here for more on our service speed tiers and minimum guaranteed speeds on wired - does the speed on a wired connection fall below what's advertised on our page?

If so, would you be able to remove all 3rd party equipment and devices connected (if any) and run a speed test as below:

a) while on router mode (over ethernet, all other devices and any 3rd party equipment disconnected)

b) while on modem mode

c) while on safe mode

Check and let us know what values you're getting and where we are with this, happy to assist.
