upgraded to Gig1 and speeds so slow

Hi all upgraded to gig one and was sent the hub 4 since its arrived my speeds are around 300-350mbps its just nose dived I've tried to do samknows realspeed but it just says my device is offline?

these are specs from router hopefully someone more knowledgeable then me can shed some light as customer service said speeds are fine when clearly there not

Re: upgraded to Gig1 and speeds so slow

What speeds do you get on the 1gig official speed test site?.

Re: upgraded to Gig1 and speeds so slow

I am no Hub4 expert - but if its similar to the Hub3 I would say that the Upstream power levels are all too low and one has dropped qam to 32 - so it is struggling and will require a tech visit to rectify

Could try a pinhole reset to see if they get back into range
_________________________________________________

Do a Hub “pinhole reset” - make sure the 2 passwords on the Hub sticker are still there and legible first ! Disconnect any ethernet cables from the Hub (leave the coax connected), and then with the Hub still "switched on" throughout, press pin in firmly with paper clip/SIM tray tool or similar "thin thing" and hold it firmly for at least 60 seconds, release the pin, leave for 5’ to stabilise - dont manually switch it off at any time. Passwords will reset to those on the sticker. See if that sorts it.

my graph seems a complete mess as well 


Well that isn't looking so hot.

You could try a pinhole reset to see if the hub locks onto different channels, but it looks more like a fault in the area.

A reset would also reset all the stats as well, then you can copy and paste the data again here as you only showed

You should have 31 x 3.0 channels.

Re: upgraded to Gig1 and speeds so slow

The 3.0 Upstream power is a tad low, range is usually 34 to 51
