Assume a 65% account credit is comigng for every day I get 350Mb considering I'm paying for 1Gb?

Some of the Downstream power levels are above the -7 to 7 dBmV preferred range.

If the Hub is in Router mode try this : https://www.samknows.com/realspeed/

On a 1 Gb/s service the Hub is often not a limiting factor.

The real question is ...   Why is the device not drawing more than 350Mb/s ?

All the signal levels are within spec. 

What results do you get from https://www.samknows.com/realspeed/

Many thanks for the replies.

Unfortunately, I'm in modem mode with a Asus RT-AX86U managing my devices. For about a week, it's been at between 350-500Mb/s, varying by day. I've just set up a BQM on my connection so I'll see what comes from there over the next couple of days. On the weekend I'll be factory defaulting the Hub5 and trying with a laptop on the back of it. I know it's not my kit as I can move large files over my LAN (PC --> NAS) and it's flying.

Hi Pantsu, 

Thank you for reaching out to us here on the Community. 

I am sorry to hear of the issues you have faced with service. 

Unfortunately, whilst the Hub is in modem mode, we will not be able to run checks from here but if you have been able to set up your BQM, can you please post the live link? 

Thanks, 

[legacy1]

Your checks will show nothing wrong as will the BQM😞

[Gareth_L]

Hello Pantsu.

Thanks for your post.

Can I just ask if you have been able to factory reset the Hub?

If so, have you noticed any improvement?

In the Asus make sure QoS is disabled.

Also check in the 'Tools' section and make sure 'Flow Cache' is enabled.

I am running the Merlin firmware but make sure if you're running stock firmware your settings are like mine. If you have a WiFi 6 device trying doing a Fast.com test, I get 1.1Gbps or 940 over WiFi when I'm right next to the router.

Also, make you're using the 2.5Gb port on the Hub 5 and 2.5Gb WAN port on the Asus (GREEN)
