Unable to achieve 2.5Gbps on DEC750

[bhoriss]

Hi,
I searched all available forum posts and the internet to be sure I was not asking a question that was already answered so I hope i'm not wasting your time reading this.

I have just moved and changed ISP. My new ISP (telus) is charging me for 1.5Gbps over fibre. My setup looks like this:

Fiber to the home (tested today by technician, integrity seems good

to

ISP "fiber modem" (I seems to act as a modem and router with some firewall capabilities. I have my own firewall after it so I would love for it to be a modem and nothing else but it doesn't seem to present me with such option, eh...)

Model:    NH20A
Firmware Version:    v1.18.07 build02
Boot Code Version:    0.00.01
Hardware Version:    R01

This device has 4 RJ45 1Gbit/s ports and 1x RJ45 "10Gbit/s" port.

I connected a cat6cable (and tested other cat6 and cat5e short cables) from that 10Gbit/s port to my

DEC750 igb0 (and tried igb1 aswell) port which advertises
100/1000/2500Mbps capabilities.

Unfortunately, I am unable to get more than 1Gbits/s link speed

My first suspicion was:
The ISP provided box (NH20A) doesn't provide a 10/100/1000/2.5/5/10 capable port. I wasn't able to find the exact specs online, BUT, and here's the real kicker:

I have an optional device provided by TELUS. They use it as a "wifi booster". It's a


Boost3.0
Hardware version:    R02
Software version:    1.05.10 build06

This device has 3 RJ45 ports
one 10G
one 2.5G
one 1G.

When I plug things in this order:
ISP fiber to the home -> NH20A fiber port -> NH20A 10G RJ45 port -> cat6cable -> DEC750 igb0 port = I get 1000baseT auto-negociated
AND
when I plug:
ISP fiber to the home -> NH20A fiber port -> NH20A 10G RJ45 port -> cat6cable -> R02 (wifi booster device) 10G port = I get 10G speed to NH20A
R02 2.5G port -> cat6 cable -> DEC750 igb0 port = I get 1000baseT auto-negociated


BUT
when I plug:
ISP fiber to the home -> NH20A fiber port -> NH20A 10G RJ45 port -> cat6cable -> R02 (wifi booster device) 2.5G port = I get 2.5G speed to NH20A
R02 10G port -> cat6 cable -> DEC750 igb0 port = I get 1000baseT auto-negociated

so my conclusion is that the NH20A 10G port IS probably capable of 10/100/1000/2.5/5/10

Therefore, I am seeking your help to configured my DEC750 RJ45 2.5 capable ports to the correct speed in order to connect it to the NH20A box and get a 2.5G link.

Alternatively, I could maybe get 3x cat5e or cat6 cables from the 3x 1G ports between the DEC750 and the NH20A and aggregate them, but that seems janky, even for a noob like me!

(sorry for the wall of text, I wanted to be as clear and detailed as possible as I value your time)

Best regards,
Bhoriss
