[SOLVED] Only 1 Gbps Networking speed on an advertised 2.5 Gbps network motherboard

[PeacefulTech]

Hi all,

I am using the motherboard: Asus ROG Strix B550 - F Gaming

It advertise to support 2.5 Gbps with the Intel (R) Ethernet Controller i115 - V. However, when I plugged in my internet cable, the speed only shows up as 1Gbps.

I am using a Cat 7 cable that supports 10 Gbps speed. I am using it to connect the motherboard Ethernet port directly into the Internet socket in the wall, with no internet switch or hub in between, so this shouldn't be an issue with Ethernet switches.

I have updated the driver to the latest version.

I have also tried forcing the connection speed to be "2.5 Gbps" by configuring a network adapter setting ("speed & duplex") in Windows control panel. I changed it from 'auto-negotiation', which is the default setting. This didn't do anything. The connection speed continued to show up as "1 Gbps".

Additionally, I have emailed my internet provider to ask whether this is an issue on their end. While I wait for their response, I am not sure who my internet provider can limit my Ethernet connection speed. I mean, they can give me lower internet speed, but my Ethernet connection speed should still show up as what the hardware I am using is configured to be, is that not so?

I am hoping to explore other trouble shooting options. What other things do you think I can try?

Thanks a lot guys.

Cheers.

Performance is dictated by the slowest device in the chain.

What is at the other end of that ethernet cable? A router?
That would also need to be "2.5 Gbps" to get that speed.

Hi thanks for your reply,

As mentioned, I connected the PC Ethernet socket direct to the Internet socket in the wall using the Cat7 cable, so it shouldn't be a problem caused by an intermediat Ethernet switch, hub, or router. However, I am not sure where the wire behind the internet port in the wall leads to. It is something I may have to ask the company that rent out the apartment to me. I will reach out to them and update here when they reply.

However, is it common for apartment buildings to have some sort of central internet switch where all the apartments within the building link their internet wires to? And perhaps that central switch has a limit, say I Gbps, on the internet speed?

Thanks again.

It IS dictated by whatever is at the other end of that cable in the wall. AND the actual cable in the wall.

PC -> Cat7 -> wall plate....then...we don't know.
Everything after your Cat7 cable needs to be capable of that "2.5 Gbps" speed. Everything up to and including the router port.

It does no good if your firehose size "2.5 Gbps" pipe is connected to a "1 Gbps" garden hose.
And if this is NOT your equipment, it is almost certainly just standard gigabit throughout.

In addition, your speed connected to the outside world is dictated by whatever you pay the ISP for.
Highly unlikely that is more than 1Gbps.
