Intel I225-V Ethernet Adapter capped at 100Mbps

[NICommunicate]

I just purchased an ASUS ROG Strix B550-A Gaming motherboard with the I225-V network card and I'm experiencing  a 100Mbps speed limitation. I have tried the suggestions from other threads and still yielded the same results of 100Mbps being my throughput cap. Please advice.

Hello NICommunicate,

Thank you for posting in Intel Ethernet Communities. 

Kindly provide the following information that would help in checking your query. 

1. When you mentioned capped at 100mbps, can you share if this is when you run a speed test or are you seeing the 100mbps from your Device manager?

2. What is the guaranteed speed rate from your Internet Service Provided (ISP)?

3. Double check the established connection speed in the settings of your system: Network and Internet Settings; View your Network Properties and scroll down to Link speed (Receive/Transmit).

4. When was the issue first encountered?

5. Operating System used?

7. Can you share the troubleshooting steps done when you mentioned 'I have tried the suggestions from other threads'

8. Cable type used?

Awaiting to your reply. 

We will follow up after 3 business days in case we don't hear from you.

1. When you mentioned capped at 100mbps, can you share if this is when you run a speed test or are you seeing the 100mbps from your Device manager? The is when I run a speed test, when I look at the device in the device manager, and my 1Gbps switch has a LED indicator that tells me if the device is a 100Mbps or 1Gbps. It is also indicating it’s a 100Mbps device using that port

2. What is the guaranteed speed rate from your Internet Service Provided (ISP)? My ISP guarantees 400Mbps. I have verified this speed using my laptop and my wife’s desktop and laptop.

3. Double check the established connection speed in the settings of your system: Network and Internet Settings; View your Network Properties and scroll down to Link speed (Receive/Transmit). The connection speed was set to auto negotiate and the system establish a 100Mbps rate. Even when changing it to 1Gbps it then lost connection. I then changed it to 2.5Gbps and it still didn’t work. It only worked after dropping it back down to 100Mbps or setting it to auto negotiate.

4. When was the issue first encountered? This error occurred fresh out the box last week.

5. Operating System used? Windows 10 Pro

7. Can you share the troubleshooting steps done when you mentioned 'I have tried the suggestions from other threads' (I’ve tried installing the drivers provided with the motherboard. I’ve tried downloading the most recent drives from the ASUS website for that specific NIC card. I’ve tried downloading the drives for that specific NIC from the INTEL site. I’ve tried downloading the Intel troubleshooting shooting software. I’ve tried changing the transfer speed withing the OS (receive/transmit). I’ve tried using three different cables, CAT5 and CAT6. I’ve even upgraded the OS from Windows 10 Home to Pro (I was going to do that anyway)

8. Cable type used? Monoprice CAT6 cable wired using TIA 568B standard connected to a TRENDnet TEG-S82g 1Gbps unmanaged switch. I have five other devices connected to this switch and they’re all running at 1Gbps so that said it can’t be the switch. And the cable has a capacity of 10Gbps so that shouldn’t be the issue either.

Hello NICommunicate,

Thank you for time you have taken to provide us with all of the details. 

Just to clarify on item number 3, does this mean that the steps from article 'Intel® Ethernet Connection I219-V Unable to Reach Gigabit Speed' helped fixing the issue but after reboot, the issue came back? Or the Intel® Ethernet Controller I225-V didn't worked after the steps done? If the issue came back or another issue was encountered, can you please share more details regarding the issue for us to further investigate. 

Hoping to hear from you soon.

Oh no, it didn't fix it. It ran correctly for all of five minutes then reverted back to 100Mbps and since that moment I've not once seen it touch 1Gbps even for a second.
