TX201 v1.0 2.5GbE slower than my onboard 1000mbps connection
I've installed a TX201 adaptor in my PC (the onboard is a 100/1000 port) thinking I'd take advantage of improved speed of my home network (TP-link Deco BE65, 2.5GbE ports) and internet connection (2000/2000 fibre connection), but doing a speed test now shows I'm now getting 450/450Mbps, whereas previously I was getting 950/700Mbps. This effect is visible by running speed tests one after the other and swapping the ethernet cable between the ports.
The TX201 is showing that the network is a 2.5GbE connection, so I'm not sure what's going on. Any suggestions?
I should note that I tried running a speed test on measurementlab and using the onboard ethernet I get retransmission rates <0.3%, but using the TX201 I get a retransmission rate >25%

Hi,
Is it directly connected to the main Deco?
Please also provide the following information for us to check:
1. The network topology.
2. The screenshots of the speed test results and the retransmission rate result.
3. The specification of your Ethernet cable and the computer operation system.

Hi Marvin - I'm having the exact same issue on my end.
I have a TX201(UN) v1.0 PCIe Network Adaptor. Driver = 1125.7.318.2022. PC is running Windows 11 latest. Cat 8 Ethernet cable.
The speed at my gateway is about 1.8GBps but only getting around 500-600MBps on the PC with this network card. I have a direct wired connection to the gateway.
Looking for some help as it seems somehow specific to this network adaptor.
Thanks!
Mike

Hi @MikeOz77,
If you're suffering the slow speed issue with the wired adapter, please check the link speed you can get by referring to this link:How to check the associated/link speed on a wired client:
1. If the link speed is normal, please uninstall the adapter, and reinstall again with the latest driver version.
2. If the link speed is abnormal:
a. Change to another cable (Cat6 or above).
b. Change to plug in a different LAN port on your router.
c. Make sure the router has the same specification, you can test with other devices.
