Xfinity/Comcast 2.5GB Cable

Netgate 4000 Router

TP-Link 2.5GB POE switches POE for Wi-FI APs and the desktops & laptops

 

I have a Generic desktop with Windows 11 install TX401 NIC. 

The driver was updated from Marvell site to Marvel AAQtion V3.1.1.1.0.zip

 

Everything worked great for months with average "2395MB down/ 299MB up"

 

UNTIL I shut off the computer.

 

Now it stays at less than "900MB down/295MB up". 

 

I have deleted the NIC driver and tried Marvell AQC108 - AQC107 

 

I have gone back to TP-Link CD whiuch is Version 3.1.8.0

All with same results of not getting back to average of 2300MB - 2400MB dowloads

 

Which driver should I use?

 

FYI: My wife has a Generic W10 with TX410 NIC and consistently gets "2398MB down/300MB up" and she requalalry turns her computer off

at night and has no problems when restarting.

 

Both computer have CAT6 cable to TP-Link 2.5GB switches. So I know the infrastructure is not a problem.

 

My desktop which now runs slow:

Windows 11 Professional (x64) Version 23H2 (build 22631.6199

MSI PRO B550M-VC WIFI (MS-7C95) 3.0

AMD Ryzen 7 5700G

64 GB RAM

The OS and applications are up to date

 

What am I missing?
