Netgear network speeds
So I have a home network with a mix of Win7 (Pro and Ultimate) and Win10 (Pro and LTSB) machines, desktops, towers, NUC and SFF laptops and tablets. Both wired and wireless.
The Netgear Nighthawk XR1000 router sits in the centrally located kitchen with an Ethernet connection to the NUC from the router switch. (6ft. Cat7 cable) This unit can consistently achieve 940Mbps speed tests to a specific Spectrum speedtest site.
The router also has a switched connection to my office with a 60 ft. Cat 6a cable to a 1Gbps brand new GS108Ev3 Netgear managed switch (supports Jumbo Packets) and 20 ft. Cat 6a patch cables to each of the three other machines there.
All Speedtests are done to the same site with Ookla speedtest.exe software at random intervals, and this software keeps a csv record. This is not a browser web based speedtest.
Laptop One, consistently gets in the 400Mbps plus range. It has a 1Gbps USB3 Express card to Ethernet adapter. The network adapter in the docking station on this unit is connected to a printer on a different IP subnet.
Laptop Two, is an identical model to laptop one with the same model Ethernet adapter. It consistently gets no more or less than 250Mbps tests. Both from the docking station nic and the usb adapter nic.
Desktop Three, consistently gets 200 to 300 Mbps readings. Although there will be an occasional 400-600Mbps reading. This machine has two Nic’s down on the motherboard.
- Intel 82579LM Gigabit Network Connection, for Printer and NAS
- Intel 82574L Gigabit Network Connection, for Internet
These three machines have a mix of AV and Firewall, both ZoneAlarm and MSE. Turning ZA on and off seems to make no difference at all. Nothing unusual about the software loads, MS Office, Norton Ghost, Adobe, Brave and/or Firefox, etc.
Jumbo packets and forced 1Gbps full duplex have been enforced on all network adapters.
I am looking to standardize the results from these three machines, with the control unit: the NUC. Since Ethernet is capable of supporting 940Mbps and 990Mbps with Jumbo packets, I want this.
All network adapter drivers have been updated to the most current available.
I do not believe that this is accountable to the speedtest server, as the NUC gets consistent test results, and I believe that this server has multiple 1Gbps connections or a 10Gbps connection to the Internet.
What have I missed?
Ideas?

what happens if you direct connect one of them directly to the laptop with no extended run/switch? Just a 6ft cable between router-computer.
What speeds do you get?
That's where I'd start. Simple router/device.
Thanks for your response.
Let me now add some new complexity, to perhaps bring some clarity.
I put a Samsung tablet next to the NUC.
The NUC with an Intel Ethernet Connection I218-V got 768Mbps
With the Samsung tablet with the factory dock Realtek PCIe GBE Family Controller I got 319Mbps
Switched the router switch ports, no effect on either
I did not yet switch the Cat7 cables between them.
Switched to a USB to a Ethernet adapter on the tablet and no effect
QOS and VPN are OFF in the router, running newest firmware which is older than I would like.
Router MTU is set to the Max (default) on the router at 1500
Am going to try a SuperSpeed Express Card in the slower laptop to see what that brings. Low expectations here.
Each of these three machines get an ipconfig/release and renew daily via a utility I have. It's an OpSec thing.
Do I need to somehow rebuild TCP/IP on the slow machines? netsh int ip rese?
PS. I envy your fiber.
Speeds I saw when I had my XR online last year:
thanks for the info.
