SOLVED Strange Internet speeds

[jrj350]

This is just puzzling the pea-pick’en heck out of me.

I have an HP All-In-One Desktop computer. Windows 10 Home, version 10.0.19042 Build 19042

x64-based PC

Processor – Intel Core i7-7700T CPU @2.9 GHz

Memory – 12 GB

Sitting on my desk, right next to the above computer, I have an HP laptop. Windows 10 Home, version 10.0.19042 Build 19042

x64-based PC

Processor – Intel Core i7-855OU CPU @1.8 GHz

Memory – 8 GB

Here’s the catcher.

The desktop normally connects to the Internet with a connected LAN line.

The laptop normally connects to the Internet using WiFi connection.

When I run the Internet speed test, using my ISP as source, the Ping is 16 ms for each computer.

The upload speed is the same for both machines – 10 Mbps

But the download speed is completely different.

Desktop ≈ 90 Mbps

Laptop ≈ 228 Mbps

If I disconnect the LAN line from the desktop computer and connect to the WiFi, The down load speed drops to ≈ 30 Mbps. Upload remains at 10 Mbps.

If I connect the LAN line to the laptop, the download speed is ≈ 90Mbps. Upload remains at 10Mbps.

My contract with the ISP is up to 200 Mbps.

I then switched to OOKLA speed test and used an overseas ISP.

Desktop – Download – 90 Mbps Upload 10 Mbps

Laptop – Download – 150 Mbps Upload 10 Mbps

Any suggestions, ideas, clues, solutions?



Thanks for reading

Is the WiFi in the laptop using 802.11ac on a 5Ghz connection to the router?

Are the Lan and WiFi cards in both machines running the latest drivers?

What is your router?

 

[jrj350]

Yes to both of your questions.
The desktop computer has a choice of LAN line or WiFi. Of course it always chooses the LAN line.
The laptop computer has only the WiFi, WI-Fi 5 (802.11ac), 5 GHz.
Router - Sagecom F@ST 3686 V18 - IL

Did you check to make sure the nic on the desktop isnt hardcoded to 100 mbps for some reason ? All hardwired connections should be set as auto . Also to get a gigabit connection you have to make sure the cable is good as you need all 8 wires to connect at 1 gig other wise it will downgrade the speed which would be 100 mbps .

The cable was installed by the ISP technician so I am assuming it is the correct one. But I did substitute one of my own cables with no positive results.
Now for the nic. I did find a page that showed 100 mbps. If you would please take a peek at it.
