I recently upgraded my Slingshot 100/20 UFB plan to the Gigantic plan. After the upgrade, I tested both my Late2013 MBP and the desktop PC by plugging to the same ethernet port hardwired to the wall. The speed test indicated that the MBP worked perfectly fine by reaching 950/550mbps, but the PC only reached 450/400mbps max. As long as I can see, both devices showed the connection speed of 1Gbps.

I subsequently tested LAN speed by transferring large files from the PC to MBP over ethernet and the speed was constant 115MB/s, which was close to the theoretical maximum of gigabit ethernet.

The problem here is that the ethernet port of my PC is capable of transferring at the gigabit speed, but can only reach half of that speed when running internet speed test while the MBP has no such issue. I have a Samsung 860 EVO SSD installed as the system disk so there is no way it bottlenecks the throughput.

Does anyone have the same experience or any suggestions?

Cheers

Welles

I assume the desktop is Windows 10? Install the Speedtest app rather than using a browser and re-test.

How old is your PC.

The most common issue here is the network card being uncapable.

There are plenty of such threads on here. Your PC will be the bottleneck, and the first thing would be to see what newer network drivers may be available.

I'm pretty sure it was @freitasm who posted a few weeks ago about a newish HP machine that couldn't even get anywhere near Gigabit.

Correct. I had a HP laptop here, connected via ethernet and running Microsoft drivers (Windows 10). Speedtests were consistently around 200 Mbps. Installed the HP driver and instantly jumped to 600 Mbps. It will never get to gigabit because of the overall PC performance though.

Check the drivers.

This is a Windows issue...

Microsoft really messed up the QoS profiles in the later versions of Windows 10 to the point it just doesn't work correctly on fast internet connections anymore. Try booting into Ubuntu from the live disk and try doing a test with Firefox (you'll find it'll work fine).

I have not found a proper fix for it. I just gave up and went back to Linux on my desktop PC.

Thanks guys, the PC is a few years old with fourth gen. i3 CPU and H97 chipset Gigabyte motherboard. I did check the network driver at Gigabyte website and had it updated to the latest version for Windows 10, no fix though. I'm assuming that it's a Windows issue and hopefully gets fixed in future versions.

Make sure you are using the actual drivers from the motherboard vendor rather than the windows applied ones via update.
Your PC will be the bottleneck here, don't expect that hardware to do that much.. Maybe if you threw a SSD in there you might get a little more out of it.

I'd say it's most likely hardware incapable (reason: i3 cpu so likely other cheap components in the package), ie no amount of tweaking can get you the 1000Mbps.

HOWEVER, just in case it is a driver / OS issue ... you may persist knowing that it might lead to a dead end. Ie hardware.

Just installed Speedtest app for Windows and retested. Download speed boosted to 650Mbps and upload speed surprisingly went up to 1,400Mbps. Sounds nonsense.

I can get a 1GB speedtest on an ODroid C2 as per my signature and that's a tiny Single Board Computer the same size as a Raspberry Pi

It's your hardware rather than the broadband connection.

I know it's not the connection as my 5-year-old MacBook Pro easily reaches 1Gbps. Just trying to find out what happened to the PC.

I see you get 115MB/s (920 Mb/s) when transferring files from PC to MBP.
What do you get when you transfer files from MBP to PC?

Is the OS Windows 10 Home?

I tried transferring files from Mac to PC as well, speed varies from 110-130MB/s no issue.

The OS is Windows 10 Pro.
