Question 500Mbps fibre connection but wife's laptop with Gigabit adapter only gets 300Mbps at best ?

[JeremyP99]

Hi,

We have 500Mbps fibre broadband. To my Shuttle SH570R8 PC, hard wired to ethernet card, I often get high 500s, down and up
To a PC downstairs (MS Surface Pro 4), connected to a USB 3.0 Gigabit adapter, 500 every time, down and up,

But on my wife's laptop, connected to a USB 3.0 Gigabit adapter, right by the router, she only gets 320Mbps down at best, and approx 250 up.

What can I do to enable her to get the full 500Mbps on her laptop?

Speed & Duplex set to 1.0Gbps Full Duplex on the adapter
Windows 10, up to date.

Thanks in advance

Is very strange I assume you are using exactly the same USB ethernet device on the pc that works and the one that doesn't.

Be very sure that you are not connecting via wifi it is not uncommon to get 300mbps on wifi close to the router. A normal ethernet port tends to override the wifi if you have both connected but I am not sure about a USB and even less sure when it is a laptop.

It is more of a desktop computer thing but many times there is some so called "gamer" networks software bundled with the bloatware on motherboards and video cards. asus is the worst offender. You want to unistall any software that claims to favor one kind of traffic over another or do any kind of QOS. CFOSSPEED is a common name.

It appears the device is running at USB3 speed so it should be able to run gigabit. There is considerably more cpu load using a USB adapter but modern cpu tend to be more than powerful enough. It though is possible to get stalls and lag if you were to have something else running that was using all the cpu.

Thanks - definitely not a WiFi connection. And no crap on the laptop; it belonged to my wife's brother who is a super geek, so there's no nonsense on it at all, and my wife really only uses it for the web and some email. I know CfosSpeed as I used it way back, and that is definitely not installed (I too was a techie for 25 years, now retired, pretty good with Windows). Yes - I'm confused as well; I have on other unused USB 3 Gigabit adapter, and have swapped all round; no difference, so it's not the adapters, rather something on the laptop is all I can assume. Weird.

Reset the network.

Although I suspect it will do the same thing try to use a tool like IPERF to transfer data between your main ethenet connected pc and the suspect laptop. You could I guess use file sharing and copy files also. If IPERF has issues it has to be at almost a driver level it is such a simple tool. things like speedtest can be browser or even disk issues.

Well I think I've done that, rebooted the router etc. etc. but will try again

Will give it a go. I do have an FTP server on my PC, which I sometimes use to transfer whatever from my wife's laptop. But FTP speeds are always pretty low, as are straight file transfers over the network.

Is it possible the adapter was plugged into a USB 2.0 port? Or probably 3.0 port malfunctioned.

ok. Running fine on my PC as server; on my wife's the client command iperf3 -c PC-A did nothing other than display all the possible parameters

You take the example to literal. You need the IP of the other machine not "PC-A"

Ah. OK. In the meantime I downloaded and ran TCP Optimizer, which fixed the speeds; speedtest to Velox Communications London (who seem to provide the best speed) gave c560Mbps down and 380 up. So will leave it at that! Thanks

 

[bill001g]

That is a very risky tool to use. It changes many things at the same time and if it makes things worse it is hard to undo. Better off doing it manually most times.
