Hi, we got an upgrade to Gig1 last week but we aren't getting Gig1 speeds.
Samknows reports speeds to the Super Hub 4 as perfect, in excess of 1000mbps but plugging in a device to ethernet (correct cable tested 5E and 2 different Cat6, 1gbps enabled on the NIC) it sits between 300 and 600mbps.
This was even worse when the hub was still in router mode. Since been switched to modem mode to use with Netgear router, but the fact of the matter is, ethernet connections are nowhere near 1gbps as I would expect.
We upgraded from 200mbps so could this be a power level issue? Barely getting double the speed. Speed tests zoom between 400 to 800 and then after the initial spike, lower down during the test closer to the 300/400 mbps mark. To be clear, this is ethernet.

Levels all look okay at the moment. Have you run a speed test at RealSpeed - SamKnows directly connected to the Hub via a known good Cat 6 cable, using a gigabit enabled device, e.g. laptop? If not, please do so and let us know the result.

Hi there, thanks for your response.
All speed tests have been performed using SamKnows.
Samknows reports speeds TO the Super Hub 4 as perfect, in excess of 1000mbps but plugging in a device to ethernet port 1, port 2, port 3, whatever (correct cable tested 5E and 2 different Cat6, 1gbps enabled on the NIC) it sits between 300 and 600mbps when running samknows.com/realspeed. For example, saw an initial spike of 800mbps before it quickly shotdown to the 300/400 mark and settled there.
I mean, I can buy even more cables? I don't have a cable tester unfortunately, but does the fact that it managed to spike up 800mbps for a second not mean that the cable is as advertised?
It's now been tested with 3 different brands of Cat6 across across 5 cables and 2 different brands of Cat5e cables for 7 different 1gbps cables and 2 different devices, making sure 1gbps is enabled on the device's LAN card.

the cables would seem ok - are all the tests to the same wired device - if so try a test to that device with the hum in modem mode - if its still slow leave the hub in modem mode and put the pc into safe mode with networking and try that
you could also try a full reset of the hub

Hi Tony, when you say a full reset of the hub, do you mean a factory reset or just a power cycle?
I will indeed try safe mode with networking, but I have tried 2 different windows devices.
both are worth trying - start with a power cycle and if that does nothing then a full reset - thats a last resort as it will set everything back to default - so you need to set things back to how you want them - passwords etc if you do reset it

Hi @mcons,
Apologies for the delayed response here, and sorry to hear you've been having some connection speed issues lately.
Are these ongoing today? If so, has the advice that @-tony- has offered helped at all?
Thanks,

Hi, apologies for the radio silence.
So plugged in direct to the modem, restarting, safe mode with networking etc. it's the same scenario.
We'll do a speed test and it will initially shoot up to 800 or so mbps and then slowly crawl down during the test and sit around 500mbps.
To be honest, I haven't tried a factory reset of the hub, but nothing has changed from the default settings anyway. I can try this today though if you think it might help.
