Not getting full Gig1 speeds

Joining in

Switched from BT to Virgin around a week ago for the cheaper and faster download speed, had everything installed by a technician and everything looked fine until I did a speed test and was getting around 700mbps compared to the advertised 1130mbps, found out he installed a cat5 cable so swapped the cable to a cat8 and my speeds jumped to 950mbps which is better but still not the advertised 1130mbps which I definitely want.

I've tried different cables (cat5e and cat8), all get the same speeds. Tried different drivers on my PC, adapter settings, fully reset the hub, tightened coxial cable, updated motherboard BIOS, updated windows; everything I can think of and I still can't get the speeds advertised and yes the ethernet is in the 2.5gbps socket on the router.

My motherboard can pull 2.5Gbps (GIGABYTE X670 AORUS ELITE AX) I'm using a Cat8 ethernet cable directly to the Hub5, the speeds on show that my router is pulling 1110 and my device is pulling 1101, but a speed test on Ookla shows 951 and my steam download speed is around 110mb/s, so I don't really know what's going on here if I could even get the 1100~ displayed on the realspeed test I would be happy but if anyone has any ideas that would be great as I would love to get what I'm paying for...

If you do a speed test in safe mode with networking what speeds do you get?

Are you using an SSD or conventional hard drive for your steam storage?

Hi, same speeds while booted in safe with networking mode . Ive tried 2 different NVMe M.2 drives, one with 3600/4800mbs read and write speeds and one with 5500/7000mbs.

Up to speed

your pc ethernet actually connected at 2.5gb? seems like it might be stuck on 1gb?

Connection: Virgin FTTP Gig2 (XGSPON)


You'll need both a Hub 5 and a computer with a 2.4Gbs ethernet port, if you have the Hub 4 then sadly you'll only be able to get 950Mbs from the Hub via ethernet as the Hub 4 only has 1Gbs ports. If you have the Hub 5 then make sure your Cat8 is connected to port 4 as that's the only 2.5Gb port.

Try booting the PC with a live linux distro that has support for the Realtek 2.5Gb NIC on your motherboard.

It could be a driver conflict between the Hub 5 NIC and the Realtek NIC.

A Cat 6a cable is sufficient for your speeds btw, and a Cat 8 may be a hinderance.?

Some routes are limited for pulling speed then others


Yes it's connected to 2.5gbps port and my PC can handle that.

I have the Hub5 and my motherboard is capable of 2.5gbps, Cat8 cable is connected to the 2.5gbps port on the router also.
