Accurately Test Speed

Dialled in

I have posted on here before about the speeds I get and I have recently taken out an O2 mobile phone contract so I qualify for Volt and my speed has been increased to 1gb.

I connected directly into my laptop using the USB-C port and an Ethernet adapter and Sam Knows.

The speeds I recorded were around 350mb and when I used Sam Knows via WiFi I was getting about 450mb so less than half of what is predicted/expected.

Virgin have told me my equipment is all working correctly and they have no issues with the fibre optic connection so why are my speeds so slow?

Has anyone else experienced similar issues or is there a known reason why my speeds are so way off?

If I replied previously I would have asked you to test speeds like the below. Note the links at the end of the post.....

As you expect >100Mbps then connect a 1GB enabled computer/laptop, with up to date drivers, via a NEW and working Cat5e/6a ethernet cable, directly to the Hub which you have put into “modem mode”

( ).

This ensures that NO other devices are connected

Test speeds at - try on 2 different browsers as Chrome sometimes gives odd results.

If they are still low – boot your device into Windows safe+networking mode - to disable any potentially interfering software - and try again.
There are many posts on here (I have a list of ~30!) where QoS software, anti-virus, unknown/flaky software, old network card drivers, corrupted browsers, bad cables or other connected devices are limiting speeds on tests.

Report back what that gets. For examples of why... see message 7 in the first thread and 9 in in the second and 3 in the third


I do not work for VM. My services: HD TV on VIP (+ Sky Sports & Movies & BT sport), x3 V6 boxes (1 wired, 2 on WiFi) Hub5 in modem mode with Apple Airport Extreme Router +2 Airport Express's. On Volt 350Mbps, Talk Anytime Phone, x2 Mobile SIM only iPhones.

Might seem like a stupid question to you but how do I tell if my laptop is 1GB enabled.

Hi @Stanl 

You don;t say what type of laptop you have eg Windows, Chrome IOS, however the screenshot below how to check using Windows.

Press the Winows key and type in ethernet. Then select ethernet settings. Then change adapter settings. Double click Internet and it should show the speed as indicated on the left of the picture below.

If you need to change it change it, click Properties followed by Configure then scroll down as shown on the right and set the value to 1.0 Gbps Full Duplex.
