80mbs on 1GB package

[keiran7210]

Hi, 
Ive noticed a dramatic drop in speeds over the past few days. im on the 1GB package and running a speed test on a cabled device im only pulling off 90Mbps this has only started the past few days. 

I checked the routers Network log and there does seem to be alot of errors :

Check what this site shows:

https://samknows.com/realspeed/

There have been reported cases where the HUB 5 drops to 10/100 Ethernet speeds, which is a fault.

[jbrennand]

What cabled device is it?

A speed of just under 100 is usually due to one of these..

The ethernet cable has failed" causing it to drop to these speeds - get a new Cat6e cable and test with that.

Check the network card in the device is set to 1Gb and not dropped its setting to 100 - also check the drivers are up to date.

Is there a network switch in the "connection chain"? - if so... remove it and test again - theses do fail too.

Finally, go into the Hub settings and turn off/disable the wifi and also disconnect all ethernet cables from the Hub, except your one device. This ensures that NO other devices are connected

Then test speeds at https://speedtest.samknows.com/ - or https://www.speedtest.net/ - try on 2 different browsers - as Chrome sometimes gives odd results.

If they are still low – boot your device into 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.

Having the same issues. Tested on multiple devices, tried wifi from 2 phones, laptop, and ethernet from laptop. Getting as little as 0.5Mbps down with as much as 100Mbps up on the same speed-test.

Started for me about 3 days ago.

Almost certainly a QoS issue. Have an engineer booked, but given my experience with an ongoing transient disconnections issue, I don't have high hopes.

Virgin tend to send out engineers to just replace the hub and mark the issue "resolved" without asking the customer.

I suggest that you start the complaints process now, as early as possible. You have to give Virgin 8 weeks to resolve the issue (they won't) before you can escalate to the ombudsman.

The OP appears as mentioned above to have a network cable link that has de-rated to 100Mb/s or is crossing a Powerline adaptor or network switch that have 10/100 ports. The effect of this is a significant drop in Download rate and a smaller less obvious drop in Upload rates.

WorseISP - To stand a chance of getting help, create a new thread to report an unrelated problem.

Hi keiran7210, 

Thanks for taking the time to contact us via the Community. It's lovely having you on board with us in the Forums. ⭐

We're sorry to hear you are having issues with your broadband connection. 😔 Our diagnostics on your home network and Hub have not found any issues that could account for the issues you've mentioned. We've run a check on the overall area and there are no open faults which could be affecting you either. 

We need to concentrate on ensuring you are getting the correct speed via an ethernet cable first. Make sure you are plugged in to the hub using a Cat 6 cable and can you also check the network card on your laptop or PC to ensure this is 1GB. Once you have checked these, reboot your Laptop or PC into safe mode with networking and doing a speed test via speedtest.net. Please post the results back here 🙂

Thanks,
