Speed drop

Hello,

I had 1Gig installed on the 11th December 2021 and everything was perfect until last week, for the last week my download speed never goes past 90 Mbps. if I reboot my hub4 modem and my router the speed will be perfect 600-900 Mbps but 50-10 minutes later the speed drops again, these speed tests have been recorded from speedtest.net (Web and CLI) Sam Knows (speedtest.samknows.com) and nperf (nperf.com).

I have tested the download speed via wifi and ethernet on BOTH the router and modem (in router mode) but I get the same results.

Any help will be appreciated.

Re: Speed drop

Your BQM is a mess and the 3.1 DS Channel should be 4096 QAM, and the power is also too low, should be between -6 and +10 .

You will need a VM technician to sort this out.

Either phone in or wait here a day or two for a VM Mod to pick this up.

I'm a Very Insightful Person, I'm here to share knowledge, I don't work for Virgin Media. Learn more

Re: Speed drop

Hi @Priingleton,

Welcome back to our Community Forums! Thank you for your post, and I'm sorry to hear that you're experiencing some ongoing speed issues with your broadband at the moment! I can understand how frustrating this is. 

I have been able to locate your account and I can see that your downstream power levels are not looking so great at the moment. As @Adduxi stated, you will need a technician appointment. I will send you a Private Message to discuss this further. Please keep an eye out for a purple envelope at the top right corner of your Forum page. I will be in touch soon.

Thank you.

Re: Speed drop

Hi @Priingleton,

Thank you for coming back to me via private message and confirming your details. I have now booked you a technician visit for your speed issue – you can check and amend the date and time via the online account.

There will be no charge for this visit unless:
•    The technician diagnoses the faults as not being caused by our network/equipment 
•    The technician discovers that the fault or problem relates to your equipment
•    The technician discovers that the fault or problem relates to any system that we are not responsible for
The technician will confirm during their visit if any of these instances apply, and if so, a £25 charge will be applied to your account. 
Please ensure there is someone over the age of 18 present at the time of the visit. If you need to change or cancel your appointment you can do this online or via the MyVM app by 4pm the day before the appointment.
If you do miss an agreed appointment for any reason, a £25 missed appointment charge will be applied to your account on the day of the appointment.

Thank you.

Re: Speed drop

@Paulina_Z,

 

that's perfect, thank you, are you able to make sure the engineer knows what the issue is? as every time I have an engineer out, they don't know what's wrong and they don't fix anything.

 

Many thanks
