Very slow internet speef

Hi,

I currently have 100mb internet but I have just done a speed test and only seem to be getting 14mb

I have looked on other posts and one details about a low downstream power level dBmV. The level showing on my range from 13.53 to 15.47. I have no idea if this helps but I really need this sorting as it's been on going for a while now

Thank

Dan

Re: Very slow internet speef

Hi Dan

the recommended range for downstream power levels is -6 to +10 so yours sound like they are too high.  Could you please post all of the figures from the downstream and upstream pages of the router status screen, just so that I can get a fuller picture of the hub's status and confirm all the power levels.  Copy and post them (don't worry too much about formatting) or post screenshots, whichever you prefer.

Re: Very slow internet speef

Thanks, at least the upstream levels look OK but the downstream levels on all channels are far too high.  This will need an engineer visit to get the power levels adjusted.

You can call VM and try to book a visit or wait for the forum staff to pick up this thread (hopefully tomorrow) and they can help you book a visit.

A call back isn't possible with the forum team, but they should be in touch via this thread and a Private Message soon.

Re: Very slow internet speef

Hi Dan,

 

Thanks for taking the time to post on the community.

 

My apologies that you are experiencing slow broadband speeds. I know how frustrating this can be.

 

As Scott mentioned the downstream power levels are too high and I can arrange an engineer appointment to adjust these for you. I've sent you a PM (purple envelope icon, right corner) requesting some details. Once you have replied I can go ahead with the appointment.

 

There is also a high peak time traffic fault in your area which is causing slow speeds. Our networks team are investigating the problem and are improving bandwidth and performance to help with this issue. The reference number is F003463842 and with a review date of 11th January 2017.

 

Hope to hear from you soon

Sam
