Speed has been variable, but very slow since Christmas. Connection via ethernet.

Seems to be a Network Issue

Your downstream power levels need adjusting, with an engineer visit, as they are out of spec (-6 to +10 is in spec, 0dBmV optimal).

SNR looks a little 'off' as well.

You need to post the rest of the stats, i.e. power levels, both Upstream and Downstream and include the Pre and PostRS errors.

Also setup a BQM for monitoring, www.thinkbroadband.com/ping

Once done we can comment.

Hi StevieBee,

Thanks for posting on our community forums. Sorry to hear that you're currently experiencing issues with our internet services, we understand the frustration and disruption this causes. 

As our valued member @carl_pearce has pointed out, your upstream and downstream power levels are out of specification.

I have performed quick routine diagnostics check for you and can see this is indeed an issue which we will need to address with a technicians visit for you.

So, I can get this arranged, I will pop you over a private message to take some details from you. 

Please click on the purple envelope to accept the chat.

Kind regards Jodi.

Just to confirm, there will be no charge for this visit unless:

The technician diagnoses the fault 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 that someone over the age of 18 is at the property for the time the engineer is there. If the appointment is unsuitable or if anyone living at your property has tested positive for Coronavirus, has been asked to self-isolate or has flu-like symptoms then please reschedule the appointment on the same link.

Lets us know how the appointment goes. 
Kind regards Jodi.

Visit was successful and power levels now within spec.

However, download speeds are still not achieving the minimum contracted levels - 80-90 Mbps, when they should be at least 181 Mbps for a M350 Contract.

Glad to hear the visit went well @StevieBee, just to confirm are you seeing these download issues on both wired and wireless connections?

 

Regards

 

Nathan
