Consistently inconsistent speed - Surbiton

Hi,

We've been on Virgin media broadband for nearly 8 years and have consistently suffered broadband speed which has been all over the place. This has been particularly annoying in trying to listen to music (via Sonos), or watch anything through a streaming service (Prime etc). For example, I've run Speedtest 5 times today and the download speeds have been 9.46 / 214 / 0,78 / 7.76 / 1.11.

Please help!

From my router status: Downstream

Re: Consistently inconsistent speed - Surbiton

Are you seeing the same problems on ethernet cable connected devices as on wifi connected ones?

If its been like this for 8 years what have VM done to try and resolve the issue?

You are also missing downstream data ( with the RS error count columns) and post up the recent network logs.

Meanwhile, check all your coax connections are in nice and "finger" tight at the Hub and wall box and at any splitters/attenuators/etc with no “unterminated loose ends, and that the internal wiring is ok with no kinking or chaffing. Also check that all looks good with the outside cabling and wall box.

Re: Consistently inconsistent speed - Surbiton

The only ethernet connected devices we have are

1. Our mac which we rarely use. When we do, there are rarely problems.

2. A Sonos boost and

3. A MyCloud 1TB storage device.It struggles to talk to the Boost and vice versa on a regular basis. 

VM upgraded our hub a couple of years back but it's not really helped

Here is the additional info you asked for:

I don't seem to be able to cut and past the network log without getting error messages from the forum - any ideas?
