Splitter causing speed issues?

Since engineer install of my M500 service (now migrated to M600) back in March I've been getting my advertised upload speed but in most cases struggled to get above 220mbps download speed via direct ethernet connection to the hub 3. Wifi speeds are adequate at this time as most of my equipment is ethernet.

This falls short of the minimum speed guarantee. I've reached out to VM but while I'm waiting a response I wondered if the splitter that was installed (I have the TV service too) could be causing an issue? 

Does the splitter cause degradation in download speeds?

Re: Splitter causing speed issues?

Can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.

Post a 'Live Link' to your BQM on here.

Instructions for posting BQM Link

Under your BQM graph are two links in red.

Click the lower link (Share Live Graph) then click generate.

Copy the text in the Direct Link box, beware, there may be more text than you can see.

On here click the Link icon (2 links chain to the left of the camera icon)

In the URL box paste the link you copied and in the ‘text to display’ box write My BQM then click OK - you can post the link straight away.

Re: Splitter causing speed issues?

Can you please

Type 192.168.0.1 (192.168.100.1 in Modem mode) into your browser URL bar and press enter. 

Hub 2 & 3 When the page appears DO NOT LOG IN but click ‘Check Router Status’.

Hub 4 When the page appears LOG IN then click ‘Check Router Status’.

Copy and paste the contents of the Downstream, Upstream, Configuration and Network Log tabs onto here, if you get a yellow / straw box warning click the Post button again. Use one post for each tab if you wish.

Please do not use screen grabs.

A Guru will be along soon to decipher the info.

Your Downstream Power Levels individually are all within spec but, the differential between the lowest at -1.4dBmV and the highest at +3.2dBmv is too great.

This will need an engineer to put right.

You can either call in (08:00 is the best time) or wait on here for a few days (6 to 7 days average) until one of the VM Forum Staff comes along.

If you wait on here Do Not bump the thread it will put it further down the VM 'to do list'.
