Interference

I am having issues with my internet again, getting very high spikes. When i did the virgin media website test it says i have interference. Last time when the engineer was here it was better but nothing changed in the house so i dont understand it. How can i get an engineer to solve this permanently?

Re: Interference

It doesn't have to be in the house, my VM Hub 3 Wi-Fi went into meltdown when the local authority / police CCTV camera on the lamppost adjacent to my house was used.

Re: Interference

What is your connection like using a direct connection with a Cat 5E or better ethernet cable between the Hub and a 1Gbs capable Pc/Mac/Chromebook ?

Re: Interference

If possible 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.

Please post a 'Live Link' to your BQM on here straight away.

Instructions for posting BQM Live 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: Interference

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 Advanced Settings > Tools > Network 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.

Re: Interference

Your Downstream Power Levels individually are all within spec but, the differential between the lowest at -0.2dBmV and the highest at +5.9dBmV 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 10 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'.
