Understanding Inssider

jasmin10

After a few weeks of very slow internet and sometimes the pafe even timing out and trying varies things to resolve I had a brainwave that I might be sharing a bandwith channel (don't know if this is something that might effect it) so thought I would download Inssider. Looking at the chart when scanning I was sharing my channel and have since changed it and it seems better although not made the problem disappear.

I would like to understand what lines mean. I know different colours are for different households but what they mean when they dip etc. I have looked at the manual you get with it but it dosent really show a lot.

Can someone explain it to me and as to how I can get the best out of it.
