Filters on the coaxial cable

[Rafiq-l]

Hi, 

don’t know if I’m using the right terminology, this filter at the end of my coaxial cable which then goes it to the back of modem, does it need to be fitted or can I do without it ?

if I’ve got them plugged in then I have no connection, I’ve had this problem for 2 days now and I’ve had to remove them for my internet to work.

anybody please let me know if I need to book an engineer.

Hi, can you copy and paste your upstream and downstream power levels from the hub settings pages?

[Rafiq-l]

How would I find that info ?

[Richw1982]

if you go to 192.168.0.1 under the password box there is an option for 'Check Router Status' if you click on that select downstream and then upstream.

Your upstream levels are out of spec, they should be 33-51 yours are around 53.  I assume the attenuators are wideband, so they affect downstream and upstream, this would bring your levels further out and would explain why you were getting no service.  I would leave them off for now, one of the forum team should be along soon and will be able to help you further.  I think you are going to require an engineer visit to investigate

Thank you 👍
