Self Install of Gig1 (SH5) - Do I still need the old 15dB Attenuator?

[Coatess]

So I had been on 500mb broadband for a while with the Super Hub 3 with little to no issues… Last month I received an email that I was being upgraded to the Gig1 Fiber as I’m a volt customer. However a SH5 would have to be sent out due to the SH3 not handling the new power. 

I never noticed before but I had always left a 15dB Attenuator on the end of the cable when changing out and installing a newer hub/router.

since upgrading I’ve had nothing but issues with my new speed, being completely honest it was better with the 500mb and the SH3! My WiFi now completely drops out randomly throughout the day….

I have removed the Attenuator and things seem to be ok for now but I’m not sure if it’ll cause any issues further down the line. If possible I’d like somebody to have a look for any issues that will be causing this drop In signal + also look at my down and up stream data to see if the Attenuator is still needed. 

Thanks in Advance.

Lets see the power levels

In your browser’s URL box type in http://192.168.0.1 (or http://192.168.100.1 - if in modem mode) (DONT click these links) - and hit return. No need to log in - just click on the “Router Status” icon/text at bottom-middle (Hub3/4/5) or top/right (SH’s) - of the Login page.

Then… Navigate to these “data pages” and just copy/paste the normal “Formatted Text” (not images) 3 FULL sets of data onto here – 2 tables from the Downstream and the 2 from the Upstream,

You really need a 10dbm forward path attenuator, any thing higher will be no good and it must be a forward path only one. You should really raise a fault with VM. 

[legacy1]

You likely be fine but to check you can setup a BQM

What do I say to them if you don’t mind me asking? 

[Tudor]

Just tell them the downstream power levels are too high.
