i have been paying for the fastest broadband however only getting 12mbs line , 8 months ago i started to the process of fixing it , online bot chat is shocking , and makes me wait 8 hours and i keep getting cut off when i phone from a call centre .
is that speed what you get over wifi or a wired connection? if wifi, what do you get when connected to the hub directly via an ethernet cable?
will need some more information about your hub - can you do the below;
set up a BQM - once set up, find the Live Graph and click "Create Sharing Link" - post that back here.
Next, browse to your hub on http://192.168.0.1 - don't log in, click Router Status - copy/paste the tables from the Upstream, Downstream and Network Log tabs back to this thread - you'll need multiple posts for this, the info wont all fit into a single one..
