I have a Hub 3, previously the 2 and I have to say I had no issues with that model but I have followed all the instructions given to me. Rebooted, replaced, check connections and nothing is improving my download speeds.
What do I need to do because I have run out of ideas.
Could you access your router using http://192.168.0.1/ or http://192.168.100.1 for modem mode . You shouldn't need log in, select the 'Check Router Status' option and paste your 'Downstream', 'Upstream', and 'Network Log' tabs? Please copy/paste this data as text, split between multiple posts (Sometimes you have to click 'Post' twice due to an error message).
Could you please create a BQM (Broadband Quality Monitor) here, and post the live link?
