@ewhitey I'm confused as to why a) I'm not getting a decent speed e.g. always over say 850 and b. Why my readings are so widely variable?
Most likely because there's a noise or power level problem on your connection, these are usually easily resolved, and the forum staff can get that arranged if needed. I'd suggest you start a new post about this, because it's nigh on impossible to offer sensible advice and help to posters joining the back end of somebody else's thread.
In that post, basically the same text as you've put here, but if you can add replies with additional data as follows: Connect to the hub by clicking on this link http://192.168.0.1/ That should pull up the log in page for the hub if in router mode. But don't log in, just click on the link "Check router status"* That'll bring up a window with five tabs. Open the Downstream tab. Select all the text (Ctrl-A if using a keyboard), copy it (Ctrl-C), then paste it (Ctrl-V) into a reply here as TEXT not screenshots. Post that, do the same for the Upstream and Network log. You'll get an error message when you post the Network log, just click on "post" a second time. Then we can check for any obvious problems with power, noise or error counts.
* There was a bug with Hub 4 firmware that stopped that link working, I think it has now been fixed. If it still isn't working, navigate through the hub menus after logging in to the Admin section, and somewhere in there you'll find the hub's status pages.
