What speeds do you get at >> SamKnows << with a direct connection using a Cat 5E or better ethernet cable between the Hub in Router Mode and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?
If possible can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.
Please post a 'Live Link' to your BQM on here straight away.
Instructions for posting BQM Live Link
Under your BQM graph are two links in red.
Click the lower link (Share Live Graph) then click generate.
Copy the text in the Direct Link box, beware, there may be more text than you can see.
On here click the Link icon (2 links chain to the left of the camera icon)
In the URL box paste the link you copied and in the ‘text to display’ box write My BQM then click OK - you can post the link straight away.
Type 192.168.0.1 (192.168.100.1 in Modem mode) into your browser URL bar and press enter.
Hub 2 & 3 When the page appears DO NOT LOG IN but click ‘Check Router Status’.
Hub 4 When the page appears LOG IN then Advanced Settings > Tools > Network Status.
Copy and paste the contents of the Downstream, Upstream, Configuration and Network Log tabs onto here, if you get a yellow / straw box warning click the Post button again. Use one post for each tab if you wish.
Okay. I will just copy and paste all the information.
If you get your broadband down the same cable from the street cabinet to the premises and then have exactly the same room and furniture make and layout with exactly the same connecting equipment there is a possibility that you have the same problem.
Other than that it becomes very confusing with too many people putting information up for checking and commenting on.
Type 192.168.0.1, Hub 3 didn;t give me an option to 'Check Router Status' only to login.
Can you do another test at >> SamKnows << with a direct connection using a Cat 5E or better ethernet cable between the Hub in Router Mode and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?
Then immediately after …
Can you Login to the Hub Settings and navigate to the Connected Devices page - what is the reported 'connection speed’ for the ethernet cable connected device you used for the speed test ?
