Can you post your Hub status and logs? Someone should be spot if there is a problem Navigate to http://192.168.0.1 (or http://192.168.100.1 - if in modem mode) Don't log in! Click on 'router status' Copy/paste the data from each of the tabs. The forum software will remove the MAC addresses for you (you may need to click the 'post' button again).
If the hub needs constant reboots it's probably a power or noise issue. 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. 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. If we can identify a problem then the forum staff can book a technician for you. If the status data is good, we can move on to other possible causes.
