Would need to check the signal levels if could go to http://192.168.0.1 or if using modem mode http://192.168.100.1 clicking router status top right or bottom of page depending on hub [no need to login - depending on hub] and if could copy/paste the downstream, upstream, network log, don't worry about the formatting we can easily read it.. try and avoid using screen shots..
if using a hub3 Visit http://192.168.0.1/ and login with your password (located on the bottom of your hub). In the menu on the left, navigate to Advanced Settings > Wireless > Wireless Signal. At the bottom of the page you will find the “Smart WiFi” section. Here tick the box labelled “Disable Channel Optimization” and apply the changes.
