to add what jbrennand said, would need to know this wired/wireless?, if its wireless can you test the speed wired.. 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..
