Hello greyhound1racin

Have you tried to use another web browser when changing this setting.

hi darren thanks for your input, im using chrome ,have also opera and edge available, after posting qos problem, as i said spinning wheel, internet turned off, had to reset router to get internet back up , but to my suprise qos was setup, very strange, just tried opera to adjust bandwidth and nervously waited looked at spinning wheel, but reset it perfectly,so opera is working better, just out of curiosity, there is no option for upstream or downstream? any ideas ?? cheers.
