I’ve got ATT fiber but want to get the full benefit (I’m at 300 MBS down). What do you recommend?
Since AT&T provides the modem/router, I’d contact them first to see if there is a reason you are only getting 300 Mbps instead of full gigabit speeds. It may also be possible that your computer can only support those speeds, if for example, your wireless radio on your device can only run at 300 Mbps. Have you tested with multiple devices?
