Slow AT&T 1000 Internet speed problem
I got AT&T 1000 Internet + U-Verse installed today but ran into some strange problem that the tech couldn’t figure out. My AT&T modem diagnostic speed test shows 945 up/ 975 down from ONT to modem but hardwired Ethernet from the modem to MacBook only gets 450 up/550 down and wifi 200 up/213 down. The tech left without solving the problem. How do I solve this problem?
