Slow Gigapower after UVerse Voice Installed
I had Uverse phone installed yesterday, and the installer did a "hard reset" therefore everything to include my Wifi name (changed from default) was reset. Before he came I averaged 800 GBps, after he left we are maxing at 45MBps Wifi and 82MBps hardwired Ethernet Cat-6 on our 2016 Macbook Pro 802.11a and 2016 Mac Pro 802.11ac, 2 6s Plus iPhones, and 1 Samsung s7 edge. I attempting just to stress that the hardware is more than compatible for the network performance paid for and has worked flawlessly for the past 2 months. I know when the service was installed initially we disabled the iPv6; and made a few other changes. Please assist me in updating the router to pre-yesterday's installer's condition.
