Опять про скорость wi-fi
Форум — Linux-hardware
Прошу помощи у сообщества. Имею Linux debian 4.9.0-6-amd64 #1 SMP Debian 4.9.82-1+deb9u3 x86_64, поднята точка доступа на Realtek RTL8812AE 802.11ac PCIe(rev 01). Драйверы с гитхаба. На другой стороне самсунг А3 и Ubuntu 16 c Edimax 7392:b822. Hostapd собран с noscan. Скорость по воздуху показывает очень печальные результаты.
