WiFi, не могущий найти сети на Ubuntu 18.04

Question 1

У меня есть ноутбук про Tbao Tbook, на котором у меня было Windows10, все работало просто великолепно. Я установил Ubuntu 18.04, и WiFi не работает. Это позволяет мне включить его и затем когда я иду для "Выбора Сети", не застревает в "никаких сетях" (я знаю, что существуют доступные сети). Я буду включать некоторые выводы, которые я попробовал в случае, если они полезны.

Question 2

У меня была подобная проблема с картой RTL8xxxxx на моем ноутбуке HP Stream... он только работал бы, если бы я был действительно близко к маршрутизатору (меньше затем 6 футов).

Я следовал инструкциям здесь https://askubuntu.com/a/722904/677112, и это зафиксировало его.

sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=2
echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/rtlbtcoex.conf

(замените rtl8723be своим точным названием драйвера, можно найти его путем ввода: lsmod | grep rtl)
