WiFi не будет надежно подключаться при загрузке / перезагрузке сервера Ubuntu
Я использую Ubuntu Server 14.04.2 LTS и микро-беспроводной адаптер TP-LINK TL-WN725N.
У меня проблемы с автоматическим подключением при загрузке. Если я перезагружаюсь 10 раз, он может подключиться только 4-6 раз. Когда происходит сбой, я всегда могу заставить его соединиться с:
sudo ifdown wlan0
sudo ifup wlan0

Используйте следующую команду
sudo gedit /var/lib/NetworkManager/NetworkManager.state
make sure that these attributes are identical.
[main]
NetworkingEnabled=true
WirelessEnabled=true
WWANEnabled=true
Save the file and restart network manager as follows:
sudo service networkmanager restart
sudo service network restart
Use the following command if you want a specific adapter to be used and not the whole network manager to start
sudo ifconfig
For wireless connection use
sudo iwconfig
To get a list of all the adapters that you have on your machine with their names
sudo ifconfig wlan0 up
You can replace wlan0 with the adapter name that you have on your machine in case you have wireless connection.
sudo ifconfig eth0 up
You can replace eth0 with the adapter name that you have on your machine in case you have wired connection.

Это та же проблема с драйверами Realtek. Вы можете установить хороший драйвер с исправлениями. Запустите
sudo apt-get install git
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
и перезагрузитесь.
