Беспроводное соединение падает на Intel Centrino 6235

Я нахожусь в сети Wi-Fi в школе, у которой есть безопасный доступ, и я использую это уже несколько месяцев, но проблема началась несколько дней назад. Каждые 3-5 минут я теряю доступ в интернет, но сохраняю подключение к сети. Я работаю в блоке кабинета, и другие люди вокруг меня имеют тот же компьютер и не имеют такой же проблемы. Мое оборудование:

02:00.0 Network controller [0280]: Intel Corporation Centrino Advanced-N 6235 [8086:088e] (rev 24)      

Журнал dmesg показывает попытки повторного подключения много раз:

Я уже пытался отключить 802.11N, как упоминалось в Intel Centrino Centrino Advanced. -N 6235 слабый беспроводной прием или даже выполнение его вручную, например:

sudo rmmod iwlwifi   
sudo modprobe iwlwifi 11n_disable=1

Оба не работали. Я даже попробовал отключить его следующим образом:

sudo iwconfig wlan0 power off

Также попытался отключить IPv6:

echo "net.ipv6.conf.all.disable_ipv6 = 1" | sudo tee -a  /etc/sysctl.conf  
echo "net.ipv6.conf.default.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf  
echo "net.ipv6.conf.lo.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf

И установить пакеты linux-firmware и linux-firmware-nonfree.
