Wifi перестал подключаться к некоторым сетям после обновления до 20.04
Я обновился с Ubuntu 18.04 до 20.04, и мой ноутбук перестал подключаться к некоторым Wi-Fi-сетям, к которым он подключался раньше, но продолжает нормально подключаться к другим.
Не подключающаяся сеть (HH40V_2014 далее в информации): начинает подключаться, через некоторое время спрашивает пароль, я ввожу правильный пароль, продолжает подключаться, в итоге снова спрашивает.
Сеть подключения (CheckVienna free WiFi далее в информации): подключается нормально, как и раньше на 18.04.

Проверьте ваш WiFi MTU, используя
ip link
также обратите внимание на имя вашего WiFi интерфейса.
MTU MTU (Maximum Transmission Unit) - это размер самого большого пакета, который может быть отправлен за одну передачу по сети. Если пакет превышает MTU канала, данные должны быть разбиты на несколько пакетов (фрагментированы). Эти несколько пакетов должны быть отправлены по каналу, получены, подтверждены и снова собраны на дальнем конце. Если ваш канал неправильно настроен, и вам приходится фрагментировать каждый отправляемый пакет, фактическая скорость передачи данных падает.
В сетях Ethernet (проводных) используется MTU в 1500 байт.
Из-за дополнительных накладных расходов на пакет для WiFi (8 байт PPPoE заголовка), WiFi использует MTU 1492.
Ваш MTU должен быть установлен вашим DHCP-сервером, проверьте конфигурацию вашего маршрутизатора.
Вы можете установить свой собственный MTU (настройка не сохраняется при перезагрузках) с помощью
sudo ip link set dev name mtu 1492
где "name" - имя интерфейса, указанное выше.
Вот пример:
walt@squid:~(0)$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp63s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether 00:24:21:7f:e5:1c brd ff:ff:ff:ff:ff:ff
3: wlxf46d04b1790f: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DORMANT group default qlen 1000
link/ether f4:6d:04:b1:79:0f brd ff:ff:ff:ff:ff:ff
walt@squid:~(0)$ sudo ip link set dev wlxf46d04b1790f mtu 1492
[sudo] password for walt:
walt@squid:~(0)$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp63s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether 00:24:21:7f:e5:1c brd ff:ff:ff:ff:ff:ff
3: wlxf46d04b1790f: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1492 qdisc mq state UP mode DORMANT group default qlen 1000
link/ether f4:6d:04:b1:79:0f brd ff:ff:ff:ff:ff:ff
Имя моего интерфейса WiFi "wlxf46d04b1790f".
Я заметил, что ваши MTU все 1500.
