Всем, привет.
Столкнулся с проблемой на прошитом LEDE (форк OpenWRT) роутере - через какое-то время после подключения пропадает Wifi. Промежутки работы/не работы произвольные. Связь по Wifi пропадает полностью - даже до шлюза с телефона пинга нет. Однако, на LEDE я вижу в листинге tcpdump, что пакеты на него приходят, но обратно ничего не уходит.
Проблема проявляется на всех беспроводных устройствах без исключения, независимо от ОС.
Вот пример tcpdump во время проблемы:
root@LEDE:~# tcpdump -e -i any host 192.168.1.246 [4/1926]
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on any, link-type LINUX_SLL (Linux cooked), capture size 262144 bytes
