а не пробовал? ifconfig wlan0 down && ifconfig wlan0 up

Я перед wpa_supplicant пробовал Service netif restart. Оно же и так перезапускает wlan0?

netstat -m ?

Очень странно но в логах появилась запись о выдачи ip адреса от прошлого подключения!

Как такое может быть?

dhclient: New IP Address (wlan0) :172.20.10.1
Но это адреса другого подключения

Убей от рута dhclient и вручную запусти dhclient wlan0

Интересно отработает ли

Попробую!

Ну хоть не гомониграми

сначала пытался понять, что за гомология и энграммы

гомология с энграммами вон выше

Не помогло!
