Виталий Гладкий Posted March 7, 2018 Posted March 7, 2018 Hi everybody! Need some help with understanding of some stuff in my Orange Pi zero. I have next issue: I have Orange pi Zero and Huawei4510 3g usb modem. Orange pi do some measurement and send them on server. All this stuff works great.But: my provider have session limitation(3 hours). After 3 hour i lost my orange pi from netework, but i see that 3g modem lighthing as he have connection.When i turn-off modem from usb and plug it again, he lighthing that he catch network, but services doesnt sent data. i'm using wvdial for managing network connection over 3g modem. I have script whitch reload wvdial connection. I tried : - reset wvdial every 1 or 3 hour - reset my services - service network restart every 1 hour - kill ppp0 interface Made experiment: - i wrote script which writes ping result in file by crone every 10 minutes. after 3 hours he lost network The only thing that help to reconect devices is reboot. Is it something wrong with network interfaces or wvdial? Maybe someone can help. I will be glad to all the answers.
