been using usb multi tech modem verizon through pi given test. got through issues have connecting now, whats odd went through updates pi , not. if use year old image @ shutdown command modem works great , merely resets modem no pi change. since updating current whenever send @ command shutdown modem (i have small script watch teh ppp connection auto reconnect. if sees no ppp connection resets modem having issues busy line, trys redial.) at#shdn @ command, since have updated when run script or command minicom resets entire device. thinking maybe hotplug issues have tried upgraded cap , still remains same. modem pulls power seperatly have 5v 4amp psu splits power pi , modem on shared line. curious if has thought why entire system restarts when before updating works day long. edit: measured boards current while running command , voltage stays around 5 seems not current drop. created sd , updated left out firmware update , seems normal. maybe update fluke. raspberrypi
