I dont use mpd, only the built in ppp. Can you try it with the built in ppp ? Looking at your log snippets LCP: no reply to 1 echo request Does it ever respond to LCP Echo or LQR ? If not, try disabling that. You wont have link detection, but it might be some incompatibility with mpd. I use an older Sierra Wireless LTE modem on an APU and it works great with the built in tun/ppp combo. *pppgprs: set device /dev/cuaU0.3 set server /var/run/gprs-internet "" 0177 set speed 921600 set timeout 0 set authname wapuser1 set authkey wap set dial "ABORT BUSY TIMEOUT 2 \ \"\" \ AT OK-AT-OK \ AT+CFUN=1 OK-AT-OK \ AT+CMEE=2 OK-AT-OK \ AT+CSQ OK \ AT+CGDCONT=2,\\\"IP\\\",\\\"ltemobile.apn\\\" OK \ AT+CGACT?
