UMTS 连接失败,并显示“LCP 由对等方终止”

UMTS 连接失败,并显示“LCP 由对等方终止”

我使用联想 Thinkpad T440s 中的 Ericsson N5321 gw 卡连接到 T-Mobile(由 debitel 转售),操作如下/etc/wvdial.conf(在 debian sid x64 上):

[Dialer Defaults]
Modem = /dev/ttyACM2
Baud = 460800

Phone = *99#
Username = t-mobile
Password = tm
Stupid Mode = 1

Modem Type = USB Modem
New PPD = yes

Dial Command = ATDT
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","internet.t-mobile"

但是,当我尝试连接时,ppd 失败并显示代码 16 和日志:

Aug  3 09:47:01 t4 pppd[3592]: CHAP authentication succeeded:
Congratulations!
Aug  3 09:47:01 t4 pppd[3592]: CHAP authentication succeeded
Aug  3 09:47:01 t4 pppd[3592]: LCP terminated by peer
Aug  3 09:47:01 t4 pppd[3592]: Modem hangup

我怎样才能使连接正常工作?

答案1

要实际使用调制解调器进行互联网连接,您需要使用命令激活它AT+CFUN。修改wvdial.conf以发送AT+CFUN=1

[Dialer Defaults]
Modem = /dev/ttyACM2
Baud = 460800
ISDN = 0

Phone = *99#
Username = t-mobile
Password = tm
Stupid Mode = 1

Modem Type = USB Modem
New PPD = yes

Dial Command = ATDT
Init1 = ATZ
Init2 = AT+CFUN=1
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init4 = AT+CGDCONT=1,"IP","internet.t-mobile"
