I just experienced issues with a C881G-4G-GA-K9 (no IP-Address on the interface, no service...).
In the output of show cellular 0 all, in the Data Connection Information I got following:
Data Connection Information
Profile 1, Packet Session Status = INACTIVE
Call end mode = 3GPP
Session disconnect reason type = 3GPP specification defined(6)
Session disconnect reason = Authentication failed(29)
Tried to find out what is the meaning of codes (6 and 29) but without success.
Can anyone help me out?
Thank you in advance!
all I could find were some generic 3GPP reason codes that don't help a lot.
Can you post the output of:
sh cellular 0 radio
of course, there you are:
Radio power mode = online
LTE Rx Channel Number = 1300
LTE Tx Channel Number = 19300
LTE Band = 3
LTE Bandwidth = 20 MHz
Current RSSI = -68 dBm
Current RSRP = -0 dBm
Current RSRQ = -0 dB
Current SNR = -18.3 dB
Physical Cell Id = 217
Number of nearby cells = 6
Idx PCI (Physical Cell Id)
Radio Access Technology(RAT) Preference = AUTO
Radio Access Technology(RAT) Selected = LTE
sorry for my late response. I was checking the RSSI/RSRP/RSRQ/SNR levels, but they all look very good...
As said, the 3GPP disconnect reason is just a generic one. Does this occur often ? If so, turn on debugging (debug cellular 0), also, can you post the output of:
show cellular 0 profile
