UMTS modem stopped working

Post by expatMT »

I have a Qualcomm modem installed in a HP ProBook 5320m laptop. NetworkManager picks up the device and I can use the wizard to create a connection to my service provider (Vodafone Malta). Re-loading the qcserial module shows the following log entries:

However, when attempting to activate the connection, I see the following in syslog:

Is there any way I can get more detailed information from the process to identify where this is failing?

We could look at the output of:

Code: Select all

uname -a
inxi -Nxc 0
lsusb
dmesg | grep -Ei 'firm|gobi|error|fail'

lsmod

Compared with your previous output from syslog:

You might need to update the module. This could mean that you have to compile the drivers.

Code: Select all

[63345.909177] ICMPv6 checksum failed [2XXX:XXX:0000:0021:0000:0000:0200:0001 > 2XXX:XXX:ffff:0081:6ab5:99ff:fee7:0721]
I've read this only happened in old kernels. But the amount of these messages tells me that you maybe should deactive IPv6.
