SIM card is detected
(1) no connection
(2) 30s reaction time to any single user click
lenovo X200 with build-in WAN (Ericsson F3507g, currently not supported afaik), no SIM card inserted
USB stick with HUAWEI Mobile
linux kernel 28.6.28
What I did:
looked up the ttys associated to the same USB device as the HUAWEI controller: "dmesg | grep HUA" -> USB 4-1, "dmesg | grep 4-1" -> ttyUSB5,ttyUSB6.
started umtsmon with "sudo umtsmon -s ttyUSB5,ttyUSB6", entered the PIN, a network is found, however, connetion timed out.
Now, umtsmon is left nearly unusable. Any state change in the user interface takes 30s. Programming error in error processing?
Fortunately the x200 comes with a switch to disable Bluetooth, WLAN and WWAN. I got to re-boot with the disable switch activated. HUAWEI is found on ttyUSB0 and 1., network is found and I'm able to connect to it - the system is working.
As I do have a workaround, this issue is meant to improve error handling of umtsmon.
