Hi Jaejeon, The error you have reported seems to be similar to #20.
As provided in comment #23, We had manually downloaded the 5.17 specific kernel deb packages from https://launchpad.net/~canonical-hwe-team/+archive/ubuntu/intermediate-kernel/+packages and we were able to successfully connect to the modem. We did no see the issue that you are mentioning. We could use the mmcli -m 0 to get the modem firmware version Please share the logs for your reference. Any idea which modem firmware you are using ? As indicated by Stephane in #30, you would need to get the latest modem firmware from Fibocom colleauges and update the firmware using Telephony tool provided by us in #27, if you have access to windows setup Thanks and Best Regards, Murali -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1950282 Title: Fibocom WWAN FM350-GL-00 (Mediatek M80 5G) support To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1950282/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
