[Bug 1969241] Re: Network issue no IPv6 using Sierra Wireless EM7421 and mbim
apport information ** Tags added: apport-collected jammy third-party-packages ** Description changed: Network issue no IPv6 using Sierra Wireless EM7421 and mbim Description:Ubuntu Jammy Jellyfish Release:22.04 Linux 5.15.0-25-generic I need to connect via GSM to Internet using IPv6. IPv6 not present in config. Internet connect works with IPv4 although issues seem to exist. EXPECTATION: IPv6 shall work properly like the EM7455 with same card in very similar machine, Ubuntu. IPv6 shall work properly like in Linux-Mint 20.3 on this machine, this setup. All using the same driver=cdc_mbim ENVIRONMENT: - SIM is working properly, - EM7421 latest firmware applied, - EM7421 capable doing IPv6 with this setup (according to spec + test with Win10 + works with Linux Mint); "package" not understood, sorry. ModemManager probably? ASSUMPTIONs: - Missing IPv6 is a wrong config / bug in software / communication issue. - IPv6 communication can be enabled by adjustment rather than by code changes in cdc_mbim or redesign of SierraW. EM7421 device. - Some enhancement / fix can enable IPv6 communication. REMARK: Linux-Mint 20.3 una is capable of running the 'EM7421' in proper IPv6 "mode" (kernel 5.4.0-107-generic). It uses driver=cdc_mbim as well. It shows other issues like missing provision of additional DNS server data, EUI64 state and the like.
