Yeah, I'll bet this is the kernel issue that Bjorn fixed to work around various quirks that QMI has. The patches are in the 3.9 kernel, and have been backported to the stable 3.4.46 kernel as well. I'm not sure about the status for other "stable" kernel versions. The patches are: net: qmi_wwan: prevent duplicate mac address on link (firmware bug workaround) net: qmi_wwan: fixup destination address (firmware bug workaround) net: qmi_wwan: fixup missing ethernet header (firmware bug workaround) Dan > > > > > > On Wed, May 22, 2013 at 3:39 PM, Aleksander Morgado > > <[email protected] <mailto:[email protected]>> wrote: > > > > On 05/22/2013 06:26 AM, Heiher wrote: > > > Currently, I can connect to network and got the IPv4 address (from > > ISP) > > > of the network interface 'wwan0' by Networkmanager + ModemManager in > > > lastest Arch Linux, but ping any IP addresses (e.g. 8.8.8.8) always > > > reply 'timeout'. > > > > > > > Is it connected to LTE this time? > > > > -- > > Aleksander > > > > > > > > > > -- > > Best regards! > > Heiher > > https://heiher.info > > _______________________________________________ networkmanager-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/networkmanager-list
