Laptop WAN issue with dhcpcd and NetworkManager

Postby amrs » Wed Jul 30, 2014 17:39

I have a Thinkpad X201 laptop with builtin WAN card from Qualcomm. It doesn't work in Sabayon via NetworkManager, apparently the problem is that dhcpcd crashes when run against wwan0 interface. And of course, Sabayon's NetworkManager ignores the config directive to use dhclient instead of dhcpcd.

I can use the modem from command line, calling mmcli and dhclient manually and it works fine. However, NetworkManager still thinks I'm offline and kmail thinks that too. So no emails.

I guess I'm asking what can I do that actually leads to a resolution? Would a bug report against dhcpcd get fixed in reasonable time? What about a feature request for NetworkManager? Or should I just emerge NetworkManager myself and enjoy?

according with Gentoo Wiki :

Note that NetworkManager will not connect if other services are also managing connections. So you need to remove them, if you have them installed.

Remove dhcpcd service and keep on NetworkManager only.

Thanks for the response but you're way off. dhcpcd not a service, it's a dhcp client that NetworkManager runs.

In case it wasn't clear, here's a recap. I can solve my issue by

  1. Fixing NetworkManager so that it runs dhclient instead of dhcpcd.
  2. Fixing dhcpcd so that it configures the wwan0 interface instead crashing.

in my net, of my house computer,
I have DHCP.

The procedure that worked for me was remove all Networkmanager packages, (and their services in systemd), without removing the dependencies

I installed WICD, run "new Wi-Fi connection" in it

and this works both with dhclient and dhcpcd, Both Works,

in fact, i seted "auto" in WICD, and default running in it is dhcpcd, but i tested with dhclient and it also works.
