It isn't going to work any other way. -- Willie Matthews matthews.willi...@gmail.com 702.659.9966 Just a old computer geek! signature.asc Description: OpenPGP digital signature

Have you tried iwconfig? Il 18/07/2014 18:28, Jarry ha scritto: Hi Gentoo-users, I added the 2nd network adapteer to my gentoo-box and I want to use it. But...

So how can I find name of the new network adapter? Jarry Here's the QA message for sys-fs-udev-215 that might be helpful: Messages for package sys-fs/udev-215: Starting from version = 197 the new predictable network interface names are used by default, see: http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames http://cgit.freedesktop.org/systemd/systemd/tree/src/udev/udev-builtin-net_id.c Example command to get the information for the new interface name before booting (replace ifname with, for example, eth0): # udevadm test-builtin net_id /sys/class/net/ifname 2 /dev/null You can use either kernel parameter net.ifnames=0, create empty file /etc/systemd/network/99-default.link, or symlink it to /dev/null to disable the feature. You need to restart udev as soon as possible to make the upgrade go into effect. The method you use to do this depends on your init system. For sys-apps/openrc users it is: # /etc/init.d/udev --nodeps restart For more information on udev on Gentoo, upgrading, writing udev rules, and fixing known issues visit: http://wiki.gentoo.org/wiki/Udev http://wiki.gentoo.org/wiki/Udev/upgrade

I just checked /sys/class/net/ and found new adapter called enp11s0 there. With ifconfig I can bring it now up and cofigure. Thanks!
