A few days ago, I managed to get my wireless network working on ArchLinux.

My network card is:

~/ lspci | grep Network
03:00.0 Network controller: Broadcom Corporation BCM4321 802.11a/b/g/n (rev 03)

systemd-analyze show me that some service takes about 30 seconds:

~/ systemd-analyze blame
         31.543s NetworkManager-wait-online.service
           850ms NetworkManager.service
           166ms systemd-udev-trigger.service
           153ms alsa-restore.service
           151ms systemd-logind.service
           147ms systemd-fsck@dev-sdb1.service
           147ms var.mount
           113ms systemd-tmpfiles-setup.service
           113ms systemd-sysctl.service
           102ms home.mount
           100ms systemd-fsck@dev-sdb3.service
           100ms dev-hugepages.mount
            99ms systemd-random-seed-load.service
            98ms systemd-vconsole-setup.service
            96ms systemd-modules-load.service
            92ms dev-mqueue.mount
            90ms sys-kernel-debug.mount
            67ms tmp.mount
            65ms systemd-remount-fs.service
            65ms polkit.service
            50ms systemd-udevd.service
            50ms udisks2.service
            43ms sys-kernel-config.mount
            25ms rtkit-daemon.service
            24ms wpa_supplicant.service
            16ms systemd-journal-flush.service
            13ms systemd-user-sessions.service
            12ms upower.service
            11ms dev-sdb2.swap

If I disable the 30-seconds service, I still have the same problem. And lshw -C network shows:

The only difference in the latest command before I get connected is that the last *-network got the configuration


instead of:


Do you know how I can get my wireless network to start instantly instead of waiting 30 seconds?

I have the same Network controller. I used this netcfg guide to automatically connecting to my wireless network. Look under 'Automatic Operation'. –  Rany Albeg Wein Apr 26 '13 at 3:09
