net-auto-wireless roaming with suspend

grine · 2012-03-12 13:23:49

I didn't really know how to name this thread, but I think the gist of it is up there.

I bring my laptop to school and back every day, and use different wireless networks in each place.

I use net-auto-wireless (n-a-w) to connect on boot, but after suspending, and resuming in the new location I have to manually restart the daemon to get a connection back. I'm not sure if n-a-w is supposed to handle this use case, or if there is a better way to handle it.

Any tips?

I was about to start a thread for this myself, placing a comment to track it back.

You don't say how your suspend is configured, but a work-around may be to use a hook on suspend to bring down the wifi-link before suspend (suspend log should show what is happening currently). A bit harsher work-around may be to just suspend the wifi-module.
As for your question, if net-auto-wireless can do it itself (like one would expect), I don't know.
Does it resume properly, if you are still in the same location?

Yes, for me it does.

I was also in the midst of researching this very same problem! Anytime I suspend or sleep my computer from KDE (the only desktop I've tried to do so from thus far), when I bring it back online the auto-net-wireless daemon resumes (or rather, the script is reported as running in the return from "rc.d list"), but the net-cfg_wpa_actiond is not running, and needs to be manually resumed. In my case, whether I'm on the same network or have moved locations, the network does not restart itself automatically.

I use net-profiles, not net-auto-wireless, so take whatever you want from this, but I stop it on suspend and restart it on resume - works fine that way. In my case, I use the default pm-utils script for netcfg, but that won't work if you're changing network, so someone should create an alternative that stops and then restarts net-auto-wireless.

Those of you have net-auto-wireless, please stop saying "me too" and provide relevant logs from wpa_* stuff. When you suspend, wpa_supplicant deauthenticates -- what is the reaction of wpa_actiond? For example:
dhcpcd[852]: wlan0: removing interface
wpa_actiond[674]: Interface 'wlan0' disconnected from network 'lsusecure'

After you wakeup the machine in a different location, is there a profile corresponding to your previous network in /run/network/profiles/?

@tomk:
I used net-profiles until very recently (when switched to net-auto-wireless) and suspend worked out of the box... you should probably investigate your problem further.

Also, putting a script into /etc/pm/sleep.d which stops net-auto-wireless will cure the suspend problem...

I would - if I had a problem.

Now tomk, admitting you have a problem is the first step to recovery. Just provide those logs please, we're here to help you.

@Leonid.l:
You'll have to forgive me for being a little slow, but I'm on the newer side to Arch. Can you direct me to where I might find some of those logs? Specifically logs for the wpa_actiond since that seems to be what gets killed without restarting when I sleep my machine?

bump... I'm still experiencing this issue... any help would be greatly appreciated

I switched to wicd, problem solved.

(sorry..)

Not ideal, but it does work. Guess I'll have to wait for a later version of netcfg to see if the problem ends up fixed.
