Wicd And Netcfg not reconnecting from Sleep\Suspend

Hi, I've installed both of these network managers and neither one, after the laptop going to sleep\suspend\hibernate is able to reconnect to my wifi network.  I'm using simple WEP encryption.  I have to restart the machine in order for them to reconnect again, does anyone have an idea why this is happening?

Thank you

Re: Wicd And Netcfg not reconnecting from Sleep\Suspend

netcfg works with suspend/hibernate for me. Did you make any changes involving /usr/lib/pm-utils/sleep/11netcfg?

No, I didn't make any changes.  I made a basic setup of netcfg and tested the sleep>reconnect and it didn't work so I reinstalled wicd-bzr which I really like the GUI and features of.

Re: Wicd And Netcfg not reconnecting from Sleep\Suspend

Could you post the output of

$ lspci | grep Network
03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

What happens after suspending, does it appear to attempt connection?  In particular, what is the output of:

iwconfig

Does manually brining the connection down / up with netcfg give any interesting errors?

Weird thing is that when I shutdown or restart the system isn't able to stop the daemon and gives a FAILED mark next to it because of python or something, is that normal?

Re: Wicd And Netcfg not reconnecting from Sleep\Suspend

That seems fine.  I have the same wireless device which connects without issue after resuming.

It doesn't sound normal, though I'm afraid I'm not familiar with wicd (I imagine that's the daemon you're referring to).

Could you post the output of:

ip addr show wlan0

does the output appear correct for your network?

Re: Wicd And Netcfg not reconnecting from Sleep\Suspend

I don't seem to have the "ip" command in my system.
Wicd, upon resume, tries to reconnect and then says it wasn't able to receive an ip address.  When it scans for networks, the networks become grayed out.

The 'ip' command is part of 'iproute2'.  An alternative is 'ifconfig wlan0', which should already be available.  (I intentionally avoided this before as it is deprecated, though it still works perfectly well ).

Are you able to establish a connection if you assign a static IP?

Re: Wicd And Netcfg not reconnecting from Sleep\Suspend

I'm able to have wireless working after sleep only after I reload the interface and driver via these commands:
sudo ifconfig wlan0 down
sudo modprobe -r iwl3945
sudo modprobe iwl3945
sudo ifconfig wlan0 up

Isn't there a way to do this without having to run these commands every time?  Why is the system not reconfiguring wireless on wake?

Re: Wicd And Netcfg not reconnecting from Sleep\Suspend

Not sure why the module must be reloaded after suspend.  Is there anything in /var/log/messages?

It shouldn't be too difficult to work around this.  I suggest adding a hook to pm-utils to bring the connection down and remove the module prior to suspend / hibernate, then on resume have it reload the module.  Assuming you're using pm-utils to suspend, the example here should help.

Re: Wicd And Netcfg not reconnecting from Sleep\Suspend

I have the same problem. It was introduced with kernel 2.6.32 and may be related to the b43 driver. Are you using these kernel and driver by any chance?

Re: Wicd And Netcfg not reconnecting from Sleep\Suspend

Mine is the intel iwl3945 driver but the funny thing is that the b43 driver also worked for me in xubuntu.  You just need to modprobe The driver and remove it upon sleep.  So, modprobe iwl3945 -r upon sleep/hibernate and modprobe iwl395 upon wake.  Place the file in /etc/pm/sleep.d/ and sudo chmod +x the file and voilla it works correctly.

Re: Wicd And Netcfg not reconnecting from Sleep\Suspend

I get the same problem on my ath5k card. changing from wicd back to networkmanager makes no difference. This is a weird issue. A better fix than the above should really be found - although I'll do that. I had assumed it was a wicd issue....

Re: Wicd And Netcfg not reconnecting from Sleep\Suspend

I was having a similar problem after the 2.6.32 update.  It may be related to the IPv6 module.  If you don't need that you could just stop it from loading and see if it works.  Check the last couple posts in this thread for more info - http://bbs.archlinux.org/viewtopic.php?id=87802&p=2

Re: Wicd And Netcfg not reconnecting from Sleep\Suspend

I've completely give up on Wicd and have since installed wpa_supplicant.  The software is still too buggy at this point.  Wpa_supplicant with wpa_gui meanwhile works like a charm and does the job quite nicely with a script I've found online for rc.conf.
