Angstrom & OpenZaurus / Wifi And Suspend

« on: April 23, 2005, 11:57:26 am »

A couple of us on #openzaurus put together a quick-hack package to make the 6000L internal wireless survive a suspend.  Be aware that there seems to be something preventing the Power button from triggering "apm -s", so use the menu in Opie or the command line for now.

This is for OZ 3.5.3, btw.

Sure enough, both "ifconfig -a" and "iwconfig" show no wlan0 device.  But lsmod shows the p80211 and prism2_usb modules loaded.  And dmesg seems to indicate that prism2_usb is registered with usb.c.  So what's the deal?

To calrify, after a reboot and a successful "ifup wlan0", "dmesg" looks like this:

Code: [Select]

When it resumes from suspend, I can get the first line by modprobe-ing, but nothing else happens.

I have Opie 1.1.7 on OZ 3.5.2 on an SL-6000L.
When I suspend (or when it suspends on its own), the wifi connection becomes hosed.
I want to modify the script, or put an intermediate step in that calls "ifdown wlan0" in the suspend sequence. What script (or binary) does the suspend call?

I have the same problem with OZ 3.5.3 (using OPIE) and a 6000L.  Despite being an experienced Linux user, I can't for the life of me find out why the wlan0 device won't "come back" after a suspend.  Your idea of manually shutting it off might be a suitable workaround.

I'm not familiar with hotplug (no USB devices on my usual Linux boxes), but everything _looks_ okay from what I can tell.  When I resume from any kind of suspend, I get the following whenever I run "ifup wlan0":

wlanctl-ng: No such device

Sure enough, both "ifconfig -a" and "iwconfig" show no wlan0 device.  But lsmod shows the p80211 and prism2_usb modules loaded.  And dmesg seems to indicate that prism2_usb is registered with usb.c.  So what's the deal?
