Whoa, that would be great! If ad-hoc is working fine, then, AFAIK, we can consider packet injection modules as fully working replacement for vanilla wifi drivers, and stop that mumbo-jumbo with loading and unloading in all aircrack-ng frontends/implementations. Not to mention another thing crossed from list of closed bits.

whilst tesing for pali then it may be worth checking power consumption between stock and packet injection modules for everyday us.

Re: [Announce] kernel-power stable v52 in Extras

I actually started testing this while on train and hoped to report ASAP, but somehow, I managed to screw installation and I'm stuck on u-boot console with:

Code:

Booting attached kernel image...

Wrong Image Format, for bootm command

ERROR: can't get kernel image!

... for now. Which is quite strange, as I've installed all packages from Pali's link:

Code:

kernel-power-bootimg_2.6.28-10power53_armel.deb

kernel-power-flasher_2.6.28-10power53_armel.deb

kernel-power-modules_2.6.28-10power53_armel.deb

kernel-power-settings_0.18_armel.deb

kernel-power_2.6.28-10power53_armel.deb

...and run u-boot-update-bootmenu, which seemed to create bootmenu.scr without any errors. Probably just "clumsy me" and off-topic here *shrugs*, but I must postpone testing until i dig out (long forgotten, never managed to screw u-boot powered kernel installation before, eh) info on how to recover from that situation.

Re: [Announce] kernel-power stable v52 in Extras

This looks like damaged uboot mtd as uboot is not able to boot attached kernel. BTW, if you did not create custom combined uboot image, than attached image is not kp53...

Re: [Announce] kernel-power stable v52 in Extras

For the record - I've answered in u-boot thread:
http://talk.maemo.org/showpost.php?p...&postcount=756
...as it's OT here and I don't want to clutter kernel-power thread.

As for new wifi modules - I can (happily) report that ad-hoc wifi seems to be working perfectly fine now :) Apart from obvious lack of device reboot on trying to establish ad-hoc network, I was able to set-up one, connect to it from laptop, and share N900's cellular internet access through it. Same thing worked in reverse.

Here good news end, though. As for power consumption, I did some tests - with everything disabled, screen locked and wifi ON but *not* connected to anything, power draw is the same for vanilla and injection modules. But, with device connected to managed network (access point) but idle (no VoIP accounts, no ssh, no anything) with vanilla drivers, device use ~15-20 mA. The same situation for injection modules results in ~200 mA current draw :(

During heavy network usage and/or ad-hoc, vanilla and injection modules result in roughly the same power draw, so I suppose that some powersaving during idle is still lacking in replacement modules. This gives biiig regression re standby time, so using them instead of vanilla ones all the time doesn't seem to be such a good idea YET, after all :(

Re: [Announce] kernel-power stable v52 in Extras

Ok, thank you for testing ad-hoc networks, its good to know that ad-hoc mode is working now.

When I'm using packet injection modules I see error messages about power save mode in dmesg. So this looks like problem...

You can try to enable/disable power save mode via:
$ sudo iwconfig wlan0 power on
(or off)

Anyway we still need to test if packet injection function still working. Patches which fixing ad-hoc mode probably disabling packet injection support when adapter is in ad-hoc mode. But this needs to be confirmed first...

Re: [Announce] kernel-power stable v52 in Extras

Just a reminder to anyone volounteering to test it - don't trust aircrack-ng's injection test, I vaguely remember it lying that injection is working even, when it wasn't. Test it on actual (your own) WEP access point.

I would do the test myself, but I've, actually, purged everything WEP-related from my open-wrt powered router, and no WEP network in scanning range anymore, here (not that I would test it on someone's other network without their permission, of course ;) ). So, i must skip this test in someone's else favor.

// Edit

BTW, any changelog for kernel-power-settings18?

It is in DEB package :-) But if you cannot unpack AR & TAR.GZ archive here it is. Just small changes:

Code:

  * start upstart script after mounting /home and /opt

  * upstart kernel-modules file is service

Re: [Announce] kernel-power stable v52 in Extras

where I can find the changelog for kp53?

by scrolling up all the way to #219.

Or just like that:

Keep trying ... :cool:
