wireless dies on batery power?

[vinnywright]

as the title suggests my wireless works just fine wile the laptop is plugged in ......BUT as soon (within 5 minutes) as I unplug it it will start a reconnect sequence and never reconnect?

this is a HP-G62

all this (ifconfig,iwconfig,lsmod,)was wile it was pluged in and working.


when I unplugged it it was working, after a few minutes it started the reconnect sequence and never reconnected, after I plug it back in the network manager (stock one in the system tray) would show NO access points and

sudo iwlist scan

would give NO results..........a reboot (wile plugged in)fixes all...........until unplugging it again of course.

iwlist scan not giving any results makes me think some kind of power management setting is affecting the wireless card ..........but what and ware?

any and all help is appreciated

humm .......will try it later.......last post#4

in 11.04 I did half to compile the driver but from 11.10 on it had support (I thought)........I never noted the dropping on battery before as it is usually plugged in .....

well strangely enough I just updated my 12.10 partition (which WAS doing the same thing) and after the update the wireless is staying on on battery power .... and after a sleep .

lsmod shows the same modules as 12.04 ........ (rt2800pci) strange .

on a 3.4.0-3-generic kernel with the 12.10 partition.

still thinking some kind of power management setting somewhere in the 12.04 partition is the culpret ................................................

Power saving is achieved by the pm-utils package, which is installed by default. When changing modes the scripts in /etc/pm/power.d and /usr/lib/pm-utils/power.d are run (The scripts in /etc take precedence).

There is a script in there for wifi powersaving, so it might be worthwhile disabling that script. Logs are in /var/log/powersave.log.

the wireless script in /usr/lib/pm-utils/power.d is identical in both systems as shown by kdiff3 !!

the /etc/pm/power.d is empty in both systems !!

any more ideas as to ware to look ??

Well this seems to have sorted it's self out.
as of the dist-upgrade on the 12.04 partition today which included these packages

The following packages will be upgraded:
ia32-libs ia32-libs-multiarch:i386 libsnmp-base libsnmp15 libxml2 libxml2:i386 libxml2-utils linux-headers-3.2.0-24 linux-headers-3.2.0-24-generic
linux-image-3.2.0-24-generic linux-libc-dev python-libxml2 resolvconf

the wireless has been on on battery power for 45 minutes without issue............Hummm?
