Is it possible that after the new update all I can do with QCPUFreq is maximum 750MHz and onlu with SmartReflex? I tried to turn it off and change to 950MHz, then save as preset but after reboot it is still max 750 and Smart

When I am on my home wifi, I am always near the access point. Thus I do not need the full 100mW of wifi power. I can use just 10mW and still have perfect connection. Similarly, at work I am in the middle of 3 dd-wrt routers all cranking out 250mW of power, I can get away with just 2mW of wifi power there. Adjusting wifi power by the 'connections' settings is a pain in the testicles and cannot be done for each network separately...

In maemo (an most linux's) there is is a directory called /etc/network/if-up.d. Any scripts in this folder will be run as root whenever I 'connect'...

So, you create a file called:

Code:

/etc/network/if-up.d/50_wifiscripts

Containing:

Code:

#!/bin/sh
essid=$(iwgetid -s)

if [ "$essid" == "qwerty12" ]; then
	iwconfig wlan0 txpower 7
	echo $essid
elif [ "$essid" == "work" ]; then
	iwconfig wlan0 txpower 3
fi

This means when I connect to qwerty12 (home) or work the power is reduced appropriatley.

Similarly, at the other end:

Code:

/etc/network/if-down.d/50_wifiscripts

Containing:

Code:

#!/bin/sh
iwconfig wlan0 txpower 20

To put power back to max when I disconnect (so you can still connect to other networks).

You can stick other stuff in these directories too. For example, switch to work profile when I connect to work wifi.

This lets me stay connected to wifi all day without even batting an eyelid!

yep yep yep
vi_'s trick

Amazing karam. Currently testing. But with the whole CSSU update my battery performance cannot be tested as it should.

I didn't get that one, man. What do you say that can be checked in conky? You mean CPU clock, any process, or what?

Thanks in advance.

CSSU new update + batterypatch = reboot during calls

In my case.

Try to see the cause.

karam | # 2117 | 2011-09-07, 14:46 | Report

@jpala16
you can check the percents left in conky
time for about 10 minutes and check the conky before
and after
you will notice without batterypatch each 10 minutes 4% are gone
now each 10 minutes 1or2 % are gone (this is in my case you might have different results)

@WhiteWolf
i haven't tried the new CSSU update
but the problem is probably with the voltages
edit the file /opt/dbus-scripts/cpu_normal
and change kernel-config load overclock
to
kernel-config load $the profile which is stable with u

but the default custom profile with batterypatch are the best for battery saving

Karam said that the patch might not be stable with all N900's.. try out different profiles by Karam or else wait.. he will be uploading the old battery patch soon(c some posts back)
