(from memory)
Settings->Connections
Edit your connection.. next, next, next, advanced
Flip over to the last tab, and there should be a powersaving dropdown box; select Off
If it fixes it, this may be a new bug.
from canada i have nokia n900 version :3.2010.02-8.002
everything works fine... but the wifi and the bluetooth is not working when i search for my router my n900 says "no connection available... even the bluetooth

did this problem only occur after installing the kernel-power-flasher?
If not, then this is not the appropriate thread for such questions.
This thread is only about the "community" kernel.

but it increases the battery drain drastically.
There are several WLAN bugfixes in the PR1.2 patches which might have caused
the higher latency. the IPv6 support and the 2.6.28.10 patches could be alternative causes but I suspect its the PR1.2 fixes.
I'll do a test with a kernel w/o the those fixes.

On another note, everyone check out these voltages I'm running now!
I sat and tweaked each individual voltage whatever the device was stable at, plus 2. Can't wait to see what my battery life is like now.Code:VDD1_OPPS_VSEL="17 17 20 30 33 35 40 43 45 47 50 53 58 64 70"
I'm currently using 250 / 500 / 750 / 1ghz.
@titan
@nightfire
Can you provide the WHOLE table of voltages with kernel values and corresponding voltages. Which is the lowest possible, the highest possible and the formula and/or table for all possible voltages?

check the wiki and this table
17 = 0x11 = 0.812V x 0 MHz = 0
17 = 0x11 = 0.812V x 125 MHz = 83
20 = 0x14 = 0.850V x 250 MHz = 181
30 = 0x1e = 0.975V x 500 MHz = 475
33 = 0x21 = 1.012V x 550 MHz = 564
35 = 0x23 = 1.038V x 600 MHz = 646
40 = 0x28 = 1.100V x 700 MHz = 847
43 = 0x2b = 1.137V x 750 MHz = 970
45 = 0x2d = 1.163V x 810 MHz = 1095
47 = 0x2f = 1.188V x 850 MHz = 1199
50 = 0x32 = 1.225V x 900 MHz = 1351
53 = 0x35 = 1.263V x 950 MHz = 1514
58 = 0x3a = 1.325V x 1000 MHz = 1756
64 = 0x40 = 1.400V x 1100 MHz = 2156
70 = 0x46 = 1.475V x 1150 MHz = 2502
17 = 0x11 = 0.812V x 0 MHz = 0

I'm curious if this voltage map is stable for anyone else. Been 24 hours and no lockups, oopses, segv's, or anything.

No problems whatsoever.
