At this moment, you have to compile webcam driver yourself.

P.S. If someone help us with this task (tests and maybe additional patches), it will be much faster...

I'm always up for beta testing:)

btw, what drivers would you propose?
still stick to the good old pwc and OV511 drivers?
http://www.saillard.org/linux/pwc/
http://ovcam.org/ov511/

I mean there are some other drivers out that support more and are designed for kernel 2.6

I'm not use usb webcam, so I don't know ;)

Of course, we should use recent drivers for 2.6 & V4L2 (video for linux v2).

V4L2 kernel module is included in the extra modules already (v4l2-common.ko) as far as I can see, so that's the first step:p

Now the webcam drivers are all a bit old, latest updates from 2006 or so...
but our kernel is a bit old as well :p

Modern distro's usually use the UVC driver (http://www.ideasonboard.org/uvc/)
but it seems that it's unusable because it doesn't support still imaging on which the current webcam setup is based if I'm correct:p
yet, it supports an impressive list of devices

so... I'm unsure: change the webcam page with the UVC driver or use the good ol' drivers :p

ov511 drivers need some extra twi/i2c kernel modules for 2.6 apparently

Wireless signal weak

I have noticed a problem with the strength/range of the wireless signal.
As soon as I install Oleg Firmware the wireless range become very limited!!!

With Oleg Firmware (RT-N16-1.9.2.7-rtn-r1639) the wireless signal is only good in the same room - but with Asus Firmware (1.0.1.2) I have strong signal everywhere in my house.
Just to confirm the settings:

This is with Asus firmware 1.0.1.2:
# nvram show | grep power
size: 18028 bytes (14740 left)
wl0_radio_power_x=17
wl_radio_power_x=17

And this Oleg:
nvram show | grep power
size: 14159 bytes (18609 left)
wl0_radio_power_x=19
wl_radio_power_x=19

Everything is default values (factory default after installed).
I have tried other values (30, 50 and even 84) but no big difference!

Is there something wrong with how Oleg handles the three antennas on the N16 - since stock Asus 1.0.1.2 has strong signal and Oleg VERY weak?
I´ve also tried Asus 1.0.1.6 (found on their FTP) and this was ALSO weak signal!
Can somebody check and confirm this?

check signal and other ssids with this

feel free to post screenshoots here then

Below are the screenshots. Notice that Asus signal strength is better (-70dBm). Oleg is almost unusable (-85dBm) - even though "radio power" is 19 in oleg but only 17 in asus! Why:confused:

Here´s asus 1.0.1.2 (I´m "WATERGATE"):
Signal strength ~ -70dBm

And here´s RT-N16-1.9.2.7-rtn-r1867:
Signal strength ~-85dBm!!!:confused:

Also a speed difference

Here come some poor observations and surggestions from a noob. :)

I see that asus 1.0.1.2 has a speed of 65 and the RT-N16-1.9.2.7-rtn-r1867 a speed of 54.

Is this due to the difference in signal strength?

Have you tried to measure the strength with another computer/network card?

1.Is this due to the difference in signal strength?

1. Don´t think so - Oleg was configured G only. Maybe that´s it - cause I tested again with asus 1.0.1.2 also G only and then it measured 54. Still stronger signal though!
2. Yes - tested with another laptop (different brand) AND my PS3. Same result...

Best would be if someone could install 1.0.1.2 and confirm if they also get stronger signal....

speed is the (maximum) basic rate measured if I'm correct...

I'm wondering though... why G only?
if you set wireless mode to auto everything is supported :rolleyes:

Here I can still use internet at 50m distance trough trees and walls.
moreover, turning the wifi power up doesn't necessarily increase the network strength

Well - I just tested all possibilities to see if anything would increase signal - and it didn´t, so I just happened to make the screenshot at the "wrong time":o
Nevertheless - I still have lower signal with Oleg than with Asus firmware. Same settings...

Quoting myself just to show what I´m referring to
I´m a total noob at this - so I do not know how to check - BUT can there be something with MIMO settings for the antenna?

in the nvram you can change:

Quote:

wl_mimo_preamble=mm
wl0_mimo_preamble=mm

(standard)

moreover you can do some advanced settings with the wl command. (see attachment)

I don't know much about this, so you can break it, or you can make it:o

The last command in the "wl help" looks very interesting:

Quote:

mimo_ss_stf
g/set SS STF mode.
Usage: wl mimo_ss_stf <value> <-b a | b>
value: 0 - SISO; 1 - CDD
-b(band): a - 5G; b - 2.4G

If that value is set to 0 (SISO=single input/single output) then RT-n16 would use only one antenna, right?
Am I the only one with weak wireless signal (with Oleg firmware - Asus stock is normal)???

I have this same problem
