mine has now begun to crash while searching for networks..

can someone send me a link to the latest firmware upgrade?

Hi,

I want to give this matter one last try.

I contacted the nokia support twice and got the following answer.
The Europeans don´t feel responsible, since I bought a US-device.
The US-support doesn´t care since it does connect to the wifi channels valid in the states.

Applying different country or language settings does not change anything in terms of wifi channel bandwidth.

The only thing I could imagine to be responsible for the channel limitation is the MAC-address of the device. Lets say the address pools are different for us and european device. By typing in your MAC address prior to downloading the firmware nokia could be able to provide different "localized" versions.

My question now is:
Could anybody of you provide me with a "european" MAC-address so that I can check if the two resulting firmware images differ?

That would be a great help.

Thanks,
Kalle

00:19:4F:9E:9C:4D is the WLAN MAC of my N800 purchased via the UK Nokia store (manufactured in Finland). There's another number below the BT MAC titled Code/Codigo which is 0631673 - I've no idea what it represents but thought I'd mention it.

I am just curious as to what answer [if any] ever came out of this - whether the mac address change worked, or if it was actually possible.

I have a US n800 that I use in the UK and I recently ran in to an issue with a network running wifi channel 13 while visiting Spain. We ended up changing the router to channel 10.

FYI, my language and locale are and always have been set as UK.

Cheers.

You can change the regulatory domain (which channels) via:

/sys/devices/platform/wlan-omap/default_country.

The default it 0x10 and it is FCC but I don't think it says "FCC" (unsigned char [1], char [3]).

Setting the first byte to 0x01 appears to enable through at least channel 13 (2472)

I don't think the driver implements region 0x41 (MTK? japan) to allow 14/2482, but it might be something which can be edited in the source.

These won't show up on the settings dialog (there is a OSSO_PRODUCT_WLAN_CHANNEL variable that says FCC/US), but iwconfig and iwlist should be able to use the extra channels, and you might be able to edit something in /var/lib/gconf/system/osso/connectivity

The setting on my N800 (OS2007) is 0x30. I have 13 channels.

tz1 / TA-t3,

Thanks for the info. I was a bit surprised that no one had replied (and/or tackled this issue) before.

I will try what you have noted and see how quickly I can brick my n800!

Thx.

Since I got some N800s I ordered from the USA, I tried that today. It does not work, for the following reason:

All what you see under /sys/... are not real files. They are only an image of the kernel configuration. It works like the /proc directory.

So to change this variable, one must change kernel option, presumably boot options. Does anyone have an idea how to do that?

The files are virtual, but you can still change the values. That's how you change dynamic, internal kernel values. On desktop systems there's a script run at boot time which reads values from /etc/sysctl.conf and writes the values to the matching files in /sys/. No such file on the N800, so there's probably some other place in the system where values are set at boot time. That doesn't stop you from changing them later.

However, in this particular case you're right - it doesn't seem possible to modify /sys/devices/platform/wlan-omap/default_country. So we haven't yet found where to change / set the wi-fi channel range, only where to see some of the current settings.

EDIT: Correction: The variables controlled by sysctl are in /proc/sys/, not /sys/ as I wrote above. /sys is for exporting kernel data structures to userspace, so in the context we're talking about it's a reference section.

So, probably, what we need to do is to find out where sysctl.conf (or the local equivalent) is hidden, right?
