intel 4965 wifi

Hello.
The notebook comes vtroennaya wifi card which is defined as the intel 4965.
Using iwn driver in freebsd 8 get txpower = 15, using iwn in freebsd 7 txpower = 50.
But the relationship in both cases is quite stable broken.
How can I correct this situation.
Write PR?
 
I would like to increase the value txpower.
If I fetch the file via wifi then the rate begins to drop and suspended load (1 mb)
If you stay close to the wifi router the speed is 54 mb

txpower 15 was a very small value.
In windows and linux no such problems.
 
You can't tune txpower to an arbitrary value. It is fixed by the content of the card's EEPROM, the driver uses this value and 15 looks correct.

Which FreeBSD version are you using? stable/8 has a newer driver which might help your case.

The problem in eeprom?

As I said, 15 is a correct value, you will not get more then that, not even with hardcoding it into iwn4965_set_txpower(). At least I doubt that very much..

Which txpower does Linux show? Can you post the output of the appropriate command unter Linux?

If txpower is the same under Linux the issue lies somewhere else, either within the rate control handling or maybe even missed beacons.

If downloading over the network in linux then transfer speed does not drop.
in FreeBSD falls.
What?

What arch, which driver(post link), is driver for XP, (VISTA drivers are not going to work)?

You need to provide more info if you want help.
 
i386
driver windows xp
===========================
are now being freebsd 8, and give more complete information, pciconf-lv and other information
 
The best information you could provide to me is backtrace from panic.

On 8.0 GENERIC those should be auto generated and stored in /var/crash/

Link quality is good enough, no reason to tune txpower. Could you provide the output of # wlandebug +rate +xrate and # sysctl dev.iwn.0.debug=1?

Also post your /etc/rc.conf, /boot/loader.conf, /etc/wpa_supplicant.conf and output of # ifconfig -a and # netstat -rn so can get a bit of clue what's going on.
