the 3945 and 4965 tend to be rather unreliable at 802.11n i've found.

on the 4965 the layout is a little different, will need further testing. The corresponding bytes to enable 12 - 14 channels are here. non patched file is here Attachment 2631

eeprom[0x174] = 0x2b; //was 00, 12ch
eeprom[0x175] = 0x0f; //was 00, 12ch
eeprom[0x176] = 0x2b; //was 00, 13ch
eeprom[0x177] = 0x0f; //was 00, 13ch
eeprom[0x178] = 0x2b; //was 00, 14ch
eeprom[0x179] = 0x0f; //was 00, 14ch
I have an US version of Intel 4965agn MM1 card and need to enable European channels (12 and 13). Is any way how to set this card from Linux LiveCD to work under Windows?
Thanks for any help.

I uploaded my patched dump here
Changed bytes:
eeprom[0xdc] = 0x2b; //was 00, 12ch
eeprom[0xdd] = 0x0f; //was 00, 12ch
eeprom[0xde] = 0x2b; //was 00, 13ch
eeprom[0xdf] = 0x0f; //was 00, 13ch
eeprom[0xe0] = 0x2b; //was 00, 14ch
eeprom[0xe1] = 0x0f; //was 00, 14ch
Also I changed device id (my card was for IBM laptops only), but it doesn't matter.

To sum up, eeprom structure in 3945 and newer cards differs from structure of 2200 eeprom. Also I did some reverse engineering on intel's cards and now I have method to change eeprom in driver (without soldering, like on 2200). But I can't public it here :)
I need you help...I use this card,without soldering? Can you let me know I should to do? Thanks a lot ,thanks again:)

Hi ittrium,

I've got a new Intel Centrino Advanced-N 6200 wifi card that's region locked from using channel 12+13. Is it possible to give you a dump of the eeprom for analysis?

I've an US 3945abg card and use it in EU.
My problem is, that "ethtool -e" doesn't work with actual drivers.
Who can I get EEPROM from and to card? Or can I get the patched EEPROM dump an who I can write it on my card?

Regards,

Flashing eeprom on iwl4965
 
Dear ittrium & firefighter44x,

I have an IWL4965 wit hthe same channel limitation (I can get no higher than channel 11).
I understand that with your method, you can flash the eeprom with the iwleeprom app as found on google source.

I can get a copy from my eeprom as a dump, but I have no idea what to modify (or how to do it). I read your posts, but I don't have enough knowledge about how to change this in the dump.

Could you please help me out a bit?

thanks a lot.
best regards,

Hendrik-Jan
