Hi guys,

here's a simple fix to get rid of the annoying "unknown locale" messages in your system.log. These are caused by the TP-LINK WDN-4800 card, which has a regulatory domain value in its eeprom that is not recognized by OS X. It works by simply replacing the check for regdomain 0x37 (ETSI) by checking for the one in the EEPROM, i.e. 0x21.

Stefan, I've tried this fix on this computer, which had an "unknown locale: 21" message, and it worked, thanks! However, do you know what to do when the message is "unknown locale: 14"? I've another Hack and with this edit you provided it doesn't go away.

I finally made it
All steps were right, the problem was on iwleeprom, so i use iwleeprom from MacNB and use the flag "-r" n its write to the ROM.

Locale: FCC
Country Code:

Sir i used "00", so got FCC as locale but No Country Code , Sir wat should use regdom for INDIA.

Bit late but found out why
For new Atheros kext in High Sierra above patch is no longer working. Just spent my day why? After dissembling kext binary file I found that new plugin now using EAX register instead of EBX. So new HEX byte for clover patch

are:

FIND: 83F837

Replace: 83F821
