On this TL-WN821N v1 the one-stage (as published in binary from by Atheros, so far I had problems with my self compiled one) and two-stage firmwares work equally well on a vanilla 2.6.31 kernel: usb 1-2: new high speed USB device using ehci_hcd and address 4 usb 1-2: New USB device found, idVendor=0cf3, idProduct=9170 usb 1-2: New USB device strings: Mfr=16, Product=32, SerialNumber=48 usb 1-2: Product: USB2.0 WLAN usb 1-2: Manufacturer: ATHER usb 1-2: SerialNumber: 12345 usb 1-2: configuration #1 chosen from 1 choice usb 1-2: reset high speed USB device using ehci_hcd and address 4 usb 1-2: firmware: requesting ar9170.fw ath: EEPROM regdomain: 0x809c ath: EEPROM indicates we should expect a country code ath: doing EEPROM country->regdmn map search ath: country maps to regdmn code: 0x52 ath: Country alpha2 being used: CN ath: Regpair used: 0x52 phy2: Selected rate control algorithm 'minstrel' cfg80211: Calling CRDA for country: CN Registered led device: ar9170-phy2::tx Registered led device: ar9170-phy2::assoc usb 1-2: Atheros AR9170 is registered as 'phy2' usbcore: registered new interface driver ar9170usb udev: renamed network interface wlan2 to wlan3 cfg80211: Current regulatory domain intersected: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm) Regards Stefan Lippers-Hollmann -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
