An interesting new development:
I've confirmed it's not the antenna as I was able to acquire some more cards from a different source which work fine.
Ostensibly they are the same card: Atheros AR9462 : QCNFA222 reference design.
The output from lspci for both working and non-working cards is: "03:00.0 Network controller: Qualcomm Atheros AR9462 Wireless Network Adapter".
However the Subsystem listed in lspci is different. I don't have the exact value at the moment for the working cards, but it lists Dell and the part number DW1802. The non-working cards are AzureWave.
I've seen a lot of similar cards on ebay that I suspect are the AzureWave. A few offers on ebay are for the genuine Dell parts.
What would be the best way to compare and contrast these cards to determine if there is a way to make them work?
Inspect EEPROM? Someone previously mentioned calibration data, but I have no idea if it's possible to inspect or alter that.
