1 pointSeems more related to the password but, again, those cards are not worth the effort. Given the recent developments on better Broadcom M.2 cards (hint: BCM4350), you should not waste time with these poorly supported Atheros cards and switch to a supported Broadcom model.
1 pointThose issues and limitations are already clearly posted on Chunnann's original thread at InsanelyMac (see from post #21); let's not unnecessarily duplicate info here, it's best to report issues to Chunnann directly in at IM. The above facility is a mere adaptation of Chunnann's work posted here. For the record, only AR946x cards appear to run at decent speeds to date. NB: Re: macOS versions, you obviously meant 10.13 and 10.12 (not 10.3 and 10.2)
