AR9271-AL1A / AR9271L-AL3A chip versions
- The first part of the name is the chip model (AR9271 or AR9271L). In the case of this specific chip name (AR9271L), 'The L stands for "Low-Cost".', per Sujith on ath9k-devel
- The second part of the name is the package type, Lead-Free, major and minor mask revision. For example AL3A is the 3rd major chip revision. Major revisions are for bug fixes or new features requiring complete new masks (as opposed to minor revision which could be just a partial metal mask change). In the second part of the name, 'L' denotes Lead-Free package.
MIMO / Diversity nomenclature
Per the AR9271 datasheet (.. it may not be the best idea to link directly to that), a secondary antenna for Rx will use antenna diversity - there is only a single independent receiver. Current wiki convention is to ignore diversity configurations (even if implemented on-chip)
Please note: Windows drivers for AR9271 and AR7010 or AR7015 + AR9280 or AR9287 (in combinations) ARE the SAME. Furthermore Atheros doesn't include USB related drivers to the widely spread PCI-Ex related driver packages. So there is a big problem to find latest drivers for these chipsets. As usual Atheros doesn't maintain end user driver on his website (now qualcomm) As usual Atheros f...s off all requests to the device mfrs As usual Device mfrs have no clue and wish to update anything once they sold their BS As usual USB connected high bandwidth devices lead to the high CPU load As usual this lead to driver/HW hangs, BSODs and other nice things As usual Atheros driver versions varies from 2.x to 10.x, so non familiar user's head goes off on what to DL.
For a long time v184.108.40.206 stored on WikiDevi server (and most mfrs servers) was latest available to the people It include drivers: WinXP v220.127.116.11, WinVista 18.104.22.168 and Win7 22.214.171.124
Good news for all the us, I've found 2 newer versions of original (non-custom) driver and ACU versions on the ECS website. v126.96.36.199 lead to hang TP-Link TL-WN822n Ver2 (AR7010+AR9287) in my systems, not so frequently but once a day or once a week, depending on the net/CPU load I've just installed latest v188.8.131.52 for XP and it works fine for a few hours. I will look will it reduce hangs or not.
Below is full package description and links for new versions:

Includes Original (non-custom) Atheros Client Utility Please also note, that ACU setup has own copy of driver files inside the cabs, so if you prefer to install by setup folders with separate drivers are no necessary to carry on with On other hand, people who needn't heavy 40Mb ACU may get only drivers and use Windows built in WLAN util.
Please once more note that Windows drivers for AR9170 USB controller are different and not suitable for AR9271 (AR701x) and vice versa.
To admin! Please backup drivers to your site and link for particular adapters if possible, so ppl will get good service.
Good luck! - TheDrive
