longDescription = ''
|
|
Firmware for Qualcomm Atheros cards which use the ath9k_htc.ko
|
|
Linux driver, supporting 802.11 abgn on both 2.4ghz and 5ghz
|
|
bands, 3x3-antenna MIMO, up to 600mbit/sec.
|
|
|
|
Most devices which use this driver are based on the Qualcomm
|
|
Atheros AR9271 chip, which is a PCIe device. If your device
|
|
is connected via USB, it will also include a Qualcomm Atheros
|
|
AR7010, which bridges from a USB gadget interface to a PCIe
|
|
host interface. This repository includes the firmware for
|
|
both chips.
|
|
|
|
This firmware is completely open source with no blobs, which
|
|
is quite rare in the wifi world. Wifi chips have their own
|
|
dedicated general-purpose CPUs. This source code allows you
|
|
to see what those CPUs are doing and modify their behavior.
