Driver: Qualcomm Atheros AR9285 802.11b/g/n WiFi Adapter
OS: Windows 7 Ultimate SP1 - x64
Purpose: Changing the Channel of wifi
For knowing which files are being used by the above mentioned driver, I used a tool called DriverExtractor. The result are these files:
athrextx.cat
athrx.sys
netathrx.inf
defaultIbssChannel
is the value in the netathrx.inf
that I'm interested in:
[adhocchannelselect.reg]
HKR, Ndi\params\defaultIbssChannel, ParamDesc, 0, %adhocchannel%
HKR, Ndi\params\defaultIbssChannel, default, 0, "10"
HKR, Ndi\params\defaultIbssChannel, min, 0, "1"
HKR, Ndi\params\defaultIbssChannel, max, 0, "11"
HKR, Ndi\params\defaultIbssChannel, step, 0, "1"
HKR, Ndi\params\defaultIbssChannel, base, 0, "10"
HKR, Ndi\params\defaultIbssChannel, type, 0, "int"
.
.
.
HKR, , defaultIbssChannel, 0x00002, "11"
There's no key or value in the registry as defaultIbssChannel
So I searched my whole Windows drive and find netathrx.inf
in these places:
C:\Windows\inf
C:\Windows\System32\DriverStore\FileRepository\netathrx.inf_amd64_neutral_11fc8a486f2a66fd
C:\Windows\System32\DriverStore\FileRepository\netathrx.inf_amd64_neutral_594f4aa1786993fb
C:\Windows\System32\DriverStore\FileRepository\netathrx.inf_amd64_neutral_e4fa711280ff8fd4
C:\Windows\System32\DriverStore\FileRepository\netathrx.inf_amd64_neutral_fd83bf6c5bba7e25
C:\Windows\winsxs\amd64_netathrx.inf_31bf3856ad364e35_6.1.7600.16385_none_cf0144fd71b44a1a
Finally my question is that: Which of the netathrx.inf
files in above locations should be edited so that the new value takes effect?
Update 1:
The netathrx.inf
files in the C:\Windows\System32\DriverStore\...
are the most recent one, but other locations hold the older version of the file.
