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.

1You can change the channel of the wifi in your Router much easier, which will force your wifi adapter to use that channel. Doing what you want to do will not change the channel as the router controls that. – Moab – 2015-06-16T14:35:23.200
It's an internal component in my laptop. There's no exterior router – wiki – 2015-06-16T15:58:05.900
It has to connect to a router, otherwise you would have to internet connection. – Moab – 2015-06-16T16:49:55.073
You might edit your question and clarify what you are trying to accomplish in the end, – Moab – 2015-06-16T16:50:37.373
it's not that much complicated, My phone needs to be connected to the internet. It uses android and so can't connect to an ad-hoc network; so I have created a wifi-hotspot with connectify and route my internet connectivity(LAN) in to it. I want to change the channel that wifi is using; right now it's 11 – wiki – 2015-06-16T16:56:24.547
Add that information to your question please. – Moab – 2015-06-16T22:22:51.837
Seem that he's trying to add an ad hoc Software AP using his WiFi adapter... – not2qubit – 2015-08-25T10:25:32.900
