Here's my configuration:
- AC-8260 WiFi module running on Linux Kernel 4.1 as Access Point.
- Windows 7 OS with AC-7260 WiFi Module as client.
- Windows 10 OS with AC-7260 WiFi Module as client.
- # 3 connects to # 1 if using the latest driver version 184.108.40.206 date: 10/31/2017. This is good. It doesn't work if using the previous version of the driver 220.127.116.11 date: 10/1/2017, but thats OK since latest driver works. But it does tell me that something changed for good in the latest driver that helps with the connectivity.
- Here is the main problem: # 2 above cannot connect to # 1 even with the latest driver version 18.104.22.168. Tried several other previous drivers but they wouldn't work either. hostapd on linux reports the following errors:
- Dec 19 02:50:27 .....daemon.notice hostapd: wlan0: STA IEEE 802.11: did not acknowledge authentication response.
Any help would be greatly appreciated.
We understand you're setting up system # 1 as the Access Point, system # 3 can connect if using the latest drivers, but system # 2 cannot connect regardless of driver version.
In order to look into this, could you please provide us with a System Support Utility report for all three systems (or at least 1 and 2).
- For Windows*:
- Download and run the http://downloadcenter.intel.com/download/25293 Intel® System Support Utility.
- Select to scan "everything," and run the scan while connected to your wireless network (if possible).
- Save the report and attach it to your reply.
- For Linux*:
- Download the https://downloadcenter.intel.com/download/26735 Intel® SSU for Linux* and save the ssu.tar.gz file to your system.
- Extract the ssu.sh file from ssu.tar.gz and save to your system.
- To run the ssu.sh script from a Linux terminal, Open Applications->Accessories->Terminal.
- From the current directory, navigate to the current folder where the ssu.sh file resides. For example, if you saved the ssu.sh file to a folder called SSU File, the command would be cd SSU File.
- Run the ssu.sh file using this command: ./ssu.sh
- If no output file is specified, the Intel® SSU writes the output to the .txt file.
- If possible, please test the following scenario and let us know the results:
- Set up system # 3 as a hotspot: Start > Settings > Network & Internet > Mobile Hotspot > Set up the hotspot and turn on "Share my Internet Connection with Other Devices."
- Connect system # 2 to # 3 and let us know if the connection is successful. This will help us identify if it's an issue specific to your Linux AP or a greater issue connecting to hotspots and hosted networks for the AC7260 in Windows* 7.
- How many systems will be connecting as clients to the system # 1 AP?
We look forward to hearing back from you.
Here's the information you requested.
- Windows SSU output attached.
- Linux SSU output attached. Note that we are running a custom Linux distribution based on Kernel 4.1; so, the SSU on Linux could not gather much information. If you need anything specific for this, please let me know.
- Tested the mobile hotspot. Works fine. I am able to ping from my Win7 to Win 10. Also, the Win 10 shows that the Win7 is connected. No problem whatsoever.
- We intend to connect 5 clients to the Linux system's WiFi AP.
Thank you. Just want to add more information:
- there is NO problem with using Ubuntu "Live USB" 16.04 LTS on the laptop (that natively has Win 7 and AC 7260). It is able to communicate without any problems with # 1. It immediately connects and stays connected.
- Even though I said, # 3 is able to communicate with # 1, I do see some times, it is not able to do that reliably.
Thanks for this update.
- If you run the live CD in PC # 1 or # 3, and set up the AP there, can # 2 still not connect if using Windows*?
- Could (or have) you tried using the wireless drivers provided by your computer manufacturer for # 2? - http://www.dell.com/support/home/us/en/19/drivers/driversdetails?driverId=48WF6 Intel® 7260 WiFi Driver for Dell Precision M6800*

We will continue investigating. However, due to the nature of this problem, we recommend for you to additionally reach out and engage your computer manufacturer as well as Linux* forums. Let us know of any updates you receive from their side.
- I went to Dell's page you linked below and tried. # 2 still cannot connect to # 1.
- Using LiveCD, i created a AP on # 3, and I can connect from # 1, no problems at all. Please note that in this case, both sides are using AC-7260.
Is there anything else you want me to try. Thanks for your support.
So far, we understand that the # 2 PC (7260/Win7*) can connect to Windows* created hotspots, and all other systems have no issues regardless of who's the client and who's the host.
- Can # 2 (7260/Win7*) connect to # 3's (7260/Win10 PC, but using Linux*) LiveCD hotspot?
- How are you creating the AP in Linux*?
- Have you tried setting up the profile on # 2 manually?
We look forward to hearing back from you.
